Nutzung des menschlichen Peptidoms zur Entwicklung neuer antimikrobieller und anti-Krebs Therapeutika

Ziel des SFB1279 ist es, körpereigene menschliche Peptide zu entdecken, die eine Schlüsselrolle bei der Kontrolle von humanen Pathogenen und Krebserkrankungen spielen, und diese für mögliche therapeutische Anwendungen zu optimieren. Um dies zu erreichen, nutzt der SFB das Peptidom, also die Gesamtheit der Peptide im menschlichen Körper. Diese Quelle ist von enormem Interesse, da Peptide zahlreiche physiologische und pathologische Prozesse steuern. Darüber hinaus sind Peptide Schlüsselregulatoren und Effektoren der angeborenen und adaptiven Immunität und modulieren das Überleben, das Wachstum und die metastatische Ausbreitung von Krebszellen. Trotz seiner Bedeutung ist das menschliche Peptidom funktionell kaum erforscht. Der Hauptgrund dafür ist seine enorme Komplexität, die die Aufreinigung einzelner bioaktiver Substanzen schwierig macht. In unserem SFB verwenden wir Peptidbanken aus menschlichen Körperflüssigkeiten und -geweben zur schrittweisen Isolierung spezifischer bioaktiver Peptide aus Gemischen von bis zu Millionen natürlich vorkommender Verbindungen. Der Ansatz hat sich als sehr erfolgreich erwiesen und die Entdeckung zahlreicher körpereigener Peptide ermöglicht, die eine antimikrobielle und/oder antineoplastische Aktivität aufweisen. Die im SFB verfügbare Expertise ermöglicht es, die Wirkweise und physiologische Relevanz natürlicher Peptide aufzuklären und sie für therapeutische Entwicklungen zu optimieren. Der Forschungsverbund ist interdisziplinär und umfasst drei kooperative Forschungsbereiche, die von zwei Technologieplattformen unterstützt werden. Die erste Plattform stellt den Forschungsprojekten Peptidbibliotheken zur Verfügung und unterstützt sie bei der Peptidaufreinigung, Synthesen, Strukturanalysen und Modellierungen. In Forschungsbereich A werden neue antimikrobielle Peptide charakterisiert und optimiert. Projekte in Bereich B analysieren die Rolle endogener Peptide beim Wachstum und der Ausbreitung von Krebszellen. In enger Zusammenarbeit mit den Bereichen A und B entwickeln Projekte in Bereich C neuartige Werkzeuge und Methoden, um die Aktivität und Stabilität bioaktiver Peptide zu optimieren. Die zweite Technologieplattform ermöglicht Untersuchungen zur Verteilung, Verträglichkeit und Bioverfügbarkeit von Peptiden in präklinischen Tiermodellen. Der Forschungsverbund eröffnet ein neues Forschungsfeld, um Einblicke in die Rolle körpereigener Peptide bei infektiösen und onkologischen Prozessen zu erhalten. Das ultimative Ziel ist es, diese Ergebnisse in neuartige bildgebende und liefernde Werkzeuge und Therapeutika auf Peptidbasis umzusetzen.
