Isolated human PBMC from ten healthy volunteers were stimulated by staphylococcal enterotoxin B (SEB) and Staphylococcal toxic shock syndrome toxin-1 (TSST-1) superantigens with varying concentrations of tigecycline. Cytokines IL-1beta, IL-6, TNF-alpha, and chemokines MIP-1alpha and MIP-1beta concentrations were measured along with T cell proliferation. Results demonstrated that tigecycline alters cytokine production and reduces T-cell proliferation in vitro suggesting an immunomodulatory activity independent of its antimicrobial effect. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
