Cysteine-cysteine chemokine receptor 5 (CCR5) profile of HIV-infected subjects attending University of Calabar Teaching Hospital, Calabar, Southern Nigeria
Abstract Background Cysteine-cysteine chemokine receptor 5 is the main HIV co-receptor involved in the virus and cell-to-cell spread. A variant of the CCR5 gene known as CCR5-Δ32 which is a product of 32 base pair deletion in the gene plays critical role in the infection and progression to AIDS. The...

| description | Abstract Background Cysteine-cysteine chemokine receptor 5 is the main HIV co-receptor involved in the virus and cell-to-cell spread. A variant of the CCR5 gene known as CCR5-Δ32 which is a product of 32 base pair deletion in the gene plays critical role in the infection and progression to AIDS. The study was carried out to determine the CCR5 genotype of HIV-infected subjects attending University of Calabar Teaching Hospital, Calabar. Methods A total of 100 subjects attending HIV clinic, University of Calabar Teaching Hospital were purposively recruited for this study. DNA was extracted from each sample using the Quick gDNA miniprep DNA extraction kit, Zymo Research. Polymerase chain reaction (PCR) was used in the amplification of CCR5 gene in each DNA in a 9700 ABI Thermo cycler and then resolved on 4% agarose gel electrophoresis. Result Out of the 100 samples assessed, 100 (100%) were homozygous for the CCR5 wild type gene (CCR5-wt), while none (0%) was homozygous for the CCR5-Δ32 (mutant type), and heterozygosity was not observed. Conclusion This study observed absence of CCR5-Δ32 deletion gene among the studied subjects in Calabar, implying lack of genetic advantage in HIV infection and possible rapid progression towards AIDS if other precautions are not checked. |
