The ongoing Coronavirus disease 2019 (COVID-19) outbreak in China has become the world's leading health
headline and is causing major panic and public concerns. After emerging in the City of Wuhan, China, COVID-19 has
spread to several countries becoming a worldwide pandemia. Among the studies on COVID-19 it has been demonstrated
that novel coronavirus pneumonia is closely associated with inflammatory storms. Controlling the inflammatory response
may be as important as targeting the virus. Irisin is a muscle-contraction-induced immunomodulatory myokine related to
physical activity. Irisin drives the “browning” of white adipocytes, so enhancing metabolic uncoupling and hence caloric
expenditure. Irisin has been clearly shown to be a handyman molecule by exerting beneficial effects on adipose tissues, pancreas, and bone through “cross-talk” between skeletal muscle-adipocyte, skeletal muscle-pancreas, and skeletal musclebone, respectively. Irisin has been proposed as a promising strategy for early diagnosis and treatment of a various types of
cancers, neurological diseases and inflammatory conditions. Irisin has been demonstrated to suppress the immune response,
too. The importance of irisin is demonstrated by the increase in the number of scientific papers and patents in recent years.
The identification of irisin receptor should greatly facilitate the understanding of irisin’s function in exercise and human
health. This review examines the structure and recent advances on activities of irisin, suggesting it for further studies for the
prevention and cure of COVID-19. Nowadays, studies on irisin plasma levels and physical activity may be useful tools to
further investigate prevention of COVID-19. Irisin may be suggested as a potential novel intervention for COVID-19 by
mitigating inflammatory storms, suppressing immune response and simultaneously alleviating neurological disorders such
as depression and anxiety.
