Autoimmune Processes Involved in Organ System Failure Following Infection with SARS-CoV-2.

Adv Exp Med Biol 2021 ;1318:355-368

Biological Safety and Security, Frederick, MD, USA.

During the COVID-19 pandemic associated with high incidence, transmissibility, and mortality, this chapter focuses on three phases of the disease: initial exposure, initiation of the immune response to the agent, and finally, an inflammatory/autoimmune-like presentation with pulmonary, neurological, and renal failure and disseminated intravascular coagulation which occurs in a small proportion of the patients. The elegant demonstration of the site of interaction between the spike (S) protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is the causative agent of COVID-19, and the ACE (angiotensin-converting enzyme) 2 receptor of cells distributed throughout the body has enabled research efforts to develop pharmacological and immune countermeasures to the viral phase of the disease. This chapter rapidly reviews the molecular and structural organization of SARS-CoV-2 and its interaction with ACE2. Read More
