TL;DR

It is reported that phosphodiesterase 4D (PDE4D) is markedly up-regulated in glandular epithelial cells from both pSS patients and murine models, correlating tightly with diminished saliva output and heightened B cell infiltration.

T Cell-Derived IFN-γ Activates Ferroptosis in Lacrimal Luminal Ductal Cells via JAK-STAT Signaling in Sjögren's Disease-Related Dry Eye.

Purpose Sjögren's disease (SjD) leads to severe dry eye disease (DED) via lacrimal gland inflammation and dysfunction, yet the specific pathogenic mechanisms remain unclear. In this study, we aimed to deeply identify the vulnerable lacrimal epithelial subclusters and elucidate the immune-epithelial cross-talk. Method...

The FOXA2/ST3GAL4 axis regulates airway mucus hypersecretion by modulating the ERK/NF-κB pathway.

Airway mucus hypersecretion is a pathophysiological process characterized by excessive mucus production driven by diverse pathogenic factors, which exacerbates clinical outcomes in susceptible populations by increasing morbidity and mortality. MUC5AC, the predominant mucin secreted by airway goblet cells, serves as one...

JUND-DNAJB1-p21 axis drives fibroblast senescence to recruit CD4⁺ T cells in salivary gland pathogenesis of Sjögren’s disease

Advanced age is a recognized risk factor for primary Sjögren’s disease (pSjD), suggesting a role for aging-related mechanisms in its pathogenesis. However, whether cellular senescence directly drives autoimmune inflammation and glandular dysfunction remains unclear. Furthermore, the specific role of senescent fib...

Introduction: Corticotroph pituitary tumours (ACTHomas) are the leading cause of Cushing's disease and remain clinically challenging due to their heterogeneous behavior and the limited medical options for refractory or aggressive cases. Growing evidence suggests that endocrine tumour phenotypes are strongly influence...

The Epstein-Barr virus-induced gene 2—Cholesterol 25-hydroxylase axis is essential for the recruitment of mast cell progenitors 2260869

Basophils, eosinophils, and mast cells (MCs) are granulocytes that expand in the airways during type 2 inflammation (T2I)-associated diseases, where they are thought to play a major role in disease pathobiology. While the chemotactic signals recruiting basophils and eosinophils to inflamed tissues are well charac...

Eosinophil—macrophage crosstalk controls obesity-associated adipose inflammation and is stabilized by RELMα in a sex-dependent manner 2309540

Eosinophils are immune cells with terminal effector functions in type 2 immune responses, yet recent findings suggest that they exhibit functional plasticity and heterogeneity dependent on tissue-specific cues. 10x Genomics Fixed RNA Profiling was performed on Siglec-F+ purified adipose eosinophils and mac...
