Positive evolutionary pressure has apparently preserved the ability to synthesize chemically authentic morphine, albeit in homeopathic concentrations, throughout animal phyla. ... The apparently serendipitous finding of an opiate alkaloid-sensitive, opioid peptide-insensitive, µ3 opiate receptor subtype expressed by invertebrate immunocytes, human blood monocytes, macrophage cell lines, and human blood granulocytes provided compelling validating evidence for an autonomous role of endogenous morphine as a biologically important cellular signalling molecule (Stefano et al., 1993; Cruciani et al., 1994; Stefano and Scharrer, 1994; Makman et al., 1995). ... Human white blood cells have the ability to make and release morphine

Posttranslational processing can be illustrated by the cleavage and modification of proopiomelanocortin (POMC), the precursor of several peptides with distinct biological actions, including adrenocorticotropic hormone (ACTH), α-melanocytestimulating hormone (α-MSH; also called melanocortin), and β-endorphin.
