Abstract: Disclosed is a method of inhibiting acute and chronic tissue transplant rejection in a subject with a tissue transplant. The method comprises the step of administering to the subject an effective amount of a compound represented by Formula (I): The values of the variables in Formula (I) are described herein.

Abstract: The invention provides novel methods of administering anti-CD3 antibodies, e.g., via oral or mucosal delivery. The invention also provides methods of treating, preventing, or delaying the onset of autoimmune disorders by oral or mucosal administration of anti-CD3 antibodies. Finally, the invention provides compositions including anti-CD3 antibodies, suitable for oral or mucosal administration.

Abstract: The invention relates to an MDR family P-glycoprotein located on human chromosome 7p15-21, polynucleotide sequences encoding this P-glycoprotein and fragments thereof. This gene is utilized in methods for assessing cancer cell susceptibility to therapies directed against multidrug resistance, and for the design of diagnostic and therapeutic methods relating to cancer multidrug resistance. The invention also relates to methods for determining whether a test compound may inhibit multidrug resistance.

Abstract: Use of the blockade of costimulation and hematopoietic stem cells in allograft transplantation.

Abstract: Disclosed herein are methods for suppressing allograft rejection in mammals comprising administering to a mammal about to undergo or having undergone allograft surgery an agent selected from the group consisting of splenic tissue from an allograft donor, splenic extracts, cultured lymphocytes from an allograft donor, extracts of said cultured lymphocytes, MHC antigens, transplantation rejection suppressive fragments and analogs of MHC antigens in an oral or aerosol form. Also disclosed herein are pharmaceutical formulations and dosage forms for use in said methods.

Abstract: Described are methods for: (a) suppressing the ability of T-cells from a mammal to proliferate in response to stimulation by nonself mammalian tissue; and (b) suppressing immune response which leads to allograft rejection in a mammal receiving an allograft from a donor mammal. The methods involve orally administering to the mammal to be thus treated a composition comprising at least one of: (i) a major histocompatibility complex Class II antigen from a second nonself mammal or from tissue of a mammal syngeneic to said nonself mammal; (ii) at least one synthetic peptide corresponding to a T-cell suppressive fragment of said Class II antigen, said composition being administered in an amount effective to suppress said proliferation. The foregoing compositions are also described.
