title: Correlation between the biologic functions and the generation of lymphokines in T cell clones.
abstract: We have recently reported that various murine T cell clones produce IL-1. Based on this observation we have analyzed in the present study the correlation between the biological functions and the generation of different lymphokines in (T,G)-A--L specific CD4+ clones. One subset of clones--the "helper clones"--were found to provide help to primed B cells, in vitro. These cells could be shown to produce IL-1, IL-2, and B cell stimulatory factor 1 (IL-4) activities and to express mRNA encoding for these three cytokines. The second subset of clones, termed "proliferative clones", were unable to help B cells in vitro but expressed vigorous Ag-dependent proliferations. These cells did not express IL-1, IL-2, or IL-4 activities. They produced another lymphokine(s) which may be granulocyte-macrophage-CSF, or some other factor recognized by the HT2 cell line. This study further substantiates the link between T cell activities and lymphokine repertoire with a special emphasis on the potential role(s) of T cell-derived IL-1.
