RNA granules, sites for the storage, transport, and regulation of RNA molecules within cells, are transported along axons and then translated locally, far from the cell body. Recent studies suggest that these granules can ...
Some of the most important tools in the toolbox of modern cell biologists are special chunks of DNA that act like spies, reporting on the cell's function. The markers, known as reporter genes, allow researchers to get a sense ...

(Medical Xpress)—As principal transformers of bacteria, organelles, synapses, and cells, vesicles might be said to be the stuff of life. One need look no further than the rapid rise to prominence of The international Society ...
University of Utah and German biologists discovered how nerve cells recycle tiny bubbles or "vesicles" that send chemical nerve signals from one cell to the next. The process is much faster and different than two previously ...

(Medical Xpress)—Neurons have developed elaborate mechanisms for transporting critical components, like transmitter-laden vesicles, down their axons to the synaptic terminations. An axon in a blue whale may be several meters ...
Two studies featuring research from Weill Cornell Medical College have uncovered surprising details about the complex process that leads to the flow of neurotransmitters between brain neurons -- a dance of chemical messages ...
