Serial measurements of sFlt-1/PlGF ratio suggested pre-eclampsia was unlikely. We compared the results to post partum specimens collected from previous women with varying HDP. The events would be consistent with PRES due to cerebral traction trauma secondary to spinal fluid leak. Conclusions: This case report highlights the utility of measuring circulating angiogenic markers in clarifying the cause of post partum seizures. This is the first case where post partum PRES secondary to epidural anaesthesia has been

described with the use of sFlt-1/PlGF to help reach the diagnosis. 300 PROPYLTHIOURACIL Tanespimycin cost INDUCED ANTI-NEUTROPHIL CYTOPLASMIC ANTIBODY (ANCA) VASCULITIS V LIM, A DAVID, S TOOMBES, S VENUTHURUPALLI Renal Medicine, Toowoomba Hospital, Toowoomba, Queensland, Australia Aim: To present a case of Propylthiouracil induced anti-neutrophil cytoplasmic antibody vasculitis (AAV). Background: Propylthiouracil (PTU) is commonly used to treat hyperthyroidism. PTU is known to be associated with AAV. PTU induced vasculitis differs from primary AAV as being common in younger

patients with a milder course although fatal cases were described especially when diagnosis was delayed. Case Report: A 58 year old lady presented with one month history of haematuria, increasing polyarthralgia on a background of rheumatoid arthritis Dorsomorphin for six years. She noticed progressive dyspnoea for the last eighteen months and skin lesions over three years. She was

diagnosed to have multinodular goitre with thyrotoxicosis in 2006. She was initially treated with Carbimazole but changed to PTU due to nausea since 2010. Her thyrotoxicosis was controlled successfully with PTU. She had normal renal functions during these years. Initial investigations revealed elevated serum creatinine Resveratrol with proteinuria and haematuria, microcytic anaemia and raised inflammatory markers. She tested positive for both PR3 and MPO ANCAs, anti-nuclear antibody and anti-cyclic citrulline peptide antibody. High resolution computed tomography showed ground glass opacities in lungs fields. With her clinical presentation and investigations, PTU induced AAV involving skin, lungs and kidney was considered. PTU was ceased and she was commenced on Prednisolone and Cyclophosphamide. Kidney biopsy revealed features of acute tubular injury with red cell casts and minimal immunofluorescent reactivity for IgG and C3. There were no crescents or necrotising lesions. Electron microscopy is pending. Her renal function was stabilised following treatment with improvement of respiratory and cutaneous symptoms. Conclusions: ANCA-positive multisystem involvement can be observed following treatment of PTU and requires a high index of suspicion for early detection and treatment.

Herein we present the internal validation results from the virtual NOD mouse. For comparison against features of

untreated pathogenesis, we compared simulations against data on cellular expansion in the PLN, cellular infiltration and accumulation in the islets, and timing and dynamics of frank diabetes onset [13,16,30,37,80–85]. The simulated cellular profiles for CD4+ T lymphocytes, CD8+ T lymphocytes, B lymphocytes and DCs in the PLN (Fig. 4) BMN 673 datasheet and islets (Fig. 5) match the reported data closely. Furthermore, the untreated virtual mouse develops diabetes at 19 weeks, within the age range reported for both Taconic and The Jackson Laboratory, and with rapid loss of glycaemic control similar to experimentally observed dynamics (Fig. 6). Meaningful constraints on the physiologically based representation are set by the hypoxia-inducible factor pathway requirement that a single parameterization (i.e. a virtual NOD mouse) reproduces

responses to multiple and varied interventions. The simulated interventions included those targeting cell populations (anti-CD8) and cytokine activity [interleukin (IL)-10], inducing protection early but not late (liposomal dichloromethylene diphosphonate, LipCl2MDP), exacerbating disease (anti-B7·1/B7·2) and inducing remission (anti-CD3). A pharmacokinetic (PK) and pharmacodynamic (PD) representation of each selected intervention was implemented based on public data. More specifically, model inputs included the dose, dose–frequency and timing (age) of administration. Half-lives and distribution of compounds were set to reproduce the reported serum PK. Tissue concentrations were governed by a partition coefficient, which reflected available data on tissue concentration of the compound and/or general properties based on molecular weight. PD was based on direct in vivo or in vitro reported effects cAMP (e.g. depletion of CD8+ T cells by anti-CD8). All protocols (n = 16 total) reporting diabetes incidence were simulated. As dictated by the internal validation objectives, the virtual NOD mouse was developed to reproduce the

reported majority outcome for all intervention protocols. More specifically, parameterization of the intervention PK/PD and if necessary, the underlying biological representation were adjusted until simulations produced the desired behaviour. Parameters were adjusted only within the reported variability. While theoretically many parameters may be adjusted, at the conclusion, the virtual mouse comprises a single set of fixed parameters that reproduces faithfully biological responses to a diverse set of experimental manipulations (Table 3). Internal validation serves as model training, and it can also provide insight into the contributions of pathogenic and regulatory pathways. For example, LipCl2MDP, which is taken up by phagocytic cells and induces their apoptosis, has been tested at different stages of disease [86,87].

It may appear complex and driven by technical

language. At its heart, however, it asks a simple question: in the circumstance of this patient what is the right thing to do? An approach based on the key ethical principles provides a structure in the decision-making process around the appropriateness of dialysis; in this way ethics can lead to better and more nuanced decision-making. Several guidelines on the initiation of and withdrawal from dialysis provide assistance in these deliberations, including the (USA) RPA guidelines and to a lesser extent the CARI guidelines. Each of the bioethical principles is important. Autonomy does not override the other principles. All clinicians, including Nephrologists, have a responsibility to carefully balance the benefits and burdens

of treatment, including dialysis, and communicate that recommendation to the patient and family. The wishes and values of a patient should Palbociclib nmr be considered but they should not, taken alone, be determinative. This issue arises when a patient or family wants treatment that is not felt U0126 price to be appropriate by the nephrologist. In difficult cases Nephrologists should seek the advice and formal opinion of colleagues and, where available, a Bioethicist. This is particularly useful when conflict arises within families about which treatment pathway should be adopted. Advance care planning is a process of patient-centred discussion, ideally involving family/significant others, to assist the patient to understand how their illness might affect them, identify their goals and establish how medical treatment might help them to achieve these. An individual must be competent to make decisions about their healthcare in order to participate in Advance Care Planning. Advance Care Planning discussions may result in the formulation mafosfamide of an Advance Care Plan which articulates the individual’s wishes, preferences, values and goals relevant to their current and future health care.

An Advance Care Plan is only one useful outcome from the Advance Care Planning process, the education of patient and family around prognosis and treatment options is likely to be beneficial whether or not a plan is written or the individual loses decision-making capacity at the end of life. Advance care planning should be available to all patients with CKD, including ESKD on renal replacement therapy. Such plans need to be reviewed regularly as patients’ circumstances may change. Advance care planning provides benefits to patients as their end of life wishes are more likely to be known and followed when individuals have been through the Advance Care Planning process; feelings of isolation and lack of hope may be experienced when individuals are not able to honestly and openly discuss their hopes and fears for the future with loved ones. Having Advance care discussions does not result in loss of hope for patients.

Methods: The study was performed on 92 diabetes mellitus (DM) with different levels of UAlb and certain range of serum creatinine (Scr < 106 μmol/L). According to albumin-to-creatinine

ratio (ACR) in urine, all patients were categorized into 3 groups, normoalbuminuria group, microalbuminuria group and macroalbuminuria group. In addition to UAlb, Scr and ACR, levels of tubular biomarkers including urinary N-acety1-β-D-glucosaminidase (UNAG), urinary retinal binding protein (URBP) and urinary cystatin C (UCysC) were tested respectively before renal protective drugs intervention. Results: Compared with normoalbuminuria group, levels of UNAG, URBP and UCysC in microalbuminuria group and macroalbuminuria group were significantly find more different (P < 0.01). Along with UAlb, stepwise increases in levels of UNAG, URBP and UCysC were detected respectively in two abnormoalbuminuria groups. Moreover, in univariate analysis, there was immediate relevance between UAlb, ACR and tubular biomarkers including UNAG (r = 0.706, P < 0.01; r = 0.808, P < 0.001), URBP (r = 0.687, P < 0.01; r = 0.701, P < 0.001) and UCysC (r = 0.727, P < 0.01; r = 0.790, P < 0.001) in all groups. In addition, we found that UNAG was positively

correlated with URBP (r = 0.652, P = 0.000) and UCysC (r = 0.785, P = 0.000). URBP was also definitely related to UCysC (r = 0.673, P = 0.000). Multivariate logistic regression GSK1120212 research buy showed that body mass index and fasting Carnitine palmitoyltransferase II blood glucose were two predictive factors of increased UCysC. Conclusions: At early stage of DN, increased levels of UNAG, URBP and UCysC are independently associated with UAlb, and that, these urinary tubular biomarkers, similar to UAlb, may be widely used as practical targets in clinic in detecting and managing DN, and predicting renal tubular damaged progression.

glomerata is a freshwater macroalga that has been widely grown in Nan and Kong Rivers, north of Thailand. Previous studies indicated that Cladophora glomerata extract (CGE) exhibited anti-gastric ulcer, anti-inflammatory, analgesic, hypotensive, and antioxidant activities. However, the effect of CGE on a particular disease is limited. The present study investigated the beneficial effects of CGE in renal transport function of type 2 diabetes mellitus (T2DM) rats. Methods: Diabetic rats were induced by a combination of high fat diet (60% fat of total energy) ad libitum and low-single dose of streptozotocin (40 mg/kg BW). T2DM rats were subsequently fed daily with CGE (1 g/kg BW of CGE), high fat diet, or 200 mg/kg BW of vitamin C for 12 weeks.

The supernatant was used directly after clarification in some experiments, or in some cases, the fusion proteins were purified via the 6 × Histidine tag using Nickel-NTA agarose beads (Qiagen, Valencia, CA) and Poly-Prep® Chromatography

columns (BioRad, Hercules, CA) using the manufacturer’s recommendations. Interleukin-2 or the IL-2Rα chain was detected using either the anti-IL-2 monoclonal antibody (JES6-1A12; BD Pharmingen) or the anti-mouse IL-2Rα monoclonal antibody (PC61; BD Pharmingen), respectively. Wells of a 96-well plate were coated with either antibody (2·5 μg/ml) in PBS. Wells were blocked with 5% non-fat milk in PBS with 0·2% Tween (PBS-M-Tw) and fusion proteins were added for 1–2 hr at 37°. After click here washing, an anti-mouse IL-2 ALK signaling pathway biotin-labelled antibody (JES5H4; BD Pharmingen) was added and binding was detected using Strepavidin HRP (Southern Biotechnology Associates, Birmingham, AL). The ELISA plate was developed by adding 50 μl o-phenylenediamine (Sigma-Aldrich) in 0·1 m citrate buffer pH

4·5 and 0·04% H2O2, stopped by adding 50 μl/well 2 M H2SO4 and the absorbance was read at 490 nm. Immunoblot analyses were performed as reported previously with minor modifications.27 The following monoclonal antibodies were used: rat anti-mouse IL-2 antibody (JES6-1A12; BD Pharmingen), rat anti-mouse IL-2Rα (PC61; BD Pharmingen), and mouse anti-6 × His monoclonal antibody (MM5-156P; Covance, Princeton, NJ). Detection was performed using a goat anti-rat

HRP-conjugated antibody (Jackson Immuno Research, West Grove, PA) and developed using the Amersham ECL Plus Western blotting detection reagent (GE Healthcare) following the manufacturer’s recommendations. A determination of fusion protein concentration Amrubicin was established using immunoblot analyses and quantitative densitometry and compared with recombinant IL-2. For MMP immunoblot analyses, extracts or supernatants were probed with goat anti-mouse MMP2 or MMP9 antibodies (R&D Systems, Minneapolis, MN). Fusion proteins were digested with PSA (Cortex Biochem, San Leandro, CA) or prostate extracts in 50 mm Tris–HCl, 100 mm NaCl pH 7·8 at 37°. For digestion of the fusion protein containing the MMP cleavage sequence, MMP9 or MMP2 (R&D Systems) was activated with p-aminophenylmercuric acetate and this activated protease or equivalent amount of activating solution without the protease was used to digest the fusion protein for 1 hr at 37° for MMP9 and 10 min for MMP2. Aliquots of digests were loaded on 15% Laemmli gels for Western blotting.

When mice treated with 22D1 mAb were inoculated i.p. with HK-C. albicans, oxidative burst by rpMϕ was significantly reduced (Fig. 4D middle and right panels), demonstrating that SIGNR1 plays a role in oxidative burst INCB024360 mouse at least in rpMϕ. To confirm the interaction of SIGNR1 with Dectin-1 in rpMϕ, we stained the cells with specific Ab before and after the addition of HK- or live C. albicans. Co-localization of SIGNR1 and Dectin-1 was very limited without microbes, but their accumulation at the contact site with HK- and live microbes

on phagosomal membrane was observed (Fig. 5A). Physical association of these two molecules was also detected only when rpMϕ were stimulated (Fig. 5B), and such an association was shown to

be induced rapidly (Fig. 5C). To explore the role of SIGNR1 in C. albicans recognition, we prepared sSIGNR1 and sDectin-1 tetramers, instead of the previously formed Dectin1-Ig-fusion proteins 9, 24. Thermal treatment of sSIGNR1 with Strep-Tactin at 37°C enhanced binding activity. This result may be due to the aggregation of SIGNR1 via its long neck domain (116 amino acids), which contains a heptad-repeat sequence, leading to increased ligand affinity and specificity, as previously reported 22, 25. Our study and several other reports indicate that Dectin-1 and TLR2 Pexidartinib mw recognize microbial components and induce inflammatory responses in either a cooperative 15, 29, 30 or independent manner 13, 14. In RAW-control cells, zymosan induced weak oxidative burst, but TLR ligand-depleted zymosan and PAM3CSK4 did not. By contrast, TLR ligand-depleted zymosan induced a significant

oxidative burst in RAW-SIGNR1 cells, and this response was not enhanced by PAM3CSK4. In addition, TLR2 blocking mAb had no effect on their oxidative burst in RAW-SIGNR1 cells. Based on these results, TLR2 is not largely involved in the oxidative burst response. SIGNR1 was shown to enhance the intracellular oxidative burst of rpMϕ in response to HK-C. albicans. Such an enhancement was due to the recognition of microbes via CRD, since RAW-SIGNR1 cells lacking CRD function were unable to elevate the response. In addition, binding/capture of microbes by SIGNR1 was demonstrated to be crucial for the enhanced oxidative response by the experiment titrating the number of microbes Inositol monophosphatase 1 during the culture. Dectin-1-specific inhibitors, such as laminarin and anti-Dectin-1 mAb, blocked the oxidative response in RAW-control cells, whereas these reagents by themselves showed no effect on the response in RAW-SIGNR1 cells. However, they were able to inhibit the response in cooperation with reagents to SIGNR1, as previously reported in the case of zymosan binding in rpMϕ 23. In addition, piceatannol, a Syk-specific inhibitor, totally blocked the response in not only the RAW-control but also RAW-SIGNR1 cells, demonstrating that the SIGNR1-dependent enhanced response relies on the Syk-mediated signaling pathway.

Among these proteins, apotransferrin selleck compound (apoTf) represents an endogenous immune modulator [9]. Numerous studies have provided evidence for clinical relevance of Tf in diseases that are associated with lower plasma transferring concentrations, as well as with Tf polymorphisms. These include pathologies with an inflammatory component such as renal ischaemia reperfusion injury, diabetes and diabetes-related complications, stroke, Alzheimer’s disease, cancer and atransferrinaemia (reviewed in [10]). In the case of type 1 diabetes, experimental reports support the presence of apoTf dysfunctions based

on reduced plasma levels in patients with long-lasting disease [11], but the significance of apoTf in the disease pathogenesis remains largely unknown. We report herein experimental results from pancreatic islet cells, animal models and sera from patients with different disease duration to define this issue more clearly. In particular, the data demonstrate that apoTf counteracts the cytokine-induced cell death of murine pancreatic islets and also prevents

learn more disease development in well-established type 1 diabetes models while modulating the cytokine profile at different diabetogenic stages. Further, we confirmed that patients with a new diagnosis of type 1 diabetes manifest significantly lower serum levels

of apoTf compared to patients with long-lasting disease and that Niclosamide levels correlate with glycaemic homeostasis. Recombinant human (rh) apoTf used for in-vitro studies was purchased from Calbiochem (Merck KGaA, Dramstadt, Germany), while human plasma-derived apoTf used for in-vivo experiments was derived by Kedrion (Barga, Italy) from fraction IV-1,4 of the Cohn plasma fractionation process. This fraction was dissolved in water and, after centrifugation, the supernatant was treated with a mixture of solvent/detergent as virus-inactivation step. The resulting solution was filtered, concentrated and diafiltered before chromatographic step. The obtained solution was loaded onto Q Sepharose XL column and Tf was eluted with a step gradient using 25 mM Tris/HCl buffer (pH 7·5) with 100 mM NaCl. The eluted solution was treated with an ion chelator to obtain pure apoTf which was then prefiltered using a 0·1 µm filter before using a 20-nm nanofilter as virus-removal step resulting in endotoxin contents consistently below 50 EU (endotoxin units)/ml. Rat insulinoma RINm5F cells were kindly donated by Dr Karsten Buschard (Bartholin Instituttet, Copenhagen, Denmark). Cells were grown in HEPES-buffered RPMI-1640 medium supplemented with 10% fetal calf serum (FCS).

Cerebellar involvement is variable, but can often be severe [6]. The reasons for this differential brain vulnerability to CAA remain obscure, but might relate

to varying efficiencies in perivascular drainage of parenchymally derived Aβ associated with Alzheimer-type pathology, given the observations that (in AD) the occipital cortex (where CAA is usually most severe) is often little affected by SP, and is always the least/last to be affected by tau pathology [7]. Because of the emphasis placed on the pathological staging systems for NFT [6], neuritic plaques [8] and Aβ [9], AD is largely thought of as a fairly ‘uniform’ and ‘predictable’ entity, passing through various hierarchical stages in the course of its evolution. However, subtle neuropsychological GDC-0068 price assessment reveals a clinically heterogeneous picture, especially in early stages of the disease where distinct memory, language, visual and frontal predominant syndromes can be seen [10]. There are also heterogeneities in the extent and distribution of the

main histopathological changes, particularly in relationship to CAA [11]. The present study sought to investigate a series of cases of AD with respect to the extent, distribution and morphological appearance of the neocortical deposition of Aβ as SP and CAA. Four histological phenotypes were discerned, and comparisons of their clinical, demographic and genetic features were performed. One hundred and thirty-four cases of AD were investigated. There were 67 men and 67

women. The age of onset ranged from 35 to 89 years (mean = 64.5 ± 11.0 Olaparib years), age of death ranged from 45 to 97 years (mean = 73.8 ± 10.2 years), and the duration of illness from 1 to 19 years (mean = 8.1 ± 3.0 years). Brain weight ranged from 760 g to 1456 g (mean = 1137 ± 154 g). The presence of previous family history or not had been documented in 120 patients, although this was definitely positive MRIP in only 14. Genetic analyses (other than APOE genotyping) had not been performed for any case. Pathological diagnoses were made by an experienced neuropathologist (D.M.A.M.), and were in accordance with recent National Institute on Ageing – Alzheimer’s Association guidelines for the neuropathological assessment of Alzheimer’s disease [12]. Based on investigations of representative areas of frontal, temporal and parietal cortical regions, all cases had Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) score of C for neuritic plaques [8] and were at Braak stage V or VI for neurofibrillary changes [7]. All cases were obtained from the Manchester Brain Bank through appropriate consenting procedures for the collection and use of the human brain tissues. The clinical phenotype, as defined by Stopford et al. [10], was available for 52 of the 134 cases.

It is assumed to exert multiple functions including packaging of pre-mRNA, regulation of alternative splicing, and nucleo-cytoplasmic transport of mRNA 7. HnRNP-A2 appears to be ubiquitously expressed, although the level of expression may greatly vary between different tissues. Interestingly,

hnRNP-A2 is overexpressed in RA synovial tissue, where it is detectable not only in the nucleus but also in the cytoplasm of macrophages and fibroblast-like synoviocytes 8. Autoantibodies RAD001 clinical trial to hnRNP-A2 (which are also known as anti-RA33 Ab) are present in approximately 30% of RA patients 9, but also in patients with systemic lupus erythematosus (SLE) and mixed connective tissue disease 9. Remarkably, however, epitope recognition was found to differ between the three disorders 10. Furthermore, also T cells from peripheral blood and synovial fluid of RA patients were found to

react to hnRNP-A2, in about 60% of the patients 8. Interestingly, autoimmunity to hnRNP-A2 has been observed in TNF-transgenic (Tg) mice 11, which develop arthritis spontaneously, and is a dominant immunological event in pristane-induced arthritis in rats 12. Altogether, the results suggest that this protein is an important and potentially pathogenic autoantigen in animal models of arthritis and in RA. Thus, it was the aim of the present study to characterize putative pathogenic T-cell epitopes of hnRNP-A2. To achieve this goal, we started with a comprehensive investigation of MHC binders among a library Pifithrin-�� cost 2-hydroxyphytanoyl-CoA lyase of 15-mer peptides spanning the entire human hnRNP-A2 protein. Peptides of this length can bind directly to MHC class II molecules on the cell surface

of APC where they can stimulate peptide-specific T cells. This method allows the analysis of all possible determinants regardless of whether the peptide is dominant or cryptic following natural processing. Then, to identify hnRNP-A2-specific T-cell epitopes in patients with RA, we used a sensitive IFN-γ ELISPOT assay, which detects in vivo-generated antigen-specific T cells in a low frequency range 13. The data obtained were confirmed in proliferation assays and reveal the presence of an immunodominant T-cell epitope associated to active RA. We synthesized 280 15-mer peptides overlapping by 13 or 14 amino acids and spanning the whole hnRNP-A2 sequence. These peptides were tested by competitive ELISA for binding to the RA-associated DR*0101 and DR*0401 molecules. The results obtained show that most epitopes binding to either DR*0101 or DR*0401 were localized in the N-terminal half (first 170 amino acids) of the hnRNP-A2 sequence (Fig. 1). Presence of an MHC epitope was revealed by 4–7 consecutive binding peptides. Frequently, many more consecutive peptides were binding, indicating overlapping epitopes. Six major determinants were found to bind to both DR*0101 and DR*0401: peptides no.

The question arose as to which mechanisms could explain the different kinetics between CD4+ cells and CD4+FOXP3+ cells. While the first decreased rapidly from the circulation during the inflammatory response following surgery, the Tregs remained stable in numbers and increased significantly in percentage of CD4+ see more T cells (Fig. 2A and B). For this purpose, we analyzed Ki67 expression in both total CD4+ and CD4+FOXP3+ population.

Ki67 is a protein important for cell division and is only expressed in proliferating cells. The percentage of Ki67+ cells was substantially higher in CD4+FOXP3+ cells compared to total CD4+ cell population at all time points. In all patients, CD4+ T cells showed a higher division rate 24 h after surgery (CD4+Ki67+ median before surgery and post-operative day one: 2.7 versus 7.8%, Fig. 3A, p<0.001). The same pattern could be seen in CD4+FOXP3+ cells (CD4+FOXP3+Ki67+ median before surgery and post-operative day one: 16 versus 40%, Fig. 3B, p<0.001). Notably, the FOXP3+ ratio in proliferating CD4+ T cells remained constant during the inflammatory response (median±SD before surgery, 24 and 48 h after surgery 18.2±4.2, 21.4±6.3 and 21.3±7.5, respectively). These findings indicate that proliferation increased in all CD4+ T cells 24 h after cardiac surgery, with highest proliferative activity in the

CD4+FOXP3+ cells. In human, FOXP3 expression does not always indicate regulatory capacity. True FOXP3 Tregs are anergic in vitro to TCR stimulation and suppress effector

T-cell proliferation. We determined the proliferative Regorafenib price Megestrol Acetate capacity of 5×103 effector T cells (Teffs) (CD4+CD25−) and 5×103 Tregs (CD4+CD25+CD127low) after TCR stimulation with anti-CD3 and compared these before and 24 h after surgery. The determined FOXP3+ Treg population was equally anergic 24 h after surgery as before surgery with approximately 3% proliferation compared to Teffs at the same time point (Fig. 4A). Next, we determined suppressive potential of the FOXP3+ Tregs at both time points, before and after surgery. Five thousand Teffs were co-cultured with or without equal numbers of Tregs from before and 24 h after surgery in the presence of plate bound anti-CD3 and 25 000 irradiated antigen-presenting cells from before surgery. Tregs from before surgery could clearly suppress proliferation of Teffs (55 and 54% suppression of Teffs obtained before and 24 h after surgery, respectively), while Tregs from 24 h after surgery showed diminished potential to suppress both T effector populations (28 and 17% suppression of Teffs obtained before and 24 h after surgery, respectively, Fig. 4B and Supporting Information Fig. 3). To further substantiate the functionality of Tregs before and after surgery, CFSE dilution assays were performed on PBMCs in co-culture with increasing ratio of Tregs.
