How COVID actively suppresses and evades your immune system [Part 2]
Part 2 looks at how mild and moderate #COVID infection reprograms white #blood cells (#monocytes) to reduce #innate #immune functions and how it evades the mucus layer in our #nose. 🧵1/

How #COVID actively suppresses and evades your immune system [Part 1]
This thread highlights multiple methods that the virus uses to help keep reinfecting people including MHC-I and interferon suppression, evasion of Natural Killer (NK) cells, and reprogramming of monocytes.🧵1/

COVID has been doing this to varying degrees since the beginning which further reinforces that a vaccine only policy is not enough to stop the cycle of sickness, long term disability, and death. 3/
#Monocytes at the Center of #SARS2 triggered inflammation & severe #Covid19
#SARS2 can cause acute respiratory distress & death in some patients. Although severe #COVID19 disease is linked to exuberant inflammation, how #SARS2 triggers inflammation is not understood. 1/

Monocytes & macrophages are the key sentinel cells that sense invasive infection to form inflammasomes that activate inflammatory cascade by secreting caspase-1 and gasdermin D, leading to inflammatory death (pyroptosis) & release of potent inflammatory mediators. 2/
~6% of monocytes in COVID patients are infected w/ SARS2
Monocyte infection depends on uptake of Ab-opsonized virus by FcÎł receptors
SARS2 begins to replicate in monocytes, but infection is aborted & infectious virus is not detected in infected monocyte culture supernatants. 3/

02/ Jean-Marc Sabatier (@SabatierJeanMa1), Directeur de Recherche au CNRS depuis 32 ans, PhD/HDR en Biochimie et Microbiologie, nous explique tout cela dans une vidéo (crowdbunker.com/v/Mqr69rxT) dont je résume les 42 premières minutes dans ce #thread.
03/ Le virus #SARS-CoV-2 s’attaque au #SRA (le système rénine-angiotensine), un de nos systèmes de régulation les plus importants, responsable des fonctions autonomes rénales, pulmonaires, cardiovasculaires, de l’#immunité innée et du #microbiote intestinal.
