Summary of tissue protection by ET [24,32,38,45,46,47,48,51,52,53,54,55,56,57,58,59,60,62,63,64,68,74,98,101,104,105,131,183,184,185,186,187,188,189,190,227,228,236,242]. There is evidence to suggest that ET can accumulate in most (if not all tissues) in the body, especially those shown below. Based on present knowledge, the following diagram highlights how ET may protect various organs and tissues from oxidative damage and inflammatory injury amongst other cytoprotective effects in COVID-19 patients. The boxes in blue highlight systemic benefits for all tissues of the body [33,34,35,36,37,38,39,43,45,48,50,65,66,67,68,96,97,98,99,100,101,154].
