Gut microbiota (GM) alterations have been implicated in autism spectrum disorder (ASD), yet the specific functional architecture remains elusive. Here, employing multi-omics approaches, we investigate stool samples from two distinct cohorts comprising 203 children with mild ASD or typical development. In our screening cohort, regression-based analysis for metabolomic profiling identifies an elevated γ-aminobutyric acid (GABA) to glutamate (Glu) ratio as a metabolic signature of ASD, independent of age and gender.

Article Synopsis
  • Neuroinflammation involves activating glial cells and significantly influences cognitive impairment in central nervous system disorders, although the details of these mechanisms are not fully understood.
  • The study investigated the role of perineuronal nets (PNNs) and the ApoE gene in this process, using a model of neuroinflammation induced by lipopolysaccharides (LPS) while assessing cognitive function through various tests.
  • Results indicated that LPS treatment led to cognitive deficits due to reduced PNNs and altered neural oscillations, highlighting that microglial phagocytosis of PNNs, influenced by ApoE, is crucial to understanding neuroinflammation-related cognitive decline.

Unfractionated heparin (UFH) is commonly used as an anticoagulant in sepsis treatment and has recently been found to have non-anticoagulant effects, but underlying mechanisms remain unclear. This retrospective clinical data showed that UFH has significant protective effects in sepsis compared to low-molecular-weight heparin and enoxaparin, indicating potential benefits of its non-anticoagulant properties. Recombinant protein chip screening, surface plasmon resonance, and molecular docking data demonstrated that UFH specifically bound to the cytoplasmic Drp1 protein through its zone 2 non-anticoagulant segment.

Surgical excision of the primary tumor represents the most frequent and curative procedure for solid malignancies. Compelling evidence suggests that, despite its beneficial effects, surgery may impair immunosurveillance by triggering an immunosuppressive inflammatory stress response and favor recurrence by stimulating minimal residual disease. In addition, many factors interfere with the immune effectors before and after cancer procedures, such as malnutrition, anemia, or subsequent transfusion.
