Abstract:
In the present work, we established a rapid, cost-effective and high-throughput method for genotyping using a multiplexed microsphere-based suspension array platform - Luminex(®) ×MAP™, which enabled us to analyse two SNPs in the promoter of IL-6 gene, determining haplotypes associated with different levels of expression. Using this system, IL-6 diversity in four different ethnic groups - East Asians, Caucasians, Hispanic and African Americans - was assessed. Results showed a significant variability in terms of allele, genotype and haplotype distribution. Considering the important immunoregulatory role of this cytokine and as a clinically relevant marker, this genotyping approach will provide a powerful tool for disease association or transplant outcome studies.

Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
