| Abstract | In the present study, the frequency and function of B10 cells in patients with rheumatoid arthritis (RA) was examined. A total of 24 healthy controls and 97 patients with RA were enrolled in the present study. Among the 75 patients with an active disease status, 51 patients received either no treatment or were treated with nonsteroidal antiinflammatory drugs (NSAIDs) only, while 24 patients underwent a disease relapse. Flow cytometry was used to assess the frequency of CD19(+)CD24(hi)CD38(hi) interleukin (IL)10(+) cells stimulated by lipopolysaccharide plus CD40L for 48 h, followed by restimulation with phorbol myristate acetate and ionomycin for 5 h. The correlation of CD19(+)CD24(hi)CD38(hi)IL10(+)cell frequency with clinical/laboratory characteristics and with levels of inflammatory cytokines were assessed along with the effects of CD19(+)CD24(hi)CD38(hi) cells on the proliferation and tumor necrosis factor expression of CD3+ T cells. The median frequency of IL10competent cells among the CD19+ B cells was significantly increased among patients with RA with active disease. However, a subgroup of patients with a high disease status that received no treatment/NSAIDs exhibited a significantly lower frequency (≤1% IL10+ B cells). These patients exhibited longer symptom duration, a greater number of tender and swollen joints and a higher patient global visual analogue scale and disease activity score in 28 jointsC reactive protein. Functional assays further demonstrated that B10 cells from the subgroup with ≤1% IL10+ B cells secreted significantly lower levels of IL10 and exerted a significantly decreased suppressive effect on CD3+ T-cell proliferation and tumor necrosis factor production. The frequency and functional heterogeneity of B10 cells in patients with RA at different disease stage suggested that further investigation on the underlying mechanism of the generation and function of B10 cells in patients with RA is required prior to use in clinical practice. |

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.
