Azobenzenearsonate-specific cloned mouse T cells able to transfer delayed hypersensitivity reactions in vivo produced macrophage agglutination factor (MaggF) after stimulation with mitogen or antigen in vitro. Mitogen (Con A) elicited MAggF production directly from T cells. Responses to Ag were Ag-specific, required syngeneic accessory cells in addition to T cells, and were independent of T cell fine specificity for azobenzenearsonate. Mouse MAggF shared a number of biochemical and immunochemical properties with the fibronectins (FN): 1) high Mr similar to that of plasma FN; 2) binding to gelatin, heparin, and polyclonal antibodies and mAb specific for cellular and plasma FN; 3) inhibition of activity in solution by monoclonal anti-human FN directed against plasma FN gelatin-binding domain; and 4) action on peritoneal exudate macrophages mediated through a FN-receptor cross reactive with one on human monocytes. MAggF production required active protein synthesis and was associated with significant increases in gelatin-binding immunoreactive FN (Mr 440 kDa on immunoblotting) in culture supernatants and T cell lysates. Metabolically labeled peptides could be precipitated by anti-FN from culture supernatants of activated T cells. Stimulated cultures contained significantly more cells with immunohistologically demonstrable cytoplasmic FN than unstimulated control cultures. We suggest that T cell FN is a distinct species of cellular FN which may play an important role in mediating delayed hypersensitivity inflammatory reactions in vivo.
