Holy shit. Microglial cells are the immune cells in the brain. I guess there could be other ones but that’s something microglial cells do. As well as the normal glial cell process of feeding the neurons lactate.

This might help someone…….somewhere!

Summary: COVID-19 infection causes microglia to excessively engulf synaptic structures and the upregulation of factors involved in phagocytosis.

Researchers at Karolinska Institutet have in a new study used cellular reprogramming to create human three-dimensional brain models and infected these models with SARS-CoV-2.

In infected models, the brain immune cells excessively eliminated synapses and acquired a gene expression pattern mimicking what has been observed in neurodegenerative disorders.

The findings could help to identify new treatments against persistent cognitive symptoms after a COVID-19 infection.
