Actually, this microglia has been the most fascinating thing for me in the last two years. To make things more complicated, there are two kinds of it. The one that sits in the tissue as a watchdog against pathogens and injury is generally deleterious; the only thing it can do is starting inflammation as a "whistleblower" and scavenger of sorts. The second one that actually does repair comes from the bone marrow, possible recruited by this inflammation. Amazing stuff. Also, mice without immunity seem to be significantly more stupid than wild type!
Franklin, I am impressed about your knowledge of biology!
