Neuroimmune responses in viral infection

Abstract

The regulation of the immune responses is important in maintaining good health. Interactions between the nervous and immune systems are increasingly studied and widely appreciated to be influential in orchestrating immune responses. T cells express adrenergic receptors (AR) that enable them to respond to neurotransmitters produced by the sympathetic nervous system (SNS), noradrenaline (NA) and adrenaline, inducing downstream signalling and modulating cell functions, although whether this is stimulatory or inhibitory in T cell antiviral responses is unclear. In this thesis, I examine the effects of SNS in various models of viral infection through chemical sympathectomy and treatment with AR..
