vesicle Usage Examples

Converse of object

  • produce: They frequently produce large, swollen vesicles within the root tissues.
  • call: The synaptic terminal contains a number of small sacs, called synaptic vesicles.
  • form: The plasma membrane envelopes the particle and buds off to form an intracellular vesicle, the phagosome.
  • cause: Eventually virus particles enter the blood stream and are carried to different parts of the body where they cause secondary vesicles.
  • bind: Lysosomes - small membrane bound vesicles in the cytoplasm of cells which contain toxic enzymes.

Adjective modifier

  • synaptic: The synaptic terminal contains a number of small sacs, called synaptic vesicles.
  • secretory: The vacuole may then become a secretory vesicle that moves to the plasma membrane, where the contents can be discharged from the cell.
  • clathrin-coated: Several types of coated vesicles have been described, the best characterized of which are the clathrin-coated vesicles.
  • seminal: The pair of seminal vesicles secrete up to 85 % of the total volume of seminal fluid.
  • intracellular: The antigens are then processed in a series of intracellular acidic vesicles, called endosomes ( Fig.
  • coated: Several types of coated vesicles have been described, the best characterized of which are the clathrin-coated vesicles.

Modifies a noun

  • endocytosis: Biochem Soc Trans ( In Press ) Smillie KJ, Cousin MA ( 2005 ) Role of dynamin I phosphorylation in synaptic vesicle endocytosis.
  • recycling: We are currently examining the effect of loss and gain of Wnt function in synaptic vesicle recycling using FM dyes.
  • protein: This binding site is the synaptic vesicle protein 2A, believed to be involved in vesicle fusion and neurotransmitter exocytosis.
  • transport: Our aim is to use these virus-host cell interactions to investigate fundamental aspects of cell biology, such as vesicle transport and secretion.
  • trafficking: It is therefore, likely that defects in synaptic vesicle trafficking may be associated with specific sub-forms of schizophrenia.

Noun used with modifier

  • lipid: The white dot is probably a lipid vesicle that has not unrolled.
  • membrane: However, membrane vesicles need not be present at the beginning of translation.
  • gas: Gas vesicles are hollow cylindrical tubes, closed by a hollow, conical cap at each end.
  • transport: Very many species produce similar spherical BS of about 0.5 micron in diameter with characteristic latticework surface, looking like giant clathrin-coated transport vesicles.
