Reelin-Nrp1 interaction regulates neocortical dendrite development
Reelin exhibits a context-dependent function during brain development; however, its underlying mechanism is not well understood. Here, we found that neuropilin-1 specifically binds to the C-terminal region of Reelin and acts as a co-receptor for canonical Reelin-receptor. The Reelin-Nrp1 interaction is essential for proper dendritic development in superficial-layer neurons. This study provides evidence of the context-specific function of Reelin regulated by the C-terminal residues. (2020-10-15)

A bright idea -- Genetically engineered proteins for studying neurons using light
In neuroscience, tools for controlling the activation and deactivation of individual nerve cells are crucial to gain insights into their functions and characteristics. Now, scientists from Okayama University, Japan, have produced mutant variants of a membrane protein that can effectively silence neurons when illuminated. The silencing effect can be quickly ''toggled'' on and off using green and red light sequentially, providing a more sophisticated tool than those currently available. (2020-08-18)
