Targeting purinergic receptors to suppress the cytokine storm induced by SARS-CoV-2 infection in pulmonary tissue.

Int Immunopharmacol 2021 Sep 13;100:108150. Epub 2021 Sep 13.

Graduate Program in Medical Sciences, Federal University of Fronteira Sul, Chapecó, SC, Brazil. Electronic address:

The etiological agent of coronavirus disease (COVID-19) is the new member of the Coronaviridae family, a severe acute respiratory syndrome coronavirus 2 virus (SARS-CoV-2), responsible for the pandemic that is plaguing the world. The single-stranded RNA virus is capable of infecting the respiratory tract, by binding the spike (S) protein on its viral surface to receptors for the angiotensin II-converting enzyme (ACE2), highly expressed in the pulmonary tissue, enabling the interaction of the virus with alveolar epithelial cells promoting endocytosis and replication of viral material. The infection triggers the activation of the immune system, increased purinergic signaling, and the release of cytokines as a defense mechanism, but the response can become exaggerated and prompt the so-called "cytokine storm", developing cases such as severe acute respiratory syndrome (SARS).

[Progress in the relationship between NLRP3 inflammasome and lung injury in COVID-19].

Xi Bao Yu Fen Zi Mian Yi Xue Za Zhi 2021 Sep;37(9):844-850

Department of Microbiology, Shandong Traditional Chinese Medicine University, Jinan 250000, China. *Corresponding author, E-mail:

Severe inflammatory responses are considered responsible for acute lung damage in COVID-19. SARS-CoV-2 enters lung cells via ACE2, and the NLR family pyrin domain containing 3 (NLRP3) inflammasome and the pro-caspase-1 are then activated, followed by release of mature IL-1β and IL-18 and other inflammatory cytokines, thereby leading to inflammation and apoptosis. This inflammatory process induces syndromes such as inflammatory cell infiltration, congestion, and edema in the lungs of COVID-19 patients. Read More
