title: Decreased natural killer cell activity in lichen ruber planus.
abstract: Natural killer cell (NK) activity of peripheral blood lymphocytes in 15 patients with moderate to exanthematic lichen ruber planus (LP) was studied. Markedly diminished NK response in patients with LP was revealed as compared with that of healthy controls. Decreased NK activity found in LP was supposed to be a secondary phenomenon.
