More indication that immune activation and trafficking to brain, not viral entry, predominant cause of Covid cognitive issues.
Noted to match processes in AD and PD. Good news for patients and Leronlimab efficacy.
“While a systematic analysis yields no molecular traces of SARS-CoV-2 in the brain, we observe broad cellular perturbations which predict that choroid plexus barrier cells sense and relay peripheral inflammation into the brain and show that peripheral T cells infiltrate the parenchyma. We discover COVID-19 disease-associated microglia and astrocyte subpopulations that share features with pathological cell states reported in human neurodegenerative disease4–6. Synaptic signaling of upper-layer excitatory neurons—evolutionarily expanded in humans7 and linked to cognitive function8—are preferentially affected in COVID-19. Across cell types, COVID-19 perturbations overlap with those in chronic brain disorders and reside in genetic variants associated with cognition, schizophrenia, and depression. Our findings and public dataset provide a molecular framework to understand COVID-19 related neurological disease observed now and which may emerge later.”
