title: The pathogenesis of demyelinating disease: insights from cell biology.
abstract: Cellular and humoral immune mechanisms have been implicated in the pathogenesis of human and experimental demyelinating diseases of the CNS. How these interact in the complex sequence of events that culminates in phagocytosis of myelin by macrophages has yet to be resolved. The relationship between leakage of the blood-brain barrier and demyelination, the reason why recurrent inflammatory demyelination occurs--seemingly in the absence of an antigen-specific immune response--and the lack of effective remyelination all require explanation if a coherent account of immunologically mediated demyelination is to be achieved. One approach to these problems is to study in vitro the developmental and cellular biology of oligodendrocytes--the glial cells responsible for the synthesis and maintenance of CNS myelin. This provides experimental opportunities not offered by more direct investigation of the intact nervous system, but carries the clear disadvantage that observations made in vitro cannot necessarily be extrapolated to humans.
