Ikoma, Japan - In neurons, changes in the size of dendritic spines - small cellular protrusions involved in synaptic transmission - are thought to be a key mechanism underlying learning and memory. However, the specific way in which these structural changes occur remains unknown. In a study published in Cell Reports, researchers from Nara Institute of Science and Technology (NAIST) have revealed that the binding of cell adhesion molecules with actin, via an important linker protein in the structural backbone of synapses, is vital for this process of structural plasticity.

Ikoma, Japan - Many natural compounds have various anti-inflammatory and other beneficial properties that humans have been utilizing for medicinal purposes for hundreds of years. However, the specific molecular mechanisms behind these health-promoting effects are not always clear. One such compound is 1 -acetoxychavicol acetate, or ACA, which comes from the tropical ginger
Alpinia plant. Now, researchers from Nara Institute of Science and Technology (NAIST) have identified how ACA can help in the treatment of inflammatory diseases.
