How often are you getting colds? How strong is your immune system?
Traditionally, we are taught that the immune system’s job is to police the body and fight off infections.

A study from the February issue of Nature Neuroscience reveals something remarkable: one of the primary roles of immune cells in the brain is to help guide and stimulate the growth of new brain cells.
