Complement expression profiles in human glomerular mesangial cells, endothelial cells, podocytes and proximal tubular epithelial cells

BackgroundLocal expression of complement components in the kidney has been reported sporadically in both diseased and normal kidneys. This study aimed to comprehensively characterize the expression of complement components in human glomerular mesangial…

Risk prediction of PLA2R-Ab-negative membranous nephropathy: an interpretable multicenter machine learning model

BackgroundApproximately 10%–30% patients with biopsy-proven membranous nephropathy (MN) are seronegative for anti-phospholipase A2 receptor antibody (PLA2R-Ab). Only ~5% are truly non-PLA2R MN and are associated with alternative antigens (e.g., THSD7A)…

Folate-modified liposomal celastrol for rheumatoid arthritis: therapeutic efficacy and modulation of ROS/NF-κB/COX-2-related inflammatory signaling

BackgroundRheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by severe synovial inflammation, joint deformities, and progressive tissue destruction. Celastrol (Cel), a natural triterpenoid with anti-inflammatory and antioxidant ac…

HLA-DRB1*14 is associated with lower odds of symptomatic SARS-CoV-2 infection in Mexican individuals

Mexico has been one of the countries most affected by the COVID-19 pandemic. Several factors can influence the susceptibility to SARS-CoV-2 infection, particularly highly polymorphic genes in the HLA system. Therefore, this pilot study analyzed the ass…

Multi-omics and machine learning reveal LYZ and ISG15 as diagnostic and therapeutic targets in autoimmune-mediated chronic kidney disease

BackgroundCKD represents a substantial worldwide health challenge, defined by the gradual development of tubulointerstitial fibrosis and reduced renal performance. Autoimmune-mediated factors are central to this pathological process, yet early diagnost…

Reporter immunogenicity as a defined rejection antigen: a noninvasive platform for skin transplant immunobiology

BackgroundPreclinical transplantation models largely rely on macroscopic or terminal assessments of graft fate, limiting longitudinal evaluation of immune rejection and tolerance induction. Reporter proteins such as enhanced green fluorescent protein (…
