Abstract:
Background: HIV (human immunodeficiency virus) is the virus that causes AIDS. This virus is passed from one person to another through blood-to-blood and sexual contact. In addition, infected pregnant women can pass HIV to their baby during pregnancy or delivery, as well as through breast-feeding. Objectives:To study the CCR5- 32 and SDF 1-3 A allelic frequence in the HIV -1 infected mothers and their children. Subjects and method: Amplificated on CCR5 and SDF1 gene by PCR and restriction of this fragment length polymorphisme (RLFP) assay for detection of the mutated gene by EcoR1 and Hpall. Results: No mutation of CCR5 was found but only mutation identified at the SDF1 gene. Mutation identified at the SDF1 gene of the mother was: homozygote 2.7% (accounted for 2/37 cases), heterozygote 40.54% (accounted for 15/37 cases) and at the children: homozygote 5.4% (accounted for 1/37 cases), heterozygote 45.95% (accounted for 17/37 cases). The CCR5 chemokin receptor is a co-receptor for M trofic HIV-1 strains, which predominate in the early stage of the HIV disease and SDF-1 natural ligand for the CXCR4 reception. The mutation of these genes protect from HIV-1 infection (slow progression).\r\n', u'Conclusion: It\u2019s necessary to find the mutation of CCR5 and CCR2b related the progression of HIV patients. \r\n', u'
