In addition, studies have described the likely occurrence of the “bradykinin-related peptides storm” at the pulmonary site in addition to events related to the “cytokine storm” during the clinical progress of COVID-19 (Karamyan, 2021; Yin et al., 2021), which altogether could positively modulate the expression of the B1R in the lung as well as in organs distant from the SARS-CoV-2 infection site (Zamorano Cuervo and Grandvaux, 2020; McCarthy et al., 2021). This evidence concerns the gene KNG1 and COVID-19.
