Definitions
- the present invention relates to a novel pharmaceutical use of an ⁇ -antigen derived from an acid-fast bacterium (Mycobacterium) or an analog thereof, or a gene encoding the same. More specifically, an atopic dermatitis, an asthma, an allergic rhinitis, an allergic disease can be obtained from an expression vector containing an alpha antigen derived from an acid-fast bacterium such as Mycobacterium kansasii or an analog thereof or a gene encoding the same. The present invention relates to a novel pharmaceutical use for preventing or treating allergic diseases such as conjunctivitis. Background art
- Allergic diseases such as atopic dermatitis, asthma, allergic rhinitis, and allergic conjunctivitis, show hypersensitivity to environmental antigens that do not respond to normal humans, and the destruction of organs by their own immune systems It is a disease that causes disability.
- the mechanism of the development of these diseases includes Th2 type cytokines, such as interleukin-4 and inta5 bitinkin-5, produced by Th2 cells among Th1 cells and Th2 cells involved in the cellular immune response to antigens. It is supposed to enhance allergic reactions (Progress in Medicine 17: 19-20, 1997). Elucidation of its induction and regulation mechanisms has important physiological and pharmacological implications, but no detailed mechanism has been elucidated.
- Th2 type cytokine predominant allergic state a Th1 type cytokine predominant
- the Th2 cells produce Th2 interferon-y power.
- interleukin-4 produced to increase IgE production
- interferon- ⁇ has been used for the treatment of allergic diseases (J. Am. Acad. Dermatol. 32: 684-685, 1991; Allergy 49: 120-128, 1994; Acta Derm. Venereol 73: 130-132, 1993), its effect is small and satisfactory results have not been obtained, and it has not been used clinically.
- Th2 type cytokines For the establishment of atopic disease, it is important to maintain the immune status predominantly of Th2-type cytokines and the sustained inflammatory response.
- attempts have been made to suppress site-in by immunosuppressants (Br. J. Dermatol. 143: 365-72, 2000; J. Allergy Clin. Immunol 106 (1 Pt2): S58-64, 2000), but did not lead to a fundamental improvement in immune status and had limited efficacy.
- the BCG vaccine is a vaccine using an attenuated strain of Mycobacterium bovis, and is the only live vaccine that has been recognized as a vaccine against Mycobacterium tuberculosis infection.
- BCG vaccines are used by many people today as safe vaccines because of their high adjuvant activity and very few side effects. At present, it has been reported that the BCG vaccine has the effect of shifting CD4 + helper T cells to Thl cells that produce interferon- ⁇ and interleukin-2 and are involved in cell-mediated immunity (Cancer Immunol. Iramunother. 39: 401-406, 1994; ibid. 40: 103-108, 1995).

- the a-antigen or the sperm antigen gene has not yet been elucidated for its mechanism of development. It is still unknown whether it is effective in the prevention or treatment of allergic diseases such as dermatitis and asthma. Further, as described above, it is thought that it is important to shift the Thl / Th2 type balance to a state where the Th2 type predominates for the establishment of an allergic disease, but only by shifting to the Thl cell side.
