| Abstract | Recovery from leukemia induced by Friend virus complex (FV) requires strong CD4+ helper, CD8+ cytotoxic T-lymphocyte, and B-cell responses. The development of these immune responses is dependent on the major histocompatibility complex (MHC) (H-2) genotype of the mouse. In H-2b/b mice, which spontaneously recover from FV-induced erythroleukemia, neutralization of gamma interferon (IFN-γ) in vivo inhibited recovery, which indicated that IFN-γ was a necessary component of the immune response to FV. Furthermore, in H-2b/b mice, high numbers of IFN-γ-producing cells were detected after FV infection, whereas in H-2a/b mice, which have a low-recovery phenotype, only low numbers of IFN-γ-producing cells were detected. Similarly, H-2bm14/b mice, which cannot recover from FV infection due to a point mutation in one allele of the H-2Db gene, also had low numbers of IFN-γ-producing T cells. Surprisingly, this effect was observed for both CD8+ and CD4+ T cells. These findings reveal a novel influence of MHC class I genes on CD4+ T-cell responses to viral infection. Furthermore, the influence of MHC class I genotype on the generation of both IFN-γ-producing CD4+ and CD8+ T cells helps explain the major impact of the H-2D gene on recovery from FV disease. |

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.
