Abstract

Lyme disease is a zoonosis caused by infection with bacteria belonging to the Borrelia burgdorferi species after the bite of an infected tick. Even though an infection by this bacterium can be effectively treated with antibiotics, when the infection stays unnoticed B. burgdorferi can persist and chronic post-treatment Lyme disease syndrome is able to develop. Although a cellular and humoral response is observed after an infection with theBorrelia bacteria, these pathogens are still capable to stay alive. Several immune evasive mechanisms have been revealed and explained and much work has been put into the understanding of the contribution of the innate and adaptive immune response. This review provides an overview with the latest findings regarding the cells of the innate and adaptive immune systems, how they recognize contribute and mediate in the killing of the B. burgdorferi spirochete. Moreover, this review also elaborates on the antigens that are expressed by on the spirochete. Since antigens drive the adaptive and, indirectly, the innate response, this review will discuss briefly the most important antigens that are described to date. Finally, there will be a brief elaboration on the escape mechanisms of B. burgdorferi with a focus on tick salivary proteins and spirochete antigens.
