Our onboard computer, the brain, is a sterile environment separated from the immune system by the blood-brain barrier (BBB). Consequently, this is why the brain has its own resident immune cells, known as microglia. Microglia arise in the brain during embryonic development to evolve into self-renewing cells in later development and life. Despite this fact, overwhelming research suggests the brain is a part of the … Continue reading New role for white blood cells in the developing brain.
