Stimulation of Ileal Epithelium Growth and Regeneration by Dietary Nucleotide Extracts

open access: yesActa Medica, 2004
The gastrointestinal tract epithelium plays an important role not only in digestion and absorption of nutrients, but also in antigen and pathogen signal translocation toward the gut associated lymphoid tissue.

Case Report of a Rapidly Progressive Indolent T‐Cell Lymphoma of the Gastrointestinal Tract

open access: yesDEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Indolent T‐cell lymphoma of the gastrointestinal tract (iTCL‐GI) is a relatively newly recognized disease entity. iTCL‐GI was first proposed by Perry et al. in 2013, before it was formally incorporated as a distinct disease category in the fifth edition of the World Health Organization Classification of Hematolymphoid Tumors: Lymphoid ...

Peyer's Patches in the Terminal Ileum in Ulcerative Colitis: Magnifying Endoscopic Findings. [PDF]

open access: yes, 2010
Peyer's patches (PPs), a major component of the gut-associated lymphoid tissue, serve as important antigen entry sites in mucosal immunity. PPs may play a role in the extension of ulcerative colitis (UC) into the terminal ileum.

Immunometabolic Modulation by Low‐Dose Sodium Butyrate: PI3K/Akt/mTOR Signalling Orchestrates Macrophage Polarization to Protect Against Clostridioides difficile Colitis

open access: yesImmunology, Volume 179, Issue 4, Page 594-608, December 2026.
Clostridioides difficile toxins TcdA and TcdB enter intestinal epithelial cells (IECs) via specific receptors, disrupt tight‐junction integrity and activate PI3K/Akt/mTOR signalling, promoting inflammasome assembly and IL‐1β release. Toxin‐induced IEC apoptosis further weakens the epithelial barrier.

m6A‐Driven Pexophagy Triggers Placental Ferroptosis to Impair Fetal Growth Upon Environmental Stress

open access: yesAdvanced Science, Volume 13, Issue 61, 3 November 2026.
Prenatal environmental stress exposure promotes m6A modification to drive PEX2‐dependent pexophagy, thereby causing placental ferroptosis and FGR. ABSTRACT The role and underlying mechanisms of placental ferroptosis in fetal growth restriction (FGR) induced by environmental stress remain poorly understood.
