In an oxazolone-induced allergic contact dermatitis model, CCR10 and CCR4, with their ligands, attracted tissue-resident memory T cells to inflamed skin; only simultaneous inhibition of CCL27, CCL17, or CCL22 prevent inflammation indicating redundance and compensatory roles of CCR10 and CCR4 in lymphocytes recruitment (44, 45). Here, CCL27 is linked to allergic contact dermatitis.
