Two asteroid bodies. H&E stain.

An asteroid body, is a microscopic finding seen within the giant cells of granulomas in diseases such as sarcoidosis and foreign body giant cell reactions.^[1]

There is controversy about what they are composed of. Traditionally, they were thought to be cytoskeletal elements and to consist primarily of vimentin.^[2] However, more recent research suggested that that was incorrect and that they may be composed of lipids arranged into bilayer membranes.^[3]

They were also once thought to be related to centrioles,^[4] an organelle involved in cell division in eukaryotes.

BACKGROUND: Sporotrichosis is one of the most common subcutaneous mycoses in Venezuela. It is a granulomatous chronic infection with cutaneous or subcutaneous tissue lesions. Regional lymphatic involvement may be present; extracutaneous disease is rare. The causal fungus Sporothrix schenckii has bee

It is widely assumed that our mammalian ancestors, which lived in the Cretaceous era, were tiny animals that survived massive asteroid impacts in shelters and evolved into modern forms after dinosaurs went extinct, 65 Ma. The small size of most Mesozoic mammalian fossils essentially supports this vi

The Cretaceous-Paleogene (K-Pg) boundary is marked by a major mass extinction, yet this event is thought to have had little effect on the diversity of lizards and snakes (Squamata). A revision of fossil squamates from the Maastrichtian and Paleocene of North America shows that lizards and snakes suf

… The problem is treated as an example of a restricted three-body problem that consists of an asteroid, Sun, and Jupiter. … Jupiter is treated as a perturbation on the asteroid-Sun two-body problem. … We found that the eigenstate of the Liouvillian of this two-body problem has a threefold degeneracy at the resonance point inside the Kirkwood gaps. …
