Inclusion bodies have a non-unit (single) lipid membrane [citation needed].Protein inclusion bodies are classically thought to contain misfolded protein.However, this has been contested, as green fluorescent protein will sometimes fluoresce in inclusion bodies, which indicates some resemblance of the native structure and researchers have recovered folded protein from inclusion bodies.
Examples of inclusions are glycogen granules in the liver and muscle cells, lipid droplets in fat cells, pigment granules in certain cells of skin and hair, and crystals of various types. [3] Cytoplasmic inclusions are an example of a biomolecular condensate arising by liquid-solid, liquid-gel or liquid-liquid phase separation.

Histological slide of the human herpes virus-6 showing infected cells, with inclusion bodies in both the nucleus and the cytoplasm. Inclusion bodies were first described in the late 19th and 20th centuries. One of the earliest figures associated with the discovery of inclusion bodies is Fritz Heinrich Jakob Lewy.
Pappenheimer bodies (Peripheral Blood / May-Grünwald Giemsa and Prussian blue stain) Pappenheimer bodies are abnormal basophilic granules of iron found inside red blood cells on routine blood stain. [1] They are a type of inclusion body composed of ferritin aggregates, or mitochondria or phagosomes containing aggregated ferritin. They appear ...
The Guarnieri bodies are found in all poxvirus infections and their presence is diagnostic. [4] The diagnosis of an orthopoxvirus infection can also be made rapidly by electron microscopic examination of pustular fluid or scabs. However, all orthopoxviruses exhibit identical brick-shaped virions by electron microscopy. [citation needed ...
Inclusion bodies often then appear in the cell nucleus and/or cytoplasm of the host cell. The inclusion bodies can first be identified by light microscopy in patient blood smears or stained sections of infected tissues. However, to fully characterize their composition, electron microscopy must be performed. Inclusion bodies may either be ...
Micrograph showing a Mallory body with the characteristic twisted-rope appearance (centre of image - within a ballooning hepatocyte). H&E stain. In histopathology, a Mallory body, Mallory–Denk body (MDB), or Mallory's hyaline is an inclusion found in the cytoplasm of liver cells. [1] Mallory bodies are damaged intermediate filaments within ...
