Downie bodies
Downie Bodies
Downie bodies (pronounced: /ˈdaʊni/), also known as Downie's inclusion bodies, are a type of inclusion body found in the cytoplasm of cells infected with certain types of viruses. They were first described by the Scottish pathologist Alexander Downie in 1931.
Etymology
The term "Downie bodies" is derived from the name of Alexander Downie, who first identified these structures. The term "body" is used in the biological sense to refer to a distinct structure within a cell.
Description
Downie bodies are small, round or oval structures that are visible under a microscope. They are typically found in the cytoplasm of infected cells, but can also be found in the nucleus. They are composed of viral proteins and genetic material, and are thought to be involved in the replication of the virus.
