The Hsp70 TKD peptide is a synthetic fragment derived from the heat shock protein 70 (Hsp70), specifically the amino acid sequence TKDNNLLGRFELSG. In neurodegenerative disease research, Hsp70 and its derivatives are of interest due to their roles in protein folding, stress response, and immune modulation. The TKD peptide has been shown to activate natural killer (NK) cells and enhance immune surveillance, which may be beneficial in clearing damaged or aggregated proteins in neurodegenerative conditions. Its immunomodulatory properties suggest potential for therapeutic strategies aimed at enhancing neuroimmune interactions.
