Article The Role of Zinc in Antiviral Immunity

Zinc is known to modulate antiviral and antibacterial immunity and regulate inflammatory response. In vitro experiments demonstrate that Zn2+ possesses antiviral activity through inhibition of SARS‑CoV RNA polymerase. Indirect evidence also indicates that Zn2+ may reduce the activity of angiotensin‑converting enzyme 2 (ACE2), known to be the receptor for SARS‑CoV‑2. Zinc possesses anti‑inflammatory activity by inhibiting NF‑κB signaling and modulation of regulatory T‑cell functions that may limit the cytokine storm in COVID‑19.
