News Medical: Mitochondria and peroxisomes work together to defend against cell damage
The new study implicates cellular parts called peroxisomes as important alternative heat producers in brown fat. Peroxisomes are small compartments in cells involved in processing fat molecules. When ...
Peroxisomes are cytoplasmic organelles that catalyse the breakdown of very long chain fatty acids through beta-oxidation. Peroxisomes also have an important role in generating and degrading reactive ...
The lysosome is delivered material for degradation via transient interactions or complete fusion, forming endolysosomes and autolysosomes respectively. This way, the lysosomes act as reservoirs for acidic hydrolases, cycling through fusion and fission events with late endosomes and autophagosomes.
The concept of the lysosome was introduced by Christian de Duve in 1955, who later won a Nobel Prize for his work. Lysosomes form from the Golgi apparatus and endosomes and are packed with over 50 different types of hydrolytic enzymes.
Lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms.
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.
Lysosome fusion and fission influence lysosome number, size and exocytosis [13, 14, 15]. Furthermore, depending on cellular metabolic requirements, or activation by distinct stimuli, lysosomes mobilize to either the cell periphery or to the perinuclear region [15].
The word “lysosome” is made up of two words “lysis” meaning breakdown and “soma” meaning body. It is an important cell organelle responsible for the inter and extracellular breakdown of substances.
