title: [Cytokines as mediators of neuroimmune interactions].
abstract: Cytokines regulate numerous physiological and pathological processes in the central nervous system (CNS), i.e. they function both as immune regulators and neuromodulators. Acting upon the CNS via different ways, cytokines, mainly proinflammatory ones IL-1beta and TNF-alpha, can disturb physiological functions of the CNS, cause neurotoxic and neurodegenerative damage and stimulate IL-1beta synthesis in hypothalamus nuclei and posterior pituitary. They can produce stress-like effects upon the CNS and affect the activity of the axis hypothalamus--pituitary--adrenal glands, levels of neuropeptides in hypothalamic regions of brain, synthesis and utilization of central monoamines. These influences can implement the effects of sensitization, which enhances neuroendocrine responses to later stresses. Microglia and astrocytes, secondary messengers and interaction between hypothalamus and anterior pituitary play an important role in range of these processes as well as in the maintenance of Th1/Th2 cytokine balance.
