#mecfs Great PhD research by @aryback.bsky.social. Thank you, Audrey!
aryback.bsky.social Audrey Ryback @aryback.bsky.social · Feb 17
Pleased to share this research from my PhD in @graemecowan.bsky.social's lab! We replicated existing evidence of moderately increased IGHV3-30 usage in B cells of patients with mild/moderate, but not severe ME. www.frontiersin.org/journals/imm...

From Australia:

Mapping the Complexity of ME/CFS: Evidence for Abnormal Energy Metabolism, Altered Immune Profile & Vascular Dysfunction

papers.ssrn.com/sol3/papers....

"These findings imply decreased ATP generation & the presence of energy stress within the immune cell population"

#MEcfs #CFS
Abstract Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a complex disorder with no known underlying mechanisms, diagnostic tools, or treatments. Multiple areas of dysfunction have been extensively studied, but rarely examined together. We recruited age- and sex-matched ME/CFS patients and healthy controls for a multi-modal study examining energy metabolism, immune profiles and plasma protein levels. Elevated levels of adenosine monophosphate (AMP) were detected in both plasma and immune cells. Additionally, immune cells showed higher levels of adenosine diphosphate (ADP) and a reduced adenosine triphosphate/adenosine diphosphate (ATP/ADP) ratio. These findings imply decreased ATP generation and the presence of energy stress within the immune cell population. Adaptive immune cell populations were skewed towards less mature effector subsets of CD4+, CD8+ and gd T cells, and proportions of CD1c+CD141-conventional DC type 2 (cDC2) and CD56lowCD16+ terminal natural killer (NK) cells were also reduced. Elevated levels of plasma proteins associated with thrombus formation and vascular reactivity may contribute to the endothelial dysfunction observed in ME/CFS patients. Using Classification and Regression Tree (CART) modelling, we identified variables from each mode of investigation with strong predictive potential for ME/CFS. Together, this study provides new insights into the somatic symptoms and underlying biology of ME/CFS.

Hate that it has come to this, but it's time to consider PubMed vulnerable to enshittification. My latest post @plos.org discusses the lines we need to fight to hold – and alternatives we can rely on internationally:

Quote from the letter:

"We express our dismay and concern at the rejection of our formal advice in 2024 to append an editorial note to the current version of the review stating that it is out of date and should not be used for clinical decision-making, as Cochrane has done for other reviews."

🔭 Supernova Remnant Cassiopeia A

Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their cores. After only a few million years for the most massive stars, the enriched material is blasted back into interstellar space where star formation can begin anew. The expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the supernova explosion that created this remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light 11,000 years to reach us. This sharp NIRCam image from the James Webb Space Telescope shows the still hot filaments and knots in the supernova remnant. The whitish, smoke-like outer shell of the expanding blast wave is about 20 light-years across. A series of light echoes from the massive star's cataclysmic explosion are also identified in Webb's detailed images of the surrounding interstellar medium.

1) There is some (cautious) excitement about this new ME/CFS paper that will soon be published.

It replicated abnormalities in B-cells that were found by 2 earlier studies, namely an increase in Immunoglobulin Heavy Variable IGHV3-30.
