Combating sars-cov-2 through lipoxins, proteasome, caveolin and nuclear factor-κb pathways in non-pregnant and...

Area of Science:

• Virology
• Cell Biology
• Immunology

Background:

• Severe acute respiratory syndrome coronavirus (SARS-CoV-2) exhibits significant mutation and adaptation capabilities.
• The ongoing pandemic and high mortality suggest SARS-CoV-2 may use multiple cellular entry routes and damage mechanisms.
• The angiotensin-converting enzyme II (ACE2) pathway is widely studied but may not be the sole entry point for SARS-CoV-2.

Purpose of the Study:

• To investigate alternative cellular entry pathways utilized by SARS-CoV-2 beyond the ACE2 receptor.
• To highlight the importance of understanding diverse viral entry mechanisms for developing effective treatments.
• To emphasize the need for therapeutic strategies targeting multiple pathways for COVID-19 patients, including pregnant women.

Main Methods:

• Review of scientific literature on SARS-CoV-2 cellular entry mechanisms.
• Analysis of viral adaptation and mutation data.
• Identification of key cellular pathways involved in viral entry and pathogenesis.

Main Results:

• SARS-CoV-2 employs multiple pathways, including nuclear factor-κB (NF-kB), caveolae, clathrin, lipoxin, serine protease, and proteasome pathways, in addition to ACE2.
• These pathways are critical for viral entry and subsequent cellular damage.
• Understanding these alternative pathways is essential for comprehensive therapeutic development.

Conclusions:

• Rethinking the exclusive focus on ACE2 is necessary for understanding SARS-CoV-2 pathogenesis.
• Developing drugs that modulate these diverse pathways could offer significant benefits for patients in the acute phase of COVID-19.
• Adapting treatment strategies for pregnant women with SARS-CoV-2 requires consideration of these multiple entry pathways.
