Abstract
Antigen non-specific human glycosylation inhibiting factor derivatives having the inmunosuppressive activity in which a mutation was introduced for replacement, deletion and/or insertion of a part of the amino acid sequence of SEQ ID NO:21, and/or which has received a chemical modification of one or more amino acid residue(s) in the amino acid sequence of SEQ ID NO:21, wherein the mutation and the chemical modification attenuate the strength of an intermolecular association in the region, which participates in trimerization, of an antigen non-specific human glycosylation inhibiting factor having the amino acid sequence of SEQ ID NO:21; DNAs containing a base sequence encoding the amino acid sequence of the antigen non-specific human glycosylation inhibiting factor derivative; recombinant vectors containing the DNAs; prokaryotic or eukaryotic cells transformed with the DNAs; methods of producing the antigen non-specific human glycosylation inhibiting factor derivatives; pharmaceutical compositions comprising the antigen non-specific human glycosylation inhibiting factor derivative and a pharmaceutically acceptable carrier; and methods of suppressing a human immune response to an antigen are provided.
