Abstract: The present invention relates to the diagnosis, the prevention and the treatment of demyelinating disorders of the central nervous system (CNS), in particular disorders exhibiting altered levels of antibodies directed against ?1-3-galactose, such as multiple sclerosis (MS) and clinically isolated syndrome (CIS).

Abstract: Methods are provided for determining whether a subject has a graft tolerant phenotype. In practicing the subject methods, the expression of at least one gene in a sample from the subject, e.g., a blood sample, is assayed to obtain an expression evaluation for the at least one gene. The obtained expression evaluation is then employed to determine whether the subject has a graft tolerant phenotype. Also provides are compositions, systems and kits that find use in practicing the subject methods. The methods and compositions find use in a variety of applications, including the determination of an immunosuppressive therapy regimen.

Abstract: The present invention relates to a method for detecting the presence or the absence, and optionally quantifying and/or isolating, antigen-specific peripheral blood mononuclear cells. This method, which involves flow cytometry, is based on the use of a fluorescently-labeled antibody specifically recognizing peripheral blood mononuclear cells, and of fluorescently-labeled beads coated with at least one antigen that is specifically recognized by antigen-specific peripheral blood mononuclear cells. The method according to the invention is for example useful for diagnosing immune disorders such as transplant rejections and autoimmune disorders.

Abstract: The invention relates to a method for determining a risk of permanent rejection of a graft after being transplanted to a recipient, said method being characterized in that it includes the following steps: (a) entering physiological/clinical characteristics of the recipient and the donor into a computation unit by means of an input interface, said characteristics including the gender of the recipient, the creatinine level of the graft donor when sampled, the age of the recipient at the time of the transplant,—the number of renal transplants previously received by the recipient,—a creatinine level of the recipient measured twice at at least one predetermined point in time after the transplant, a proteinuria level of the recipient measured at a predetermined point in time after the transplant, and the existence of an episode of permanent rejection of the transplant during the first year of the transplant; (b) determining the parameters on the basis of said characteristics; (c) combining said parameters so as to

Abstract: Stable polyligands are provided by preparing fused proteins, where the fused protein comprises a ligand at one terminus and a subunit of a multimeric unit protein at the other terminus, where the fused protein is able to assemble to provide a polyligand. The polyligands find use in modulating physiological processes by inhibiting ligand induced signal transduction by surface membrane protein receptors and/or in the case of .mu. chain use, by complement mediated killing or any other effector functions. The molecule may be composed solely, of human components to avoid an immune response by the recipient.
