COMPOSITIONS AND METHODS FOR MODULATION OF SUPPRESSOR T CELL ACTIVATION

摘要

Methods of treating autoimmune disorders, coronary artery disease, allergy symptoms, allograft rejection sepsis/toxic shock are disclosed. Some methods comprise administering one or more regulatory compositions to activate the T suppressor cells by increasing the acetylation level and/or protein level of FOXP3 in combination with a T suppressor stimulus and/or an antigen. Some methods comprise administering one or more regulatory compositions to activate the T suppressor cells by increasing the acetylation level and/or protein level of FOXP3. Some methods comprise administering soluble GITR or antibodies that bind to GITR ligand. Methods of treating cancer, infectious diseases, and immune deficiency are also disclosed as are vaccination methods. The methods comprise administering one or more regulatory compositions to inactivate the T suppressor cells by reducing the acetylation level and/or protein level of FOXP3. Improved vaccines and vaccination methods are disclosed. Methods of identifying compounds that are useful to modulate acetylation level and/or protein level of FOXP3 and treat diseases are disclosed.
