In addition, there may be subsets of CD4 memory cells that are not biased toward any lineage,

and so display the highest degree of lineage potential following reactivation with antigen. In the case of such non-committed cells, the prediction would be that lineage-associated transcription factor and/or effector genes (i.e Tbx21/Tbet, Gata3, Rorg, Bcl6, IFNg, IL4, etc.) have not yet acquired epigenetic CP-673451 cell line modifications consistent with expression of these genes that would skew their response toward any particular lineage. In depth gene expression and epigenetic analysis of memory subsets will be useful in determining whether ‘Th uncommitted’ memory CD4 T cells contribute significantly to the pool of memory T cells. Further, analysis of on-off-on gene regulation for genes such as CD62L, CCR7 and Bcl2 in memory cells will be useful for understanding factors that govern homing and survival during homeostasis find more in the absence of their antigen, and possibly be predictive of the fate of memory cells following re-encounter with antigen. It is essential to understand how antigen-specific CD4 memory T cells behave in response to repeated exposure to pathogen, or throughout the course of vaccination, where priming and repeated boosting to antigen, results in reactivation of memory cells. Determining whether memory CD4 T cells ‘remember’ and

efficiently recall lineage-specific gene expression programmes that were acquired during their progenitors at the effector stage will provide an important framework for predicting the capacity of memory CD4 T-cell subsets to provide cellular immune responses and provide help for humoral immune responses

upon boosting or challenge with pathogen. A shared feature of CD4 and CD8 T-cell memory differentiation is HSP90 that the strength and duration of TCR signalling determines the function and phenotype of the cells. At the extreme end of the TCR strength/duration of the signal spectrum are cells differentiated during chronic viral infections. Therefore, additional insights into the mechanism for differentiation of functional memory T cells may be gained from interrogating the mechanism for development of non-functional memory cells during conditions of antigen persistence. Failure to control viral infection results in a diminished ability of antigen-specific CD8 T cells to rapidly up-regulate cytokine expression and to kill antigen-presenting cells, often regarded as T-cell exhaustion.[52, 53] It is now well accepted that these functionally impaired exhausted T cells can be rejuvenated through manipulation of their inhibitory receptor signalling, and therapeutic strategies that target these inhibitory mechanisms play an important role in clearance of chronic viral infections such as HIV or hepatitis C virus, as well as control of several types of cancer.

“Monocytes, key components of the immune system, are a heterogeneous population comprised of classical monocytes (CD16-) and non-classical monocytes (CD16+). Monocytes are short lived and undergo spontaneous apoptosis, unless stimulated. Dysregulation of monocyte numbers contribute to the pathophysiology

of inflammatory diseases, yet the contribution of each subset remains poorly characterized. Protein Kinase C (PKC) family members are central AZD3965 to monocyte biology, however, their role in regulating lifespan and immune function of CD16- and CD16+ monocytes have not been studied. Here, we evaluated the contribution of PKCδ and PKCε in the lifespan and immune response of both monocyte subsets. We showed that CD16+ monocytes are more susceptible to spontaneous apoptosis due to the increased caspase-3, -8 and -9 activities accompanied by higher kinase activity of PKCδ. Silencing of PKCδ reduced apoptosis in both CD16+ and CD16- monocytes. CD16+ monocytes express significantly higher levels of PKCε and produce more TNF-α in CD16+ as compared to CD16- monocytes. Silencing of PKCε affected the survival and TNF-α production. These findings demonstrate a complex network with

similar topography, yet unique regulatory characteristics controlling lifespan and immune response in each monocyte subset, helping define subset-specific coordination programs controlling monocyte function. This article is protected by copyright. All rights reserved. “
“Phospholipase Cε (PLCε) is an effector CH5424802 research buy of Ras and Rap small GTPases. We showed previously using PLCε-deficient mice that PLCε plays a critical role in activation PtdIns(3,4)P2 of cytokine production in non-immune skin cells in a variety of inflammatory reactions. For further investigation of its role in inflammation, we created transgenic mice overexpressing PLCε in epidermal keratinocytes. The resulting transgenic mice spontaneously developed skin inflammation as characterized by formation of adherent silvery scales, excessive growth of keratinocytes, and aberrant infiltration of immune cells such as T cells and DC. Development of the skin symptoms correlated well with increased expression of factors implicated

in human inflammatory skin diseases, such as IL-23, in keratinocytes, and with the accumulation of CD4+ T cells producing IL-22, a potent inducer of keratinocyte proliferation. Intradermal injection of a blocking antibody against IL-23 as well as treatment with the immunosuppressant FK506 reversed these skin phenotypes, which was accompanied by suppression of the IL-22-producing T-cell infiltration. These results reveal a crucial role of PLCε in the development of skin inflammation and suggest a mechanism in which PLCε induces the production of cytokines including IL-23 from keratinocytes, leading to the activation of IL-22-producing T cells. The epidermis consists of tightly packed layers of keratinocytes and provides a first line of defense against pathogens and insults 1.

The tissue fragments were collected with 4-mm punch and fixed in formalin 10%, pH 7·2, and processed by the usual techniques for optical microscopy. At 4th and 8th weeks PI, biopsies from the hind footpads were collected, soaked in OCT medium (Easy Path, Brazil), and immediately frozen in liquid nitrogen. The fragments were stored in freezer at −80°C. Sections from skin were prepared using a cryostat microtome (Leica

Microsystems, Wetzlar, Germany), and fixed in acetone–chloroform (1 : 1) for 10 min at room temperature. After washing in PBS (for 10 min), the endogenous peroxidase and nonspecific binding were blocked with a solution of hydrogen peroxidase 0·3% (10 min) and skimmed milk 6% (1 h),

respectively. Fragments of Selleck Saracatinib skin were Ibrutinib purchase incubated overnight with monoclonal antibodies rat anti-mouse CD207 (BD Bioscience, San Diego, CA, USA) at 1 : 100, CD4 and CD8α (BD Pharmingen, San Diego, CA, USA) at 1 : 160 and 1 : 40, respectively, and hamster anti-mouse CD11c (BD Pharmingen) at 1 : 10 dilution in PBS plus 1% BSA. The biotinylated secondary antibody goat anti-rat immunoglobulin (BD Pharmingen), at 1 : 50 dilution, incubated for 1 h at 37°C was used for CD4, CD8, and CD207, and mouse anti-hamster IgG cocktail (BD Pharmingen) at 1 : 50 dilution for CD11c. The sections were incubated with streptavidin–HRP (Dako, Carpinteria, CA, USA) for 45 min at 37°C. Afterwards, the sections were incubated with diaminobenzidine solution from Liquid DAB+Substrate Chromogen System (Dako) for 5–10 min. The sections were counterstained with Harris Hematoxylin, and the slides were mounted using cover slides and

resin. For quantitative analysis, ten different fields of each section were photographed, and the cell numbers were evaluated with a Carl Zeiss microscope coupled to a computer using the axion vision 5·0 software (Axion Vision, Carl Zeiss Microscopy GmbH, Munich, Germany). The cellular densities were expressed by cells per square millimetre. The paraffin-embedded skin sections were dewaxed and rehydrated, and the antigen retrieval also was performed by steaming in 10 mm citric acid solution (pH 6·0) for 30 min at 95°C in a water bath. Endogenous peroxidase activity was blocked with 3% hydrogen peroxide and nonspecific interactions with a solution of 6% powdered skimmed milk solution. The reaction was developed using, as a primary antibody, rabbit anti-NOS2 polyclonal antibody (Santa Cruz Biotechnology, Santa Cruz, CA, USA) at 1 : 1000 dilution in PBS plus 1% BSA and, as a detection system, NovoLink Max Polymer (Novocastra, Newcastle Upon Tyne, United Kingdom). The sections were counterstained with Harris Hematoxylin, and the slides were mounted using cover slides and resin.

In conclusion, the results of the present study suggested that upregulation of IL-21 and IL-10 and downregulation Selleck BMS907351 of IL-4

in periodontitis tissues may be collectively involved in the increased levels of salivary IgA in chronic periodontitis subjects. Since only cytokine profiles and salivary IgA level were evaluated and, no characterization of naïve B cell switch in the periodontal lesions was performed, these preliminary findings are still not enough to definitely define the mechanisms of Ig isotype switching on chronic periodontitis. However, our results may provide new insights into the possible role of Th-secreted cytokines in driving humoral immune response on periodontal tissue breakdown. The authors thank Ms Jeruza P.

“Although Fasudil has shown therapeutic potential in EAE mice, the mechanism of action are still not fully understood. Here, we examined the immunomodulatory effect of Fasudil on encephalitogenic mononuclear cells (MNCs), and tested the therapeutic

potential of Fasudil-treated MNCs in active EAE. Fasudil inhibited expression of CCL20 on T cells and migration of T cells, decreased CD4+IFN-γ+ and CD4+IL-17+ T cells, but increased CD4+IL-10+ and CD4+TGF-β+ Adenosine T cells. Fasudil reduced expression of CD16/32 and IL-12, while elevating expression of CD206, CD23, and IL-10. Fasudil also decreased levels of iNOS/NO, enhanced levels of Arg-1, and inhibited the TLR-4/NF-κB signaling and TNF-α, shifting M1 macrophage to M2 phenotype. These modulatory effects of Fasudil on T cells and macrophages were not altered by adding autoantigen MOG35–55 to the culture, i.e., autoantigen-independent. Further, we observed that, in vitro, Fasudil inhibited the capacity of encephalitogenic MNCs to adoptively transfer EAE and reduced TLR-4/p-NF-κB/p65 and inflammatory cytokines in spinal cords. Importantly, Fasudil-treated encephalitogenic MNCs exhibited therapeutic potential when injected into actively induced EAE mice. Together, our results not only provide evidence that Fasudil mediates the polarization of macrophages and the regulation of T cells, but also reveal a novel strategy for cell therapy in MS.

5 mL SCM, 4 μg/mL polybrene (Sigma), and fresh cytokines into six well plates treated with human fibronectin (Sigma) for 4 h at room temperature. Cultures were transduced by spinoculation at 1800 rpms and 37°C for 2 h. Cultures were incubated at 37°C for 24 h and then retransduced with fresh virus supernatant for another 24 h. Cultures were collected, washed twice in PBS, resuspended in PBS, and retinal orbitally injected into irradiated C57BL/6

mice. C57BL/6 mice were irradiated with one lethal dose of 950 rads 24 h prior to reconstitution. PBMCs were collected by submandular bleeds into heparin (Sigma) treated tubes. RBCs were precipitated with 20 mg/mL Dextran T500 (Amersham Pharmacia Biotech, Piscataway, NJ, USA) in PBS for 30 min at 37°C. Supernatants were collected, Selleck PD0325901 spun, and remaining RBC were lysed with ACK. Cells were washed twice with staining buffer (PBS + 0.5% BSA) before staining with CD45.1-PE (eBioscience A20, San Diego, CA, USA) and CD45.2- PerCP-Cy5.5

(eBioscience 104) for donor reconstitution, CD4-PerCP-Cy5 (BD Pharmingen RM-4, San Jose, CA, USA) and CD8-PE (eBioscience 53–6.7) for T lymphocytes, B220-PE-Cy5 (eBioscience RA3–6B2) or B220-PerCP-Cy5.5 (eBioscience RA3–6B2) and CD19-PE (eBioscience eBioD3) for BMS-354825 datasheet B lymphocytes, or CD11b-PerCP-Cy5.5 (eBioscience M1/70) and Gr-1-PE (BD Pharmingen RB6.8C5) for myeloid cells. BM cells were flushed from tibia and femur, treated with ACK to lyse RBCs, and filtered. Mature BM cells were Etofibrate lineage depleted with a standard cocktail of rat antibodies: CD2, CD3, CD5, CD8, CD11b, Ly-6G, TER119, CD45R, and CD19. Labeled cells were removed by two consecutive depletions with Dynabeads sheep antirat IgG (Invitrogen Dynal). Remaining progenitor cells were incubated with Sca-1-PE (BD Pharmingen D7) and c-Kit-AF647, and DAPI for viability. Cell data was collected with BD FACSAria or BD FACScanto II and data analysis was done with BD FlowJo software. Monoclonal antibodies raised against CD2 (Rm2.2), CD3 (KT3–1.1), CD5 (53–7.3), CD8 (53–6.7), CD11b (M1/70), Ly-6G (RB6–8C5), TER119, CD45R

We also tested the 3C3-C-20 mAb graciously provided by Ronald Scheule of Genzyme Inc. (Boston, MA, USA). 3C3-C-20 blocked the antiviral activity of full length SP-D (i.e., HA inhibiting concentration of SP-D

dodecamers was 37 ± 4 ng/ml, whereas no inhibition was seen up to 1 μg/ml after pre-incubation of SP-D with 3C3-C-20; n = 4; P < 0.001). As in the case of mAb 246-02, the binding of 3C3-C-20 was greatly diminished by the RAK insertion and restored to baseline by the combined RAK+R343V mutations (Table 2). ITF2357 manufacturer These findings suggest that the combined mutant restores structural features recognized by these mAb that are lost in the RAK insertion mutant. Table 3 shows the HA inhibitory activity of the bovine serum collectins in comparison with that of the wild-type human SP-D NCRD. CL-43, CL-46 and conglutinin NCRD all had measurable HA inhibitory activity, while hSP-D-NCRD did not at least up to a concentration of 50 μg/ml. We also tested HA inhibitory activity by https://www.selleckchem.com/screening/anti-infection-compound-library.html the NCRD after cross-linking of the various collectins with mAb. We have previously reported that the 246-04 and 246-08 mAb increase HA activity of hSP-D-NCRD [31]; however, in the current study, no enhancement of activity of conglutinin was found (Table 3). This was particularly

surprising because it expressed the 246-08 epitope very strongly in the solid-phase binding assay. In contrast, mAb 246-08 increased the activity of the CL-46 NCRD. We now show that the 6B2 mAb also increases HA inhibitory activity of hSP-D-NCRD (Table 3). The 6B2 mAb also strongly increased HA inhibitory activity of CL-46 and CL-43 NCRD (consistent the data in Table 2 showing binding of this mAb to these proteins). As shown in Table 3, cross-linking of the mutant NCRD derived from SP-D with the enhancing Carnitine palmitoyltransferase II mAb 246-04,

246-08 or 6B2 increased their HA inhibitory activity as well. The 246-08 and 6B2 mAb had stronger enhancing activity than 246-04 in these assays. Despite the genetic and structural relationships between SP-D and bovine serum collectins, there are significant differences in ligand recognition and in key residues surrounding the primary carbohydrate binding site. When compared to trimeric subunits of SP-D, CL-43 trimers show greater interactions with mannan and IAV [16]. In addition, conglutinin dodecamers have distinct monosaccharide recognition properties and greater antiviral activity than SP-D dodecamers [15] and the NCRD of conglutinin has been reported to have antiviral activity while that of SP-D does not [36, 37]. We now directly compare NCRD preparations of CL-43, conglutinin and CL-46 and find that all of them have intrinsically greater antiviral activity than the human SP-D. The viral neutralizing and HA inhibiting activities of the CL-46 NCRD have not been previously reported on and appear as strong, or stronger than, the other bovine serum collectins.

Renovascular hypertension (RVHT) is systemic hypertension due to haemodynamically significant RAS of the main renal artery or its proximal branches.1 From a haemodynamic point of view, a stenosis is significant when there is a demonstrable pressure gradient. The pressure drop beyond the stenosis triggers intrarenal

adaptive mechanisms leading to renal ischaemia and hypertension.2 At least a 50% narrowing is necessary to produce such a pressure gradient, as shown by a study combining three-dimensional MRA and direct measurements across a stenotic lesion.3 Therefore, despite lack of consensus, most authors use a reduction in luminal diameter of 50% as a cut-off point, to define the presence of haemodynamically significant RAS.4 Atherosclerosis accounts for 70–90% of cases of RAS and usually involves the ostium and proximal third of the main AP24534 solubility dmso renal artery.5,6 FMD is a collection of vascular diseases that affects either intima, media or adventitia and is responsible for 10–30% of cases of RAS.5,7 The prevalence of RAS in an unselected hypertensive population varies between 1% and 5%.8 This increases to 20–40% in patients who exhibit specific clinical symptoms AZD5363 or signs of RVHT.6 The IA-DSA is regarded as the gold standard for diagnosis of RAS. However, it is invasive, does not establish the functional nature of the stenotic lesion and is subject to substantial inter-observer

variations.9,10 Conventional IA-DSA is hazardous, especially in those patients most likely to be studied, where co-existing aortic disease may result in athero-embolic complications and therefore clinicians will continue to rely on non-invasive methods as initial diagnostic steps.11 These guidelines are an attempt to provide an overview of diagnostic accuracy and reproducibility of three contemporary imaging modalities: duplex ultrasound, CTA and contrast-enhanced magnetic resonance

angiography (CE-MRA) for the detection of RAS in patients with clinically suspected RVHT. Functional tests of the renin-angiotensin system, including Terminal deoxynucleotidyl transferase captopril renography, are not included in these guidelines. They are not recommended in elderly atherosclerotic patients because hypertension in these patients is not renin-dependent and the results do not reliably predict the course of hypertension after revascularization.5 Databases searched: The terms used to define arterosclerotic renovascular disease were ‘renal artery obstruction’ (as a MeSH term and text word) and ‘renal artery stenosis’, ‘renovascular disease$’ and ‘renal artery occlusion$’ as text words were combined with relevant MeSH terms and text words for diagnosis. The search was performed in Medline (1950 to April 2009). The Cochrane Renal Group Trials Register was also searched for trials not indexed in Medline. Date of searches: 2 April 2009.

DAPI (Invitrogen) was used at 300 nM to identify cellular nuclei. Sections were mounted by using Fluorogel (Electron Microscopy Services). this website All sections were imaged using either a Nikon Eclipse 80i microscope or an Olympus BX-51

microscope. Three TBI animals were analyzed and at least five sections per animal were analyzed. For gene expression profiling of macrophages from YARG mice, Arg1+ (YFP+ CD45hi CD11b+ Ly6G− SYTOX Blue−) and Arg1− macrophages (YFP− CD45hi CD11b+ Ly6G− SYTOX Blue−) were isolated by flow cytometry from ipsilateral brain hemispheres at day 1 following TBI (n = 4 for each cell sample). Monocytes (CD11b+ F4/80+) from peripheral blood were also collected. Sorted cells were immediately lysed in denaturation buffer and frozen. RNA was isolated by using an RNAqueous Micro kit (Ambion). Further sample preparation, labeling, and array hybridizations were performed according to standard protocols from the UCSF Shared Microarray Core Facilities and Agilent Technologies. RNA quality was assessed using a Pico Chip on an Agilent 2100 Bioanalyzer (Agilent Technologies), and RNA was amplified by use of a whole transcriptome

amplification kit (Sigma-Aldrich). selleck Subsequent Cy3-CTP labeling was performed by using a NimbleGen one-color labeling kit (Roche-NimbleGen, Inc.). The quality of the amplified products was assessed by using an Agilent 2100 Bioanalyzer and Nanodrop ND-8000 (Nanodrop Technologies, Inc.). Tau-protein kinase The products were hybridized to Agilent whole mouse genome 4×44K microarrays according to the manufacturer’s protocol. Arrays were scanned with an Agilent microarray scanner, and raw signal intensities were extracted with Feature Extraction v10.5 software. Data were normalized by using the quantile normalization method [54]. No background subtraction was performed,

and the median feature pixel intensity was used as the raw signal before normalization. A one-way ANOVA linear model was fitted to the comparison to estimate the false discovery rate for each gene for the comparison of interest, and genes with a false discovery rate < 0.05 were considered significant. Scatter plots compared averaged log2 gene expression from each group. PCA was performed using the top 15% of genes exhibiting the most variance across all samples, using the PopulationDistances module of GenePattern (PMID: 16642009). For heatmaps, data were log2 transformed and median centered across genes. Replicates were hierarchically clustered (PMID: 16939791). Heatmaps of genes selected from the top 15% most variable genes that exhibited interesting pairwise comparisons were visualized using Java Treeview (http://sourceforge.net/projects/jtreeview/files/) (PMID: 15180930). Meta-analysis of transcriptional responses of brain wound macrophages to BMDMs stimulated by either IFN-γ or IL-4 was performed using previously published tables [38].

Urine levels of soluble CXCL16 are increased in patients with lupus nephritis or renal allograft rejection.53,54 Macrophage migration inhibitory factor (MIF) is a molecule that is produced at sites BMS-907351 nmr of inflammation and inhibits further macrophage migration in response to chemokines, thereby allowing macrophages to accumulate at the inflammatory site. MIF can also enhance the activity of macrophages and T cells at sites of injury. Increasing levels of MIF in urine correlate with kidney leukocyte accumulation and the severity of renal damage in proliferative forms of glomerulonephritis.55 In addition, elevated

MIF levels in urine can predict episodes of acute renal allograft rejection and discriminate from cyclosporine nephrotoxicity.56 There are also other pro-inflammatory mediators that can indentify inflammation in the injured kidney. Vascular cell adhesion molecules-1 (VCAM-1) is expressed by renal vessels and some kidney cells during renal inflammation and facilitates transendothelial leukocyte migration. Some of this VCAM-1 is enzymatically cleaved VX-770 ic50 and excreted into the urine. Urine levels of soluble VCAM-1 are

elevated during active periods of anti-nuclear cytoplasmic antibody vasculitis and lupus nephritis,53,57 and are useful for determining the severity and type of renal allograft rejection.58 Interleukin-18 (IL-18) is a pro-inflammatory cytokine that is produced by leukocytes, vessels and kidney tubules. During acute renal injury, there is a substantial increase in IL-18 production by tubules. Elevated urine levels of IL-18 are a relatively sensitive and specific marker of acute tubular necrosis (ATN) and delayed graft function in the post ischaemic kidney.59 Urine levels also correlate with disease activity in idiopathic

nephritic syndrome.60 Tumour necrosis factor receptor-1 (TNFR1) is one of the major receptors for the pro-inflammatory cytokine TNF-α, which is expressed on infiltrating leukocytes and some Resveratrol resident kidney cells during renal inflammation. The soluble form of TNFR1 is more stable and easier to detect in serum and urine than TNF-α and it can serve as a surrogate marker of TNF-α activity in kidney disease. Serum and urine levels of soluble TNFR1 are increased during acute and chronic renal inflammation and correlate with the progression of acute renal failure, lupus nephritis and diabetic nephropathy.50,53,61 Another recent inclusion to this family of biomarkers is soluble human leukocyte antigen-DR. Urine levels of soluble human leukocyte antigen-DR are a sensitive and highly specific marker of acute renal allograft rejection, which can be detected up to 5 days before the clinical signs of acute cellular or vascular rejection are evident.62 The development of renal fibrosis is dependent on excessive production of profibrotic growth factors and extracellular matrix, which can be detected in urine by ELISA.

Among 1976 pre-dialyzed HIV subjects, 661 were prospectively followed-up for 4 years to determine incidence of composite outcomes, including all-cause mortality, cardiovascular disease and

a decline over 25% from baseline in eGFR. Four risk categories (0 to 3) were constructed using the combination of 5 stages of eGFR and 3 grades of albuminuria. The cumulative incidence of the outcomes was analyzed with Kaplan-Meier method, and hazard risk (HR) of risk categories for the outcome incidence was calculated using multivariable proportional hazards regression analysis, adjusted for some known risk factors. Results: The frequency of each CKD category was shown EPZ015666 nmr in Figure 1. The prevalence of HIV infection was 0.024% in the chronic HD patients. The Kaplan-Meier estimates were significantly increased over time in the risk categories 2 and 3, compared with the risk categories 0 and 1 (Figure 2). The HR of risk categories 2 and 3 was 2-fold greater (HR = 2.00; its 95% confidence interval, 1.08–3.57; P = 0.0277), as compared to risk categories 0 and 1. Conclusion: The new CKD classification may facilitate targeting of high-risk CKD in the HIV-infected population as well as in the general population. WU SUNNY1, MASSON PHILIP1,

We aimed to summarise how CKD affects cognitive function. Methods: We searched databases Pexidartinib purchase (Jan 2014) for studies measuring cognitive function using validated neuropsychological tools in participants with CKD. We extracted measures of cognition and synthesised results for cognitive domains stratified by glomerular filtration rate (GFR) using random effects, expressed as

standardized mean differences (SMD) with 95% confidence intervals (CI). Depending on the study design, we assessed quality using either the Newcastle-Ottawa scale or the Cochrane risk of bias tool. Results: In interim Dichloromethane dehalogenase analyses, we included 28 studies (112,714 participants): 17 cross-sectional studies (37,889 participants), 10 cohort studies (46,441 participants) and 1 randomised control trial (28,384 participants). Studies measured cognition using 43 different tools. Cognitive domains were measured with varying frequencies: global cognition (23 studies), executive function (14 studies), attention (14 studies), processing speed (14 studies), memory (13 studies), language (9 studies), visuo-spatial perception (5 studies) and intelligence (2 studies). No study measured psychomotor function. Overall, methodological quality of cohort studies was better than cross-sectional studies where analyses were unadjusted for potential confounders, making meaningful comparison challenging. Compared to people with GFR >60 ml/min/1.
