Page 5: Research news on Host-Pathogen Interactions

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.

One of cholera's great enemies is found in the human gut

Cholera-causing bacteria are locked in an evolutionary arms race with a viral nemesis, according to a new genomic study. Researchers have found that, in the Ganges Delta, cholera bacteria rapidly gain and lose special armor ...

Viruses 'eavesdrop' on each other—but it can backfire

University of Exeter scientists studied chemical communication by phages (viruses that infect bacteria). The phages assessed in the study have two choices when they enter a cell: lie dormant or kill the cell and release new ...
