| Abstract | Emerging evidence shows that microRNAs (miRNAs) play an important role in pathogen-host interactions. Circulating miRNAs have been repeatedly and stably detected in blood and hold promise to serve as molecular markers for diverse physiological and pathological conditions. To date, the relationship between circulating miRNAs and active pulmonary tuberculosis (TB) has not been reported. Using microarray-based expression profiling followed by real-time quantitative PCR validation, the levels of circulating miRNAs were compared between patients with active pulmonary tuberculosis and matched healthy controls. The receiver operating characteristic curve was used to evaluate the diagnostic effect of selected miRNA. Bioinformatic analysis was used to explore the potential roles of these circulating miRNAs in active pulmonary tuberculosis infection. Among 92 miRNAs significantly detected, 59 miRNAs were downregulated and 33 miRNAs were upregulated in the TB serum compared to their levels in the control serum. Interestingly, only two differentially expressed miRNAs were increased not only in the serum but also in the sputum of patients with active pulmonary tuberculosis compared to the levels for the healthy controls. Upregulated miR-29a could discriminate TB patients from healthy controls with reasonable sensitivity and specificity. A number of significantly enriched pathways regulated by these circulating miRNAs were predicted, and most of them were involved in acute-phase response, inflammatory response, and the regulation of the cytoskeleton. In all, for the first time our results revealed that a number of miRNAs were differentially expressed during active pulmonary tuberculosis infection, and circulating miR-29a has great potential to serve as a marker for the detection of active pulmonary tuberculosis infection. |

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.
