Antigen receptor-mediated calcium signals in B cells as revealed by confocal fluorescence microscopy.

H Yamada1, J Mizuguchi, M Nakanishi.   

Abstract

A confocal fluorescence microscope was used to study the antigen receptor-mediated calcium signals in B cells. Anti-IgD binding to B lymphoma cells (BAL17) increased the intracellular calcium concentration with short lag times. Confocal fluorescence images of the fluo-3-loaded BAL17 cells showed that the intracellular calcium ion concentrations increased non-homogeneously, suggesting that the calcium signals transferred not only to the cytoplasm but also to the nucleus.
