E3 ubiquitin ligase is often responsible for tagging aggregates using a small protein called ubiquitin, which targets the protein to the proteasome

Furthermore, hypoxia and metabolic reprogramming induced by ID contribute to immune escape mechanisms

This step is governed by a holoenzyme called glutamate-cysteine ligase which consists of a catalytic subunit (GCLC) and modifying subunit (GCLM)

Virus protein ligands, like trimeric spike glycoprotein interact with cellular receptors, such as ACE2, and host proteases, like transmembrane protease serine 2 (TMPRSS2), participate in virus entry by proteolytically activating virus ligands (Sallenave and Guillot, 2020
