Abstract
Aim of study: After the treatment of tumors, we often encounter a minimal residual sickness. However, the elimination of these leftover tumor cells is crucial for the patient.
In the past years one of the most discussed options for this treatment is Imunotherapy, mainly by Dendritic cells. Dendritic cells are the most efficient cells out of the antigen presenting cell group.
Methods and results: In the first part of the project, we perfected a technique of inducting a tumor on an experimental model. We inducted the tumor by the use of Carcinogenic substances or with the help of the Sarkom line imortalized fibroblasts.
Another important part of the project was perfecting the method for the preparation of undeveloped dendritic cells from periphery blood monocytes. After these significant procedures were developed and perfected we moved onto the main part of the study.
The Induction of a tumor by the carcenogenic substances Ethylennitrosamin and Phenobarbital was successful only in 20 % of the cases and therefore, was unusable for our experiment. We inducted the tumors with the Sarkom line method.
After the application of dendritic cells into the tumor, a decrease in the development of the growth of the tumor was achieved. Conclusion: Imunotherapy using dendritic cells as a basis for treatment is a perspective method for treatment of tumors.
