In this regard, available evidence shows that while morphine and heroin are liable to attenuate the immune response, long-acting opioids that are used in withdrawal treatment, such as methadone and buprenorphine, are largely devoid of immunosuppressive activity. Opioids can also influence the immune function through the activation of the descending pathways of the hypothalamus-pituitary axis (HPA) and the sympathetic nervous system (Vallejo et al., 2004). This review on role of opioidergic system in humoral immune response summarizes the effect of opiate receptor polymorphism on innate and adaptive immunity, identifies the role of the mu opioid receptor in these functions,. | NEUROIMAGING -METHODS Edited by Peter Bright Neuroimaging - Methods Edited by Peter Bright Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2012 InTech All chapters are Open Access distributed under the Creative Commons Attribution license which allows users to download copy and build upon published articles even for commercial purposes as long as the author and publisher are properly credited which ensures maximum dissemination and a wider impact of our publications.
