Both class I and class II antibodies were found to be significantly increased in SLE and SSc. Rather than major organ involvement, anti-HLA antibodies were associated with

the presence of other antibodies in both diseases. “
“B cells play an essential role in humoral immunity by producing antigen-specific antibodies. However, B cells also participate LEE011 in cellular immune responses by presenting antigens, providing costimulation, and producing cytokines to activate and expand effectors and memory T cell populations. Recent identification of antibody-independent functions of B cells has reawakened interest in the many roles of B cells in normal immune responses as well as in autoimmune diseases. B cells interact with other immunocompetent cells during a tightly regulated immune activation process, acting as both effector and regulator. If this balance between effector CH5424802 in vitro and regulatory B cell functions is disrupted, harmful effects of immune activation such as autoimmunity can occur. In this review, we will discuss the role of human peripheral immature B cells in normal immune responses as a modulator of autoimmunity. We will also discuss abnormalities of these cells in pathogenesis of systemic autoimmunity with particular focus on systemic lupus erythematosus pathogenesis. “
“To describe the clinical characteristics, serologic, radiological and clinical disease activity, and

modality of therapy in patients with rheumatoid arthritis (RA) at tertiary outpatient care in Qatar. The study design was cross-sectional Wilson disease protein where 100 consecutive cases who met 1987 American College of Rheumatology criteria for diagnosis of RA were enrolled in this study. Demographic data (sex, nationality and age) numbers of swollen and tender joints, X-rays and current medications were collected during outpatients visits to Hamad General Hospital. Disease Activity Score of 28 joints (DAS28) and Health Assessment Questionnaires (HAQ) scores were calculated. All patients with RA who were

seen as rheumatology outpatients were invited to participate in the study. One hundred patients were seen and examined during their follow-up at the outpatient clinic; data were collected and analyzed. Females represented 67% of all patients, 6% had more than six swollen joints, 9% had more than six tender joints. DAS28 and erythrocyte sedimentation rate (DAS28) calculation revealed 49% of patients were in remission (DAS28 < 2.6), 15% had low disease activity (DAS28 2.6–3.2) and 36% had DAS28 > 3.2.Mean HAQ score was 1.02. Rheumatoid factor (RF) was positive in 63%, while anti-cyclic citrullinated protein antibody (anti-CCP) was positive in 71%, and 49% were positive for both. Radiography of hands and feet during the previous year was done in 65% of patients: 11% of them had erosions. Sixty-six percent were on one synthetic disease-modifying anti-rheumatic drug (DMARD) and 27% where on more than one synthetic DMARD and 7% where on no DMRD.

Thirty-four patients with knee osteoarthritis were detected with

Thirty-four patients with knee osteoarthritis were detected with joint effusion by clinical examination. Both knee joints were examined using plain radiographs and ultrasonography. Questions were obtained for visual analog scale (VAS), Western Ontario McMaster Universities Osteoarthritis Smad inhibitor Index and Health Assessment Questionnaire (HAQ). Synovial fluid (SF) and serum levels of vascular endothelial growth factor (VEGF), matrix metalloproteinase

(MMP)-13, leptin, resistin and cartilage oligomeric matrix protein (COMP) were measured using enzyme-linked immunosorbent assay. Synovial fluid VEGF level was positively correlated with Kellgren–Lawrence (KL) grades and it was higher in patients with KL grade 4 than those with KL grade 2. SF VEGF correlated with ultrasonographic findings, such as the length of medial

osteophytes. The amount of effusion was positively correlated with SF resistin. Serum leptin level had positive correlation with HAQ and the length of medial osteophytes. MMP-13 or COMP levels were not correlated with radiographic or ultrasonographic findings. Synovial fluid VEGF level was correlated with radiographic grading, ultrasonographic findings and functional statues in knee osteoarthritis, and serum leptin level also correlated with the ultrasonographic findings and functional status of knee osteoarthritis. “
“Dear Friends, IJRD is APLAR’s vehicle to showcase the global science and art of Rheumatology. Our priorities are relevant and up-to-date reviews, randomised trials and meta-analysis, ICG-001 in vitro very large case series, Grand Round cases, Novel

Hypothesis, review of top publications in rheumatology within the last 2 months, Milestones in Rheumatology, Post graduate quiz, correspondence, News and views from APLAR region and other newly proposed features of IJRD (please see the journal’s website). We are committed to and doing our best to speed up the review process. While our Editorial team and Reviewers are reminded to be prompt, they do not act in haste. These expert minds selflessly carry out critical appraisal of manuscripts with extra- caution, without any prejudice or Methocarbamol conflict of interest. However, we have to, at times, apply the harsh option of immediate rejection; it does not always mean poor methodology, lack of novelty, plagiarism or poor English. It may simply mean low priority in the light of a large number of submissions. With more pages and 8 issues from next year including proposed special issues on Lupus, Takayasu arteritis, Sjogren’s syndrome, Infections in Rheumatic diseases, Imaging in Rheumatology and spondyloarthropathies over the next 2 years, we are hoping to enrich the journal further with your contributions. Let us all rise for the cause of futuristic and relevant Rheumatology and above all, for the welfare of our patients. Look forward to your constructive feedback to achieve these goals.

, 2005; Miot & Betton, 2007). CpxP has no obligatory function for the induction of the Cpx response (Raivio et al., 1999; DiGiuseppe & Silhavy, 2003). However, the cpxP gene was identified as a CpxR target involved in inhibiting the expression of toxic envelope proteins, including misfolded pilus subunits of P-pili that are crucial for uropathogenic E. coli (UPEC) during kidney colonization (Jones et al., 1997; Danese et al., 1998; Hung et al., 2001; Isaac et al., 2005). In agreement with its function Ku-0059436 in quality control for subunits of surface appendages, CpxP is also involved in the early steps of biofilm

formation (Beloin et al., 2004; Yang et al., 2008). Biochemical analysis of the reconstituted CpxAR phosphorylation cascade demonstrated that CpxP, incorporated into the lumen of the proteoliposomes, inhibits the autophosphorylation of CpxA (Fleischer et al., 2007). As the reconstituted system excludes the involvement of other factors, this finding indicates a direct protein–protein interaction between CpxP and CpxA (Fleischer et al., 2007; Zhou et al., 2011). In support of this, peptide library

screens showed that the purified PSD of CpxA directly interacts with CpxP (Zhou et al., Selleck PI3K Inhibitor Library 2011). Interestingly, the interaction of purified CpxP with peptides derived from the PSD of CpxA depends on negative charges within this domain (Zhou et al., 2011). The crystal structure of CpxP gave further insight into this interaction (Thede et al., 2011; Zhou et al., 2011). CpxP consists of a dimer, the monomers of which are interwined like ‘left hands’ (Thede et al., 2011; Zhou et al., 2011). Thereby, each monomer is strengthened by double hydrogen bonds between two highly conserved LTxxQ repeat motifs. Based on the structural and biochemical analysis, CpxP-mediated Cpx inhibition results from

an interaction between the concave polar surface of CpxP and the negatively charged sensor domain of CpxA (Fig. 3a; Zhou et al., 2011). The CpxP dimer acts as a patch to shield the CpxA sensor domain from inducing signals, maintaining Etofibrate the SK in an ‘off’ mode. Moreover, the structure of CpxP provides explanations of how CpxP might act as a sensor for salt (Zhou et al., 2011), pH (Thede et al., 2011) and misfolded pilus subunits (Zhou et al., 2011) for the Cpx system. Physicochemical and chemical stimuli inducing the Cpx response include alkaline pH, salt (Raivio & Silhavy, 1997), depletion of the major lipid phosphatidylethanolamine (Mileykovskaya & Dowhan, 1997), attachment to hydrophobic surfaces (Otto & Silhavy, 2002), intermediates of the acetyl-CoA pathway (Wolfe et al., 2008; Lima et al., 2011), low cAMP levels (Strozen et al., 2005), carbon monoxide (Davidge et al., 2009), metals (Lee et al., 2005; Yamamoto & Ishihama, 2006), indole (Raffa & Raivio, 2002), alcohols, acetone and the anaesthetics procaine and phenethyl alcohol (Clarke & Voigt, 2011; Table 1).

Serology is useful since this kind of patient has not had any previous contact with the fungus. All traveler patients diagnosed in our laboratory had a positive immunodiffusion test. RT-PCR was positive in only five of the nine patients studied, probably due to the limited amount of DNA circulating in immunocompetent

PD0332991 cost patients. Respiratory samples provided better results than sera or blood samples. For most patients, only sera samples were available for reaching diagnosis, a fact which could explain the low sensitivity of RT-PCR in the case of travelers. More studies should be performed on this kind of patient. Finally, the fungi were never cultured. In immigrant cases, we found mainly disseminated histoplasmosis in immunosuppressed patients. Histoplasmosis

occurred as a result of the reactivation VX-809 molecular weight of a latent focus of infection acquired years earlier.30 A total of 29 out of 30 immigrants had AIDS as an underlying disease. This figure matches previously reported studies.31 Patients with disseminated histoplasmosis present fever, weight loss, anorexia, cough, vomiting, diarrhea, and abdominal pain.6 Only 8 patients out of 20 had a positive result in a serological test. In 73% (22/30) of cases the fungus was isolated. Cultures showed good sensitivity in detecting H capsulatum; however, the average time needed to obtain positive cultures was 15 days. RT-PCR showed good sensitivity (89%). The technique

was performed in 27 patients and was positive in 24. Respiratory samples and biopsies were the most useful samples, with 100% sensitivity. Blood samples appeared to have lower sensitivity than sera samples (37.5% vs 69%); however, we obtained a positive result for sera sample and a negative result for blood only in patients 15 and 11 (Table 4). In these cases there may be a partial inhibition which was reflected in a slightly lower melting curve for the internal control. In the other cases, sera and blood samples were either both negative (Table 3, patient 9; and Table 4, patients 1, 18, and 20) or both positive (Table 2, patients 19 and 21). These results may correlate with the clinical status of each patient. More blood samples should therefore selleck chemicals be analyzed to reach a conclusion. PCM in non-endemic areas is rarely suspected because of the extremely long silent period of this disease.9 Diagnosis was delayed in four of the six cases diagnosed in our laboratory; we have no data on the other two cases. In all cases described in this paper characteristic yeasts were visualized at the hospitals. The fungus was cultured in only one case (patient 5) and growth was very slow. Serology proved to be useful since it was positive in all patients. RT-PCR showed good sensitivity as we obtained positive results for all patients. Respiratory and biopsy samples proved more suitable than blood samples.

, 1990; Itin et al., 1998). This species can contaminate antiseptic creams and (skin) lotions, sodium bicarbonate solutions used as a neutralizing agent for a sodium hydroxide sterilizer for artificial lenses, Selleck INCB024360 and colonize materials such as catheters and plastic implants (Pettit et al., 1980; Orth et al., 1996; Itin et al., 1998). A 3-year surveillance study showed that Purpureocillium lilacinum was frequently found in water distribution system of a bone marrow transplantation unit. Purpureocillium lilacinum positive sites included water from water tanks and showers, sinks, showers (including drains), toilets and air. This species can thrive on wet and moist surfaces

of water distribution

systems and form a biofilm, together with other species such as Aspergillus, Fusarium and Acremonium (Anaissie et al., 2003). Although biofilm formation by filamentous fungi has been poorly studied, it is postulated that adhesion, colonization and matrix formation are key criteria in the biofilm formation process (Martinez & Fries, 2010). The capacity of Purpureocillium lilacinum to adhere to the waxy host cuticle of nematodes and its ability to colonize surfaces under harsh conditions with low nutrient concentrations (fungal biofilters, plastics) and low oxygen levels (Mountfort Sorafenib ic50 & Rhodes, 1991; Vigueras et al., 2008) suggested that this species is able to form a biofilm. Concordant with our results, Okada et al. (1995) showed that Purpureocillium

lilacinum is a dimorphic species and is able to form an Acremonium-state in and/or on agar media. This Acremonium-state phenotypically resembles Fusarium solani, a fungal pathogen causing severe corneal disease and the causal agent of an outbreak of lens-associated keratitis. Remarkably, the most frequent manifestation of Purpureocillium lilacinum is also keratitis (Pastor & Guarro, 2006), suggesting that both species might have similar properties besides their phenotypic similarity. In this respect, it needs to be noted that Imamura et al. (2008) showed that F. solani has the ability to form biofilms on lenses; however, this appears to be strain rather than species dependent. Paecilomyces Oxymatrine can cause hyalohyphomycosis, and two species, Purpureocillium lilacinum (=P. lilacinus) and P. variotii, are the most frequently encountered (Walsh et al., 2004; Houbraken et al., 2010). The phylogenies described here and elsewhere explain why some treatments will work for one species and fail for the others. Major differences in antifungal susceptibility profiles were found between P. variotii and Purpureocillium lilacinum in vitro. Amphotericin B showed good activity against P. variotii and related species in vitro, as was the case for flucytosine (Aguilar et al., 1998; Castelli et al., 2008; Houbraken et al., 2010).

Plasmids and primers used in this study are listed in Table 2 Mi

Plasmids and primers used in this study are listed in Table 2. Minimal inhibitory concentrations (MICs) of various antibiotics were determined by microdilution as described previously (Nishi et al., 2004). Oxacillin, bacitracin and vancomycin (Sigma Sunitinib price Chemical Co. Ltd, St. Louis, MO), as well as erythromycin and ofloxacin (Wako Pure Chemical Industries Ltd., Osaka, Japan), were used. Population analysis profiles were determined by plating appropriate dilutions of an overnight culture on plates containing various concentrations of bacitracin (Nishi et al., 2004). Colonies were counted after 48 h incubation at 37 °C. All susceptibility tests were

repeated at least three times to check the reproducibility of the results. A small portion of overnight culture of S. aureus was inoculated to fresh TSB. Then, S. aureus cells were grown at 37 °C with shaking. Various concentrations (0.5, 1, 8, 16 μg mL−1) of bacitracin were added to the medium when OD 660 nm reached 0.3. After 5, 15, 30 and 60 min, the cells were

collected. Total RNA was extracted with a FastRNA Pro Blue kit (MP Biomedicals, Ohio) in accordance with the manufacturer’s protocol. One microgram of total RNA was reverse-transcribed to cDNA using a first-strand cDNA synthesis kit (Roche, click here Tokyo, Japan). Using cDNA as template DNA, quantitative PCR was performed using LightCycler system (Roche). Primers for bceR, bceA, vraD, vraF and vraR were constructed and used to determine optimal conditions for analysis of their expression. The amount

of gyrA was used as internal control. Primers for quantitative PCR are listed in Table 2. All mutants used in this study were shown in Table 1. Table 3 shows the MIC results of the mutants against various antibiotics. In MW2-derived ABC transporter mutants, the MIC of bacitracin in MM02 (ΔbceAB), MM07 (ΔbceB) and MM03 (ΔvraDE), showed two- and fourfold reductions, respectively, compared with that of the wild type, while the MIC of MM01 (ΔvraFG) showed a similar level to that of the wild type. Also, the MIC of bacitracin in a TCS mutant, MM08 (ΔbceS), was reduced fourfold compared with that of the wild type, showing a similar result with that of FK77 (ΔbceRS). In addition, two RN4220-derived filipin mutants, MM05 (ΔbceAB) and MM06 (ΔvraDE), showed increased susceptibility to bacitracin (fourfold reduction in MM05, 16-fold reduction in MM06), while another mutant MM04 (ΔvraFG) showed no change. For the complementation experiment, three complementation strains (MM09, MM10 and MM11) showed a similar susceptibility to bacitracin with that of the wild type (Table 3). MIC of oxacillin in MM02 (ΔbceAB) showed twofold reduction, while that of MM05 showed no alteration. Also, MIC of vancomycin in MM01 and MM04 (ΔvraFG) showed twofold reduction. MICs of the mutants against erythromycin and ofloxacin were similar to that of the wild type.

Investigators, study coordinators,

and subjects were blinded to treatment assignment. After initiating the study drug, subjects were Sirolimus cost asked to maintain a daily diary to record details regarding medication compliance, geographic location, and number of loose stools, symptoms, and daily eating habits. Subjects were asked to grade their symptoms (Appendix, Table A1). The study coordinator contacted the patient within 7 days of their return from the trip to monitor for toxicity, study outcomes, and reminded subjects to submit a fresh stool sample within 5–7 days of the last study dose. Adverse event (AE) monitoring was done via the daily diary and the final phone interview. An AE was defined as any untoward medical occurrence in a study subject exposed to AKSB or placebo. An AE could be any unfavorable and unintended effect (including an abnormal laboratory finding), symptom,

or disease temporally associated with the use of AKSB or placebo. Serious adverse events (SAEs) were defined as those that were life-threatening, resulted in hospitalizations of >24-hour duration, or were disabling or resulted in death. All AEs were assessed whether they were possibly, probably, or definitely related to the study drug or not related at all. All SAEs were to be reported to the IRB within 24 hours and all other AEs were summarized in annual reports to the IRB. Unused capsules AZD5363 price from subjects on AKSB were returned to Agri-King, Inc. for probiotic viability studies. Subjects

received a $50 honorarium for the inconvenience of participating in the study. All subjects were asked to submit a fresh stool specimen in a Para-Pak culture pheromone and sensitivity vial within 5–7 days of returning home from their trip. The specimens were submitted for culture of enteric pathogens (Campylobacter species, Salmonella, Shigella, Aeromonas, and Yersinia), enterotoxigenic E coli toxin assay, and ova and parasite examination at the Mayo Clinic Microbiology Laboratory. The fecal specimen was inoculated onto selective media designed to inhibit growth of normal bowel flora while allowing growth of the enteric pathogens. The following media were used: sheep blood agar, Hektoen enteric agar, eosin-methylene blue agar, Campylobacter agar, cefsulodin-irgasan-novobiocin agar, and the enrichment broth, selenite F. Suspect colonies were identified using conventional biochemical and serologic methods. These tests were performed per standards set by the Clinical and Laboratory Standards Institute. Returned capsules were analyzed for AKSB organisms’ post-travel viability (Analab Laboratories, Fulton, IL, USA). The primary endpoint was the development of diarrhea. Assuming that the frequency of TD is 25% in those receiving placebo, 348 volunteers (174 placebo and 174 AKSB) were required to have an 85% power to detect a 50% reduction in the frequency of TD for the AKSB group (based on a comparison of 25% vs 12.5%, using a two-sided, α = 0.05 level test).

Pro-active screening for intended travel activities can identify

Pro-active screening for intended travel activities can identify future VFR travelers and ascertain potentially high-risk itineraries, thereby enabling selleck chemical education regarding the importance of accessing competent pre-travel medicine services. Immigrants from low-income countries frequently travel with their families to their place of origin to visit

friends and relatives (VFRs), and account for a significant proportion of international travelers.1,2 Compared with other travelers, VFRs are at greater risk of contracting many travel-related illnesses,3 in part because of insufficient use of preventive travel medicine services.1–5 In the United States, healthy children often access health-care systems for routine health exams, and these encounters afford an opportunity to screen for anticipated international travel. We surveyed immigrant families (parent’s country of birth located in a malaria-endemic zone) to determine the frequency of impending travel and to evaluate for factors associated with these travel plans. AZD8055 Bronx-Lebanon Hospital Center is a 958-bed teaching hospital. It is

one of the largest outpatient health-care providers in the South and Central Bronx. The Bronx is one of the most diverse counties in the United States with about 32.7% of its 1.4 million residents foreign-born.6 Although 75.1, 8.3, and 7.9% of the foreign-born in the Bronx were born in Latin America, Africa, or Asia, respectively, there is a large West-African community within the immediate catchment Rucaparib solubility dmso area of the Bronx-Lebanon Hospital Center.6 The main pediatric outpatient clinic located in the hospital building provides routine general health care for children from birth to 21 years of age (15,000–18,000 annual patient visits); 65% of the families are

of Hispanic and Latino and 10% to 15% of West-African heritage. Parents were approached in the waiting areas with copies of the Centers for Disease Control and Prevention-malaria endemic regions maps between September and December 2006.7 Parents who were born in a malaria-endemic country and presented to the clinic with one of their children for a routine pediatric health maintenance visit were eligible for participation. After signing an informed consent, a 20-item standardized questionnaire on anticipated travel activity and malaria-relevant knowledge, attitude, and practices (KAP) was administered by a study investigator. Parental factors associated with plans to travel with their child within 12 months from the routine pediatric outpatient visit were investigated using logistic regression. Variables considered in the multivariable model were gender, age, country of birth, period of stay in the United States since immigration, education, access to Internet, history of previous travel to country of origin, number of children, and residence of at least one child abroad. Statistical significance was set at p < 0.05, two-tailed.

Here, we report that hippocampal network activity can induce calcium transients (CaTs) in newborn GCs during the first post-mitotic week via GABAergic inputs. The GABA-induced CaTs were mediated mainly by L-type Ca2+ channels. Furthermore, we found that inhibiting any step in the signaling pathway, network activity GABA L-type Ca2+ channels, selectively suppressed the axonal outgrowth and pruning of newborn GCs, but not dendritic outgrowth. The GABAA receptor blocker bicuculline significantly suppressed axonal outgrowth, despite increasing

network activity, thus indicating an essential role of GABAergic inputs. Therefore, we conclude that network activity-dependent GABAergic inputs open L-type Ca2+ channels and BGB324 concentration promote axonal outgrowth in newborn GC during the first post-mitotic week. “
“The circadian clock, located in the suprachiasmatic nucleus (SCN), receives a major afferent from the median raphe nucleus (MRN). In the Syrian hamster, only about 50% of the cells giving rise

to this afferent contain serotonin. There is mixed evidence as to whether the serotonergic portion of this projection is involved in non-photic phase shifting of circadian locomotor rhythms. In order to better characterize the non-serotonergic projections, we conducted retrograde tract tracing using the beta subunit of cholera toxin combined with multi-label immunohistochemistry. oxyclozanide Similar to previous findings, almost half of the retrogradely selleck screening library labeled cells contained serotonin. Additionally, approximately 30% of the retrogradely labeled cells contained vesicular glutamate transporter 3 (VGLUT3), but not serotonin. Surprisingly, some dorsal raphe cholera toxin labeling was also noted, particularly in animals with central-SCN injections. To determine if the non-serotonergic projections were important for non-photic phase shifts elicited by MRN stimulation, the MRN was electrically stimulated in animals pretreated with SCN injection of

either the serotonin neurotoxin 5,7-dihydroxytryptamine or vehicle control. Intact animals phase advanced to midday electrical stimulation of the raphe while lesioned animals did not. Together, these results show that although some of the non-serotonergic raphe projections to the SCN contain VGLUT3, it is the serotonergic raphe innervation of the SCN that is critical for non-photic phase shifting elicited by MRN stimulation. “
“Recent evidence supports an emerging role of β-nicotinamide adenine dinucleotide (β-NAD+) as a novel neurotransmitter and neuromodulator in the peripheral nervous system –β-NAD+ is released in nerve-smooth muscle preparations and adrenal chromaffin cells in a manner characteristic of a neurotransmitter.

check details However, despite this wealth of data, the mechanisms underlying enduring immune and inflammatory responses in temporal lobe epilepsy (TLE) remain largely elusive. As described in the current issue of EJN, Aronica et al. (2010) took an important step toward resolving this issue. They demonstrated the selective up-regulation of a proinflammatory signalling-associated microRNA (miRNA) in a rat model of TLE as well as in human TLE. MicroRNAs are genomically encoded small non-coding RNAs that influence the translation and stability of mRNAs (Zhao & Srivastava, 2007). Aronica et al. (2010) focused on miR-146a, a microRNA that is induced by pro-inflammatory stimuli, modulating innate immunity through regulation of Toll-like receptor signaling and cytokine responses (Taganov et al., 2006). miR-146a is also known to play a functional role in T lymphocyte-mediated immune responses (Curtale et al., 2010). In order to understand the regulation and function of miR-146a in epilepsy, Aronica

et al. (2010) investigated the dynamics of miR-146a expression during epileptogenesis in a rat model of TLE. Furthermore, they studied Galunisertib cell line the expression and cellular distribution of this microRNA in hippocampal tissue obtained from TLE patients with hippocampal sclerosis. The authors report an increase of miR-146a expression in the CA3 region of rats during latent and chronic phases of experimental epilepsy, as well as in the human tissue. It is important to note that miR-146a expression was evident not only in neurons, but most prominently in GFAP-positive reactive astrocytes, underscoring their key role for orchestrating inflammatory responses in epilepsy. The results of this study IMP dehydrogenase suggest new avenues toward the identification of cellular mechanisms underlying epileptogenesis and persistent functional alterations in chronic epilepsy.

Furthermore, these results indicate that miRNAs, linking astrocytes with inflammatory mechanisms, are potentially promising new cellular targets for the development of antiepileptic drugs. “
“Cell therapy for spinal cord injury (SCI) is a promising strategy for clinical application. Both bone marrow mesenchymal stromal cells (MSCs; also known as bone marrow-derived ‘mesenchymal stem cells’) and olfactory ensheathing cells (OECs) have demonstrated beneficial effects following transplantation in animal models of SCI. However, due to the large number of affecting parameters that determine the therapy success and the lack of methodological consensus, the comparison of different works is difficult. Therefore, we compared the effects of MSC and OEC transplants at early or delayed time after a spinal cord contusion injury in the rat.
