    Friday 6th Sept, I will be having another of my video Q&As, this time with Dr Karl Morten of University of Oxford. So post your questions for him below and I will ask him as many as possible. Questions posted up until end of Monday 2nd Sept will be considered.

    If you need reminding of Karl and his work, click here for his University of Oxford profile, and here for his Researchgate profile.

    For forum threads that are relevant:

    Click here for my thread reporting as a patient representative with his collaborative research group (includes discussion of his rejected application to the MRC for funding).

    Click here for the thread on the paper that attempted to validate the findings of the mito function test that Sarah Myhill uses. (Karl and Julia Newton were joint authors).

    Click here for the thread on his talk in New Zealand (includes link to YouTube video of the talk).

    Click here for the thread on Simon McGrath's blog that discussed the research from various groups, including Karl's, that have found evidence for "something" in the blood of patients.

    ETA: To view our previous Q&As with other researchers see https://www.youtube.com/playlist?list=PLueHKJtiq09dtfqte4pcFkEbFaeWSQqRD

    Q1. In the NZ presentation Karl Morten showed a 6 fold increase in Glutamate and a reduction in Glutamine. What needs to be done to validate this possible key finding?

    Q2.How do Glutamate levels in the blood correlate to Glutamate levels in the brain?


    Elevated Glutamate is thought to be involved in Catanonia (Wikipedia) and Catatonia symptoms share many elements with very severe ME.

    Some quotes from Wikipedia:


    Here is a recent Twitter thread that is worth a read on Catatonia by Dr. Mark Guthridge from Australia (tweets a lot about ME/CFS)

    Q3. In the NZ presentation 2 unidentified VIP metabolites were significantly elevated in a subset of patients. What work has been done to identify those metabolites and to verify in a additional small cohort?

    Q4. Is Karl Morten in communication with other groups doing metabolite work such as Lipkin, Naviaux, Davis, Hanson to dig deeper into these results. For example could Metabolon/Others program their Mass spec to look for these particular unidentified metabolites in other ME/CFS cohorts as those samples are processed?

    Q5. The oxygen consumption plasma swap that Karl Morten reported on was fascinating, corroborating others findings that something in the plasma is inhibiting the energy pathways. Could Karl elaborate on ideas/experiments he could perform given adequate funding to take this further to try and narrow down the causes of the changes. What needs to be done.

    EDIT: In the Stanford nanoneedle paper published this year they described the procedure for applying a salt solution to the cells plus plasma and observing a membrane impedance change in cells with ME/CFS plasma. It would be very interesting to retry your experiment with the addition of the same concentration of salt solution to see what you observe with oxygen consumption.

    Q6. Paul Fisher presented detailed work into Mitochondrial function in ME/CFS plasma cells at the Australia conference hosted by Emerge. Has Karl had a chance to brainstorm and discuss findings with Paul why cells seem to be in a high energy overdrive but then the end output seems reduced - both Karl and Paul are well respected Mitochondrial experts.

    Q7. How much beer money would it take to visit Accumen Labs in Devon and jointly perform an experiment with John McLaren-Howard to resolve the differences on the Mitochondrial Function test so that both parties can be satisfied. I'm sure Norman Booth would have welcomed this. Combine with a long weekend Vacation perhaps?

    Q8. In your NZ presentation and in the Tomas et al Mitochondrial Function test paper, you expressed the importance and relevance of timely processing of blood drawn from study participants for some studies. If I remember right you showed an example of substrate exhaustion when blood is left in the tube for an extended time.

    For the studies you would like to perform, would you be able to use the UK ME Biobank samples, or would you have specific blood draw process requirements needing processing on site at your lab? How could patients help you with this if needed?

    Q9. I'm a sucker for personal stories. He touched on this in the NZ presentation.. I'm sure many of us would like to understand his path to becoming involved in ME/CFS and why and how he wants to make a difference.

    I am very interested to hear what he thinks about Fisher's findings.

    I would like to know what other illnesses have similar metabolite profiles, and whether he feels confident to say anything about metabolism in ME/CFS yet.

    How far away is a diagnostic test? Even one that merely shows something is wrong and is usable in practice by physicians would be a nice step forward.

    Seconded.
    Plus should we be seeking diagnostic or informative testing (lupus is (often) diagnosed by test panels). IS atest invalid just because it is not diagnostic?
    Can we see Mc's claims as to integrity of his procedues taken seriously (incl possibility of refutation, of course). Is it good enough to just claim that timing issues must have played a role?
    What does KM have to say about alledged improvements in mito score and clinical improvements after interventions?

    You found that cellular phenylalanine is increased in ME patients.

    Do you have any hypothesis on why this may be happening ?

    Dr. Phair is studying Metabolic Traps . One of them could be the Tyrosine trap in which tyrosine hydroxylase may be substrate inhibited . Any thoughts on this and how this could be related to your findings ?
