The effect of anti-tumor necrosis factor (TNF)-alpha monoclonal antibody on allergic cutaneous late phase reaction in mice.
Biphasic cutaneous reaction with peak response at 1 (early phase) and 24 to 48 hour (late phase) was elicited by epicutaneous challenge with antigen in actively and passively sensitized mice. Mice were actively immunized with dinitrophenylated (DNP) ascaris antigen and challenged with dinitrofluorobenzene (DNFB). Passively sensitization was carried out by the injection of monoclonal anti-DNP-IgE antibody into mice and challenge was elicited with DNFB. Prednisolone at doses of 3 to 10 mg/kg clearly inhibited both early and late phase reactions in either sensitized mice. Monoclonal anti-tumor necrosis factor (TNF)-alpha antibody inhibited the late phase cutaneous reaction in actively sensitized mice. Anti-interleukin-5 (IL-5) monoclonal antibody has no effect on both phase reactions in either actively and passively sensitized animals. These results indicate the possible participation of TNF-alpha in allergic cutaneous late phase reaction in actively sensitized mice.
