In pneumoniae of other origins, such as infections with respiratory syncytial virus in children (Gu et al., 2016), H5N1 (Zou et al., 2014) or H7N9 (Huang et al., 2014; Yang et al., 2015) in adults, small-scaled studies had previously shown increased levels of Ang II in the serum of infected patients, especially in the acute phase of the disease, and that Ang II levels may be associated with disease progression. The gene discussed is AGT; the disease is infection.
