Es gibt zwei neue CFS Studien die interessant sind.
Hat jemand Kraft in deutscher Sprache ein wenig zusammenzufassen.
Mir gehts nicht gut genug.
Lower frequency of IL-17F sequence variant (His161Arg) in chronic
fatigue syndrome patients

Chronic fatigue syndrome (CFS) is characterized by immune
dysfunctions including chronic immune activation, inflammation, and
alteration of cytokine profiles.
T helper 17 (Th17) cells belong to a recently identified subset of T
helper cells, with crucial regulatory function in inflammatory and
autoimmune processes. Th17 cells are implicated in allergic
inflammation, intestinal diseases, central nervous system
inflammation, disorders that may all contribute to the
pathophysiology of CFS. IL-17F is one of the pro-inflammatory
cytokines secreted by Th17 cells.
We investigated the association between CFS and the frequency of
rs763780, a C/T genetic polymorphism leading to His161Arg
substitution in the IL-17F protein. The His161Arg variant (C allele)
antagonizes the pro-inflammatory effects of the wild-type IL-17F. A
significantly lower frequency of the C allele was observed in the CFS
population, suggesting that the His161Arg variant may confer
protection against the disease.
These results suggest a role of Th17 cells in the pathogenesis of CFS.

This work investigates the significance of changes in association
patterns linking indicators of neuroendocrine and immune activity in
patients with chronic fatigue syndrome (CFS).
Gene sets preferentially expressed in specific immune cell isolates
were integrated with neuroendocrine data from a large population-
based study. Co-expression patterns linking immune cell activity with
hypothalamic-pituitary-adrenal (HPA), thyroidal (HPT) and gonadal
(HPG) axis status were computed using mutual information criteria.
Networks in control and CFS subjects were compared globally in terms
of a weighted graph edit distance. Local re-modeling of node
connectivity was quantified by node degree and eigenvector centrality
measures. Results indicate statistically significant differences
between CFS and control networks determined mainly by re-modeling
around pituitary and thyroid nodes as well as an emergent immune sub-
network.
Findings align with known mechanisms of chronic inflammation and
support possible immune-mediated loss of thyroid function in CFS
exacerbated by blunted HPA axis responsiveness.
