Abstract
T cells play an important role in the development of focal segmental glomerulosclerosis (FSGS). The mechanism underlying such T cell-based kidney disease, however, remains elusive. Here the authors report that activated CD8 T cells elicit renal inflammation and tissue injury via releasing miR-186-5p-enriched exosomes. Continuing the cohort study identifying the correlation of plasma level of miR-186-5p with proteinuria in FSGS patients, it is demonstrated that circulating miR-186-5p is mainly derived from activated CD8 T cell exosomes. Renal miR-186-5p, which is markedly increased in FSGS patients and mice with adriamycin-induced renal injury, is mainly delivered by CD8 T cell exosomes. Depleting miR-186-5p strongly attenuates adriamycin-induced mouse renal injury. Supporting the function of exosomal miR-186-5p as a key circulating pathogenic factor, intravenous injection of miR-186-5p or miR-186-5p-containing T cell exosomes results in mouse renal inflammation and tissue injury. Tracing the injected T cell exosomes shows their preferential distribution in mouse renal tubules, not glomerulus. Mechanistically, miR-186-5p directly activates renal tubular TLR7/8 signal and initiates tubular cell apoptosis. Mutating the TLR7-binding sequence on miR-186-5p or deleting mouse TLR7 largely abolishes renal tubular injuries induced by miR-186-5p or adriamycin. These findings reveal a causative role of exosomal miR-186-5p in T cell-mediated renal dysfunction.

Abstract
Immunosenescence is a natural ageing phenomenon with alterations in innate and especially adaptive immunity and contributes to reduced antimicrobial defence and chronic low‐grade inflammation. This is mostly reflected by an increase in organ‐directed and/or circulating reactive and cytolytic terminally differentiated T cells that have lost their expression of the costimulatory receptor CD28. Apart from being induced by a genetic predisposition, ageing or viral infections (particularly cytomegalovirus infection), immunosenescence is accelerated in many inflammatory diseases and uraemia. This translates into an enhancement of vascular inflammation and cardiovascular disease varying from endothelial dysfunction to plaque rupture. Emerging data point to a mechanistic role of CD28null T cells in glomerulonephritis, where they initiate and propagate local inflammation in concordance with dendritic cells and macrophages. They are suitably equipped to escape immunological dampening by the absence of homing to lymph nodes, anti‐apoptotic properties and resistance to suppression by regulatory T cells. Early accumulation of senescent CD28null T cells precedes glomerular or vascular injury, and targeting these cells could open avenues for early treatment interventions that aim at abrogating a detrimental vicious cycle.

Abstract
Lupus nephritis is a severe organ manifestation in systemic lupus erythematosus leading to kidney failure in a subset of patients. In lupus-prone mice, controlled infection with Plasmodium parasites protects against the progression of autoimmune pathology including lethal glomerulonephritis. Here, we demonstrate that parasite-induced protection was not due to a systemic effect of infection on autoimmunity as previously assumed, but rather to specific alterations in immune cell infiltrates into kidneys and renal draining lymph nodes. Infection of lupus-prone mice with a Plasmodium parasite did not reduce the levels or specificities of autoreactive antibodies, vasculitis, immune complex-induced innate activation, or hypoxia. Instead, infection uniquely reduced kidney-infiltrating CCL17-producing bone marrow-derived type 2 inflammatory dendritic cells (iDC2s). Bone marrow reconstitution experiments revealed that infection with Plasmodium caused alterations in bone marrow cells that hindered the ability of DC2s to infiltrate the kidneys. The essential role for CCL17 in lupus nephritis was confirmed by in vivo depletion with a blocking antibody, which reduced kidney pathology and immune infiltrates, while bypassing the need for parasitic infection. Therefore, infiltration into the kidneys of iDC2s, with the potential to prime local adaptive responses, is an essential regulated event in the transition from manageable glomerulonephritis to lethal tubular injury.

Abstract
Alterations to the programmed cell death protein-1 (PD-1) pathway were previously shown to be involved in a poorer prognosis for patients with proliferative glomerulonephritis (PGN). Here, we investigated the association between several infectious agents and the expression of PD-1 and its ligand (PD-L1) on T and B lymphocytes in patients with PGN and nonproliferative glomerulonephritis (NPGN). A cohort of 45 newly-diagnosed patients (23 with PGN and 22 with NPGN) and 20 healthy volunteers was enrolled. The percentage of peripheral blood mononuclear cells expressing PD-1 and PD-L1 antigens was determined by flow cytometry. We found PD-1 and PD-L1 expression on T and B lymphocytes was higher in PGN patients than in NPGN patients and controls. We also found that reactivation of the Epstein-Barr virus (EBV) correlated with the expression of PD-1/PD-L1 antigens in patients with PGN. Further receiver operating characteristic analysis indicated that PD-1 expression could distinguish EBV-positive PGN patients from those with NPGN or healthy controls. The use of PD-1 expression as a non-invasive marker of PGN should be further investigated.

Abstract
The mechanism by which glucocorticoids alleviate renal inflammatory disorders remains incompletely understood. Here, we report that the efficacy of glucocorticoids in ameliorating FSGS depends on the capacity to expand myeloid-derived suppressor cells (MDSCs). After glucocorticoid treatment, the frequency of CD11b(+)HLA-DR(-)CD14(-)CD15(+) MDSCs in peripheral blood rapidly increased in patients with glucocorticoid-sensitive FSGS but remained unchanged in patients with glucocorticoid-resistant FSGS. The frequency of CD11b(+)Gr-1(+) MDSCs in mouse peripheral blood, bone marrow, spleen, kidney-draining lymph nodes (KDLNs), and kidney also increased after glucocorticoid treatment. The induced MDSCs from glucocorticoid-treated mice strongly suppressed T cells, dendritic cells, and macrophages but induced regulatory T cells in spleen, KDLNs, and kidney. Moreover, glucocorticoid treatment suppressed doxorubicin-induced T cell proliferation, dendritic cell and macrophage infiltration, and proinflammatory cytokine production, whereas this protective effect was largely abolished by depleting MDSCs using anti-Gr-1 antibody. Finally, the adoptive transfer of induced MDSCs into the doxorubicin-treated mice not only confirmed the protective role of MDSCs in doxorubicin-induced renal injury but also showed that the transferred MDSCs rapidly migrated into the lymphocyte-accumulating organs, such as the spleen and KDLNs, where they suppressed T cell proliferation. Taken together, these results demonstrate that glucocorticoid treatment ameliorates FSGS by expanding functional MDSCs and that this rapid elevation of MDSCs in peripheral blood may serve as an indicator for predicting the efficacy of glucocorticoid treatment.

Abstract
Background Interactions between dendritic cells (DCs) and T cells play a critical role in the development of glomerulonephritis, which is a common cause of chronic kidney disease. DC-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN), an immune-regulating molecule of the C-type lectin family, is mainly expressed on DCs and mediates DC adhesion and migration, inflammation, activation of primary T cells. DC-SIGN triggers immune responses and is involved in the immune escape of pathogens and tumours. In addition, ligation of DC-SIGN on DCs actively primes DCs to induce Tregs. Under certain conditions, DC-SIGN signalling may result in inhibition of DC maturation, by promoting regulatory T cell (Treg) function and affecting Th1/Th2 bias. Methods A rat model of nephrotoxic nephritis was used to investigate the therapeutic effects of an anti-lectin-epidermal growth factor (EGF) antibody on glomerulonephritis. DCs were induced by human peripheral blood mononuclear cells in vitro. The expression of DC surface antigens were detected using flow cytometry; the levels of cytokines were detected by ELISA and qPCR, respectively; the capability of DCs to stimulate T cell proliferation was examined by mixed lymphocyte reaction; PsL-EGFmAb targeting to DC-SIGN on DCs was identified by immunoprecipitation. Results Anti-Lectin-EGF antibody significantly reduced global crescent formation, tubulointerstitial injury and improved renal function impairment through inhibiting DC maturation and modulating Foxp3 expression and the Th1/Th2 cytokine balance in kidney. Binding of anti-Lectin-EGF antibody to DC-SIGN on human DCs inhibited DC maturation, increased IL-10 production from DCs and enhanced CD4+CD25+ Treg functions. Conclusions Our results suggest that treatment with anti-Lectin-EGF antibody modulates DCs to suppressive DCs and enhances Treg functions, contributing to the attenuation of renal injury in a rat model of nephrotoxic nephritis.

Abstract
AIMS The role of kidney infiltrating T cells in the pathology of lupus nephritis is unclear. This study was undertaken to investigate whether CD4+ T cell responses to a surrogate mesangial antigen can initiate glomerulonephritis. METHODS Ovalbumin (OVA) was deposited in the glomerular mesangium of C57BL/6 (B6) mice using anti-α8-integrin immunoliposomes (α8ILs). This was followed by injection of activated OVA-reactive CD4+ transgenic OT2 T cells. Trafficking of antigen-specific OT2 T cells to kidneys and lymph nodes was studied by flow cytometry. Glomerular pathology and immune cell infiltration was characterized by immunostaining. Role of CCR2 deficiency on T cell-mediated glomerulonephritis was investigated using B6.ccr2(-/-) mice. RESULTS α8ILs delivered OVA specifically to the renal glomeruli. Adoptively transferred OT2 T cells preferentially accumulated in renal lymph nodes and in the renal cortex. Kidneys showed glomerular inflammation with recruitment of endogenous T cells, dendritic cells and macrophages. T cell-mediated inflammation induced mesangial cell activation and an increase in glomerular MCP1 and fibronectin. The formation of inflammatory foci was driven by Ly6C monocytes and was CCR2 dependent. CONCLUSIONS The findings from this study show that T cells reactive with antigens in the mesangium are sufficient to initiate glomerular pathology. Antigen-specific CD4 T cells act by inducing glomerular MCP1 production which mediates recruitment of inflammatory monocytes resulting in glomerulonephritis. Thus, down-modulation of T cell responses within the kidneys of lupus patients will be a beneficial therapeutic approach.

Abstract
Genetically modified immune responses to infections and self-antigens initiate most forms of GN by generating pathogen- and danger-associated molecular patterns that stimulate Toll-like receptors and complement. These innate immune responses activate circulating monocytes and resident glomerular cells to release inflammatory mediators and initiate adaptive, antigen-specific immune responses that collectively damage glomerular structures. CD4 T cells are needed for B cell-driven antibody production that leads to immune complex formation in glomeruli, complement activation, and injury induced by both circulating inflammatory and resident glomerular effector cells. Th17 cells can also induce glomerular injury directly. In this review, information derived from studies in vitro, well characterized experimental models, and humans summarize and update likely pathogenic mechanisms involved in human diseases presenting as nephritis (postinfectious GN, IgA nephropathy, antiglomerular basement membrane and antineutrophil cytoplasmic antibody-mediated crescentic GN, lupus nephritis, type I membranoproliferative GN), and nephrotic syndrome (minimal change/FSGS, membranous nephropathy, and C3 glomerulopathies). Advances in understanding the immunopathogenesis of each of these entities offer many opportunities for future therapeutic interventions.
