Latest Microfilament Stories
Many cell types in higher organisms are capable of implementing directed motion in response to the presence of certain chemical attractants in their vicinity.
Revealing another part of the story of muscle development, Johns Hopkins researchers have shown how the cytoskeleton from one muscle cell builds finger-like projections that invade into another muscle cellâ€™s territory, eventually forcing the cells to combine.
With every bodily movementâ€”from the blink of an eye to running a marathonâ€”nerve cells transmit signals to muscle cells.
X-rays shed new light on the regulation of muscle contraction.
From grinding heavy metal to soothing ocean waves, the sounds we hear are all perceptible thanks to the vibrations felt by tiny molecular motors in the hair cells of the inner ear.
Many materials, when observed over a sufficiently long period of time, show changes in their mechanical properties.
New research sheds light on the interaction between the semi-flexible protein tropomyosin and actin thin filaments.
Scientists at Emory University School of Medicine have uncovered how a structural component inside neurons performs two coordinated dance moves when the connections between neurons are strengthened.
For the casual observer it is fascinating to watch the orderly and seemingly choreographed motion of hundreds or even thousands of fish, birds or insects.
Functioning much like gears in a machine, cellular motor proteins are critical to dynamic functions throughout the body, including muscle contraction, cell migration and cellular growth processes.
