- 1.Zinc improves the structure of cilia, increasing their functioning; zinc allows more tight junctions form, which can help prevent virus entry
- 2.Zinc prevents the SARS-CoV-2 virus from binding to the ACE2 receptors; zinc inhibits RdRp from being transcribed
- 3.Zinc increases IFNa actions, forming more antiviral proteins
- 4.Zn inhibits IKK action, reucing inflammation
- 5.Zinc prevents bacterial growth

Zn lung association and SARS-CoV-2

- Zn2+ may have an anti-inflammatory effect on the lungs of those with pneumonia
- In a study done on rats, those that were lacking zinc ended up have increased expression of proinflammatory receptors, resulting in lung damage
- Hyperoxia can be regulated to prevent lung injury though the zinc and nitric oxide pathways
- Zn can lower neutrophil count in the lowering the chances of acute lung injury
- Zn inhibited phagocyte action
- Zinc can prevent bronchiolitis, bronchitis, and pneumonitis in children
- Patients with sepsis have low serum Zn concentration, increasing cytokine production and the likelihood of inflammation

Michigan State University

- Zinc helps regulate the immune system
- Zn2+ can serve as an antiviral agent 
- Zn2+ inhibits the replication of the SARS-CoV-2 virus
- Chloroquine allows Zn2+ ions to enter the cell
- When Zn2+ is used in alcoholics, after being released from papain-like protease in SARS-CoV, it results in the adverse effect of protein damage
- Zn2+ aids WBCs in interferon production 
- At doses greater than 75 mg each day, zinc (particularly zinc acetate) was shown to increase recovery in those with a cold
- Children presenting with RSV (respiratory syncytial virus) pneumonia has low levels of zinc
- Zn prevents RSV from replicating
- Zn2+ may have an anti-inflammatory effect on the lungs of those with pneumonia
