The pulmonary endothelium is a highly regulated organ that performs a wide range of
functions under physiological and pathological conditions. Since endothelial dysfunction …

The current epidemic of corona virus disease (COVID-19) has resulted in an immense
health burden that became the third leading cause of death and potentially contributed to a …

Objectives Angiotensin-converting enzyme 2 (ACE2) represents the primary receptor for
SARS-CoV-2 to enter endothelial cells. Here we investigated circulating ACE2 activity to …

Aims Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds to angiotensin
converting enzyme 2 (ACE2) enabling entrance of the virus into cells and causing the …

Purpose Low vitamin D in COVID-19 have been related to worse outcomes. However, most
of the studies conducted so far were not-controlled and retrospective, including biases …

Monoclonal antibodies targeting the SARS‐CoV‐2 spike (S) neutralize infection and are
efficacious for the treatment of COVID‐19. However, SARS‐CoV‐2 variants, notably …

Angiotensin converting enzyme 2 (ACE2), a transmembrane glycoprotein, is an important
part of the renin-angiotensin system (RAS). In the COVID-19 epidemic, it was found to be the …

Since the spread of the deadly virus SARS-CoV-2 in late 2019, researchers have restlessly
sought to unravel how the virus enters the host cells. Some proteins on each side of the …

Mortality in acute infections is mostly associated with sepsis, defined as 'life-threatening
organ dysfunction caused by a dysregulated host response to infection'. It remains …

Background The renin-angiotensin-aldosterone system was shown to be activated in severe
COVID-19 infection. We aimed to investigate the relationship between angiotensin …
