Abstract

The source of the -a that mediates EAE could be either inside the brain or from peripheral tissues. If originating in the periphery, -a would have to cross the altered BBB. Our previous work (8) has demonstrated that murine -(x crosses the BBB by a saturable transport system different from the systems identified for interleukins (2, 3). - a crosses as an intact molecule to appear in both the parenchyma of the brain the cerebrospinal fluid (8). This raises the question of the role the transport system for -(x plays in EAE.
