Article Synopsis
  • - Gulf War Illness (GWI) is a complex condition impacting 25-32% of Gulf War veterans, presenting symptoms like cognitive issues, fatigue, and gastrointestinal problems, believed to stem from toxic exposures and stress during deployment.
  • - A study created a mouse model to investigate whether exposure to the pesticide permethrin, followed by stress, could trigger depression-like behaviors and microglial activation in the brain.
  • - Using advanced single-cell RNA sequencing, researchers found significant changes in microglial populations related to the pathways affecting neuron development and communication, highlighting the potential link between permethrin exposure, stress, and psychiatric symptoms.

Introduction: The function of the vocal folds (VFs) is determined by the phenotype, abundance, and distribution of differentiated cells within specific microenvironments. Identifying this histologic framework is crucial in understanding laryngeal disease. A paucity of studies investigating VF cellular heterogeneity has been undertaken.

Article Synopsis
  • Despite the notable advancements in immunotherapy for cancer, only a small percentage (less than 20%) show lasting responses to immune checkpoint blockade, leading researchers to consider combination therapies that target multiple immune evasion strategies.
  • Researchers analyzed data from over 1,000 tumors across ten cancers to identify seven distinct immune subtypes, examining their unique genomic, epigenetic, transcriptomic, and proteomic characteristics.
  • By investigating kinase activities linked to these immune subtypes, the study uncovered potential therapeutic targets that could improve future immunotherapy approaches and precision medicine.

We introduce UniCell: Deconvolve Base (UCDBase), a pre-trained, interpretable, deep learning model to deconvolve cell type fractions and predict cell identity across Spatial, bulk-RNA-Seq, and scRNA-Seq datasets without contextualized reference data. UCD is trained on 10 million pseudo-mixtures from a fully-integrated scRNA-Seq training database comprising over 28 million annotated single cells spanning 840 unique cell types from 898 studies. We show that our UCDBase and transfer-learning models achieve comparable or superior performance on in-silico mixture deconvolution to existing, reference-based, state-of-the-art methods.

Cell lines are one of the most frequently implemented model systems in life sciences research as they provide reproducible high throughput testing. Differentiation of cell cultures varies by line and, in some cases, can result in functional modifications within a population. Although research is increasingly dependent on these model systems, the heterogeneity within cell lines has not been thoroughly investigated.
