AB We have recently shown that CD30, a member of the tumor necrosis
factor/nerve growth factor receptor superfamily, is preferentially
expressed by human T cell clones producing T helper (Th) type 2
cytokines. We report here that costimulation with an agonistic anti-CD30
monoclonal antibody enhanced antigen (Ag)-induced proliferation and
cytokine secretion by established human Th2 and Th0 clones. Moreover,
costimulation of peripheral blood mononuclear cells with the same
anti-CD30 monoclonal antibody resulted in the preferential development
of Ag-specific T cell lines and clones showing a Th2-like profile of
cytokine secretion. In contrast, early blockade in bulk culture of CD30
ligand-CD30 interaction shifted the development of Ag-specific T cells
towards the opposite (Th1-like) phenotype. Taken together, these data
suggest that CD30 triggering of activated Th cells by CD30
ligand-expressing Ag-presenting cells may represent an important
costimulatory signaling for the development of Th2-type responses.
