Receptors are generally transmembrane proteins, which bind to signaling molecules outside the cell and subsequently transmit the signal through a sequence of molecular switches to internal ...

Cell signalling is the mechanism by which stimuli are transmitted via a signalling cascade to effector molecules that orchestrate the appropriate response. Types of cell signalling pathways ...

In an effort to understand how brain cells exchange chemical messages, scientists say they have successfully used a highly specialized microscope to capture more precise details of how one of the most ...
