Abstract: Disclosed are novel compositions, methods and vaccines, which upon administration to a patient suffering from a melanoma, colon carcinoma tumor or breast cancer, postpone and/or reduce the need for chemotherapy treatment, slow the progression of or eliminate the tumor and/or alleviate the symptoms of the tumor. The compositions comprise stressed colon carcinoma, melanoma or breast cancer cells, preferably autologous such cells.

Abstract: The present invention provides methods for increasing expression of cell surface molecules of CD5+ B cell lymphoma cells by contacting cells with immune response modifiers. The invention also provides methods for the treatment of CD5+ B cell lymphomas, including chronic lymphocytic leukemia and small lymphocytic lymphoma, by administering immune response modifier compounds to a subject in need of such treatment. Suitable immune response modifier compounds include agonists of TLR7 and/or TLR8.

Abstract: The development of graft versus host disease in a mammalian patient undergoing cell transplantation therapy for treatment of a bone marrow mediated disease, is prevented or alleviated by subjecting at lest the T-cells of the allogeneic cell transplantation composition, in admixture with red blood cells of the donor, extracorporeally, to oxidative stress, in appropriate dosage amounts, such as bubbling a gaseous mixture of ozone and oxygen through a suspension of the T-cells. The process may also include irradiation of the cells with UV light, simultaneously with the application of the oxidative stress. The oxidative stress induces reduced inflammatory cytokine production and a reduced proliferative response in the T-cells.
