4. COVID-19 therapies
World Health Organization (WHO) reported that COVID-19 now becomes much more than a health crisis. Till present, curing COVID-19 remains elusive, despite of the great efforts directed by the researchers towards understanding and identifing the disease mechanisms. There is no doubt that COVID-19 can trigger airway inflammatory reactions, in which neutrophils play the major role in increasing the severity by inducing COVID-19-associated coagulopathy (Zuo et al.). In that context, several therapeutic strategies have been proposed to control COVID-19 (Cascella et al., 2020).
