1 Prions are proteins that can force conformational changes in natural proteins and seem to cause disease (kuru, new variant Creutzfeldt-Jakob disease, and fatal familial insomnia).  A virus is an obligate intracellular pathogen (meaning that it must live within the cells of its host in order to reproduce).
Neutrophils are the first line of defense at the site of an infection. They encounter and kill microbes intracellularly upon phagocytosis or extracellularly by degranulation of antimicrobial proteins and the release of Neutrophil Extracellular Traps (NETs).NETs were shown to ensnare and kill microbes.otably, neutrophils may also kill or inhibit extracellularly by releasing Neutrophil Extracellular Traps (NETs). NETs are fibers made of chromatin (histones and DNA) decorated with antimicrobial proteins. NETs ensnare and kill microbes, such as bacteria, fungi and parasites.
