    I have no idea what this means in terms of understanding ME, and it's a tiny study, but the differences found in quantity and size of EV's is surprisingly different. Maybe a biomarker? Early days, of course.

    Dr. Maureen Hanson states in this talk that she will be doing a study that examines extracellular vesicles:

    Thanks for that @Diwi9. Really interesting - they are going to look at EV's as part of their 2day CPET study of all sorts of things in blood and brains before and after exercise challenge.

    Since I'd never heard of EV's, I did a quick google and see that they are being studied as markers in cancer, aging and other things. So perhaps it's more of a general "something wrong in the body" marker than an ME/CFS biomarker, but it still adds to the picture of the physical debility we have and might help measure if some intervention brings improvement or deterioration.

    A post by @strategist in November 2017 - Watanabe's team is on to EV's too.

    Watanabe et al. have received funding to conduct a 120 participants PET brain imaging study.

    The primary outcome:
    The level of brain positive inflammation dected by positron emission tomography (PET), [F18]DPA-714

    Secondary outcomes:
    Oxidative stress level, Anti-oxidant activity, Metabolome, Proteome, Cytokines, Extracellular vesicles, Clinical test (CRP, cholesterol, etc.), CD antibody, Autonomic nervous system, Questionnaires for fatigue, depression and various symptoms, Arithmetic task, Sleep-wake cycle, Performance status for fatigue

    Now this is interesting. I have long wondered if the extra-cellular matrix was playing a role.
