>#LongCOVID is associated with reduced circulating #serotonin levels
>Serotonin depletion is driven by viral #RNA-induced type I #interferons (IFNs)
>IFNs reduce serotonin through diminished# tryptophan uptake and #hypercoagulability
>Peripheral serotonin deficiency impairs #cognition via reduced #vagal signaling
