Mosnaim has served as a Consultant to the Pan American Health Organization (1982–1985), Member of the United States Pharmacopeia Convention (1990 and 1995), and Director of International Neuropsychiatry Consultants (1987–2020). Additionally, he is a Fellow of The Chemical Society (1977) and a Senior Fellow of the American Institute of Therapeutics (2019).[1]
In 1971, Mosnaim joined the University of Health Sciences/The Chicago Medical School as an assistant professor in the Department of Pharmacology. He was promoted to Associate Professor and Acting Chairman (1974), and to a Full Professorship in 1979. He has been serving as a professor of Cellular and Molecular Pharmacology and adjunct professor of Psychiatry and Behavioral Sciences at The Chicago Medical School/Rosalind Franklin University.[1]
Mosnaim holds an Honorary Full Professorship at the University of Chile College of Pharmaceutical Sciences.
Mosnaim has published over 150 papers in peer-reviewed Journals, more than 20 invited reviews and book chapters, and presented research in more than 200 scientific meetings.[2]
Early in his research career (1967), Mosnaim contributed to elucidate the metabolic pathway of the then widely used toxic insecticide DDT (dichlorodiphenyltrichloroethane), and in a series of publications (1969–1972) helped to understand the mechanism of halogenation by cupric salts of carcinogenicanthracene and pyrene compounds.[6] His laboratory demonstrated the presence of phenylethylamine, commonly viewed as the endogenousamphetamine, in mammalian tissues, and his work elucidated this amine’s in vivo and in vitro brain metabolic pathway.[7][8][9] His work, animal models, contributed to establish phenylethylamine brain levels as a biological marker for various neuropsychiatric disorders, and to evaluate its brain changes in response to different classes of psychotropic drugs.[10][11] Further research identified some of the physiological functions, and described relevant behavior and toxicological effects of phenylethylamine and various structurally related trace amines.[12][13]
Mosnaim reported plasma levels of the endogenous opioid pentapeptide methionine-enkephalin in various patient populations, and the effect of selected classes of drugs on its degradation kinetics,[14] suggesting that its significant increase in chronic cluster and migraine patients during an acute headache episode could serve as a biological marker for these illnesses.[15][16] He also clarified reports of the activity of platelet monoamine oxidase and the role of dietary phenylethylamine and tyramine in the etiology of migraine headaches.[17]
Mosnaim contributed to document the association of tardive dyskinesia and drug-induced parkinsonism, and in identifying sub-types, cognitive deficits, and some of the risk factors associated with increased vulnerability to this condition.[18][19][20][21] He participated in studies finding comorbidity of pain, dermatological and allergic conditions, as well as decreased natural killer cell activity, in posttraumatic stress disorder patients.[22] He reported the decrease of this immune function in septic shock and human immunodeficiency virus-1 positive individuals, as well as its significant increase by various substances with widely different chemical structures and biological activities, e.g., enkephalins, α-interferon, interleukin-2, taxol, and lipopolysaccharide.[23][24][25]
