| Abstract | Immunosuppressive mediators in tuberculosis pleurisy (pleural fluid (PF)) are associated with the course of disease, but they remain poorly defined. To study the local immune status of patients with tuberculosis pleurisy, we examined the effect of PF on the functions of T cells and the differentiation of Th1 cells. PF could inhibit the ability of T cells to produce cytokines. However, tumor-necrosis factor (TNF)-α derived from non-T cells was not impaired. Further analysis indicated that cell activation and cell cycle progression were also suppressed. Moreover, PF could inhibit Th1 cell differentiation. Importantly, we found that inhibitors of indoleamine 2,3-dioxygenase (IDO) and adenosine and neutralizing antibodies against IL-10 and transforming growth factor (TGF)-β could reverse cytokine production, suggesting that IDO, adenosine, IL-10 and Transforming growth factor–β1 in PF might take part in impairing T-cell functions. Taken together, our data demonstrate for the first time that several immunopathological factors participate in the downregulation of T-cell functions in local PF. |

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.
