title: E-selectin expression in salivary endothelial cells and sera from patients with systemic sclerosis. Role of resident mast cell-derived tumor necrosis factor alpha.
abstract: OBJECTIVE
  To assess endothelial cell activation in patients with systemic sclerosis (SSc).
  
  
  METHODS
  Concomitant study of salivary gland biopsy tissues and sera for expression of E-selectin and its potent activator tumor necrosis factor alpha (TNF alpha), using immunostaining and enzyme-linked immunosorbent essay.
  
  
  RESULTS
  E-selectin was overexpressed in SSc patients, but not in controls. TNF alpha was detected in mast cells.
  
  
  CONCLUSIONS
  Mast cell-derived TNF alpha may contribute to endothelial cell activation in SSc.
