Russell bodies are inclusion bodies usually found in atypical plasma cells that become known as Mott cells. [1] Russell bodies are eosinophilic, homogeneous immunoglobulin (Ig)-containing inclusions usually found in cells undergoing excessive synthesis of Ig; the Russell body is characteristic of the distended endoplasmic reticulum. Russell ...
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.
Plasma cells with Dutcher and Russell bodies (H&E stain, 100×, oil) Plasma cells are large lymphocytes with abundant cytoplasm and a characteristic appearance on light microscopy. They have basophilic cytoplasm and an eccentric nucleus with heterochromatin in a characteristic cartwheel or clock face arrangement.
Bizarre cells, which are multinucleated; Mott cells, containing multiple clustered cytoplasmic droplets or other inclusions (sometimes confused with Auer rods, commonly seen in myeloid blasts) Flame cells, having a fiery red cytoplasm [71] [72] Historically, the CD138 has been used to isolate myeloma cells for diagnostic purposes.
Reactive lymphocyte surrounded by red blood cells. In immunology, reactive lymphocytes, variant lymphocytes, atypical lymphocytes, Downey cells or Türk cells are cytotoxic (CD8 +) lymphocytes that become large as a result of antigen stimulation. Typically, they can be more than 30 μm in diameter with varying size and shape.
Hydrogen sulfide is produced in small amounts by some cells of the mammalian body and has a number of biological signaling functions. Only two other such gases are currently known: nitric oxide (NO) and carbon monoxide (CO). The gas is produced from cysteine by the enzymes cystathionine beta-synthase and cystathionine gamma-lyase.
Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into ATP, and then release waste products. [1] Cellular respiration is a vital process that occurs in the cells of all [[plants and some bacteria ]].
Gaseous signaling molecules are gaseous molecules that are either synthesized internally (endogenously) in the organism, tissue or cell or are received by the organism, tissue or cell from outside (say, from the atmosphere or hydrosphere, as in the case of oxygen) and that are used to transmit chemical signals which induce certain physiological or biochemical changes in the organism, tissue or ...
