As someone deeply interested in the structural biology of peptides, I have found that the peptide database bruggen—formally known as the Cancer Antigenic Peptide Database—stands as a cornerstone resource. Developed by Pierre van der Bruggen and his colleagues, this repository has provided a foundational framework for researchers mapping the landscape of T cell-defined human tumor antigens.
The Evolution of Antigenic Peptide Cataloging
When we discuss the Cancer Antigenic Peptide Database, we are looking at a legacy project that began in 2001. The primary intent behind this database was to compile the most relevant human tumor antigens into a structured, accessible format. Each entry in the database corresponds to a specific peptide, providing a detailed l by PE Bonté·2022·Cited by 75—Importantly, thepeptidesidentified in immunopeptidomicdatabasesare also biased for chromosome 7, further and independently validating our Read more ook at sequences that have been identified through rigorous scientific literature review.
In my experience navigating these digital archives, the utility of the peptide database lies in its strict inclusion criteria. Unlike broader, automated repositories, the work curated by researchers like Van der Bruggen focuses on high-confidence data, which is essential when one is researching the peptides involved in immune recognition.

When we look at databases like CancerPDF—which focuses on the peptidome of human biofluids—we see how the foundational principles of the original peptide database are being expanded to cover broader biological contexts.
Whether you are looking for a peptide associated with specific membrane proteins or exploring the role of neoantigens, the DB (database) landscape is vast. Other resources, such as TANTIGEN or dbPepNeo, have emerged to complement the original work, offering deeper insights into the 368 proteins where these antigenic sequences are often located.
Practical Utility for Researchers
For those of us interested in the molecular signatures of biology, the peptide database bruggen remains a vital reference point. Its historical significance is evidenced by its frequent citation in studies concerning:

* The identification of shared tumor-specific antigenic sequences.
* The analysis of post-translational modifications.

Conclusion
The peptide database ecosystem has grown significantly over the last two decades. While there are now many specialized platforms available, the work initiated by Pierre van der Bruggen provides the essential DNA for how we organize and understand these complex molecular strings today. By maintaining such a rigorous peptide repository, the scientific community ensures that foundational data remains accessible, allowing for a more nuanced understanding of the human peptidome. Whether you are searching for a specific database entry or conducting a broad investigation, recognizing the contributions of these early, manually curated resources is essential for high-quality research.
