Integrative transcriptomic and computational analysis associates Ms4a6c+ macrophages with fibrosis in radiation proctitis and computationally nominates MOTS-c as a candidate modulator

BackgroundChronic radiation proctitis (CRP) represents a significant clinical challenge characterized by irreversible fibrosis and a lack of specific pharmacological interventions. This study aimed to elucidate the cellular mechanisms underlying impair…

Adjuvant donafenib plus sintilimab therapy for hepatocellular carcinoma at high risk of recurrence after resection: a retrospective cohort study

BackgroundHepatocellular carcinoma (HCC) carries a high recurrence risk after curative resection, yet effective adjuvant strategies remain lacking. Although donafenib plus anti-PD-1 monoclonal antibodies has shown efficacy in advanced HCC, the effectiv…

An ARG1-associated immunometabolic program in bone marrow PMN-MDSC-like cells in multiple sclerosis and experimental autoimmune encephalomyelitis

BackgroundMultiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system. Recent work indicates that bone-marrow hematopoietic niches sense CNS autoimmunity and enhance myeloid output. However, whether MS bone mar…

Host cell protein impurities modify the immunomodulatory profile of pregnancy-specific glycoprotein 9, a cautionary tale

IntroductionPregnancy-specific glycoprotein 9 (PSG9) is one of 10 members of a conserved glycoprotein family within the carcinoembryonic antigen superfamily expressed by placental trophoblasts and secreted into maternal circulation. PSG1 and PSG9 induc…

Plasma metabolomic profiling identifies candidate biomarkers associated with sepsis diagnosis and mortality prediction

IntroductionSepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection; its early diagnosis and mortality prediction remain challenging, and conventional markers (CRP, PCT) have limited sensitivity and specificit…

A single dose of Dengvaxia is associated with transient reduction in dengue infection risk among dengue-naïve children

Dengvaxia® induces antibody responses in dengue virus (DENV)-naïve children, but the durability of these responses and their impact on subsequent wild-type (WT) DENV infection remain unclear. Although previous studies have primarily evaluated vaccine e…

Preliminary analysis of the proportions and characteristics of dual TCR T cells and dual BCR B cells in echinococcus granulosus-infected mice using scRNA+TCR+BCR-seq

IntroductionCystic echinococcosis (CE) is a zoonotic parasitic disease caused by Echinococcus granulosus, and the T and B cell responses and regulatory mechanisms in CE remain unclear.MethodsIn this study, we analyzed the data of peripheral blood and s…

Non-PML neuroinvasive infections reported with multiple sclerosis disease-modifying therapies: a mechanism-based pharmacovigilance study, 2004–2025

BackgroundMultiple sclerosis (MS) disease-modifying therapies (DMTs) alter host immunity and may produce pathogen-specific susceptibility to neuroinvasive infection. Comparative evidence is limited because events are rare and postmarketing research foc…
