based on remarkable similarities between the central nervous system and the immune system [ e. g. , both systems have memory cells , both appear to have identical receptors for dopamine , acetylcholine , enkephalins , endorphins , sharing of antigenic determinants on one or another cns cell and one or another type of immunocyte cell , both systems communicate by soluble substances ( e.g. , neurotransmitters and lymphokines , respectively ) ] , we have postulated that some forms of alzheimer 's disease are due not to cns cell death but rather to excess suppression of the brain `` '' b-cell equivalent '' '' .
