High Prevalence of Influenza A (H1N1 and H3N2) Infection in South Iran [PDF]
Disease and Diagnosis, 2023 Background: Influenza A is divided into a number of subtypes, the most common of which are circulating H3N2 and H1N1. Influenza A and B viruses, which normally circulate in humans (human influenza viruses), are responsible for seasonal influenza ...

Human Properdin Released By Infiltrating Neutrophils Can Modulate Influenza A Virus Infection
Frontiers in Immunology, 2021 The complement system is designed to recognise and eliminate invading pathogens via activation of classical, alternative and lectin pathways. Human properdin stabilises the alternative pathway C3 convertase, resulting in an amplification loop that leads ...
