Expression of C4.4A and Haldisin in blistering skin lesions. C4.4A and Haldisin expression in blistering skin diseases are exemplified by staining of lesions affected at the sites of C4.4A (stratum spinosum) and Haldisin (stratum granulosum) expression. Panel (A) therefore shows C4.4A expression in pemphigus vulgaris and panel (B) shows Haldisin expression in pemphigus foliaceus. C4.4A (C) and Haldisin (D) expression patterns in Darier disease are also shown, where some overlap in localization is seen. Scale, (A, B), 25 µm; (C, D), 50 µm.
