Ccl2/Mcp-I Genotype-Phenotype Relationship In Latent Tuberculosis Infection, Rabia Hussain, Ambreen Ansari, Najeeha Talat, Zahra Hasan, Ghaffar Dawood

Department of Pathology and Laboratory Medicine

Among the known biomarkers, chemokines, secreted by activated macrophages and T cells, attract groups of immune cells to the site of infection and may determine the clinical outcome. Association studies of CCL-2/MCP-1 -2518 A/G functional SNP linked to high and low phenotypes with tuberculosis disease susceptibility have shown conflicting results in tuberculosis. Some of these differences could be due the variability of latent infection and recent exposure in the control groups. We have therefore carried out a detailed analysis of CCL-2 genotype SNP -2518 (A/G transition) with plasma CCL-2 levels and related these levels to tuberculin skin test positivity in …
