Their study investigated the concentrations of tau, amyloid β 42 peptides, and cytokines (TNF-α, IL-6, IL-10) in neuron-derived exosomes from the peripheral blood of military personnel with or without mTBI, concluding that increased exosomal tau, amyloid β 42, and IL-10 concentrations could be found in the plasma of mTBI patients compared to the controls. This evidence concerns the gene IL10 and concussion.
