Peritubular capillaries function in kidney

WebThe ultrastructural features of peritubular capillary (PC) damage was studied in 12 kidney allografts with acute humoral rejection (AHR). AHR manifested in diffuse linear PC staining for C4d, and histology consistent with Banff grade III in 7 recipients and Banff grade II in 5. Allografts with acute tubular necrosis served as controls. First biopsies … WebThis postglomerular blood, which has a relatively high concentration of protein and red cells, enters the peritubular capillaries where the high oncotic pressure resulting from the high protein concentration facilitates the reabsorption of fluid. The peritubular capillaries coalesce to form venules and, eventually, the renal vein.
