| Abstract | The reported ability of SCID mice to accept xenografts of both human tumors and peripheral blood lymphocytes (PBL) provides the potential for the development of novel immunotherapy models in these animals. This study describes the development of a novel small animal model of human ovarian cancer. This was achieved by engrafting a human ovarian cancer cell line (Ovan-4) into the peritoneal cavity of immunodeficient SCID and immune reconstituted human PBL-SCID mice. When transplanted to SCID mice this cell line exhibited growth characteristics similar to the clinical disease observed in patients with implantation of metastatic nodules onto the interior surface of the peritoneal wall. Reconstituted human PBL-SCID mice challenged with identical numbers of Ovan-4 cells exhibited a significant increase in survival time, suggesting a role for cells of the human immune system in preventing the development of this type of malignancy in vivo. Furthermore, vaccination of human PBL-SCID mice against Ovan-4 produced tumour-specific human antibodies in the serum of these animals. Animals reconstituted with CD8-depleted PBL exhibited increased serum immunoglobulin levels and produced enhanced anti-Ovan-4 activity after vaccination. Subsequent challenge of these animals with Ovan-4 revealed a further increase in survival time. These results suggest that human antibodies may have a role in immunity against ovarian cancer and could be of therapeutic value in this type of 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.
