TAAR1 and cancer: Pharmacologically elucidating TAAR1 signaling, both generally with regard to TAAR1 as a protomer in receptor-receptor and/or receptor-protein complexes, or more specifically in cancer cellular phenotypes, will predictably lead to a better understanding of the mechanisms by which cancer alludes the immune system, and moreover, how drugs of abuse and other ligands for TAAR1 can contribute to cancer development, prognosis, and treatment.
