FABP4 and metabolic dysfunction-associated steatotic liver disease: More recently, FABP4 (a member of the FABP family that is normally expressed in adipocytes and macrophages [5]) is reported to be elevated in rodent models of both ALD and non-alcoholic fatty liver disease (NAFLD), as well as in serum and hepatic tissue from patients diagnosed with ALD or NAFLD [6,7].
