Une étude ne trouve aucune inflammation cérébrale généralisée liée au Covid long

Des chercheurs finlandais n'ont trouvé aucune preuve d'inflammation cérébrale généralisée chez les personnes souffrant de Covid long. Les résultats associent plutôt des symptômes plus sévères à une activité accrue dans les zones du cerveau impliquées dans les émotions et la mémoire.

Une équipe de l'Université de Turku a examiné 14 personnes atteintes de Covid long à l'aide de TEP et d'IRM. Ils ont comparé les résultats avec les scanners de 11 volontaires sains et de 13 patients atteints de sclérose en plaques. Aucune différence significative au niveau des marqueurs d'inflammation cérébrale n'est apparue entre le groupe Covid long et les témoins sains. Les patients atteints de Covid long présentaient également beaucoup moins d'inflammation de la substance blanche que le groupe atteint de sclérose en plaques.

Researchers analyzing immune cells from people with long COVID have identified a distinct molecular state in CD14+ monocytes—labeled “LC-Mo”—that was more prevalent among patients whose initial COVID-19 illness was mild to moderate and that tracked with reported fatigue and respiratory symptoms, along with higher levels of inflammatory signaling molecules in blood plasma.

New research indicates that severe cases of COVID-19 or influenza can alter lung immune cells, potentially increasing cancer risk months or years afterward. The study, conducted by scientists at the University of Virginia, highlights the role of chronic inflammation in this process and emphasizes vaccination as a preventive measure. Findings suggest closer monitoring for affected patients to enable early detection.

Researchers at the University of California, San Francisco have identified how aging lungs contribute to severe flu and COVID-19 outcomes in older adults. Their study shows that lung fibroblasts trigger excessive inflammation, forming damaging clusters of immune cells. The findings, published in Immunity on March 27, suggest potential new treatments.

Scientists at the University of Southern California have found experimental compounds that may reduce harmful brain inflammation associated with Alzheimer’s disease. The work focuses on the enzyme cPLA2 and people who carry the high-risk APOE4 gene.

A study of 440 participants from the Women’s Interagency HIV Study found that accelerated epigenetic aging in monocytes—an immune cell type—tracked more closely with emotional and cognitive depression symptoms such as hopelessness and loss of pleasure than with physical symptoms like fatigue. The work, published in The Journals of Gerontology: Series A, adds evidence that cell-type-specific aging measures could contribute to future biological tools to complement symptom-based depression screening, though researchers say more validation is needed before clinical use.
