Background: Furin
Proteolytic cleavage regulates several physiological processes in both health and disease (3). Abnormal activity or mutations in proteases, including furin, is associated with pathologies and diseases including cancer, cardiovascular disorders, diabetes, inflammation, neurological diseases, and autoimmune diseases (3). As mentioned above, furin also acts upon bacterial substrates, including anthrax and Shiga toxin, and many virus families such as Herpes-, Flavi-, and Corona-, leading to host infections. Furthermore, the novel coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) present with a S-spike protein that is cleaved by PCs, including furin, at the S1/S2 cleavage site (5, 6). The cleavage allows the SARS-CoV-2 to then attach to the angiotensin-converting enzyme 2 (ACE2) receptor via the S1 domain and the cellular membrane via the S2 domain (5, 6). Although COVID-19 patients mostly present with respiratory symptoms, a variety of other systems are affected including cardiovascular, gastrointestinal (GI), and the liver (5-7). It is suggested that the S1/furin/ACE2 interaction promotes SARS-CoV-2 infection leading to the harmful symptoms and reactions in patients (5, 6). Cardiovascular disease is a common comorbidity in patients, along with hypertension, myocardial damage, and heart palpitations (Ming). Further evidence of furin being a risk factor for infection is the high levels of furin present in the blood of heart failure patients (5). Similarly, the small bowel may be another interaction site for infection as it is rich in furin and the intestinal enterocytes have many ACE2 receptors (6). Furin is also highly expressed in the liver and hepatocytes and cholangiocytes of the liver present ACE2 receptors (3, 7). Studies have shown that up one-third of COVID-19 patients experience GI symptoms which range from diarrhea and loss of appetite to abdominal cramping and bloody stool (6, 7). Additionally, some patients displayed abnormal liver enzyme levels (7). It has been suggested that a possible therapeutic strategy for treating those infected with SARS-CoV-2 is pharmacologically or immunologically modulating furin or ACE2 binding sites to combat COVID-19 infection (3, 5).
