The meninges host a distinct compartment of regulatory T cells that preserves brain homeostasis.

Our understanding of the meningeal immune system has recently burgeoned, particularly regarding how innate and adaptive effector cells are mobilized to meet brain challenges. However, information on how meningeal immunocytes guard brain homeostasis in healthy individuals remains limited. This study highlights the heterogeneous, polyfunctional regulatory T cell (T) compartment in the meninges.

Parental origin of transgene modulates amyloid-β plaque burden in the 5xFAD mouse model of Alzheimer's disease.

In Alzheimer's disease (AD) research, the 5xFAD mouse model is commonly used as a heterozygote crossed with other genetic models to study AD pathology. We investigated whether the parental origin of the 5xFAD transgene affects plaque deposition. Using quantitative light-sheet microscopy, we found that paternal inheritance of the transgene led to a 2-fold higher plaque burden compared with maternal inheritance, a finding consistent across multiple 5xFAD colonies.

Precipitated Withdrawal Induced by Prehospital Naloxone Administration.

Objectives: Buprenorphine is becoming a key component of prehospital management of opioid use disorder. It is unclear how many prehospital patients might be eligible for buprenorphine induction, as traditional induction requires that patients first have some degree of opioid withdrawal. The primary aim of this study was to quantify how many patients developed precipitated withdrawal after receiving prehospital naloxone for suspected overdose, as they could be candidates for prehospital buprenorphine.

Injury-induced Neuregulin-ErbB signaling from muscle mobilizes stem cells for whole-body regeneration in Acoels.

The activation of progenitor cells near wound sites is a common feature of regeneration across species, but the conserved signaling mechanisms responsible for this step in whole-body regeneration are still incompletely understood. The acoel undergoes whole-body regeneration using Piwi+ pluripotent adult stem cells (neoblasts) that accumulate at amputation sites early in the regeneration process. The EGFR signaling pathway has broad roles in controlling proliferation, migration, differentiation, and cell survival across metazoans.

Recommendations for Artificial Intelligence Application in Continued Process Verification.

This review paper explores the transformative impact of Artificial Intelligence (AI) on Continued Process Verification (CPV) in the biopharmaceutical industry. Originating from the CPV of the Future project, the study investigates the challenges and opportunities associated with integrating AI into CPV, focusing on real-time data analysis and proactive process adjustments. The paper highlights the importance of aligning AI solutions with regulatory standards and offers a set of comprehensive recommendations to bridge the gap between AI's potential and its practical, compliant, and safe application in pharmaceutical manufacturing.
