title: [Isolation of a monokine with a macrophage replacing activity for the induction of the antibody response to sheep red blood cells in vitro].
abstract: Macrophages are required for the induction of the immune response in vitro; it is known, however, that in the case of a particulate antigen such as red blood cells, macrophages can be replaced by a culture supernatant obtained from peritoneal cells. In the present paper we have studied the compound responsible for this activity, and compared it with the monokine Interleukine 1 obtained from activated macrophages: it has a different molecular weight: 35 K instead of 15 K and, in contrast with Interleukine 1, this compound is without effect on the proliferation of thymocytes.
