The interactions between the immune system and psychological states ar
e both intricate and intriguing, Research at a molecular level has thr
own considerable light on the previously ill-defined area of psychoneu
roimmunology. In this report, we explore the psychoneuroimmunology of
autoimmune disorders, particularly rheumatoid arthritis and lupus eryt
hematosus. Animal models of these diseases have provided a particularl
y useful window on complex psychoneuroimmunological interactions. Obse
rvations about the effect of stress on the onset and course of autoimm
une disorders has added to our understanding of psychoneuroimmunologic
al interactions. These interactions are bi-directional, as reflected i
n the autoimmune-mediated neuropsychiatric manifestations of systemic
lupus. Exploring the role of various neurotransmitters and neuromodula
tors in the stress response may have important therapeutic implication
s for autoimmune disorders. Copyright (C) 1996 Elsevier Science Ltd
