Research interests in the pain field:

My main research interest has been in the bidirectional communication pathways between psychoneuroendocrine variables (such as stress and depression) and physiological defense systems, including the endogenous pain-inhibitory system and the immune system. My earlier work in the area of pain focused on the role of stress-related neuropeptides and opiates in modulation of pain and immunity. In the last few years, my focus of interest changed to the effects of immune activation and cytokine secretion on brain and behavior. In my studies I examine the neurobehavioral aspects of illness, using a variety of experimental models of infectious and autoimmune diseases in both animals and humans. Furthermore, I investigate the role of neuro-immune mechanisms (particularly brain interleukin-1 and tumor necrosis factor-alpha in mediating illness-associated changes in pain, ingestive, explorative, social and sexual behaviors, as well as emotional (particularly depression) and cognitive disturbances.
