NK cells, slanDCs, and neutrophils colocalize in lesions of patients with psoriasis and Crohn disease. Immunohistochemistry was performed using sections from biopsies of skin from psoriasis patients (A) and intestine from Crohn disease patients (B). Double-staining analysis revealed that both DD2⁺ slanDCs and CD56⁺ NK cells were present in tissue samples of the 3 examined diseases and colocalized with CD15⁺ neutrophils. One representative experiment for each pathology (n = 5) is shown.
