Research Interests

Over the years, Dr. Taylor has conducted directed to elucidating CNS mechanisms underlying the effects of stress, hormones, and drugs on neuroendocrine and neuroimmune functions in collaboration with Dr. Chiappelli and Drs. Hodgson and Yirmiya, two international fellows sponsored by the Cousins Center for PNI. This research has involved both developmental and adult paradigms. Their recent studies have identified a consistent pattern of enhanced neuroendocrine and behavioral responses to stress and psychoactive drugs in adult rats that were exposed to ethanol in utero, which replicates to a large extent the clinical conditions of fetal alcohol syndrome and fetal alcohol effects. Recognizing that prenatal factors affect neural and endocrine systems, which are intimately involved in immunological responses, in further work they demonstrated adverse effects of alcohol on immune competence following prenatal as well as adult exposure. Interestingly, these outcomes were more pronounced in male than in female subjects. Their recent studies in collaboration with Dr. Beylin on brain-immune interactions demonstrated blunting of the febrile and sickness behavior componenets of the acute-phase response to challenge with ecnotoxin and IL-1B, a proinflammatory cytokine induced by endotoxin. Furthermore, they have provided evidence that a reduction in hypothalamic cytokines, in particular IL-1B, accompanied the blunted febrile response (Taylor et al, 2002). In order to generalize the findings to another condition that induces brain cytokines, they have recently begun to study the febrile and sickness behavior components of the acute-phase response to traumatic brain injury.

Principal Investigator: Anna N. Taylor
Agency: Department of Veterans Affairs

The major goals fo this continuing project are to define the neural and / or hormonal mechanisms for the attenuated febrile response to endotoxin in adult alcohol-consuming rats.
