Abstract

The major metabolic product of ethanol is acetaldehyde. It is highly reactive with proteins. In situ this modification is significant enough to generate an antibody response. Whether an effector cellular immune response can be generated against these acetaldehyde modified adducts on syngeneic cells is not known. In this paper we have demonstrated in the murine system that acetaldehyde modified splenic cells can generate cytotoxic T lymphocytes (CTL). These CTL are specific for the acetaldehyde modified syngeneic cells, and not acetaldehyde modified allogeneic cells. The ability of the CTL to lyse specific targets is dependent on the formation of stable acetaldehyde adducts. Cold target inhibition studies reveal that modified syngeneic cells can inhibit lysis as effectively as unmodified cells. Therefore, the present study lends support to the hypothesis that acetaldehyde modified cells can generate a cellular immune response and may do so in pathologic states.
