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.
A new evolutionary theory suggests that some asexual parasites may temporarily be able to infect a wider range of hosts as harmful genetic mutations build up. In a paper published in Trends in Parasitology, Cock van Oosterhout, ...
