Abstract

The infrequent double light chain producing lymphocyte (DLCPL) is discussed in the context of allelic exclusion. Principally allelic selection rather than allelic exclusion would suggest a role for the DLCPL in the normal B cell population rather than as an aberrance of B cell malignancy. Found primarily in the periphery, it is uncertain at what stage of B cell ontogeny the DLCPL might reside. Nevertheless, through the possible presentation of two functional surface receptors, the DLCPL could be capable of recognizing both self and nonself epitopes.
