Cell electrophoretic studies on mouse lymphocytes treated with concanavalin A: possible existence of two types of receptors on cell surface. 1979

K B Sainis, and A N Bhisey, and K Sundaram, and G P Phondke

Concanavalin A (Con A) induced biphasic changes in the electrophoretic mobility (EPM) of splenic lymphocytes of AKR mice. At low concentrations of Con A (2-12.5 mug/ml) there was a significant increase in there was a significant increase in the EPM which could be attributed to the redistribution and endocytosis of Con A receptors. At higher concentrations (greater than or equal to 15.0 mug/ml) a reduction in EPM below that of untreated cells was possibly due to the binding of excess Con A after redistribution. The biphasic profile of EPM was observed only in respect of Con A-treated T lymphocytes. The EPM of B lymphocytes, despite binding of Con A, remained unaltered at all concentrations of Con A. On the basis of these data, the existence of two types of Con A receptors on the cell surface is proposed and their status vis-a-vis the redistribution is discussed.

D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
