抄録

The expression of p16(INK4a) has been reported to induce cell-cycle arrest and cellular senescence. The p16(INK4a) expression has never been examined in human mast cells and mastocytosis. We immunohistologically examined the expression of p16(INK4a) and tryptase in 5 normal human skin and 4 mastocytosis. In normal mast cells, only 5.9 ± 3.4 (mean ± standard deviation) % of tryptase-positive mast cells coexpressed p16(INK4a). However, significantly higher percentage (86.0 ± 14.1%) of tryptase-positive tumor cells was immunoreactive to p16(INK4a) in all of 4 mastocytosis. The p16(INK4a) overexpression may induce the senescence of neoplastic mast cells to undergo spontaneous regression of mastocytosis.
