Sarcopenia, the age-related loss of skeletal muscle mass and strength, is closely associated with physical functional limitations, frailty and poor quality of life [1–3].Accumulating evidence suggests that obesity and excessive intake of saturated fatty acids can exacerbate sarcopenia [4–6], leading to a higher risk of metabolic … WebbThere are two types of MHC: MHC-1 and MHC-2. MHC I displays endogenous antigens, or antigens from within the cell, while MHC II displays exogenous antigens, or antigens from outside the cell. These outside antigens are obtained by way of phagocytosis, so only phagocytes in the body have MHC-2.
