[In vitro comparison of 2 expressions of cellular immunity induced by a cutaneous allograft in the mouse].
A short-term test (5 h) has been compared to a long-term test (48 h) for evaluation of the cellular cytotoxic response which is induced in recipients of allografts. Spleen cells from mice recipients of skin allografts were tested. We have shown that the cellular cytotoxicity expressed in a short-term test is itself expressed during a short period whereas the cytotoxicity expressed in a long-term test is still detectable for months after a first skin graft. Moreover, the lytic activity of the spleen cells is much higher when it is expressed in a long-term test. The fact that we could get, in vitro, in two days, a low primary cellular cytotoxic response against alloantigens, makes likely that during the long-term test, the anamnestic response which can develop is especially responsible for the cellular cytotoxic response.
