چکیده

Three groups of conventional therapies include salicylates, immunosuppressants and antibiotics. Yet relief is often shortlived and comes with significant side effects. 80% and 45% of CD and UC patients (Respectively) will still require surgery [16]. Biological response modifiers or ‘biologics’, macromolecules that target inflammatory lymphocytes or the cytokines they produce [7], have more recently emerged as another highly effective therapeutic class. In 1998, the FDA approved infliximab, with a high response rate, significant mucosal and fistula healing and long-term remissions in Crohn’s disease. Other biologics targeting p40, p19, IL-12, IL-17 and anti-alpha 4 integrin [7, 8] are either marketed or in various development stages. However as many as 30% of patients will not respond to biologics and half of those who initially respond, will relapse within a year. None have significant impact on surgical intervention rates [9].

Oral Delivery of Particulate Transforming Growth Factor Beta 1 and All-Trans Retinoic Acid Reduces Gut Inflammation in Murine Models of Inflammatory Bowel Disease.

BACKGROUND AND AIMS We investigated oral delivery of transforming growth factor beta 1 [TGFβ]- and all-trans retinoic acid [ATRA]-loaded microspheres as therapy for gut inflammation in murine models of inflammatory bowel disease [IBD]. METHODS ATRA and TGFβ were separately encapsulated in poly [lactic-co-glycolic] acid or polylactic acid microspheres [respectively]. TGFβ was encapsulated usin...

Retinoic acid inhibits Th17 polarization and enhances FoxP3 expression through a Stat-3/Stat-5 independent signaling pathway.

CD4(+) helper T (Th) cells play a crucial role in the delicate balance between host defense and autoimmune disease. Two important populations of helper T cells are the proinflammatory, interleukin-17 (IL-17)-producing (Th17) cells and the anti-inflammatory forkhead box P3-positive (FoxP3(+)) T regulatory (Treg) cells. Here we show that all-trans retinoic acid (ATRA) and other agonists of the re...

Activation of beta-catenin in dendritic cells regulates immunity versus tolerance in the intestine.

Dendritic cells (DCs) play a vital role in initiating robust immunity against pathogens as well as maintaining immunological tolerance to self antigens. However, the intracellular signaling networks that program DCs to become tolerogenic remain unknown. We report here that the Wnt-beta-catenin signaling in intestinal dendritic cells regulates the balance between inflammatory versus regulatory r...

Prophylactic effect of all-trans retinoic acid in an amyloid-beta rat model of Alzheimer\'s disease

Introduction: Retinoid signaling has been argued to have favorable effects on Alzheimer's disease (AD). We studied the role of chronic intracerebroventricular (ICV) injection of all-trans retinoic acid (ATRA) on the amyloid-beta (Aβ) model of AD. Methods: Adult male rats weighing 260-330 g were divided into 12 groups of 8 each. Six groups of rats received ATRA (3nM, 30nM, 3μM, 0.3mM, 30...
