Interleukin 1 (IL-1) and interleukin 6 (IL-6) are typical examples of multfunctonal pro-infammatory cytokines involved in the regulaton of the immune response, hematopoiesis, and infammaton. Both peripheral and intraventricular administraton of these cytokines causes acute phase symptoms, e.g. fever, actvaton of the hypothalamic-pituitary-adrenal axis and psychological depression. The amygdala belongs to the structures of the limbic system involved in the regulaton of the immune response. Increased actvity of immune system may lead to changes in the role of amygdala, medial prefrontal cortex, anterior cingulate cortex or insula. The aim of the study was to present the mutual interactons between the amygdala and pro-infammatory cytokines such as interleukin-1β (IL-1 beta) and interleukin 6 (IL-6). Most of the data included in this review comes from animal studies.
