This paper describes the experiments conducted in our laboratory on the mode of activation of CD5+ B cells. The data show that these cells are stimulated in a manner that is less dependent of T cell help as compared to CD5- cells and define IL-2 as the major growth and differentiation factor for CD5+ cells. These data are discussed in the light of the supposed function of CD5+ cells that seem represented by the capacity to release polyspecific antibodies reacting with a multiplicity of antigens from various pathogens. These antibodies, also called natural antibodies, probably represent one of the first lines of defense against invading microrganisms.
