#location location location: thrilled to share our work @CellCellPress! #interferons dictate #COVID19 severity! Specific #IFNs are produced along the #airways in response to #SARSCoV2 and drive protective or detrimental #transcriptional programs! 1/7 doi.org/10.1016/j.cell…
IFNs are driven by high #viral #loads, suggesting that viral recognition is only achieved when #SARSCoV2 reaches a certain threshold! Efficient induction of protective IFNs is preferentially achieved by younger patients, further explaining susceptibility of elders to #COVID19 2/7
#IFNL1 & #IFNL3 characterize mild illness & drive potent anti-#SARSCoV2 #ISGs in the upper #airways. Severe patients show #typeI IFN & #IFNL2 along the respiratory tract but lack ISGs, dampen cell proliferation programs associated to #repair and boost #apoptotic #p53 pathways 3/7

I want to talk about 2 papers that highlight the role of mitochondria in what are likely the progression of symptoms assoc with #COVID19. Note these papers are not about #covid but highlight important pathways. 1/
1st paper - Intracellular ATP is req. 4 #mitochondrial #apoptotic pathways rat #cardiac #myocytes ncbi.nlm.nih.gov/pubmed/12909326 2/
Key findings: apoptosis and necrosis are part of the same pathway, initiated by same mito sequences but are distinguished by time and severity, where the delimiting factor is available intracellular #ATP. 3/
