... We sought to elucidate if 1F5 was being cross-linked in vivo, as was suggested by in vitro findings. Since human IgG1s are known to react with mouse Fc receptors (FcRs), we considered FcR-mediated cross-linking as a likely mechanism. To test this hypothesis, we introduced a point mutation into the F ...

Psychoneuroimmunology
Psychoneuroimmunology (PNI), also referred to as psychoendoneuroimmunology (PENI), is the study of the interaction between psychological processes and the nervous and immune systems of the human body. PNI takes an interdisciplinary approach, incorporating psychology, neuroscience, immunology, physiology, genetics, pharmacology, molecular biology, psychiatry, behavioral medicine, infectious diseases, endocrinology, and rheumatology.The main interests of PNI are the interactions between the nervous and immune systems and the relationships between mental processes and health. PNI studies, among other things, the physiological functioning of the neuroimmune system in health and disease; disorders of the neuroimmune system (autoimmune diseases; hypersensitivities; immune deficiency); and the physical, chemical and physiological characteristics of the components of the neuroimmune system in vitro, in situ, and in vivo.
