The blood brain-barrier and its role in Alzheimer’s disease – an update to the KsD page
The human brain is an extremely sensitive organ. Therefore, it must also be particularly protected from toxins and pathogens. The supply of messenger substances and the removal of metabolic products must also be precisely regulated. The blood-brain barrier (BBB) has exactly this function and separates the central nervous system from the rest of the body's blood circulation. The BBB acts as a shield, protecting the brain from infectious agents and toxic substances, but must also act as a filter, allowing nutrients to get inside the central nervous system.
