Cytokine networks initiated by means of innate immunity are regarded as a major determinant of host defence in response to acute infection by bacteria including Borrelia burgdorferi . Herein, we demonstrate that interferon ( IFN )‐α, either endogenously produced after exposure of cells to toll‐like receptor‐9‐activating CpG oligonucleotides or provided as recombinant cytokine, weakens activation of the anti‐bacterial interleukin ( IL )‐1/ IL ‐22 axis in human peripheral blood mononuclear cells exposed to viable B. burgdorferi . As IFN ‐α has been related to pathological dissemination of the spirochaete, data suggest an immunoregulatory role of type I IFN in this context that is able to significantly modify cytokine profiles thereby possibly determining early course of B. burgdorferi infection.
