Pomegranate fruit presents strong anti-inflammatory, antioxidant, antiobesity, and antitumoral properties, thus leading to an increased popularity as a functional food nutraceutical source since ancient times. It can be divided into three parts: seeds, peel, juice, all of which seem have medicinal benefits. Several studies investigate its bioactive components means associate them with specific beneficial effect develop future products therapeutic applications. Many effects are related the...

AbstractObjective: Peroxisome proliferator-activated receptor γ (PPAR γ) is the molecular target for thiazolidinediones (TZDs), a class of synthetic antidiabetic agents. However, naturally occurring agonists PPARs remain largely unknown. Punicic acid (PUA) conjugated linolenic isomer found in pomegrante. The objective this study was to test hypothesis that PUA activates PPAR and thereby ameliorates glucose homeostasis obesity-related inflammation.Methods: ability modulate reporter activity...

Peroxisome proliferator-activated receptor (PPAR) gamma activation has been implicated in the prevention of immunoinflammatory disorders; however, mechanisms regulation effector and regulatory CD4+ T cell functions by endogenously activated PPAR-gamma remain unclear. We have used PPAR-gamma-deficient cells obtained from tissue-specific null mice (i.e., fl/fl; MMTV-Cre+) to investigate role endogenous on (Treg) function. Overall, we show that loss results enhanced Ag-specific proliferation...

Background Inflammatory bowel disease (IBD) therapies are modestly successful and associated with significant side effects. Thus, the investigation of novel approaches to prevent colitis is important. Probiotic bacteria can produce immunoregulatory metabolites in vitro such as conjugated linoleic acid (CLA), a polyunsaturated fatty potent anti-inflammatory This study aimed investigate cellular molecular mechanisms underlying efficacy probiotic using mouse model colitis. Methodology/Principal...

Inflammatory bowel disease (IBD) increases the risk of colorectal cancer. Probiotic bacteria produce immunoregulatory metabolites in vitro such as conjugated linoleic acid (CLA), a polyunsaturated fatty with potent anti-carcinogenic effects. This study aimed to investigate cellular and molecular mechanisms underlying efficacy probiotic mouse models cancer.The immune modulatory VSL#3 CLA were investigated inflammation-driven Colonic specimens collected for histopathology, gene expression flow...

Background and Purpose— The timely diagnosis of stroke at the initial examination is extremely important given disease morbidity narrow time window for intervention. goal this study was to develop a supervised learning method recognize acute cerebral ischemia (ACI) differentiate that from mimics in an emergency setting. Methods— Consecutive patients presenting department with stroke-like symptoms, within 4.5 hours symptoms onset, 2 tertiary care centers were randomized inclusion model. We...

Abscisic acid (ABA) has shown efficacy in the treatment of diabetes and inflammation; however, its molecular targets mechanisms action underlying immunomodulatory effects remain unclear. This study investigates role peroxisome proliferator-activated receptor γ (PPAR γ) lanthionine synthetase C-like 2 (LANCL2) as for ABA. We demonstrate that ABA increases PPAR reporter activity RAW 264.7 macrophages ppar expression vivo, although it does not bind to ligand-binding domain γ. LANCL2 knockdown...

Differentiation of CD4+ T cells into effector or regulatory phenotypes is tightly controlled by the cytokine milieu, complex intracellular signaling networks and numerous transcriptional regulators. We combined experimental approaches computational modeling to investigate mechanisms controlling differentiation plasticity in gut mice. Our model encompasses major pathways involved cell helper 1 (Th1), Th2, Th17 induced (iTreg). efforts predicted a critical role for peroxisome...

Enteroaggregative Escherichia coli (EAEC) is increasingly recognized as a major cause of diarrheal disease globally. In the current study, we investigated impact zinc deficiency on host and pathogenesis EAEC. Several outcomes EAEC infection were including weight loss, shedding tissue burden, leukocyte recruitment, intestinal cytokine expression, virulence expression pathogen in vivo. Mice fed protein source defined deficient diet (dZD) had an 80% reduction serum 50% luminal contents bowel...

Abstract Background Peroxisome proliferator-activated receptor γ (PPAR γ) is a nuclear whose activation has been shown to modulate macrophage and T cell-mediated inflammation. The objective of this study was investigate the mechanisms by which deletion PPAR in cells modulates immune cell distribution colonic gene expression severity experimental IBD.
