Abstract/OtherAbstract:
Human tonsil B cells include a subpopulation (30 per cent) of cells which lack LFA-1 antigen. Activation of tonsil B cells by culture with anti-IgM and interleukin-4 led to an increase in staining intensities and in the proportion of cells staining, until by 48 h the majority of B cells were positive. Culture of activated cells with low-molecular weight B cell growth factor, which induces a proportion of cells to proliferate, led to a minor further increase in expression of the LFA-1 antigen. Inclusion of a monoclonal antibody against the LFA-1 beta chain in culture did not affect either proliferation or immunoglobulin secretion. The expression of LFA-1 by B cells thus changes as B cells are activated, perhaps reflecting the changing requirements of B cells for interaction with other cells and tissue components. On the other hand, our results did not provide any support for the idea that the LFA-1 antigen is directly involved in the interaction of B cells with lymphokines which control proliferation and differentiation.
