Depletion of extracellular asparagine impairs self-reactive T cells and ameliorates autoimmunity in a murine model of multiple sclerosis
Amino acids play critical roles in the activation and function of lymphocytes. Here we show that the non-essential amino acid, asparagine, is essential for optimal activation and proliferation of CD4 + T cells. We demonstrate that asparagine depletion at different time points after CD4 + T cell activation reduces mitochondrial membrane potential and function
