Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

Advanced Science, Volume 13, Issue 19, 2 April 2026.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...

Decoding the Pathophysiology of Autoimmune Diseases—Mechanism, Triggers, and Nanotherapeutics: A Review

Advanced NanoBiomed Research, Volume 6, Issue 4, April 2026.
This review highlights how autoimmune diseases arise from intertwined immunological, genetic, and environmental factors, emphasizing gut microbiota dysbiosis as a pivotal driver. It outlines emerging nanotechnology‐based strategies—such as liposomes, hydrogels, and polymeric nanoparticles—that enhance targeted drug delivery, minimize systemic toxicity,

Role of Ca2+‐Dependent Epithelial‐Mesenchymal Transition in Malignant Progression of Colorectal Cancer: Special Focus on REG Iα/EDNRB

Cancer Medicine, Volume 15, Issue 4, April 2026.
In CRC, increased REG1α upregulates membrane‐bound EDNRB expression. Activated EDNRB, a GPCR, triggers IP3 production via PLCε, leading to ER‐mediated Ca2+ release into the cytosol. This elevated Ca2+ activates CaMKII, promoting cell proliferation and EMT while inhibiting apoptosis, thus fueling CRC malignant progression. ABSTRACT Background Colorectal

Perforated Gastric Ulcer due to a Giant Trichobezoar: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT The term “trichobezoar” refers to foreign and indigestible material in the gastrointestinal tract, and it can indicate several underlying mental illnesses. A 38‐year‐old woman reported experiencing sudden intensive abdominal pain, along with a two‐month history of vomiting, nausea, exhaustion, and abdominal discomfort.

Case Report: Scar‐Like Alterations of the Gastric Mucosa Observed Under Endoscopy in Collagenous Gastritis

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Collagenous gastritis (CG) is an uncommon disorder of the digestive system, characterized by marked thickening of the subepithelial collagen band and infiltration of inflammatory cells within the lamina propria. The etiology and pathogenesis of CG remain not fully understood, and its diagnosis is contingent upon histopathological evaluation ...
