Unlabelled: Monoclonal antibodies to SARS-CoV-2 can offer prophylactic and therapeutic protection against severe disease, with particular utility for immunosuppressed and vulnerable populations. With the constant emergence of new variants, understanding the neutralizing potency of monoclonal antibodies to dynamic spike protein epitopes is crucial. We show that a set of VH1-24-derived N-terminal domain (NTD)-directed antibodies, isolated from a convalescent donor early in the pandemic, displayed remarkable neutralization resilience against many Omicron SARS-CoV-2 variants, including BA.

The functional role of enhancer-promoter configurations in transcription regulation remains poorly understood, despite the wide range of linear genomic distance and relative enhancer positioning observed in endogenous contexts. While canonical models suggest that enhancers operate independently of genomic position, technical limitations have obscured insights on transcriptional kinetics. Here, we employ single-cell MS2/MCP-based live imaging in embryos to systematically analyze transcriptional dynamics driven by sub-10kb enhancer-promoter arrangements.

Background/objectives: Patients with breast cancer who do not achieve a complete response to neoadjuvant chemotherapy (NAC) may benefit from intensified adjuvant systemic therapy. However, such treatment escalation is typically delayed until after tumour resection, which occurs several months into the treatment course. Quantitative ultrasound (QUS) can detect early microstructural changes in tumours and may enable timely identification of non-responders during NAC, allowing for earlier treatment intensification.

Mycobacterium tuberculosis (Mtb) remains the world's deadliest bacterial pathogen. There is an urgent medical need to develop new drugs that shorten the treatment duration to combat widespread multi-drug-resistant and extensive-drug-resistant Mtb. Here, we present a preclinical covalent compound, CMX410, that contains an aryl fluorosulfate (SuFEx) warhead and uniquely targets the acyltransferase domain of Pks13, an essential enzyme in cell-wall biosynthesis.

Globally, there is a movement to revive ancient Indigenous practices of traditional healing (TH) that utilize Land-based medicine and emphasize a wholistic approach to wellness. In Canada, the Truth and Reconciliation Commission's Call to Action urges the integration of Indigenous TH practices into healthcare systems. Drawing from anticolonial theory and Indigenous health geographies, this research examines traditional healing spaces (TH spaces) at the Centre for Addiction and Mental Health (CAMH) as an in-depth case study to understand how TH spaces transform institutional 'space' into Indigenous 'place' while challenging dominant biomedical paradigms.

Parkinson's disease is characterized by a period of non-motor symptoms, including gastrointestinal dysfunction, preceding motor deficits by several years to decades. This long prodrome is suggestive of peripheral immunity involvement in the initiation of disease. We previously developed a model system in PINK1 KO mice displaying PD-like motor symptoms at late stages following intestinal infections.

Olfactory activation of neuroendocrine pathways plays vital roles in many organisms for reproduction and survival. The importance of gonadotropin-releasing hormone (GnRH) neurons for reproduction is well-established but little is known about whether they can directly sense and transmit sex pheromone signals. We have uncovered the migration path and distribution pattern of a new GnRH neuronal population that fulfills this role.

Background And Objectives: Meningiomas are the most common primary tumor of the brain and may elicit hyperostosis of the adjacent bone. Whether hyperostosis is related to reactive changes of the overlying bone or by invasion of the tumor itself is unclear. In this article, we characterize the clinical and molecular differences of meningiomas with hyperostosis from those without hyperostosis.

Surge release of luteinizing hormone (Lh) from the pituitary is essential for fertility as it triggers ovulation. While secretoneurin (SN) is a phylogenetically conserved secretogranin-2-derived peptide that stimulates Lh, its role in ovulation has not been established. To directly compare periovulatory changes in the classical hormones to the emerging reproductive neuropeptides SNa and SNb, simultaneous mass spectrometry measurement of 9 peptides and 5 steroids was conducted in female zebrafish.

Mutations in SARS-CoV-2 variants of concern (VOCs) have expanded the viral host range beyond primates, and a few other mammals, to mice, affording the opportunity to exploit genetically diverse mouse panels to model the broad spectrum of responses to infection in patient populations. Here we surveyed responses to VOC infection in genetically diverse Collaborative Cross (CC) founder strains. Infection of wild-derived CC founder strains produced a broad range of viral burden, disease susceptibility and survival, whereas most other strains were resistant to disease despite measurable lung viral titers.
