- immunogenic Previous Technique The little success achieved so far in the prevention and treatment of a group of infectious diseases, cancer and autoimmune diseases with vaccines is due to combinations of various factors, mainly the low immunogenicity of relevant antigens, the lack of knowledge on how to manipulate the regulation of Immune system and strategies to evade pathogens and tumors, including host immunosuppression.
- Those peptides, polypeptides and proteins (or their corresponding DNA sequences) present in tumors and normal tissues, or associated with pathogens that produce chronic infections by evading the action of the immune system are known within the state of the art as low immunogenic antigens. .
- growth factor receptors with kinase activity in tyrosine residues have been shown to be closely related to the development of tumors and tumor metastases, and their value has been proven in some cases as indicators of poor prognosis in cancer.
- receptors such as the epidermal growth factor receptor (EGF-R) or HER-1, the epidermal growth factor 2 receptor (HER-2), and the derived growth factor receptor of platelets (PDGF-R).
- EGF-R epidermal growth factor receptor
- HER-1 epidermal growth factor receptor
- HER-2 epidermal growth factor 2 receptor
- PDGF-R derived growth factor receptor of platelets
- IAE specific active immunotherapy
- Acquired immunity cells cannot distinguish structures that require an immune response from those that do not and therefore need to be instructed by innate immune system cells.
- An essential link between innate and acquired immunity is provided by the Antigen Presenting Cells (CPA), among which the Dendritic Cells (DC) are the most efficient inducers of both primary and secondary immune responses.
- CPA Antigen Presenting Cells
- DCs are crucial because they are the only CPAs capable of activating virgin T lymphocytes.
- molecules related to innate immunity have been identified that could be considered as a new generation of vehicles and adjuvants, because they have the ability to mature DCs and mediate the cross-presentation of antigens coupled to them.
- HSP thermal stress proteins
- HSP HSP
- researchers have the disadvantage that they must be obtained from the source of origin, for example, from tumors. This makes the procedure laborious and expensive and you never really know who is the antigen that has been responsible for the effect.
