The present invention provides an antibody composition comprising an antibody molecule which specifically binds to human CC chemokine receptor 4 (CCR4) and has complex type N-glycoside-linked sugar chains in the Fc region, wherein the complex type N-glycoside-linked sugar chains have a structure in which fucose is not bound to N-acetylglucosamine in the reducing end in the sugar chains; a transformant which produces the antibody composition; a process for producing the antibody composition; and a pharmaceutical composition comprising the antibody composition.

A medicament having a higher therapeutic effect than that provided by administration of a recombinant antibody against human CC chemokine receptor 4 or an antibody fragment thereof or an agent alone is provided.

The invention discloses a human immunodeficiency virus (HIV) affinity adsorption column, comprising a column body and at least one activated affinity microsphere located in the column body, wherein the activated affinity microsphere is connected with a human immunodeficiency virus affinity protein, and the affinity protein can be bound with human immunodeficiency virus. The affinity protein comprises a main receptor CD4 molecule, a gp120 antibody, an auxiliary receptor CXC chemokine receptor 4 (CXCR-4) and a CC chemokine receptor 5 (CCR-5). The affinity microsphere may be a glass microsphere with the size of 1mm, a chitosan crosslinking microsphere with the diameter more than 500 microns, or a gluosan microsphere. The human immunodeficiency virus affinity adsorption column disclosed by the invention is applicable for eliminating the human immunodeficiency virus in the blood of HIV patients, and relieving and treating the immunodeficiency syndrome of HIV patients; and compared with the traditional treatment methods, the immunoadsorption column has high safety, good specificity, small toxic or side effects and good operation simplicity.

The present invention relates to therapeutic compositions and methods for treating and preventing infection by an immunodeficiency virus, particularly HIV infection, using chemokine proteins, nucleic acids and/or derivatives or analogues thereof.

It is intended to provide preventives/remedies for graft-versus-host disease and/or rejection in organ or bone marrow transplantation, rheumatoid arthritis, autoimmune diseases, allergic diseases, ischemic cerebral cell injury, myocardial infarction, chronic nephritis and arteriosclerosis. The above object can be achieved by preventives/remedies for graft-versus-host disease and/or rejection in organ or bone marrow transplantation, rheumatoid arthritis, autoimmune diseases, allergic diseases, ischemic cerebral cell injury, myocardial infarction, chronic nephritis and arteriosclerosis characterized by containing a specific compound having a CCR (CC chemokine receptor) antagonism.

The present invention relates to an antibody or functional fragment thereof which binds to a mammalian (e.g., human) CC-chemokine receptor 1 (CCR1) or a portion of the receptor and blocks binding of a ligand to the receptor. The invention further relates to a method of inhibiting the interaction of a cell bearing mammalian CCR1 with a ligand thereof, and to use of the antibodies and fragments in research, therapeutic, prophylactic and diagnostic methods.

The susceptibility of human macrophages to human immunodeficiency virus (HIV) infection depends on cell surface expression of the human CD4 molecule and CC cytokine receptor 5. CCR5 is a member of the 7-transmembrane segment superfamily of G-protein-coupled cell surface molecules. CCR5 plays an essential role in the membrane fusion step of infection by some HIV isolates. The establishment of stable, nonhuman cell lines and transgenic mammals having cells that coexpress human CD4 and CCR5 provides valuable tools for the continuing research of HIV infection. In addition, antibodies which bind to CCR5, CCR5 variants, and CCR5-binding agents, capable of blocking membrane fusion between HIV and target cells represent potential anti-HIV therapeutics for macrophage-tropic strains of HIV.

Novel CC chemokines from human, reagents related thereto including purified proteins, specific antibodies and nucleic acids encoding these chemokines are provided. Also provided are methods of making and using said reagents and diagnostic kits.

CC-Chemokine mutants having reduced Glycosaminoglycans (GAG)-binding properties are effective against liver fibrotic inflammatory and/or autoimmune diseases. Particularly preferred are the mutants of CCL5/RANTES having reduced GAG-binding properties.

The present disclosure provides antibodies which bind to an epitope in the extracellular domain of human CC chemokine receptor 4 (CCR4) and which are capable of inhibiting the binding of macrophage-derived chemokine (MDC) and/or thymus and activation regulated chemokine (TARC) to CCR4. Also provided are inter alia immunoconjugates and compositions comprising such antibodies and methods and uses involving such antibodies, particularly in the medical and diagnostic fields.

It is intended to provide a novel drug which exhibits an excellent effect of preventing HIV infection in transfusing blood and using a blood preparation. This object can be achieved by a preventive for HIV infection in transfusing blood and using a blood prepartion characterized by containing a compound having an antagonism to a CC chemokine receptor (preferably antagonism to CCR5 and/or CCR2).

Mutants of specific CC-chemokines containing a non-conservative substitution in a conserved consensus sequence act as CC-chemokine antagonists, and can be effectively used in the treatment of autoimmune and inflammatory diseases, cancers, and viral or bacterial infections. Particularly preferred are the RANTES/CCL5 mutants having the amino acid sequence of SEQ ID NO: 1, 2, 3, or 4.

The invention belongs to the technical field of genetic engineering and specifically relates to an inference sequence capable of inhibiting diabetes mellitus type I specificity-related gene expression as well as a recombinant vector thereof and an application of the recombinant vector in preparing a medicine for treating diabetes mellitus type I. The recombinant vector constructed by the inference sequence is used for transfecting mouse T lymphocytes, so that secretion of Th1/Th2 cell factors can be affected, and therefore, the recombinant vector plays an important role in insulitis at a prediabetic state, and blocks a process of the diabetes mellitus type I. The invention provides a novel means for treating the diabetes mellitus type I.
