Abstract
Some literature reviews have been carried out about the role of perforin in medicine. The first step involved a systematic search to identify relevant studies published between 2001 and 2019 in the following electronic databases - EBSCO host, Scopus, Science Direct, Web of Science, and Elsevier. By analyzing the available literature, it can be concluded that perforin plays an important role in cytoxical activity of natural killer cells (NK) and CD8+ T cell. NK and CD8+use the same mechanism for destroying target cells. This article cites the disease hemophagocytic lymphohistiocytosis (HLH) which is characterized by heavy abnormalities in the immune system. The point is that this disease is caused by perforin gene mutation. The key is the application of properly sensitized dendritic cells (DCs) because they are effective in immunotherapy against cancer. It may be effective in γ-irradiated colon cancer cell lines HT-29. Growth hormone inhibiting hormone (GIH) induces maturation and activation of DCs. In that way, GIH-Dcs shows increased cytotoxic activity and higher perforin and granzyme expression. So, this means that theoretical research has shown that efficient activity against cancer is induced when DCs are sensitized with γ-irradiated cancer cells. In that way, through a direct increase of cytotoxicity and indirect T cell activation,there can beanti-tumor activity. It is suggested to continue scientific research about the role of perforin in the future.
