Host-pathogen interactions are the dynamic, reciprocal biological processes that occur between a host organism and an invading pathogen, encompassing molecular recognition, immune sensing, signaling, and effector responses, as well as pathogen strategies for attachment, invasion, replication, and immune evasion. These interactions involve pattern recognition receptors (e.g., Toll-like, NOD-like, and RIG-I-like receptors), pathogen-associated molecular patterns, and downstream signaling pathways that regulate inflammation, cell death, and antimicrobial defenses. Concurrently, pathogens deploy virulence factors, secretion systems, and immune-modulatory molecules to manipulate host cell pathways, subvert immunity, and optimize their survival, replication, and transmission, thereby determining infection outcomes and disease pathogenesis.
There is evidence that nonhuman animals perceive the world, and how it unfolds in time, differently from humans and from each other. For example, certain beetles can see flickering in lights up to around 500 Hz, while in ...
A research team at the University of Greifswald's Research Training Group RTG-PRO "Proteases in pathogen and host: importance in infection and inflammation" has discovered a new mechanism by which bacterial pathogens adjust ...
