p53 accumulation in polynuclear-giant-cells.

Abstract excerpt

Accumulation of p53 has been reported in nearly all malignant human tumours. Macrophage derived giant cells of sarcoid granulomas in human lung tissue also show intense staining for p53 while normal alveolar macrophages remain unstained. Since sarcoid giant cells are not considered to be either pre-neoplastic nor to exhibit p53 gene mutations, two different physiological functions of p53 may be illustrated....
