Antimicrobial Agents Induce Monocytes to Release IL-1α, IL-6, and Tnf and Induce Lymphocytes to Release IL-4 and TNFτ

Abstract Evaluation was carried out on the action of different antibiotics on the release of cytokines. Experiments were done in vitro on monocytes and on human lymphocytes. Results show that the majority of the antibiotics tested are able to induce the release of one or more cytokines from their respective producing cells. Among the β-lactams the most active were the cephalosporins (cephalexin, cefamandol, ceftazidin, and a sulbactam-ampxcillin combination) in inducing the release of TNF, IL-1α and IL-6 from monocytes, and releasing IL-4 and IFN-τ from lymphocytes. The sulbactam-ampicillin combination and cefamandole were extremely active in the production of IFN-τ. Among the lincosamides, clindamycine notably stimulated the release of TNF and IL-6, while lincomycine induced a notable increment of IL-4 from monocytes. Teicoplanin is a very strong inducer of TNF, IL-1α and IL-6.
