Natural killer (NK) cells are innate lymphocytes that play a critical role in the early antiviral response, secreting effector cytokines and clearing infected cells. This review describes the role of Natural killer (NK) cells, a critical component of early antiviral immunity, in the establishment of tolerance to viral infections in natural hosts, as well as their role in the development of disease in nonnatural hosts. Altogether, it is believed that quick control of viral infections and reduced induction of pro-inflammatory cytokines have allowed bat viruses to rapidly co-evolve with their host without provoking major immuneThe careful study of the immune system in reservoirs of zoonotic diseases will certainly offer insights into how these animals carry high viral loads while remaining asymptomatic. ./cache/cord-333463-u7je0d1o.txt ./txt/cord-333463-u7je0d1o.txt
