Photodynamic therapy in focal epithelial hyperplasia

Photodiagnosis and Photodynamic Therapy, 2023
Focal epithelial hyperplasia (FEH) is an uncommon benign disorder affecting the oral mucosa. It is primarily associated with human papillomavirus (HPV) infection and presents as multiple white or pink soft papules or nodules. Typically, FEH is asymptomatic.

Somatostatin receptor 4 (SSTR4) is a tumor suppressor in cutaneous and head & neck squamous cell carcinomas

Molecular Oncology, EarlyView.
This study identifies somatostatin receptor 4 (Sstr4) as a critical tumor suppressor against skin and head/neck cancers (HNSCC, cSCC, and BCC). The loss of Sstr4 removes a check on cell growth, causing hyperactivation of the MAPK‐ERK signaling pathway (↑).

IL‐7R‐Enriched Extracellular Vesicles From the Thymus Drive Colitis via Promoting Neutrophil Extracellular Trap Formation

Advanced Science, EarlyView.
Inflammatory bowel disease (IBD) pathogenesis remains unclear. This study reveals that thymus‐originated IL‐7R‐enriched extracellular vesicles exacerbate colitis by promoting neutrophil extracellular traps via a thymus‐gut axis, uncovering an inter‐organ communication mechanism in inflammatory bowel disease pathogenesis.

Single‐Cell Dissection of Therapy‐Induced Remodeling Uncovers a Fibroblast‐Driven Immunosuppressive Niche and Targetable Vulnerabilities in Lethal Prostate Cancer

Advanced Science, EarlyView.
Single‐cell longitudinal profiling reveals that androgen‐deprivation therapy induces a DPT+ fibroblast‐complement axis that suppresses macrophage inflammation and drives CD8+ T cell exhaustion in prostate cancer. Concurrently, resistant epithelial subpopulations persist and engage TSPAN1‐ and NRXN1‐mediated programs promoting CRPC and neuroendocrine ...
