Definitions
- the purpose at the biological level is to activate the immune system to trigger a response that attacks the tumor.
- This is based on the tumors they contain different (or mutated) proteins with respect to those present in normal tissue or overexpress certain genes, these are tumor associated antigens (AATs).
- AATs tumor associated antigens
- These can be processed and presented by antigen presenting cells, such as dendritic cells, which then produce the activation of cytotoxic T helper and T lymphocytes. Subsequently, activated T lymphocytes can produce direct or indirect responses to induce the death of tumor cells. Therefore, when using this technique to generate cell bodies from tumor cells that contain AATs and inject an oncogenic patient with such preparation, the injection contains AATs that can trigger an immune response that allows attacking the cells that make up the tumor of the patient.
- FIG. 1 Analysis of surface markers CD1 1 c, CD86, MHC class II and CCR7 in mouse dendritic cells (DCs) C57BL / 6 by flow cytometry.
- black line corresponds to the negative control (untreated DCs), while the red line corresponds to the treatment performed in each experiment:
- dendritic cell activation In addition to the previous evidence, in the laboratory we assess whether cell bodies are capable of producing dendritic cell activation (DCs), immune system cells that are capable of recognizing antigens (either from pathogens or in this case from cells tumor) and trigger subsequent activation of cytotoxic T helper and T lymphocytes, which have a great capacity to induce the death of tumor cells.
- DCs dendritic cell activation
