d.ainage of central nervous system(CNS) antigens to the brain-d.aining cervical lymph nod.s(CLN) is likely crucial in the initiation and.control of autoimmune responses d.ring multiple sclerosis(MS).We d.monstrate neuronal antigens within CLN of MS *** monkeys and.mice with experimental autoimmune encephalomyelitis(EAE) and.in mouse mod.ls with non-inflammatory CNS d.mage,the type and.extent of CNS d.mage was associated.with the frequencies of CNS antigens within the cervical lymph *** ad.ition,CNS antigens d.ained.to the spinal-cord.d.aining lumbar lymph *** human MS CLN,neuronal antigens were present in pro-inflammatory antigen-presenting cells(APC),whereas the majority of myelincontaining cells were *** may reflect a d.fferent origin of the cells or d.fferent d.ainage ***,neuronal antigen-containing cells in human CLN d.d.not express the lymph nod. homing receptor CCR7,whereas myelin antigen-containing cells in situ and.in vitro ***,CLN from EAE-affected.CCR7-d.ficient mice contained.equal amounts of myelin and.neuronal antigens as wild.type *** conclud. that the type and.frequencies of CNS antigens within the CLN are d.termined.by the type and.extent of CNS ***,the presence of myelin and.neuronal antigens in functionally d.stinct APC populations within MS CLN suggests that d.fferential immune responses can be evoked.
