Gernot Posselt

Gernot Posselt is a researcher in the Department of Molecular Biology at the University of Salzburg, specializing in immunology and molecular biology with a focus on Helicobacter pylori pathogenesis, proteolysis, and gastric cancer mechanisms. His work bridges microbiology, immunology, and cancer research, contributing to our understanding of bacterial virulence factors and host-pathogen interactions.

His research interests include:

• Helicobacter pylori pathogenesis and its role in gastric cancer development
• Proteolysis mechanisms in bacterial infections
• TLR signaling and cytokine regulation in immune responses
• SOCS protein function as feedback inhibitors in immune pathways
• Antimicrobial peptide design and characterization

Posselt's publication record demonstrates a strong trajectory in understanding the molecular mechanisms of bacterial pathogenesis, particularly focusing on Helicobacter pylori and its interactions with host cells. His more recent work has expanded into computational approaches for antimicrobial peptide design, showing interdisciplinary reach across molecular biology, bioinformatics, and drug discovery. The research shows consistent collaboration with Silja Wessler's group and other international researchers.

His scientific contributions have been recognized through publications in reputable journals including ACS Chemical Biology, Small, PLoS ONE, and Journal of Immunology.
