Weissella koreensis regulates mitochondrial protective genes and innate immune genes to enhance anti-bacterial immunity

Probiotics are widely recognized for their ability to promote gut health, modulate immunity, and reduce oxidative stress. As an emerging probiotic within the genus Weissella, Weissella koreensis (WK) exhibits promising immunomodulatory potential. Recen…

Integrating multi-omics and machine learning to reveal IL1R2-driven macrophage-fibroblast spatial interactions in polycyclic aromatic hydrocarbon-induced pulmonary fibrosis

BackgroundPolycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental toxicants, yet the toxicological mechanisms by which they induce idiopathic pulmonary fibrosis (IPF) remain poorly understood. This study aims to systematically elucidate th…

Brentuximab vedotin plus CHP-like versus CHOEP regimen for the first-line treatment of PTCL patients: a multi-center propensity-matched retrospective study

IntroductionThe optimal frontline treatment option for Peripheral T-cell lymphomas (PTCLs) has not been completely defined.MethodsTo compare the efficacy and safety of brentuximab vedotin (BV) combined with CHP-like regimen (cyclophosphamide, an anthra…

Inducible and reversible in vivo protein degradation reveals T cell-intrinsic regulatory function of SHP-1

Scientific problemStudying the acute, cell-intrinsic functions of signaling proteins in T cells has long been challenging. Existing constitutive or inducible gene deletion cannot overcome developmental adaptation that obscures true phenotypes. Similarl…

Integrating proteomics to map immune landscape and protein biomarkers for risk stratification in childhood Langerhans cell histiocytosis

BackgroundLangerhans cell histiocytosis (LCH) is a rare pediatric disease with marked clinical heterogeneity. Current risk stratification relies on the extent of organ involvement and risk-organ status, yet reliable protein biomarkers for distinguishin…

Large-scale plasma proteomics identifies proteins and pathways associated with incident interstitial lung disease

ObjectiveReliable biomarkers for early interstitial lung disease (ILD) risk stratification are limited; therefore, we aimed to identify prediagnostic proteins associated with incident ILD and develop a long-term prediction model.MethodsWe analyzed 52,7…

Magnetic enrichment–coupled flow cytometry for highly sensitive detection of persistent CAR-T cells in spiked and clinical peripheral blood samples

BackgroundLong-term monitoring of chimeric antigen receptor T-cell (CAR-T) persistence is essential for assessing therapeutic efficacy, particularly when circulating CAR-T cell levels decline following infusion. Although quantitative real-time PCR (qPC…

Immunogenicity and structure of a stabilized HIV-1 clade C Env from a pediatric elite neutralizer in complex with an autologous bnAb

IntroductionThe envelope (Env) glycoproteins derived from circulating viruses in elite-neutralizers (ENs), who naturally develop potent broadly neutralizing antibody (bnAb) responses, serve as a potential template for HIV-1 vaccine design. Here, we inv…

Age-stratified analysis reveals heterogeneity in factors associated with gastrointestinal bleeding in IgA vasculitis: a retrospective study in a large volume center

BackgroundGastrointestinal (GI) bleeding represents a severe complication of IgA vasculitis (IgAV). Most current analyses of risk factors aggregate patients across all ages, potentially obscuring critical age-specific differences. This study aimed to d…
