Figure 1. Frequency of CD4+CD30+ T cells after stimulation. A: Representative dot plots of peripheral blood mononuclear cells (PBMCs) stimulated with Dermatophagoides pteronyssinus (Der p) or Phorbol myristate acetate (PMA) in patients with vernal keratoconjunctivitis (VKC). B: Comparative histograms of CD30 frequency on CD4+ gated cells. Dot plots and histograms are representative from 17 patients with VKC.
