In this study, we observed the correlation among serum FGF23 and calcium, phosphorus and parathyroid hormone, and the correlation between FGF23 levels and cardiac structural changes in MHD patients.

Serum metabolomics analysis reveals metabolite profile and key biomarkers of idiopathic membranous nephropathy.

Background: Idiopathic membranous nephropathy (IMN) is an organ-specific autoimmune disease with multiple and complex pathogenic mechanisms. Currently, renal biopsy is considered the gold standard for diagnosing membranous nephropathy. However, there were limitations to the renal puncture biopsy, such as the relatively high cost, longer time consuming, and the risk of invasive procedures.

NFE2L3 as a Potential Functional Gene Regulating Immune Microenvironment in Human Kidney Cancer.

With the increasing incidence and mortality of renal cancer, it is pressing to find new biomarkers and drug targets for diagnosis and treatment. However, as one negative upstream regulator of p53, the prognostic and immunological role of NFE2L3 in renal cancer is still barely known. We investigated the expression, prognostic value, and relevant pathways of NFE2L3 using the datasets from public databases, including The Cancer Genome Atlas Program (TCGA), Genotype-Tissue Expression (GTEx), Cancer Cell Line Encyclopedia (CCLE), and UALCAN.

Human IL-17 and TNF-α Additively or Synergistically Regulate the Expression of Proinflammatory Genes, Coagulation-Related Genes, and Tight Junction Genes in Porcine Aortic Endothelial Cells.

Immune rejection is the major limitation for porcine xenograft survival in primate recipients. Proinflammatory cytokines play important roles in immune rejection and have been found to mediate the pathological effects in various clinical and experimental transplantation trials. IL-17 and TNF-α play critical pathological roles in immune disorders, such as psoriasis and rheumatoid arthritis.

Salivary microbiota analysis of patients with membranous nephropathy.

The oral microbiota are closely related to human health. Nonetheless, to the best of our knowledge, their relationship with membranous nephropathy (MN) remains unstudied. The saliva microbiota collected from 22 patients with MN and 15 healthy controls were analyzed by next‑generation sequencing, and bioinformatics analysis of the 16S ribosomal RNA gene was subsequently carried out.

The urinary exosomes derived from premature infants attenuate cisplatin-induced acute kidney injury in mice via microRNA-30a-5p/ mitogen-activated protein kinase 8 (MAPK8).

Acute kidney injury (AKI) is a susceptible factor for chronic kidney disease (CKD). There is still a lack of effective prevention methods in clinical practice. This study investigated the protective effect of the urinary exosomes from premature infants on cisplatin-induced acute kidney injury.

Dysregulated Microbiota-Driven Gasdermin D Activation Promotes Colitis Development by Mediating IL-18 Release.

The balance between gut microbiota and host is critical for maintaining host health. Although dysregulation of the gut microbiota triggers the development of various inflammatory diseases, including colitis, the molecular mechanism of microbiota-driven colitis development is largely unknown. Here, we found that gasdermin D (GSDMD) was activated during acute colitis.

Background: Systemic lupus erythematosus (SLE) and antineutrophil cytoplasmic antibody-associated vasculitis (AAV) are classically thought to cause renal impairment and small vessel vasculitis with different pathophysiologies. Their overlap constitutes a rare rheumatologic disease. To date, only dozens of such cases with biopsy-proven glomerulonephritis have been reported worldwide typically in women of childbearing age.

Generation of Systemic Lupus Erythematosus Patient-Derived Induced Pluripotent Stem Cells from Blood.

Systemic lupus erythematosus (SLE) is a chronic inflammatory autoimmune disease characterized by the production of multiple autoimmune antibodies and potentially involves any organ or tissue with a broad range of clinical manifestations. Conventional therapy still utilizes glucocorticoids and immunosuppressants. However, some patients show inadequate responses to glucocorticoids and immunosuppression, which may induce secondary immune dysfunction and severe infection as well as lead to an increased tumor risk.

Immunosuppressive and metabolic agents that influence allo- and xenograft survival by in vivo expansion of T regulatory cells.

The transplanted organs or cells survive if the recipient receives adequate long-term immunosuppressive therapy. Immunosuppressive therapy combined with cell-based strategies (eg, regulatory T cell [Treg]-based therapy) promotes graft survival. A combination of Treg-based therapy and minimal or no immunosuppressive drug therapy would have the potential to minimize the risks of the complications and side effects of these drugs.
