1. Coronavirus infection is associated with a massive release of pro-inflammatory cytokines (e.g. TNF alpha and interleukins)
2. Pro-inflammatory cytokines can cause leaky vessels and lead to conditions like ARDS (lung disease)
3. NMDA receptors play a role in small blood vessel permeability
4. NMDA receptor antagonist ifenprodil can inhibit the excess glutamate related toxicity and decrease blood vessel permeability leading to less lung disease
