| Abstract | The cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and costimulatory molecule (CD80/CD86) genes are important susceptibility genes associated with autoimmune diseases. CTLA-4 polymorphisms have been found to be associated with various autoimmune diseases. However, the association data are inconsistent for rheumatoid arthritis (RA). We investigated the genetic association of CTLA-4 and CD86 polymorphisms with RA in a Chinese population. Four single nucleotide polymorphisms (SNPs) (rs5742909 and rs231775 in CTLA-4, and rs17281995 and rs1129055 in CD86) were genotyped in 213 patients with RA and 303 healthy controls using polymerase chain reaction-restriction fragment length polymorphism. The genotype and allele distributions of rs5742909 differ significantly between RA patients and controls (P < 0.05) and the dominant model was found to be the best inheritance model. Stratification studies showed that CTLA-4 gene polymorphisms were more significantly associated with rheumatoid factor-negative and anti-cyclic citrullinated peptide-negative subgroups in the southeastern Han Chinese population. We also found that the haplotype of 2 CTLA-4 SNPs showed significant association with the disease (P = 0.0025) with the T-A (OR = 1.88, 95%CI = 1.12-3.15) and T-G (OR = 3.45, 95%CI = 1.10-10.87) haplotypes being observed more frequently in cases than in controls. We failed to find any significant association of the 2 CD86 SNPs with RA. These results indicate that the polymorphisms of CTLA-4 (rs5742909) may be important genetic factors for RA risk in the southeastern Han Chinese population. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
