My chum reminds me: "The England India cricket series was a day longer than Liz Truss's premiership in duration (46 days from start to finish). Far more enjoyable, exciting, happy and socially more cohesive." Too right.

Membrane proteins ClcB, PtsI and YcaM mediate the bactericidal effects of colistin in Escherichia coli Bacteria can be killed very effectively by targeting their first line of protection. The cell membranes (outer and inner membranes) of Gram-negative bacteria are directly targeted by antibiotics, such as polymyxins, via electrostatic interactions with their lipopolysaccharide (LPS) fraction. The downstream effects - preceding the cell death - of the disruptions of the bacterial membranes upon the intercalation of these antibiotics are unknown. By screening a set of E. coli membrane protein knockouts, three membrane transporters were shown to mediate the growth-inhibitory effects of colistin. This was corroborated with growth assays on gain-of-function strains, cytotoxic assays and in vivo infections in an invertebrate animal model. This is first-time evidence that the disruption caused to membrane proteins, such as the chloride channel ClcB, the sugar transport system component PtsI and the hypothetical Glutamate:GABA antiporter YcaM, is part of the cytotoxic pathway that follows or is concomitant to the electrostatic intercalations of polymyxins with the Gram-negative bacteria membrane. ### Competing Interest Statement The authors have declared no competing interest.

A screenshot from the letter from ME researchers to funders over at https://psp-me.co.uk/campaign-strategic-approach-mecfs-research/.

It reads:
"MRC and NIHR have awarded ยฃ7.34m in ME/CFS research since 2013, including ยฃ3.2m to DecodeME (link). This is just ยฃ2.67 per person with ME (pwME) per year. Charities fund just under ยฃ2 per pwME per year (link). This compares with the UKโ€™s annual spend of ยฃ74 per person on health research (link). Despite being at least twice as prevalent, ME/CFS receives approximately 20-times less research funding than multiple sclerosis (link). ME/CFSโ€™s annual cost to the UK economy is at
least ยฃ3.3 billion (link); the cost of Long Covid to UK GDP is ยฃ1.5 billion annually (link)."

(Sorry, none of the links were actual links in the source document so I cannot share their sources with you)
(I also note they quote the ancient and incorrect prevalence figure of 250k in the same letter so presumably the amount per person is even less!)

It reads:

"A recent application to the highlight notice, having taken into account advice from academic experts, UKRI funders and PPI groups about the imperative to align and synergise molecular pathogenesis approaches across both ME/CFS and Long Covid, and from an internationally recognised team with multiple relevant, recent publications in Science, Nature and Lancet, was declined with one referee allocating a score of โ€˜1/6; poorโ€™. Another research team with a similar output profile has shelved all plans to work on ME/CFS after four attempts to obtain funding since 2020. Each application was revised in line with the feedback but then compromised by highly inappropriate reviews, two of which indicated that the reviewer had not read the grant (e.g., by criticizing experiments that were not proposed anywhere in the application), and one of which indicated that the reviewer had little or no relevant knowledge (e.g., by stating that there is a universal treatment for ME/CFS). Other reviews used earlier published research with conclusions based on highly questionable data to criticize the
validity of the approach, which had already pinpointed a molecular signature of ME/CFS. This work remains unpublished without funds needed to push it through to completion."

No prizes for guessing what the 'earlier published research with conclusions based on highly questionable data' is either.

This feels very systemic and also shows the levels of gaslighting from our government regarding their delivery plan - they've suggested they just need to encourage more research grant proposals and that will fix it. But when good grant proposals are being turned down like this by Wessely and co, that just won't cut it.
