Default Microglia and Alzheimer's

A couple-three years ago I became interested in studying up on microglia, wrote a little paper about their role in pain for a Canadian ortho newsletter, read whole books about them. The more I read about them the more I did not like them, but more to the point, the more I realized that the body, even inside the brain, is an ecosystem in balance that can tip this way or that. Microglia (which are not ectodermally derived like the other glia - rather they come from very very early mesodermal stock, like the rest of the immune system) seem like little scavengers, but here, in the case of Alzheimer's, it looks like they can be predatory too.
This news story is about how they are attracted to fractalkine (which is something stressed neurons secrete) and about how plugging up fractalkine receptors (not letting microglia catch the scent) will keep them from heading over to stressed neurons and killing them. The neurons have a better shot at recovering if the microglia are held at bay. I think this sounds quite hopeful. I'm putting it here, Barrett, because I know this is something that you concern yourself about.

Full text article, free access.

Microglial Cx3cr1 knockout prevents neuron loss in a mouse model of Alzheimer's disease.

A blogpost about it, "Who isn't afraid of Altzheimer's?"
