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.
Polyhedral bodies were discovered by transmission electron microscopy in the cyanobacterium Phormidium uncinatum in 1956. [11] These were later observed in other cyanobacteria [12] and in some chemotrophic bacteria that fix carbon dioxide—many of them are sulfur oxidizers or nitrogen fixers (for example, Halothiobacillus, Acidithiobacillus, Nitrobacter and Nitrococcus; all belonging to ...
Segregation of toxic protein aggregates into JUNQ and IPOD inclusion bodies is a means by which mammalian cells can be rejuvenated through asymmetric division. [ 5 ] Thus, the discovery of JUNQ and IPOD provided a new striking perspective of how cells manage misfolded aggregated proteins and gave convincing proof that protein aggregation is a ...
Glycogen is an important energy source of the cell; therefore, it will be available on demand. The enzymes responsible for glycogenolysis degrade glycogen into individual molecules of glucose and can be utilized by multiple organs of the body. [4] [2] Lipids: Lipids, which are stored as triglycerides, are the common form of inclusions.
Chlamydia may be found in the form of an elementary body and a reticulate body. The elementary body is the nonreplicating infectious particle that is released when infected cells rupture. It is responsible for the bacteria's ability to spread from person to person and is analogous to a spore. The elementary body may be 0.25 to 0.30 μm in diameter.
I-cells, also called inclusion cells, are abnormal fibroblasts having a large number of dark inclusions in the cytoplasm of the cell (mainly in the central area). Inclusion bodies are nuclear or cytoplasmic aggregates of stainable substances, usually proteins. [1]
It was thought that compartmentalization is not found in prokaryotic cells., [1] but the discovery of carboxysomes and many other metabolosomes revealed that prokaryotic cells are capable of making compartmentalized structures, albeit these are in most cases not surrounded by a lipid bilayer, but of pure proteinaceous built.

There are at least two proteins that compose a cyanobacterium's gas vesicle: GvpA, and GvpC. GvpA forms ribs and much of the mass (up to 90%) of the main structure. GvpA is strongly hydrophobic and may be one of the most hydrophobic proteins known. GvpC is hydrophilic and helps to stabilize the structure by periodic inclusions into the GvpA ribs.
