Exploiting the Human Peptidome for Novel Antimicrobial and Anticancer Agents
The goal of CRC 1279 is to discover endogenous human peptides that play key roles in the control of human pathogens and cancers and to optimize them for potential therapeutic applications. To achieve this, the CRC exploits the peptidome, i.e. the entirety of peptides in the human body. This source is of enormous interest because peptides govern numerous physiological and pathological processes. In addition, peptides are key regulators and effectors of innate and adaptive immunity and modulate the survival, growth and metastatic spread of cancer cells. Despite its importance, the human peptidome is functional hardly explored. The main reason for this is its enormous complexity, which makes purification of individual bioactive peptides challenging. In this CRC, we are utilizing comprehensive peptide libraries from human body fluids and tissues for the stepwise purification of endogenous bioactive compounds detected in specific fractions by repeated rounds of functional assays and separation. This approach allows to isolate bioactive peptides from mixtures of up to millions of naturally-occurring compounds. It has proven highly successful and allowed the discovery of numerous as-yet-unknown endogenous agents displaying antimicrobial (i.e. antiviral and antibacterial) and/or anticancer (e.g. antineoplastic and antimetastatic) activity. The framework of expertise and resources available in the CRC allows to define their mode of action and physiological relevance, and to apply state of the art technologies to optimize natural peptides for translational in vivo applications. Notably, a significant portion of endogenous peptides exerts both antimicrobial and antineoplastic activity and could be optimized for therapeutic development. The CRC is highly interdisciplinary and organized in three cooperative research areas that are supported by two essential technology platforms. The first core project generates and provides peptide libraries to the research projects and support them in peptide purification, synthesis, structural analysis and molecular modelling. Projects in area A discovered, characterized and optimized numerous antimicrobial peptides. Projects in area B analyzed the role of endogenous peptides in cancer growth and metastasis, focusing in particular on leukemic and cancer stem cells. In close cooperation with areas A and B, projects in area C develop novel tools and methodologies to optimize the activity, stability and delivery of the bioactive peptides. The CRC is complemented by a technology platform allowing testing of the distribution, tolerability and bioavailability of peptides in animal models. The research consortium opens a new, highly challenging field of research to obtain new insights into the role of endogenous peptides in infectious and oncological processes. It will clarify whether the generation of antimicrobial and antineoplastic peptides from abundant precursors by immune-activated proteases represents a common principle in innate immunity. The ultimate goal is to translate these results into novel peptide-based imaging and delivery tools and therapeutics.
