Abstract: Compositions and methods for reducing or preventing graft-versus-host disease associated with allogeneic stem cell transplantation are described. A method includes harvesting hematopoietic cells from a patient with an immunologic disorder and harvesting hematopoietic cells from a donor. The harvested hemaptopoietic cells from the patient and the donor are mixed ex vivo for a period of time sufficient to activate lymphocytes within the hematopoietic cells harvested from the donor such that an immune reaction occurs and an activated portion and an unactivated portion is produced. A rhodamine B derivative is then added to the mixture of cells and the mixture is irradiated at a suitable wavelength and intensity for the selective destruction and/or inactivation of the activated portion without substantially affecting the unactivated portion or causing systemic toxicity in said patient. The irradiated cells are then infused into the patient.

Abstract: The present invention relates to the use of the photoactivable derivatives for the photodynamic treatment for the selective destruction and/or inactivation of immunologically reactive cells without affecting the normal cells and without causing systemic toxicity for the patient, wherein appropriate intracellular levels of said derivatives are achieved and irradiation of a suitable wavelength and intensity is applied.

Abstract: The present invention provides for methods of treating a cancer patient. In one methods, cancer cells are harvested from a patient. A therapeutic amount of a rhodamine derivative is then added to the harvested cancer cells. The harvested cells and the rhodamine derivative are then irradiated with a suitable wavelength and intensity for the selective killing of the cancer cells. The irradiated cancer cells are then mixed with antigen presenting cells to form a mixture. The mixture of cancer and antigen presenting cells are then injected into the patient. The present invention also provides for methods of inhibiting or treating an immunological disorder, infection, or a cancer in an individual.

Abstract: A polypeptide, the amino acid sequence of which comprises a sequence as set forth in SEQ ID NO:2, including at least one mutation within the degron domain of the polypeptide encompassed between positions 1 and 35 of the sequence, wherein said at least one mutation reduces the susceptibility of the polypeptide to ubiquitin-proteasome degradation.

Abstract: It is an object of the present invention to provide the clinicians with a new application for ligands specific to MHC-class I antigens, especially HLA-ABC antigens, this new application residing in the detection and diagnosis of endometriosis. It is also an object of the present invention to provide a method and a test kit for diagnosing endometriosis, preferably by immunohistochemistry, using a monoclonal anti- HLA-ABC antibody as a preferred ligand or diagnostic reagent. This new method is non-invasive and is more reliable as a screening test than the conventionally used laparoscopy. When the endometrium of a woman tests negatively with the claimed method, it prevents the use of laparoscopy which is an invasive method for detecting endometriosis. This method can be practised on a specimen obtained from the endometrium of a patient and does not require a specimen sampled directly from the endometriotic foci.
