Integrative Multi-Omics Analysis Reveals Biomarkers of Severe Systemic Allergy to Honeybee Venom and Olive Pollen

This study demonstrates that integrative multi-omics profiling combined with functional immune assays effectively distinguishes mild from severe systemic allergy phenotypes in both honeybee venom and olive pollen patients by revealing distinct, allergen-specific molecular and cellular signatures associated with disease severity.

Glutamine stress promotes metastatic potential via hexosamine biosynthetic pathway activity in KRAS/STK11-mutant lung adenocarcinoma

This study reveals that in KRAS/STK11-mutant lung adenocarcinoma, glutamine deprivation triggers a metabolic rewiring that enhances hexosamine biosynthetic pathway flux, thereby promoting metastatic traits and challenging the therapeutic efficacy of glutamine deprivation strategies.

Alveolar epithelial cell senescence predominates over macrophage senescence in driving pulmonary fibrosis

This study demonstrates that senescent type II alveolar epithelial cells, rather than macrophages, are the primary drivers of pulmonary fibrosis progression through the secretion of GDF15, highlighting a potential therapeutic target for idiopathic pulmonary fibrosis.

Host plant phenology and hypergaller-induced endogalls shape the gall life cycle and structure in Myrcia ovata Cambess

This study reveals that the year-round leaf phenology of *Myrcia ovata* facilitates continuous gall induction by *Myrciamyia maricaensis*, while inquiline hypergallers subsequently restructure these primary galls through tissue hyperplasia and resource hijacking, thereby altering the developmental dynamics and life cycle of this multitrophic system.

Quantitative adaptor heterogeneity sets single-cell thresholds for innate immune activation and attenuation

This study reveals that pre-existing heterogeneity in MyD88 abundance within macrophages determines single-cell thresholds for innate immune activation, where strong agonists drive robust signaling and feedback termination while weak agonists lead to persistent low-output signaling, a mechanism of incomplete activation-feedback coupling that correlates with chronic inflammatory diseases like Alzheimer's.

Integrated B and T Cell Repertoire Analysis Reveals Organized but Heterogeneous Adaptive Immunity in Chronic Experimental Stroke

This study demonstrates that chronic post-stroke adaptive immunity is characterized by a reproducible, organized, yet heterogeneous clonal expansion of both B and T cells within the infarct, revealing a structured multi-lineage immune response across diverse experimental conditions.

A Physiology Based Three Layer Diffusion Reaction Model For In Vitro To In Vivo Translation Of Intravesical Mitomycin C Exposure In The Human Urinary Bladder Wall

This study presents a physiology-based three-layer diffusion-reaction model parameterized solely by human in vitro data that successfully predicts clinical intravesical mitomycin C concentrations in the urothelium and lamina propria, offering a scientific basis for optimizing treatment regimens based on tissue exposure rather than empirical urinary metrics.

Identification of longevity strains of Saccharomyces cerevisiae under high-glucose conditions

This study identifies and characterizes multiple longevity-adapted *Saccharomyces cerevisiae* strains evolved under high-glucose stress, revealing that while distinct lineages employ diverse transcriptional strategies, they converge on a shared metabolic remodeling of the tryptophan-kynurenine pathway and NAD+ networks to enhance survival and robustness.
