Neutrophilic inflammation in the respiratory mucosa predisposes to RSV infection


Even with intimate exposure to a virus, some people fail to become infected. Variable transmission partly depends on the dose and duration of exposure but is also governed by the immune status of the host, such as the presence of specific protective antibodies or T cells. However, for some infections, the reasons for erratic transmission are largely unknown. For example, respiratory syncytial virus (RSV) can repeatedly reinfect individuals throughout their lives despite the presence of specific immunity. Additionally, antibodies and T cells have limited efficacy against newly emergent pathogens with pandemic potential. However, the intrinsic and innate mechanisms underlying protection when people are exposed to these viruses are poorly understood.
