| Abstract | Toll-like receptors (TLRs) are pattern-recognition receptors that recognize microbial ligands and subsequently trigger intracellular signaling pathways involving transcription factors such as NFκB and MAPKs such as p38. TLR signaling can regulate both transcriptional and post-transcriptional events leading to altered gene expression and thus appropriate immune responses. The interleukin-1 receptor-associated kinase (IRAK) family comprises four kinases that regulate TLR signaling. However, the role of IRAK-2 has remained unclear, especially in human cells. Recent studies using cells from in-bred Irak2 −/− mice showed that murine IRAK-2 was not required for early TLR signaling events but had a role in delayed NFκB activation and in cytokine production. IRAK-2 in mice has four splice variants, two of which are inhibitory, whereas human IRAK-2 has no splice variants. Thus IRAK-2 in mice and humans may function differently, and therefore we analyzed the role of IRAK-2 in TLR responses in primary human cells. siRNA knockdown of IRAK-2 expression in human peripheral blood mononuclear cells showed a role for human IRAK-2 in both TLR4- and TLR8-mediated early NFκB and p38 MAPK activation and in induction of TNF mRNA. These data conflict with findings from the in-bred Irak2 −/− mice but concur with what has been seen in wild-derived mice for TLR2. Moreover, human IRAK-2 was required for regulating MyD88-dependent TNFα mRNA stability via the TNF 3′UTR. Collectively, these data demonstrate for the first time an essential role for IRAK-2 in primary human cells for both transcriptional and post-transcriptional TLR responses. |

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.
