AI Article Synopsis

  • High-resolution omics techniques, especially single-cell and spatial transcriptomics, are improving our understanding of gliovascular cell diversity and age-related changes that lead to neurodegeneration.
  • The review emphasizes new molecular features of neurovascular and glial cells identified through omic profiling, focusing on those with functional significance and differences between humans and mice, particularly related to aging and inflammation in neurodegenerative diseases.
  • It also discusses how omic profiling can aid in discovering biomarkers and developing therapies to modify disease progression in neurodegenerative conditions.

Article Abstract

High-resolution omics, particularly single-cell and spatial transcriptomic profiling, are rapidly enhancing our comprehension of the normal molecular diversity of gliovascular cells, as well as their age-related changes that contribute to neurodegeneration. With more omic profiling studies being conducted, it is becoming increasingly essential to synthesise valuable information from the rapidly accumulating findings. In this review, we present an overview of the molecular features of neurovascular and glial cells that have been recently discovered through omic profiling, with a focus on those that have potentially significant functional implications and/or show cross-species differences between human and mouse, and that are linked to vascular deficits and inflammatory pathways in ageing and neurodegenerative disorders. Additionally, we highlight the translational applications of omic profiling, and discuss omic-based strategies to accelerate biomarker discovery and facilitate disease course-modifying therapeutics development for neurodegenerative conditions.

Patients with metastatic pancreatic ductal adenocarcinoma survive longer if disease spreads to the lung but not the liver. Here we generated overlapping, multi-omic datasets to identify molecular and cellular features that distinguish patients whose disease develops liver metastasis (liver cohort) from those whose disease develops lung metastasis without liver metastases (lung cohort). Lung cohort patients survived longer than liver cohort patients, despite sharing the same tumor subtype.

Background: Younger‐onset neurocognitive symptoms result from a heterogenous group of neurological and psychiatric disorders which present a diagnostic challenge. To identify such factors, we analysed the BeYOND (Biomarkers in Younger‐Onset Neurocognitive Disorders) cohort, a study of individuals less than 65 years old presenting with neurocognitive symptoms for a clinical diagnosis and who have undergone cognitive and biomarker analyses.

Method: 65 participants were recruited during their index presentation to the Royal Melbourne Hospital Neuropsychiatry Centre, a tertiary specialist service in Melbourne, Australia.

Background: Autophagy‐lysosomal pathway (ALP) efficiency declines Alzheimer’s disease (AD). In AD mouse models expressing a fluorescent autophagy and pH probe, autolysosomes pH elevation, resulting from deficient v‐ATPase activity, causes autophagy substrates, including Aβ and APP‐βCTF, to build up selectively within autolysosomes before extracellular amyloid deposits. In the most compromised but still intact neurons, massive numbers of Aβ‐positive autolysosomes pack into huge petal‐like blebs bulging out from the perikaryal membrane (PANTHOS).

Background: Space-induced plant mutagenesis, driven by cosmic radiation, offers a promising approach for the selective breeding of new plant varieties. By leveraging the unique environment of outer space, we successfully induced mutagenesis in 'Deqin' alfalfa and obtained a fast-growing mutant. However, the molecular mechanisms underlying its rapid growth remain poorly unexplored.
