Fig. 3From: Inducible Nitric Oxide Synthase and Proinflammatory Cytokine Expression by Human Keratinocytes during Acute Urticaria CD23 expression in normal and pathological skin (A) CD23 is expressed at the mRNA level in pathological skin as shown by in situ hybridization with a specific probe for human CD23. (B) Immunohistochemistry with anti-CD23 moAb confirms CD23 expression in pathological skin of a patient with acute urticaria. (C) Negativity of the healthy skin of the same patient.
