title: Interleukin-10 as a CNS therapeutic: the obstacle of the blood-brain/blood-spinal cord barrier.
abstract: Interleukin (IL)-10 exerts beneficial effects on the central nervous system (CNS) after peripheral administration, but its penetration across the blood-brain barrier (BBB) has not been quantified. We show that 125I-IL-10 is stable in circulating blood but does not cross the intact BBB after intravenous delivery. Thus, peripheral IL-10 probably can serve as a CNS therapeutic only when the BBB is disrupted.
