SARS-CoV-2 induced changes in the lungs based on autopsy cases.

Context: Researchers throughout the world devote enormous efforts to reveal the peculiarities of the pathogenesis of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, however, it continues to surprise and cause the death of millions of people.

Aims: This article aims to study the molecular mechanisms provoked by SARS-CoV-2, the virus-induced changes in Angiotensin-converting enzyme 2 (ACE2) functionality, in the vascular homeostasis through CD34 expression, B-cell immunity through the expression of CD20 and CD79α, and adhesion molecules through E-cadherin.

Settings And Design: This was a prospective, descriptive, and observational study.
