SHR rats, 1 week of age, were i.p. inoculated with allogeneic JB LAK cells generated by 3-day incubation of spleen cells of JB rats in CM-IL 2. The spleens were removed 4 and 12 weeks later and their cells were tested for proliferative potential to mitogens and their response and production of IL2. The results demonstrated that the allo-LAK recipients showed no signs of acute or chronic GvH disease but showed immune response equivalent to or higher than the normal controls. Severe functional defects were observed in the newborn SHR rats after i.p. inoculation of allogeneic fresh spleen cells from JB rats. The results strongly suggest that allogeneic LAK cells be ineffective in terms of induction of GvH disease or GvH associated immunodeficiencies (GvHID). Therefore, this might be promising in clinical trials on cancer adoptive immunotherapy with allogeneic, instead of autologous, LAK cells.

Bone Marrow Sampling and Transplants01:22

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...
Special Features of Adaptive Immunity01:20

Special Features of Adaptive Immunity

The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
Tissue Transplantation01:24

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
