Lewis‐X‐Containing Triterpenoid Saponins Inhibit DC‐SIGN‐ and L‐SIGN‐Mediated Transfer of HIV‐1 Infection

Chemistry – A European Journal, EarlyView.
The convergent synthesis of Lewis‐X‐containing betulinic acid and echinocystic acid saponins (1 and 2) is presented. The synthetic saponins were shown to inhibit, at the low micromolar range, the DC‐SIGN‐ and L‐SIGN‐mediated transfer of HIV‐1 infection to CD4‐positive cells, whereas free Lewis‐X, aglycones, and structurally similar triterpenoid ...

Single‐Cell Transcriptomic Analysis of the Immune Response to COVID‐19 and Tuberculosis Coinfection

Exploration, EarlyView.
Understanding the immunological basis for severe outcomes in COVID‐19/Tuberculosis coinfection is critical. Our single‐cell analysis identifies key drivers: profound lymphocyte loss through combined apoptosis and altered trafficking, excessive S100 protein‐mediated inflammation contributing to cytokine storms, and systemic immune dysfunction ...

Pathways to Progressive Disability in Multiple Sclerosis: The Role of Glial Cells in Chronic CNS Inflammation

Glia, EarlyView.
ABSTRACT Multiple sclerosis (MS) is the most common non‐infectious inflammatory CNS disease, characterized by progressive neurodegeneration and focal demyelinated lesions. Traditionally considered an autoimmune disease, MS is driven by the immune system's attack on CNS myelin, resulting in cumulative disability.

Prognosis and Phenotypes of Advanced Head and Neck Carcinoma Associated With Hypercalcemia

Head &Neck, EarlyView.
ABSTRACT Purpose Hypercalcemia is the most common metabolic disorder in cancer, affecting 10%–20% of patients with advanced malignancies, including squamous cell carcinoma of the head and neck (HNSCC), though its prognostic significance remains poorly studied.

Humoral Immune Response to Breakthrough Infection With SARS‐CoV‐2 Delta and Omicron Variants

iLABMED, EarlyView.
Patients with breakthrough infections of the Omicron variant exhibited significantly higher levels of neutralizing antibodies and IgG than those infected with the Delta variant. By contrast, Delta‐infected patients showed higher levels of IgM and IgA than Omicron‐infected patients.

Integrative cross‐tissue analysis unveils complement‐immunoglobulin augmentation and dysbiosis‐related fatty acid metabolic remodeling during mammalian aging

iMeta, EarlyView.
Our study provides a comprehensive multi‐omics profile of aging, integrating proteomic, metabolomic, and metagenomic analyses across diverse tissues and plasma. We identified the synergistic amplification of the circulating complement system and tissue‐wide immunoglobulin accumulation as key molecular drivers of inflammaging.

Soyasaponin and vertical microbial transmission: Maternal effect on the intestinal development and health of early chicks

iMeta, EarlyView.
This study investigates the vertical transmission of maternal microbiota in chickens and how it is modulated by maternal soyasaponin supplementation. Using a model spanning the reproductive tract, egg components, and developing chicks, we show that maternal gut and reproductive microbiota, including Bifidobacterium adolescentis (B.

Investigation on Klebsiella pneumoniae in the field of extracellular vesicles

Interdisciplinary Medicine, EarlyView.
The role of extracellular vesicles in the pathogenicity and antibiotic resistance, as well as treatment and prevention of Klebsiella pneumoniae. Abstract Klebsiella pneumoniae (KP), recognized for its pronounced antibiotic resistance, is a prevalent agent of nosocomial infections such as hospital‐acquired pneumonia.
