Definitions
- the present invention relates to a drug for treating allergic contact dermatitis. Background technology ''
- epidermal cells play an important role in allergic dermatitis.
- epidermal keratinocytes are activated by stimulation with antigens and chemicals, and produce various cytokins such as granulocyte / macrophage colony-stimulating factor (GM-CSF) (Lee et al; JI thigh unol , 159: 5084-5088 (1997) and Steinhoff et al; Curr Opin Allergy Clin Immunol, 1: 469-476 (2001)).
- GM-CSF granulocyte / macrophage colony-stimulating factor
- the generated cytodynamics activates the Langerhans cells, which are antigen-presenting cells (Katz et al: Nature, 282: 324-326 (1979)), and the activated Langerhans cells migrate to the associated lymph node. Presents antigen to naive T lymphocytes (Kripke et al: J Immunol, 145: 2833-2838 (1990) and Banchereau et al: Annu Rev Immunol, 18: 767-811 (2000)).
- GM-CSF has been reported in patients with atopic dermatitis (Pastore et al: J Clin Invest, 99: 3009-3017 (1997)), and GM-CSF derived from epidermal keratinocytes is Langerhans Acts on cells and enhances their immune stimulatory function (Witmer-Pack et al: J Exp Med, 166: 1484-1498 (1987), Heufler et al: J Exp Med, 167: 700-705 (1988), Salgado et al.
- ERK extracellular regulated kinase
- MAPKs mitogen-activated protein kinase
- MAPK kinases via MEK1 / 2 through ERK1 / 2, MKK7 and MKK4 / SEK1 via JNK, and MKK3 / 6 through p38.
- ERK and p38 The interaction between ERK and p38 is discussed in detail in the section on DNA synthesis in rat lung myofibroblasts by cell growth stimulation and ERK1 / 2.
- Activation is enhanced by the selective inhibitor of p38, SB203580 (Rice et al: Am J Respir Cell Mol. Biol, 27: 759-765
- GM-CSF produced via MEK / ERK suppresses the induction of Thl involved in allergic contact dermatitis. Therefore, atopic dermatitis and contact dermatitis are clearly different in their pathogenesis, and the development of therapeutics for them had to be carried out from a completely different viewpoint. Disclosure of the invention
- an object of the present invention is to provide a remedy for allergic contact dermatitis. It is in.
- the present inventor conducted various studies to search for a therapeutic agent effective for allergic contact dermatitis.
- MEK / ERK acts antagonistically with p38, Although the drug was thought to be effective for atopic dermatitis, it was not expected to be effective for contact dermatitis.
- the present inventors have found that a mouse picryl chloride-induced dermatitis model, which is widely used as a drug, exhibits an excellent therapeutic effect, and thus completed the present invention.
- the present invention provides a remedy for allergic contact dermatitis comprising a substance having a MEK inhibitory activity as an active ingredient.
- the present invention provides use of a substance having an MEK inhibitory activity for producing a therapeutic drug for allergic contact dermatitis.
