In the present communication, the repertoire of alloreactive cytotoxic T lymphocytes (CTL) clones was quantitatively investigated by limiting dilution analysis and by target inhibition with a panel of monoclonal antibodies (mAb). These mAb have previously been shown to define two distinct alloantigenic domains, A and B, on the H-2Kk molecule. The Poisson distribution analysis of H-2Kk-specific ...
Cytotoxic T-lymphocytes (CTL) are famous for their ability to kill tumor, allogeneic and virus-infected cells. However, an emerging literature has now demonstrated that CTL also possess the ability to directly recognize and kill bacteria, parasites, and fungi. Here, we review past and recent findings demonstrating the direct microbicidal activity of both CD4(+) and CD8(+) CTL against various mi...
Cancer stem cells (CSCs)/cancer-initiating cells (CICs) are characterized as a small population of cancer cells that have high tumor-initiating ability. CSCs/CICs are resistant to several cancer therapies, and eradication of CSCs/CICs is essential to cure cancer. How can we eradicate CSCs/CICs? Cytotoxic T lymphocytes (CTLs) might be a promising answer.
Human T-cell lymphotropic virus type 1 (HTLV-1) is associated with adult T-cell leukemia/lymphoma (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Only a limited percentage of infected individuals develop disease in response to the virus while the majority remain asymptomatic and HAM/TSP is the most common clinical manifestation of the virus. HAM/TSP is an inflamma...
A sensitive procedure employing limiting dilution of activated lymphocytes and 51Cr release from highly labeled target cells was used to derive minimal estimates of the absolute frequency of cytotoxic T lymphocytes (CTL) present in a population of mouse lymphocytes activated to alloantigens of the major histocompatibility complex in bulk mixed lymphocyte cultures. From this figure (0.7-1.2%), t...
