Opioids and opioid peptides have been shown by numerous laboratories to modulate various parameters of the immune response, but little attention has been given to the type of opioid receptor that might be involved. This study focuses on the in

For ectothermic vertebrates, such as reptiles, the effects of opioid receptor subtype activation on breathing are poorly understood. On the basis of previous studies on mammals and lampreys, we hypothesized that mu- and delta-opioid receptor (MOR and DOR, respectively) activation
