The relationship between the immunoglobulin class of B-cell precursors and the degree of synergism obtained from the presence of T cells.

Abstract

In thymus–bone marrow synergy experiments the γG response is considerably more dependent on T-cell help than is the γM response. No difference in radiation sensitivity between γM and γG precursor cells could be detected. γG1–PFC were found to be more sensitive to a lack of protein in the suspending medium than γG2a or γM–PFC.
