ABSTRACT
INTRODUCTION:
Inflammatory bowel diseases (IBD) are immune-mediated disorders that result from an aberrant immunological response to the gut luminal antigen in genetically susceptible patients. IBD is categorized into two serotype, Crohn's diseases (CD) and ulcerative colitis (UC), both subtype are important cause of gastrointestinal diseases. The increasing rate of hospitalization, with the high economic burden experienced by the IBD patients, calls for more concerted research efforts to design a potent and affordable treatment option for the treatment of IBD. AIMS/OBJECTIVE:
This research was designed to test the efficacy and potency of ß-D Mannuronic acid (M2000) and assess if it could serve as a better therapeutic option in the treatment of IBD.METHODOLOGY:
Ten (10)ml of blood was aseptically collected into an EDTA container, from 24 IBD patients and 24 normal healthy controls. PBMC was isolated and stimulated with 1µg/ml of LPS in cell culture plate and incubated for 4h. The cells were later treated with 10µg/ml and 50µg/ml of ß-D Mannuronic acid (M2000) and incubated for 24h at 37°C under 5% CO2 and 100% humidity. The RNA extractions, cDNA synthesis, and QRT-PCR were performed.RESULTS:
Our findings showed a significant down-regulation of TNF-α and IL-17 gene expression, while the expression of FOXP3 gene was significantly up-regulated.CONCLUSION:
This result has indicated that ß-D Mannuronic acid (M2000) have immunoregulatory and anti-inflammatory effects on these cytokines that are pivotal in the pathogenesis of IBD.Palabras clave
