Peptide-Based Vaccine Development for Pancreatic Cancer
In recent years, peptide-based therapeutic tumor vaccines have received much attention as one of the effective means of tumor immunotherapy. At present, a variety of peptide-based therapeutic cancer vaccines have been developed with remarkable success. Likewise, combinations of peptide-based vaccines and other therapies have shown superior efficacy in enhancing anti-cancer activity. Alfa Cytology has advanced vaccine development platforms and extensive experience in pancreatic cancer (PC) research. We are offering peptide-based vaccine development services for PC, including peptide-based vaccine preparation, pre-clinical studies, and neoantigen-based peptide vaccine development.
Peptide-based Cancer Vaccines
Peptide-based cancer vaccines typically consist of 20-30 amino acids containing specific epitopes of highly immunogenic antigens, triggering the desired immune response. These vaccines utilize two types of peptides: short peptides (8-12 amino acids) and synthetic long peptides (20 amino acids or more). Short peptides, despite their short half-lives and susceptibility to degradation in serum, can bind to the HLA class I groove on the surface of nucleated cells without processing by professional antigen-presenting cells (APCs). To enhance their effectiveness, short peptides are usually bound to carrier proteins, allowing uptake and processing by APCs, thereby eliciting a potent immune response.

In contrast, synthetic long peptides are more stable and immunogenic. They are taken up and processed by APCs to produce peptides presented by both HLA class I and II molecules, generating strong and durable anti-tumor immune responses. This includes activation of CD8+ T cells, CD4+ T cells, and antibody production by B cells. Peptide vaccines offer several advantages over other types of vaccines, particularly in terms of safety and ease of production, making them a promising approach in cancer immunotherapy.
Advantages of Peptide-based Cancer Vaccine
