DNA vaccination for treatment of autoimmune disease

A pro-inflammatory T cell response is specifically suppressed by the injection into a recipient of DNA encoding an autoantigen associated with autoimmune disease. The recipient may be further treating by co-vaccination with a DNA encoding a Th2 cytokine, particularly encoding IL4. In response to the vaccination, the proliferation of autoantigen-reactive T cells and the secretion of Th1 cytokines, including IL-2, IFN-γ and IL-15, are reduced.

Adjuvant therapy

Methods are provided for the treatment of allergic and other immune disorders associated with overproduction of Th2 type cytokines by antigen specific T cells. Immunotherapy with adjuvants, as provided in the present invention, greatly inhibits the development of airway hyperreactivity and airway inflammation. Such immunotherapy is shown to reverse ongoing airway disease, and convert allergic inflammatory responses into protective immune responses. Conditions of particular interest include allergic conditions associated with production of Th2 cytokines and / or IgE antibodies, asthma, allergic rhinitis, and anaphylactic reactions. The addition of adjuvant induces a Th1-type immune response and can redirect an established Th2-type response to a Th1-type response for the selected antigen. Preferably, antigen-specific IgE production is reduced without altering the intensity of the antigen-specific proliferative response. One particularly preferred adjuvant for use in accordance with the present invention is a Listeria adjuvant.

The invention discloses a function of voltage-gated proton channel Hv1 protein in the production of allergic asthma, an established good allergic asthma mouse model, and belongs to the field of medical science. By studying the Hv1 protein, through the comparison with a wild-type C57 (WT) mouse, it is found that the level of allergic airway inflammation in an Hv1 gene knockout mouse (KO) after sensitization and stimulation with ovalbumin (OVA) is significantly higher than that of a control group, that is to say, the Hv1 gene knockout mouse suffers from the allergic asthma. After serum, a bronchoalveolar lavage fluid (BALF) and the pulmonary histopathology are inspected, it is found that Hv1 deficiency significantly promotes the recruitment of OVA-induced inflammatory cells, the level of Th2cytokines of the allergic asthma mouse is increased, and the production of mucus secretion in the allergic asthma mouse is promoted. Through further experiments, it is found that the Hv1 deficiency significantly reduces the expression of NOXs, the results indicate that Hv1 gene knockout increases the prevalence of the allergic asthma by suppressing the yield of ROS. According to the function of the Hv1, the voltage-gated proton channel Hv1 protein can be used for preparing drugs for preventing, alleviating and / or treating the allergic asthma.
