Influenza virus particles
Influenza virus particles. Computer artwork of influenza (flu) virus particles. Each virus consists of a core of RNA (ribonucleic acid) genetic material surrounded by a protein coat. Embedded in the coat are surface proteins. There are two types of surface protein, haemagglutinin (H, orange) and neuraminidase (N, blue), and each exist in several subtypes. Both surface proteins are associated with the pathogenicity of the virus. Haemagglutinin binds to host cells, allowing the virus to enter them and replicate. Neuraminidase allows the new particles to exit the host after replication

EDITORS COMMENTS
This print showcases the intricate and deadly beauty of influenza virus particles. In this computer artwork, we witness the mesmerizing structure of these tiny pathogens that wreak havoc on our health. Each virus is composed of a core made up of RNA genetic material, encased within a protective protein coat. Embedded within this coat are two types of surface proteins: haemagglutinin (H) in vibrant orange and neuraminidase (N) in striking blue. These surface proteins play crucial roles in the pathogenicity of the virus. Haemagglutinin acts as a key, binding to host cells and facilitating viral entry for replication. Neuraminidase, on the other hand, enables newly formed viral particles to exit their host after replication. The complexity and diversity exhibited by these surface proteins cannot be understated. Multiple subtypes exist for both haemagglutinin and neuraminidase, contributing to the adaptability and virulence of different strains of influenza viruses. As we gaze at this awe-inspiring image, we are reminded not only of the immense scientific knowledge behind it but also its implications for medicine and public health. The study of such microcosmic entities allows us to better understand how these pathogens operate, aiding efforts in prevention, treatment, and control during flu outbreaks or potential pandemics like avian flu or bird flu. Science Photo Library has once again captured an extraordinary moment where art meets biology—a visual testament to our ongoing battle against infectious diseases.
