    • Disclosed is a class of compounds referred to herein as effector compounds. Effector compounds are useful in connection with the modulation of an immune response. Modulation refers to the ability of the effector compounds of the present invention to either enhance (antigen supercharging) or inhibit (immunosuppressant activities) antigen presentation, depending upon the nature of the particular effector compound and the therapeutic context. Effector compounds include peptides, modified peptides and peptidomimetics. Also disclosed are methods for modulating presentation of an MHC class II restricted antigenic peptide to a T cell. Also disclosed are effector compounds demonstrated to act specifically on a human MHC class II allele. Also disclosed is a second class of compounds, referred to herein as immunomodulatory organic compounds. Such compounds are identified by a method which includes the following steps: providing a first complex comprising an MHC class II molecule to which an antigenic peptide has been bound; contacting the first complex with mammalian Ii key peptide LRMKLPKPPKPVSKMR (SEQ ID NO:1) (or modifications thereof including peptidomimetics), thereby forming a second complex; and screening organic molecules for compounds which bind to the second complex but not to the first complex, and which exhibit immunomodulatory activity. Compounds identified in this manner can be used to modulate an immune response in a mammal.

    • Methods and products for stimulating hematopoiesis, preventing low levels of hematopoietic cells and producing increased numbers of hematopoietic and mature blood cells are provided. The methods and products can be used both in vivo and in vitro. The methods involve administering an agent of Formula I: wherein m is an integer between 0 and 10, inclusive; A and A1 are L-amino acid residues such that the A in each repeating bracketed unit can be the same or a different amino acid residue; the C bonded to B is in the L-configuration; the bonds between A and N, A1 and C, and between A1 and N are peptide bonds; and each X1 and X2 is, independently, a hydroxyl group or a group capable of being hydrolyzed to a hydroxyl group in aqueous solution at physiological pH. A particularly preferred agent that is useful in practicing the invention is a ValBoroPro.
    • 提供了刺激造血作用的方法和产品,防止造血细胞水平降低并造成造血和成熟血细胞数量增加。 方法和产品可以在体内和体外使用。 所述方法包括施用式I的试剂:其中m为0至10的整数,包括端值; A和A1是L-氨基酸残基,使得每个重复括号中的A可以相同或不同的氨基酸残基; 与B结合的C处于L构型; A和N,A1和C之间以及A1和N之间的键是肽键; 并且每个X1和X2独立地是在生理pH下能够在水溶液中水解成羟基的羟基或基团。 可用于实施本发明的特别优选的试剂是ValBoroPro。
