MicroRNA155 Expression in Different Phenotypes and Genotypes of Behçet’s Disease in a Sample of Egyptian Patients

AIM: To display microRNA155 (miRNA155) expression in different entities of Behçet’s disease (BD), and to find out if expression is affected in more than one of disease status than another, either phenotypically, according to HLA B51 expression, presence of family history, or patients’ age. METHODS: Thirty BD patients (13 of which were HLAB51 positive) and 15 healthy subjects’ samples were obtained. White blood cell miRNA155 expression in both types of samples was estimated. RESULTS: Results showed that there is a degree of relation between decrease of miRNA155 expression and different disease aspects, and also, that miRNA155 has an inverse relation with the patients’ ages. CONCLUSION: MiRNA155 might be used as a measure of disease of different phenotypes, and that any manifestation of the disease can happen when the expression level decreases.
