Researchers at Brown University have discovered that hemifusion, a critical step in membrane fusion, allows vesicles to share membranes without releasing their contents. This stable state enables the rapid delivery of drugs to target cells by controlling the timing of fusion.
Irene Chen's research on protocells and RNA-based systems has led to a deeper understanding of the emergence of cellular behavior. Her work promises exciting insights into the origins of biological complexity, suggesting that evolving higher levels of organization might have been surprisingly easy during the origin of life.
Researchers used a flash-freeze physical-fixation technique to study nematode worms and found that membrane packets of neurotransmitter localize in new places. The technique provides an accurate picture of where synaptic proteins cluster, information previously unknown to scientists.
A Rice University study has identified the complexin protein as a brake that shortens response time for signal transmission in nerve cells, enabling nearly instantaneous passing of information. This breakthrough sheds light on the mechanisms behind rapid neural signaling.
Scientists have visualized individual synaptic vesicles and proteins using Stimulated Emission Depletion (STED) microscopy, resolving the diffraction barrier. They found that synaptotagmin molecules remain together after fusion, enabling efficient neurotransmitter release.
Researchers have developed an assay that visualizes the formation of clathrin-coated vesicles at single clathrin-coated pits with high time resolution. This breakthrough sheds light on fundamental questions about clathrin-mediated endocytosis, including whether single coated pits give rise to multiple vesicles.
Researchers modelled and simulated motor traffic to determine optimal conditions for nanocargo transport in biomimetic systems. The study found that increasing the number of motors while avoiding traffic jams is crucial for efficient cargo transport.
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.
Clathrin-coated vesicles are responsible for transporting proteins from the outside of the cell inside. The new insights into their formation help build a picture of the overall process and suggest possible targets for future therapeutic intervention.
