By activating three distinct vasopressin receptor isoforms called V1a-R, V1b-R (V3-R) and V2-R, vasopressin (VP) mediates a wide number of biological effects in mammals and may be involved in several pathological states. Up to now only specific V1a and V2 receptor agonists and antagonists have...
Functional activation studies of posttraumatic stress disorder (PTSD) using symptom provocation paradigms have implicated dysfunction in limbic and paralimbic brain regions. Increased or altered cerebral blood flow has been observed in amygdala and insula. Decreased or absent activity has been...
We present a psychoneuroimmunologic (PNI) model for Human Immunodeficiency Virus (HIV) infection, describe a 10-week group-based cognitive behavioral stress management (CBSM) intervention and summarize research demonstrating the effects of this intervention on mood, neuroendocrine (Hypothalamic...
As numerous coping strategies to deal with stressors can be used concurrently or sequentially, it may be productive to consider coping from a broad, systemic perspective. Using profile analysis and multivariate techniques, we demonstrated that coping profiles comprising multiple strategies...
Metabotropic glutamate (mGlu) receptors, which include mGlu1-8 receptors, are a heterogeneous family of G-protein coupled receptors (GPCRs) that function to modulate neuronal excitation and plasticity via pre-synaptic, post-synaptic and glial mechanisms. Agonists for group II mGlu receptors...
The hypothalamus pituitary adrenal (HPA)- axis is one of the major output systems of the neuroendocrine stress response. Its major end products, glucocorticoids (GCs), have a plethora of effects throughout the organism, most of which are believed to be protective against disturbances of...
Immediately after infection, Human immunodeficiency virus, type 1 (HIV-1) enters the central nervous system (CNS) and is localized in highest concentration in the hippocampus and basal ganglia. Since these areas are associated with HPA axis and autonomic activities as well as cognition, it has...
Clinical reports of depersonalization suggest that attenuated emotional experience is a central feature of the condition. Patients typically complain of emotional numbness and some patients ascribe their feelings of unreality to a lack of affective "colouring" in things perceived. Recent...
