studies of the mitogenic and polyclonal b cell activation properties of m1 carbohydrates indicated that b cell proliferation is induced in both xid ( lyb-3- , 5- ) and normal ( lyb-3- , 5- and lyb-3+ , 5+ ) splenic b cell subpopulations , but that differentiation to igm synthesis fails to occur in the lyb-3- , 5- b cell subpopulation .
