Abstract
Suboptimal concentrations of the anti-IL-4 receptor mAb M1 or M2 gave, in combination with IL-4, an enhanced proliferative response to the IL-4-responsive cell line D10.G4.1, compared to IL-4 alone. Increasing amounts of the M1 antibody inhibited the IL-4-dependent proliferation in a normal fashion. The enhanced IL-4-induced proliferation was only inhibited with the anti-IL-4 mAb 11B11, whereas the anti-IL-2 receptor antibodies had no effect. Addition of M1 or M2 antibodies to the IL-2-dependent cell line CTLL, known to express small amounts of IL-4 receptors and thereby also slightly responsive to IL-4, gave no enhanced IL-4-induced proliferation. Instead these antibodies were found to inhibit both the IL-4 as well as the IL-2-mediated CTLL proliferation.
