Peripheral immune phenotyping identifies an immunosuppressed sepsis endotype with potential relevance for immune stratification

BackgroundSepsis is characterized by profound immune dysregulation, yet the biological significance and clinical application of peripheral immune phenotyping in sepsis remain incompletely defined. This study aimed to define internally identified immune…

Vunakizumab-induced severe ulcerative colitis during treatment of psoriatic arthritis: a case report and literature review

BackgroundInterleukin-17A (IL-17A) inhibitors are effective therapies for psoriasis (PsO) and psoriatic arthritis (PsA), yet they may induce or exacerbate inflammatory bowel disease (IBD). Vunakizumab is a novel humanized anti-IL-17A monoclonal antibod…

Chronic low-grade inflammation drives skeletal aging and neurocognitive decline: inflammaging as a central hub coupling bone–brain aging

BackgroundGlobal population aging has driven a marked rise in the co-prevalence of osteoporosis and cognitive impairment, and a bidirectional epidemiological association between the two conditions is now supported by multiple meta-analyses. The shared …

Mammalian cell-derived extracellular vesicles remodel the immune-repair microenvironment in osteoarthritis: from pathological signal transmission to regenerative therapy

Osteoarthritis is a whole-joint disease involving articular cartilage, synovium, subchondral bone, fat pad, meniscus, blood vessels, and sensory nerves. Its core pathology is not simply passive wear of the cartilage matrix, but rather reciprocal drivin…

Analytical validation of a multiplexed peptide microarray for multi-antigen Epstein–Barr virus serological profiling across diverse clinical specimens

BackgroundEpstein–Barr virus (EBV) infects more than 95% of adults and is associated with outcomes ranging from asymptomatic latency to infectious mononucleosis (IM), malignancies, and multiple sclerosis (MS). Conventional ELISA-based EBV serology is o…

The role of lysine acylation in metabolic dysregulation and inflammatory responses within the hepatic immune microenvironment of MASLD

Metabolic dysfunction–associated steatotic liver disease (MASLD) is a chronic liver disorder characterized by metabolic abnormalities, persistent low-grade inflammation, and alterations in hepatic immune function. In addition to lipid accumulation and …
