Abstract
Mononuclear inflammatory cells (MIC) were analyzed in renal biopsies from 16 patients with ICGN (7 with glomerular immune complex deposits, 3 with anti-GBM disease, and 6 without immune deposits) by the avidin-biotin-immunoperoxidase technique utilizing monoclonal antibodies to cell surface antigens: T11 (total T), T4 (inducer/helper T), T8 (suppressor/cytotoxic T), B1 (B cells), M1 (monocytes/granulocytes), and Leu 7 [natural killer (NK) cells]. Total MIC were significantly increased in both glomeruli and interstitial tissues of the patients. Interstitial MIC consisted mainly of lymphocytes (80%) and monocytes (19%), with small numbers of B and NK cells present. In contrast, MIC in renal glomeruli of patients with ICGN were composed of monocytes (65%) rather than T lymphocytes (34%). A majority of T lymphocytes found in renal tissues of patients and controls had the helper/inducer phenotype. Tissue T4/T8 ratios were not significantly different in the glomeruli and interstitium. Monocytes and T lymphocytes accumulating in renal tissues of patients with ICGN may mediate glomerular injury in all forms of human ICGN.
