Pathognomonic microglial nodules and T cell infiltration are present in COVID-19 brains
Altered microglia-T cell interactions correlate with systemic measures of inflammation

Many patients with SARS-CoV-2 infection develop neurological signs and symptoms, though, to date, little evidence exists that primary infection of the brain is a significant contributing factor. We present the clinical, neuropathological, and molecular findings...
An interesting read given the past TSPO-PET neuroinflammation studies on ME using first generation [11C]PK-11195 and now more recently second generation [11C]DPA-713, the pros/cons and limitations of these radioligands, and the development of novel third generation ligands.
Recent Developments...

This is a story about neurology that I thought might be of general interest.
I found this on CBC's Quirks and Quarks:
Before he was born, his parents knew their boy was in trouble. That was clear from what their doctors' saw in their baby's ultrasound. And tragically, the boy died when he was...
I took Valcyte for 2 1/2 years. I had suspected infectious onset based on initial fever and symptoms, as well as chronically very high EBV, CMV, HHV-6 antibody titers. Valcyte didn’t have any effect on my ME, though I was working full-time and push-crashing all the time.
Valcyte also had this...
Possibly relevant to ME given the potential involvement of both microglia in the brain and the microbiome in the illness.
