A novel human coronavirus SARS-CoV-2 (also referred to as CoV-19) that emerged in
late 2019 causes Covid-19 disease a respiratory tract infection which provokes
about 4 million deaths per year. Unfortunately, to date, there is no specific
antiviral treatment for COVID-19. Mast cells (MCs) are immune cells implicated in
the pathogenesis of viral infections, where they mediate inflammation. Microbes,
including virus, activate MCs through TLR releasing chemical pro-inflammatory
compounds and cytokines. Although, in biomedical literature there are only few
reports on MCs activation by SARS-CoV-2 infection. The production of
pro-inflammatory cytokines by MC viral activation leads to increase pulmonary
inflammation and fibrosis. Sodium Chromo-Glycate (SCG) described as a MC
stabilizer, prevents the release of inflammatory chemical compounds, improve
mouse survival and respiratory pathological changes in lung viral infection and
suppresses inflammation. Furthermore, palmitoylethanolamide (PEA) a nuclear
factor agonist, an endogenous fatty acid amide, which exerts a variety of
biological effects, related to chronic inflammation and pain, is involved also in
MCs homeostasis with an inhibitory and protective effect on the respiratory tract
during viral infections. Here, we hypothesize for the first time, that SCG and/or
PEA suppress MC activation and pro-inflammatory mediators release, playing an
anti-inflammatory therapeutic role in the inflamed lung of patients with
COVID-19.
