Goldwaser: A peptide is a small chain of amino acids, and amino acids are the building blocks of protein

Increased cellular senescence in aging also causes increased CD38, with a subsequent decrease in NAD+.[ref] T cells, immune cells, endothelial cells, and smooth muscle cells all can produce CD38, and it is upregulated by proinflammatory cytokines, cellular senescence, steroid hormones, and in response to bacterial infections.[ref] CD38 does a lot, including:[ref] regulating calcium ions and neurotransmitter release activation of T cells inhibits sirtuins both by reducing NAD levels and by generating a niacin metabolite that feeds back to inhibit SIRTs regulates the resolution of inflammatory response and tolerance of self (role in autoimmune diseases) limits NAD availability in bacterial infections (bacteria can use NAD for energy) Nicotinamide Riboside, NAD+ pathway, and Covid: Why Covid hits older adults hard NAD+ levels interact with the immune response in Covid patients in multiple ways: When someone is ill with COVID-19, the PARP genes are overexpressed, and NAD levels decrease
