Abstract:
A method for inhibiting the expression of CCL27/CTACK(Cutaneous T-cell-attracting chemokine) is provided to regulate SPC(sphingosylphosphorylcholine) inducing expression of CCL27/CTACK, so that the method is useful for prevention and treatment of diseases associated with overexpression of CCL27/CTACK including atopic dermatitis, psoriasis and inflammatory skin disease. The expression of CCL27/CTACK is inhibited by administering an effective amount of sphingosylphosphorylcholine regulator capable of inhibiting activity of SPC or competing with the mechanism of SPC inducing overexpression of CCL27/CTACK to a mammal requiring the expression reduction of CCL27/CTACK. A method for screening the SPC regulator comprises the steps of: (1) treating a testing cell such as keratinocyte with 2-10 muM of SPC or its derivatives to induce overexpression of CCL27/CTACK; and (2) treating the overexpression of CCL27/CTACK-induced cell with a candidate material and measuring the expression inhibition of CCL27/CTACK. Further, the mammal has an atopic dermatitis or psoriasis.
