Whereas, neither PMNs (identified by anti-neutrophil elastase, NE, Abs) nor platelets (stained using anti-CD41 and –CD42b) were readily detectable in healthy skin or isotype-stained samples, in psoriasis skin samples both cell types were present (Figures 3B,C and quantified in Figure 3D). This evidence concerns the gene ITGA2B and psoriasis.
