HSPA2 and type 1 diabetes mellitus: Additionally, elevated HSPA2(HSP70) expression, previously identified in biopsies of the terminal branch of the posterior interosseous nerve in the forearm of type 1 diabetes (Ising et al., 2023), in the distal nerve end acting as a molecular chaperone might assist proper protein folding and degradation (Stetler et al., 2010), promoting neuronal survival and functional recovery.
