title: [Flavonoids from Diospyros kaki inhibit the adhesion between lymphocyte and dorsal root ganglion].
abstract: OBJECTIVE
  To investigate the effects of flavonoids from the leaves of Diospyros kaki L (FLDK) on the adhesion between the lymphocyte and the neurone.
  
  
  METHODS
  Centrifugal assay for fluorescence-bsaed cell adhesion was used to assay the adhesion between the lymphocyte and the dorsal root ganglion (DRG).
  
  
  RESULTS
  The adhesion was significantly suppressed in the presence of FLDK dose-dependently at 5, 25 microg/mL concentration. FLDK was also effective to inhibit the adhesion under the challenge of ICAM-1 by 28.5% and 50.1%, respectively. Furthermore, FLDK enforced the inhibition of anti-NCAM antibody on the lymphocyte adhesion to DRG cells.
  
  
  CONCLUSIONS
  FLDK might contribute to the prevention and treatment of the inflammation injury under neuron insult such as ischemia/reperfusion, neurotrauma and other neurodegenerative disease by inhibiting the adhesion between lymphocytes and neurons.
