One analysis identified molecular structural similarities at the molecular level between COVID-19 peptide sequences and adhesion molecules expressed by neurons and Schwann cells Another noted potential for molecular mimicry between COVID-19 and heat shock proteins-60 and -90 (Hsp) (Lucchese and Flöel, 2020; Shang et al., 2021). This evidence concerns the gene HSP90B2P and COVID-19.
