IL-5 responsive subsets among normal and lymphomatous murine B cells.

ABSTRACT

Two normal murine B-cell subpopulations, germinal center and coelomic B cells, and at least some of the lymphomas derived from them, respond to IL-5. In the case of normal B cells, a comitogen (DxS) is required. IFN-gamma is strongly inhibitory to proliferation of the coelomic B-cell subset but not for germinal center cells or the SJL lymphomas derived from them.
