Involvement of multiple factors in the clonal deletion of self-reactive T cells.

Journal Article (Journal Article)

Self-tolerance is primarily induced by the elimination of potentially self-reactive T cells during early development of the T cell repertoire. In the mouse, endogenous mouse mammary tumor viruses (MMTV), including minor lymphocyte-stimulating antigens and milk-transmitted exogenous MMTV, have been known to function as self-antigens inducing the clonal deletion of self-reactive T cells in a V beta-specific manner. We investigated the factors involved in the deletion of V beta 17a-bearing T cells. The results indicated that in addition to the previously reported V beta 17a deletion ligand, Mtv-3, there is a nonmilkborne gene product which progressively deletes V beta 17a (and V beta 3)-bearing T cells during aging. This suggests that clonal deletion is mediated by multiple factors and that a clonal deletion element associated with aging may play a significant role in shaping the T cell repertoire.
