In an attempt to clarify the participations of cellular immunity in the development of tubulo-interstitial lesions, aberrant expressions of major histocompatibility complex (MHC) class II antigens and Ki-67 nuclear antigen on the renal tubular epithelial cells were studied. Ki-67 antigen was known to appear in all phases of cell cycle except for Go. Nine normal kidney specimens (4 males and 5 females) and 117 kidney specimens obtained from patients with kidney diseases (54 males and 63 females) were examined with the indirect immunofluorescence technique using murine monoclonal antibodies against HLA-DR (lal), HLA-DQ (Leu10) and Ki-67 nuclear antigen. Patients included 100 with glomerular diseases, and 16 with tubulo-interstitial diseases consisting of 4 acute tubular necrosis (ATN), 7 acute tubulo-interstitial nephritis (AIN), one renal allograft rejection and 4 sarcoidosis. In normal kidney, HLA-DR was solely noted in only two specimens (22.2%) at the basal portion of proximal tubular epithelial cells. In tubulo-interstitial diseases 11 (68.8%) out of 16 patients showed diffuse and intense expressions of HLA-DR concomitant with HLA-DQ in 6 of 13 (42.9%), and 11 of 13 (84.6%) were positive for Ki-67 nuclear antigen. Especially, in AIN and allograft rejection, intense expression of HLA-DR, DQ and Ki-67 nuclear antigen were observed in 100%, 86%, 100%, respectively. In ATN 3(75%) were positive for HLA-DR and Ki-67, but not for HLA-DQ. In contrast, only 12(15.6%). 2(2.6%) and 2(4.8%) of primary glomerular disease were weakly positive for HLA-DR, DQ and Ki-67 nuclear antigen, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

D007684 Kidney Tubules Long convoluted tubules in the nephrons. They collect filtrate from blood passing through the KIDNEY GLOMERULUS and process this filtrate into URINE. Each renal tubule consists of a BOWMAN CAPSULE; PROXIMAL KIDNEY TUBULE; LOOP OF HENLE; DISTAL KIDNEY TUBULE; and KIDNEY COLLECTING DUCT leading to the central cavity of the kidney (KIDNEY PELVIS) that connects to the URETER.
