Sometimes it is hard to imagine how many molecules are involved in a common biological pathway but there are thousands of molecules that orchestrate their chemical reactions to sustain life. One such area is the synaptic gap where messages are passed between neurons. This is a very active space where vesicle with messengers cross the membrane barrier to the other neurons through vesicles. But within the cell at that location, there are multiple molecules involved that can be visualized. This help understand how difficult is drug discovery wherein binding of a small molecule can change this delicate balance of many interacting proteins towards the desired outcome.
