Discussed in this episode: A newly-published study in Nature Neuroscience points to a likely mechanism by which Long Covid produces neurological symptoms like brain fog: disruption of the blood-brain barrier Because of fundraising at KPFA, we’ll only be taking questions via email for the next week (the station needs its phone lines free for people … Continued

Discussed in this episode: A new article in the journal Cell finds Long Covid associated with reduced levels of serotonin circulating in the bloodstream. (The authors’ explanation: the persistent presence of the virus, and/or its fragments, causes the body to crank out more type I interferons. The interferons cause  inflammation in the gut that reduces uptake … Continued

Discussed in this episode: COVID hospitalizations continue to trend up, nearly doubling rates from mid-summer. (That’s a large increase from a low baseline: in most of the country, hospitalization rates are still what the CDC considers “low.”) A new observational study using patient data from Stockholm suggests the percent of COVID cases that result in … Continued

Discussed in this episode: A new paper in Science Translational Medicine draws results from animal experiments, human samples, and human autopsies to suggest a mechanism for some cases of Long Covid: the virus binds to a protein on our cells’ mitochondria and can enduringly alter their function.

Discussed in this episode: New research published in Nature examined if people who got infected without showing symptoms had something in common genetically. They did: a mutation on the  HLA-B (that’s short for Human Leukocyte Antigen) gene. In the laboratory, T-cell samples collected from those people *before* infection reacted strongly to SARS-COV2, suggesting the mutation helps … Continued
