HSPD1 and respiratory failure: Other studies have demonstrated a similarity between SARS-CoV-2 and human proteins, including pulmonary surfactants (10), brainstem neuronal proteins (11), chaperons (12), heat shock proteins 60 and 90 (13), ankyrin 1 (an erythrocyte membrane protein) (14), odorant receptor 7D4, poly (ADP-ribose) polymerase family member 9 (PARP9), and solute carrier family 12 member 6 (SLC12A6) (15), which have been hypothesized to contribute to lung disease, respiratory failure, endothelitis, neuroimmune diseases, autoimmune hemolytic anemia (AIHA), leukopenia, and vascular damage.
