Medical Express: Researchers identify key role of immune cells in brain infection (2020)

In mice.

An interesting bit from the very technical and way above my head paper the above is based on: immune cells get through the BBB into the brain even as the virus is being cleared by antiviral treatment, and the timing with which those immune cells arrive is awfully similar to my PEM. Most probably a coincidence, I don't have viral encephalitis nor am I a mouse, but just couldn't help noticing.

I did a very quick google of the 2 molecules investigated in the paper in relation to ME.
Didn't find anything for CXCR2. But CXCL1 has cropped up in past studies (have only glanced at the abstracts):
