denotes |
Elevated NET levels are found in COVID-19 patients [96]. |
T156 |
1801-1997 |
Sentence |
denotes |
NET formation is considered as a driver of COVID-19, since NET formation may contribute to tissue damage, organ injury, and mortality as indicated by autopsy specimens from COVID-19 patients [97]. |
T157 |
1998-2179 |
Sentence |
denotes |
The by-product of NETs, such as elastase, is involved in the pathogenesis of COVID-19 by facilitating SARS-CoV-2 entry and causing hypertension, thrombosis, and vasculitis [98–100]. |
T158 |
2180-2328 |
Sentence |
denotes |

T159 |
2329-2475 |
Sentence |
denotes |
Increased NETs are associated with hyperinflammation and in COVID-19 patients they amplify the severity and mortality associated with the disease. |

Sentence |
denotes |
Targeting NETs and its feedback loop, with elastase, DNase-1, or inhibitory peptides as well as IL-1β, are potential therapeutic interventions for reducing the severity of COVID-19 [102,103]. |
T161 |

T162 |
2782-3057 |
Sentence |
denotes |
Inflammasomes are cytosolic protein complexes consisting of multiple oligomeric molecules that detect cell-damaging agents and pathogenic factors by recognizing danger-associated molecular patterns (DAMP) and pathogen-associated molecular patterns (PAMP), respectively [104]. |
T163 |
3058-3169 |
Sentence |
denotes |

T164 |
3170-3276 |
Sentence |
denotes |
