New research by UT Southwestern scientists reveals complexity in organization of synaptic vesicles within individual synapses, challenging long-held assumptions about neurotransmitter release. Two distinct types of synaptic vesicles are found to be responsible for spontaneous and activity-dependent release, which may aid in understandi...
Researchers uncover the complexities of autophagy, a process that can promote or prevent cancer, depending on its timing. Autophagy also plays a crucial role in fighting infection and may hold clues to the mythical fountain of youth.
A new study found that Dap160 stabilizes the complex of molecules involved in vesicle formation and retrieval, allowing for continuous neurotransmitter release. This process is essential for neurons to communicate with each other.
Researchers at McGill University have identified 209 proteins involved in the cellular uptake process, shedding light on protein interactions and disease mechanisms. The study provides a comprehensive molecular inventory of clathrin-coated vesicles, with broad implications for various fields in biology and medicine.
Scientists have created giant wheel-shaped polyoxomolybdate molecules that associate and evenly distribute onto the surface of hollow spheres in dilute solution. Hydrogen bonds play a crucial role in this process, forming a 'glue' that overcomes electrostatic forces and holds the wheels in place.
Researchers found that adding clay to fatty acid micelles greatly accelerated vesicle formation, and even demonstrated growth and division in these physical-chemical systems. This discovery offers a possible pathway for the evolution of living cells, with implications for understanding the origins of life on Earth.
Researchers use multiphoton microscopy to watch cell membranes reshaping themselves into two-dimensional liquid phases, or 'rafts', and find that thermal energies influence membrane geometries. The study provides new insights into the functions of cell membranes and their importance to human health.
Researchers have made a breakthrough in understanding how proteins fold by capturing single proteins in action. The study reveals that protein molecules vary in the routes they take to form the same folded shape and create numerous intermediate shapes along the way.
Dartmouth Medical School biochemists identify a transport receptor that selects soluble proteins for export from cells, resolving a long-standing puzzle. The discovery opens up new avenues for understanding protein secretion and its role in diseases such as hemophilia.
Researchers at Virginia Tech found that proteins making up the Golgi apparatus are constantly being renewed, allowing potential new medical applications such as targeted medicine delivery. The discovery also suggests a method to modify cells to produce compounds for pharmaceuticals.
