Fab fragment of anti- E. chaffeensis immunoglobulin G complexed with E. chaffeensis did not induce any of these three cytokines, indicating that ehrlichial binding is required for IL-1beta mRNA expression and that binding of the immune complex to the Fc gamma receptor is required for TNF-alpha and IL-6 mRNA expression and enhanced IL-1beta mRNA expression .
 IL-6 mRNA, IL-1beta mRNA, TNF-alpha, Fc gamma receptor, IL-1beta, anti- E. chaffeensis immunoglobulin G, IL-1beta mRNA, IL-1beta, IL-6, immune complex
