Abstract

In the present study we attempted to clarify the effects of anti-beta 2-microglobulin (a-beta 2m) on lymphocyte activation. Neither a-beta 2m IgG fraction nor F(ab')2 had a mitogenic effect on either highly purified T or B lymphocytes alone, while their mitogenic effect was observed when T and B lymphocytes were appropriately reconstituted. When T lymphocytes were reconstituted with mitomycin C (MMC) treated B lymphocytes, a negligible decrease in the response to a-beta 2m was observed compared to the response of an untreated mixture to a-beta 2m. On the other hand, when B lymphocytes were reconstituted with MMC-treated T lymphocytes, the response was markedly diminished. It was found, moreover, that the response of T lymphocytes separated by a semipermeable membrane from MMC-treated B lymphocytes was not enhanced, while a mixture of T and MMC-treated B lymphocytes in the same chamber showed a marked response. These results lead to the conclusion that the cells responding to a-beta 2m are mainly T lymphocytes whose response is strongly enhanced by B lymphocytes, and that for the mitogenic effect of a-beta 2m direct cell-to-cell interaction between T and B lymphocytes is necessary.
