Polydopamine Nanodots Ameliorate Inflammatory Bowel Disease by Restoring Redox Homeostasis and Intestinal Microenvironment

Advanced Science, EarlyView.
A novel melanin‐based therapeutic composed of ultrasmall polydopamine nanodots is employed as an efficient oral formulation for the targeted treatment of inflammatory bowel disease. The potential therapeutic mechanism of polydopamine nanodots mainly involves the elimination of excessive oxidative stress, the reduction of ROS‐mediated proinflammatory ...

Administration of Akkermansia muciniphila Ameliorates Dextran Sulfate Sodium-Induced Ulcerative Colitis in Mice

Frontiers in Microbiology, 2019
Inflammatory bowel diseases (IBDs) develop as a result of complex interactions among genes, innate immunity and environmental factors, which are related to the gut microbiota.

Intrinsic MicroRNA‐10a Restricts Regulatory T Cell Suppressive Function and Intestinal Repair by Coordinating Transcriptional, Metabolic, and Epithelial Repair Pathways

Advanced Science, EarlyView.
This study identifies microRNA‐10a (miR‐10a) as a key brake on regulatory T cell (Treg) suppressive function and intestinal repair. By targeting Blimp‐1, Uqcrq, and amphiregulin, miR‐10a restrains transcriptional, metabolic, and epithelial programs essential for Treg activity.

Ulcerative colitis disease activity as subjectively assessed by patient-completed questionnaires following orthotopic liver transplantation for sclerosing cholangitis [PDF]

, 1991
To assess whether or not liver transplantation and subsequent immunosuppression with cyclosporine and prednisone affect ulcerative colitis symptomatology, we surveyed by questionnaire all 23 surviving patients with pretransplant colonoscopy-documented ...

ETV1 Drives CD4+ T Cell‐Mediated Intestinal Inflammation in Inflammatory Bowel Disease Through Amino Acid Transporter Slc7a5

Advanced Science, EarlyView.
This study identifies the transcription factor ETV1 as a key driver of CD4⁺ T cell‐mediated intestinal inflammation in inflammatory bowel disease (IBD). ETV1 promotes CD4⁺ T cell activation, proliferation, and Th17 differentiation by activating the amino acid transporter SLC7A5, fueling metabolic reprogramming.

ULCERATIVE COLITIS IN CHILDREN [PDF]

Romanian Journal of Pediatrics, 2009
Chronic nonspecific ulcerative colitis remaine a disease of unkown etiology, although much new information continues to be gleaned from basic research and clinical trials. In most instances, ulcerative colitis respond to medical therapy.

Parabiosis, Assembloids, Organoids (PAO)

Advanced Science, EarlyView.
This review evaluates parabiosis, organoids, and assembloids as complementary disease models spanning systemic, organ, and multi‐organ levels. It highlights their construction strategies, applications, and current limitations, while emphasizing their integration with frontier technologies such as artificial intelligence, organ‐on‐a‐chip, CRISPR, and ...

Influence of Crohn’s disease related polymorphisms in innate immune function on ileal microbiome [PDF]

, 2019
We have previously identified NOD2 genotype and inflammatory bowel diseases (IBD) phenotype, as associated with shifts in the ileal microbiome (“dysbiosis”) in a patient cohort.

Genetically‐Programmed Hypervesiculation of Lactiplantibacillus Plantarum Increases Production of Bacterial Extracellular Vesicles with Therapeutic Efficacy in a Preclinical Inflammatory Bowel Disease Model

Advanced Science, EarlyView.
The development of a novel engineered strain of Lactiplantibacillus plantarum (Lp) is reported that can produce bacterial extracellular vesicles (BEVs) at >60‐fold higher yields than the unmodified parental strain. These Lp BEVs retain therapeutic bioactivity as validated in a mouse model of dextran sodium sulfate‐induced colitis.

The role of the Notch signalling pathway in the pathogenesis of ulcerative colitis: from the perspective of intestinal mucosal barrier

Frontiers in Medicine
Ulcerative colitis is a common digestive disorder worldwide, with increasing incidence in recent years. It is an urgent problem to be solved, as it seriously affects and threatens the health and life of the global population.
