Renal brushborder membrane vesicle. Study of marker enzymes and uptake of nutrients in Mycobacterium leprae infected mice.
The renal brush border membrane vesicles (BBMV) were used to elucidate the early biochemical functional status during the course of experimental M. leprae infection in mice. The activities of the characteristic brush-border enzymes viz: alkaline phosphatase, leucine amino peptidase and gamma-glutamyl transpeptidase were found to be significantly decreased (p less than 0.001) at 3 and 6 months after infection. The transport of nutrients viz: D-glucose, L-alanine, L-lysine and L-aspartate across BBMV showed similar pattern. The activity of brush border enzymes and transport of nutrients across the membrane returned to normal at 9 months post-infection suggesting regeneration of the brush border membrane.
