Mesangiolysis associated with severe glomerular endocapillary proliferation of CD57 large granular lymphocytes

Abstract

A 54-year-old man developed renal failure, with renal biopsy findings of diffuse mesangiolysis with severe endocapillary proliferation. Immunohistochemical studies revealed that CD3-CD56-CD57+ large granular lymphocytes were present predominantly within glomerular tufts. Intercellular adhesion molecule-1 was more preferentially expressed in the glomerular endothelial cells with severe endocapillary proliferation as compared to those without endocapillary proliferation. These findings suggest that CD57+ large granular lymphocytes caused glomerular endothelial injury by a cell-mediated cytolytic mechanism, resulting in the development of mesangiolysis and microaneurysm formation.

Cell Adhesion Molecules in the Brain

Cell adhesion molecules found on cell surface help cells bind with other cells or the extracellular matrix to maintain structure and function. Here is the latest research on their role in the brain.
