Psychoneuroimmunology is the emerging science devoted to studying the two-way relationship between the nervous and immune systems. Psychoneuroimmunology, Stress, and Infection highlights the latest information concerning microbial infections in both man and animals as related to stress and especially stress hormones. The volume focuses on psychoneuroimmunology as it impacts the immune system in general and also the relationship between neurological events which influence susceptibility and/or resistance to infectious agents such as bacteria, fungi and viruses, as well as parasites. Prominent researchers describe the involvement of the hypothalamus-pituitary-adrenal (HPA) axis on immunity as a function of the nervous system. The text discusses hormones such as prolactin and growth hormone and steroid induced susceptibility to infection and neuropeptides, including vasoactive intestinal peptide, and substance P. The effects of catacholamines on immunity and susceptibility to infection are also covered. This reference also details the involvement of immune cells in the synthesis of neuropeptides, including hormones and endorphins, their effect on the brain as well as the effects of interleukins and tumor necrosis factor on the central nervous system. The book concludes with an interesting look at the relationship between aging, psychoneuroimmunology, and infection. Although there is much new knowledge concerning the nature and mechanism of immune responses, including the mediators involved, Psychoneuroimmunology, Stress, and Infection also presents important discussions and reviews that are long overdue and provide a major contribution to the area of biomedical knowledge in general and psychoneuroimmunology in particular.
