Acroeimeria
''Acroeimeria'' is a genus of parasites that contains those species which initially develop immediately beneath the brush-border of the intestinal epithelium, but the meronts and gamonts of which are early on extruded to form a layer on the surface of the gut mucosa. Morphologically they are similar to the ''Eimeria'' to which they are closely related. The genus was described in 1989 by Paperna and Landsberg. General features The defining feature of this genus is their development, after becoming enclosed by extensions of the host cell membrane, within the resulting parasitophorous 'sack' which bulges out above the surface of the intestinal mucosa. This pattern of development is not known to occur in birds or mammals but is common in fish. The endogenous development of the parasite is intra-cytoplasmic, within the epithelial cells of the ileum. The parasites lie above (closer to the lumen) the host cell nucleus. Below the parasitophorous vacuole, the host cytoplasm expands as th ...

Nucleolus
The nucleolus (, plural: nucleoli ) is the largest structure in the nucleus of eukaryotic cells. It is best known as the site of ribosome biogenesis, which is the synthesis of ribosomes. The nucleolus also participates in the formation of signal recognition particles and plays a role in the cell's response to stress. Nucleoli are made of proteins, DNA and RNA, and form around specific chromosomal regions called nucleolar organizing regions. Malfunction of nucleoli can be the cause of several human conditions called "nucleolopathies" and the nucleolus is being investigated as a target for cancer chemotherapy. History The nucleolus was identified by bright-field microscopy during the 1830s. Little was known about the function of the nucleolus until 1964, when a study of nucleoli by John Gurdon and Donald Brown in the African clawed frog ''Xenopus laevis'' generated increasing interest in the function and detailed structure of the nucleolus. They found that 25% of the frog e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
