Anandamide is an endocannabinoid. Anandamide modulates both neuronal and immune functions through two protein-coupled cannabinoid receptors ( CB1 and CB2 ). Anandamide can activate numerous other receptors like PPARS , TRPV1 , and GPR18/GPR55 . Anandamide also has potential anti-fungal and anti-inflammatory activities. Anandamide can be used for the research of Alzheimer’s disease (AD) and ulcerative colitis.
