From immunoglobulin A nephropathy to primary focal segmental glomerulosclerosis, sparsentan expands its indications. Complement inhibitors offer new hope for patients with certain poor-prognosis glomerulonephritides. Semaglutide enjoys great success, promising nephro- and cardioprotection for type 2 diabetics.

The major hurdle of xenotransplantation is the immune response triggered by human natural antibodies interacting with carbohydrate antigens on the transplanted animal organ. Specifically, terminal glycoprotein motifs such as galactose-α1,3-galactose (α-Gal) and N-glycolylneuraminic acid (Neu5Gc) are significant obstacles. Little is known about the abundance and compositions of asparagine-linked complex carbohydrates (N-glycans) carrying these motifs in mammalian organs.

Clinical XTx may require off-site procurement in a designated pathogen free (DPF) facility necessitating a period of cold ischemic time during transportation. This study evaluates the impact of different kidney preservation strategies on early graft function in pig-to-baboon XTx in a series of eight cases of pig-to-baboon xenotransplantation performed after five hours of cold ischemic time and compares these results to six cases of pig-to-baboon xenotransplantation performed with minimal ischemic time.

BKV strains fall into four distinct genotypes (BKV-I, -II, -III, and -IV) with more than 80% of individuals are seropositive against BKV-I genotype, while the seroprevalence of the other four genotypes is lower. PyVAN and PyVHC occurs in immunosuppressed (e.
