Many mechanisms by which stress mediates its effects within the central nervous system still remain unknown. Byun, Kim, Kim et al. find that early-life stress triggers corticosterone release to drive astrocyte-dependent synapse elimination and altered behavior. Thus, this work defines a steroid-sensitive astrocyte transcriptional circuit controlling behavior, highlighting how the study of CNS immunoregulation may shed light on behavior.

Article Synopsis
  • Astrocytes help clear proteins and waste in the brain using aquaporin-4 (AQP4), which can be disrupted in stress-related disorders.
  • Dexamethasone (Dexa), a glucocorticoid used to model stress, was found to reduce the activity of AQP4 and its associated proteins in astrocytes, leading to impaired protein clearance.
  • The study suggests that blocking adenosine A receptors (AR) can restore AQP4 function and clearance, indicating a potential therapeutic strategy to address neurological disorders linked to stress and protein accumulation.

We present novel fluorescent cholesteryl probes (CNDs) with a modular design based on the solvatochromic 1,8-phthalimide scaffold. We have explored how different modules-linkers and head groups-affect the ability of these probes to integrate into lipid membranes and how they distribute intracellularly in mouse astrocytes and fibroblasts targeting lysosomes and lipid droplets. Each compound was assessed for its solvatochromic behavior in organic solvents and model membranes.

Huntington's disease (HD) is a debilitating neurodegenerative disorder characterized by severe motor deficits, cognitive decline and psychiatric disturbances. An early and significant morphological hallmark of HD is the activation of astrocytes triggered by mutant huntingtin, leading to the release of inflammatory mediators. Fingolimod (FTY), an FDA-approved sphingosine-1-phosphate (S1P) receptor agonist is used to treat multiple sclerosis (MS), a neuroinflammatory disease, and has shown therapeutic promise in other neurological conditions.

Objective: Autoimmune glial fibrillary acidic protein astrocytopathy (GFAP-A) is a novel steroid sensitive autoimmune disease, without a diagnostic consensus. The purpose of this study was to improve early GFAP-A diagnosis by increasing awareness of key clinical characteristics and imaging manifestations.

Methods: Medical records of 13 patients with anti-GFAP antibodies in serum or cerebrospinal fluid (CSF) were reviewed for cross-sectional and longitudinal analysis of clinical and magnetic resonance imaging (MRI) findings.

Article Synopsis
  • Glioblastoma multiforme (GBM) is a highly aggressive brain tumor categorized as Grade 4 by the WHO, with established risk factors including genetic syndromes, body mass index, and certain medications.
  • Vascular issues such as thrombosis are common in GBM, and podoplanin (PDPN) plays a significant role in tumor progression by enhancing platelet activity and cancer cell metastasis.
  • PDPN is suggested as an independent prognostic factor for GBM, as its expression is linked to worse outcomes, with recent studies indicating its involvement in the development of more aggressive cancer stem cells.
