Drainage of central nervous system(CNS) antigens to the brain-draining cervical lymph nodes(CLN) is likely crucial in the initiation and control of autoimmune responses during multiple sclerosis(MS).We demonstrate neuronal antigens within CLN of MS *** monkeys and mice with experimental autoimmune encephalomyelitis(EAE) and in mouse models with non-inflammatory CNS damage,the type and extent of CNS damage was associated with the frequencies of CNS antigens within the cervical lymph *** addition,CNS antigens drained to the spinal-cord-draining 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 different origin of the cells or different drainage ***,neuronal antigen-containing cells in human CLN did not express the lymph node homing receptor CCR7,whereas myelin antigen-containing cells in situ and in vitro ***,CLN from EAE-affected CCR7-deficient mice contained equal amounts of myelin and neuronal antigens as wild-type *** conclude that the type and frequencies of CNS antigens within the CLN are determined by the type and extent of CNS ***,the presence of myelin and neuronal antigens in functionally distinct APC populations within MS CLN suggests that differential immune responses can be evoked.
