The CD98 transporter system (SLC7A5/SLC3A2) mediates the entry of leucine and other BCAAs into cells, which can drive mTORC1 activation and enhance glycolytic metabolism, thereby promoting the expression of pro-inflammatory genes such as IL-1, TNF-, and C-X-C motif chemokine ligand 10 (CXCL10) ( Overall, the role of BCAA metabolism in macrophage polarization is more appropriately defined as an integrative module of nutrient sensing and energy metabolism, and its biological output is jointly influenced by dose, metabolic state, inflammatory stage, and the tissue microenvironment
If that is the case, then let me tell you that you are not alone
NAD therapy helps restore these levels, supporting mitochondrial function, improving focus, enhancing mood, and promoting healthier aging from the inside out.
