Interesting that this involves a response similar to an immune response to a pathogen. I've read a couple articles about alternate theories of Alzheimer's linking it to an increased immune response in the brain.

Maybe that is the origin? Cells learning to counter different threats and communicating that information to other cells could be a plausible first step towards intelligence.

there’s no learning involved in the immune response in the brain. the brain is limited to the innate immune system, of which TLRs and their binding to conserved domains are basically the major component. there’s no adaptive immune system that does “learning” here (and by learning in the adaptive immune system we mean recombination of antibodies, presentation of contents of each cell on the surface of the cells for antibodies to try and bind to, and the preservation of cells that carry antibodies that bound to something successfully as memory cells to enable long term immunity)

This does not seem right. From what I recall, there is some sort of memory for the immune system.

you should reread what I wrote
