Droplet organelles?
Cells contain numerous, molecularly distinct cellular compartments that are not enclosed by lipid bilayers. These compartments are implicated in a wide range of cellular activities, and they have been variously described as bodies, granules, or organelles. Recent evidence suggests that a liquid-liquid phase separation (LLPS) process may drive their formation, possibly justifying the unifying te...
متن کاملExocyst-Positive Organelles and Autophagosomes Are Distinct Organelles in Plants.
Autophagosomes are organelles that deliver cytosolic proteins for degradation in the vacuole of the cell. In contrast, exocyst-positive organelles (EXPO) deliver cytosolic proteins to the cell surface and therefore represent a form of unconventional protein secretion. Because both structures have two boundary membranes, it has been suggested that they may have been falsely treated as separate e...
متن کاملMitochondria--the suicide organelles.
One of the near-to-invariant hallmarks of early apoptosis (programmed cell death) is mitochondrial membrane permeabilization (MMP). It appears that mitochondria fulfill a dual role during the apoptotic process. On the one hand, they integrate multiple different pro-apoptotic signal transducing cascades into a common pathway initiated by MMP. On the other hand, they coordinate the catabolic reac...
متن کاملLysosome-related organelles.
Lysosomes are membrane-bound cytoplasmic organelles involved in intracellular protein degradation. They contain an assortment of soluble acid-dependent hydrolases and a set of highly glycosylated integral membrane proteins. Most of the properties of lysosomes are shared with a group of cell type-specific compartments referred to as 'lysosome-related organelles', which include melanosomes, lytic...
متن کاملOrganelles in parallel
Learn more when your neighbors do S ynaptic neighbors help each other learn, according to Christopher Harvey and Karel Svoboda (HHMI, Chevy Chase, MD). Learning and memory, which require a strengthening of synaptic connections known as long-term potentiation (LTP), have traditionally been thought to be synapse specifi c, with one synapse unable to infl uence LTP induction in even its closest ne...
