    Full Title:
    Using Plasma Autoantibodies of Central Nervous System Proteins to Distinguish Veterans with Gulf War Illness from Healthy and Symptomatic Controls

    Gulf War Illness the main focus of the study but they had a control group of 50 people with ME/CFS

    Question 1: what is GFAP?
    Question 2: what relevance would elevated GFAP autoantibodies have & could that really be a biomarker (if the finding stacks up)?

    Have only read the abstracts of the following.

    So it looks like:
    1. GFAP are rather important to health.
    2. Autoantibodies to GFAP are elevated in at least some other conditions and are already being used as a biomarker for a type of autoimmune astrocytopathy - this would seem to complicate their use as biomarker for ME?
    3. Autoantibodies to GFAP are not causing any problems themselves but are a marker of "immune inflammation" (whatever that is but given it implicates astrocytes maybe it's another take on the nebulous "neuroinflammation"?).

    Generally speaking, GWI sounds like it's mostly triggered by exposure to chemicals, whereas ME/CFS seems mostly triggered by infections, though it seems like there are some cases where the opposite has been true.

    This makes me think that the thing that they may have in common is that something (not necessarily the same thing) is crossing the blood brain barrier and the illnesses are a result of the brain's immune system reacting to that.

    Dr. Komaroff mentioned this possibility years ago when describing a 2005 study as showing:

    He was referring to this 2005 study by James Baraniuk, et al.

    This makes a lot of sense. The Countess of Mar’s trigger was chemicals too, sheep dip, I believe.
