Interleukin-10 (IL-10) conjugated via a linker to one or more polyethylene glycol (PEG) molecules at a single amino acid residue of the IL-10, and a method for preparing the same, are provided. The method produces a stable mono-pegylated IL-10, which retains IL-10 activity, where pegylation is selective for the N-terminus on one subunit of IL-10 with little or no formation of monomeric IL-10. The method also provides a substantially homogenous population of mono-PEG-IL-10.

This invention is related to the use of at least one oligonucleotide with a length of from about 8 to about 30 nucleotide building blocks for manufacturing a pharmaceutical preparation for the prophylaxis and/or the treatment of diseases, that are modulated by TGF-beta2, TGF-beta1, TGF-beta3, VEGF, interleukin-10, c-jun, c-fos, and/or prostaglandin E2 in a mammal, wherein said oligonucleotide hybridizes with a messenger RNA of a TGF-beta2, TGF-beta1, TGF-beta3, VEGF, interleukin-10, c-jun, c-fos and/or prostaglandin E2 gene and wherein said preparation comprises said oligonucleotide in a concentration of about 1 microM to about 25 microM.

The invention discloses a fusion protein and a coding gene and application thereof. The fusion protein provided by the invention is formed by connecting any one of the following proteins at the carboxyl terminal of human interleukin-10 protein: 1) human IgGFc-gamma 1 or mutant protein thereof, and 2) human IgGFc-gamma 2 or mutant protein thereof, wherein the amino acid sequence of the human interleukin-10 protein is an amino acid sequence from 1st to 160th site of the amino terminal of the sequence 1 in a sequence table. Proved by experiments, the IL-10-IgG/Fc fusion protein of interleukin-10activity is produced by using a pichia pastoris fermentation expression system, and a foundation for clinically researching the treatment effect of the IL-10-IgG/Fc fusion protein in the next step.

A method for treating renal disease includes administering to a patient suffering from renal disease an effective amount of antibody or of a functional equivalent thereof to at least two of urea, creatinine, tumor necrosis factor alpha, interferon gamma, interleukin 6 and interleukin 1 beta. Soluble cytokine receptors also can be employed. Antibody, functional equivalent thereof or soluble cytokine receptor to interleukin 10 or interleukin 13 also can be administered. The method can be used as a supplement to or as partial or complete replacement for dialysis. A pharmaceutical composition includes antibody or functional equivalent thereof to urea, creatinine, or both; antibody, functional equivalent or soluble cytokine receptor to tumor necrosis factor alpha, interferon gamma, interleukin 6, interleukin 1 beta or any combination thereof; and, optionally, antibody, functional equivalent or soluble cytokine receptor to interleukin 10, interleukin 13 or both. The composition can be included in a kit.

The present disclosure is directed to interleukin-10 (IL-10) peptides and isolated antibodies that specifically bind to the IL-10 peptides. The IL-10 peptides and the isolated antibodies may be administered alone or as an animal feed additive to treat gastrointestinal protozoan infection in animals.

It has been discovered that reducing, inhibiting or preventing the expression of immunosuppressive cytokines or tolergenic agents in antigen presenting cells improves the ability of the antigen presenting cell to promote an immune response. One embodiment provides a genetically engineered antigen presenting cell that has reduced or no expression of IL-10. Preferred antigen presenting cells are dendritic cells. Expression of IL-10 can be inhibited or blocked by genetically engineering the antigen presenting cell to express inhibitory nucleic acids that inhibit or prevent the expression mRNA encoding immunosuppressive cytokines. Inhibitory nucleic acids include siRNA, antisense RNA, antisense DNA, microRNA, and enzymatic nucleic acids that target mRNA encoding immunosuppressive cytokines. Immunosuppressive cytokines include, but are not limited to IL-10, TGF-β, IL-27, IL-35, or combinations thereof. Tolerogenic agents include but are not limited to indoleamine 2,3-dioxygenase.

The present invention generally relates to fusion proteins of antibodies and interleukin-10 (IL-0). More particularly, the invention concerns fusion proteins of antibodies and mutant IL-10 that exhibit improved properties for use as therapeutic agents, e.g. in the treatment of inflammatory diseases. In addition, the present invention relates to polynucleotides encoding such fusion proteins, and vectors and host cells comprising such polynucleotides. The invention further relates to methods for producing the fusion proteins of the invention, and to methods of using them in the treatment of disease.

The invention provides application of nitidine chloride to the preparation of a medicament for resisting autoimmunity disease and graft versus host disease. An experiment shows that the nitidine chloride can inhibit the proliferation of human dendritic cells in vitro, inhibit the human dendritic cells from promoting the proliferation reaction of allogeneic T cells and strengthen the capacity of secreting interleukin 10 of the human dendritic cells. Meanwhile, in an experimental autoimmunity disease cerebrospinal meningitis model, when used in vivo, the nitidine chloride can reduce the average clinical score of a mouse and inhibit the spinal marrow infiltration degree of monocytes and can obviously improve the secretion level of the interleukin 10 in the blood serum of the mouse. In a heart transplantation experiment, when used in vivo, the nitidine chloride can prolong the survival time of the transplanted heart. In a delayed type hypersensitivity reaction model, when used in vivo, the nitidine chloride can reduce the ear swelling degree of the mouse. Both in-vivo and in-vitro results show that the nitidine chloride has a certain effect of resisting the autoimmunity disease and the graft versus host disease. The medicament is a preparation which consists of the nitidine chloride serving as an active ingredient and a pharmaceutical carrier. The medicament can be prepared into an oral preparation, an injection, a suppository or an external preparation and the like.
