The present invention is directed to peptides of the formulas (i) Xaa-Yaa-Arg, wherein either Xaa is any amino acid residue and Yaa is Glu or Xaa is absent and Yaa is any amino acid residue with the exception of Pro; (ii) Arg-Yaa-Xaa, wherein either Xaa is any amino acid residue and Yaa is Glu or Xaa is absent and Yaa is any amino acid residue with the exception of Asn; (iii) Xaa-Arg-Yaa, wherein Xaa is any amino acid residue and Yaa is Glu; and (iv) Yaa-Arg-Xaa, wherein Xaa is any amino acid residue and Yaa is Glu, and to derivatives thereof, which exert an inhibitory effect on macrophage migration and/or macrophage phagocytic activity. In addition, the peptides and derivatives thereof exert an inhibitory effect on the ability of macrophages and T cells to adhere to extracellular matrix and/or fibronectin. The peptides and derivatives thereof exert an inhibitory effect on a humoral and/or cellular immune response. The invention is also directed to methods for use of the peptides and derivatives thereof and compositions containing them for the inhibition of inflammation, including but not limited to, inflammation at a joint, in the central nervous system generally, at specific lesions in the central nervous system, and other immune privileged sites.
