A method for treating a subject afflicted with an autoimmune disease with a pharmaceutical composition comprising glatiramer acetate and a pharmaceutically acceptable carrier, comprising the steps of administering a therapeutic amount of the pharmaceutical composition to the subject, determining whether the subject is a glatiramer acetate responder or a glatiramer acetate hypo- / non-responder by measuring the value of a biomarker selected from the group consisting of IL-10 concentration, IL-17 concentration, IL-18 concentration, TNF-α concentration, BDNF concentration, caspase-1 concentration, IL-10 / IL-18 ratio and IL-10 / IL-17 ratio in the blood of the subject, and comparing the measured value to a reference value for the biomarker to identify the subject as a glatiramer acetate responder or a glatiramer acetate hypo- / non-responder, and continuing the administration if the subject is identified as a glatiramer acetate responder, or modifying treatment of the subject if the subject is identified as a glatiramer acetate hypo- / non-responder.

To provide a microorganism and an ingredient thereof that contribute to prevention and treatment of immune diseases including allergy, autoimmune diseases and inflammatory bowel diseases (e.g., large-intestinal ulcer), a method of effectively selecting the microorganism, and a method of efficiently inducing immunoregulatory cells that play an important role on maintaining immunological homeostasis using the microorganism or the ingredient thereof. The present invention provides a Lactococcus and an ingredient thereof which induce production of IL-10 from mammalian dendritic or spleen cells, a method of obtaining the microorganism or the ingredient thereof by co-culturing a microorganism such as Lactococcus strains with mammalian dendritic or spleen cells to select a microbial cell having a high IL-10 production ability, a method of selecting the microorganism or the ingredient thereof by co-culturing an intestinal epithelial cell with a microorganism such as the lactic acid bacteria and selecting the cells on the basis of a caspase-1 activity and the ability of inducing the production of IL-18, and a food product or material and an animal feeding stuff or medical and pharmaceutical products which contain the lactic acid bacteria as an effective ingredient.

The invention discloses a caspase-1 inhibitor targeting liver. The caspase-1 inhibitor is formed by connection of human hepatitis B virus Pre-S1 peptide and caspase-1 inhibitor through a flexible connector, wherein the Pre-S1 peptide consists of amino acids from first to fiftieth of the Pre-S1 protein; and the caspase-1 inhibitor is formed by connection of trimolecular polymer of YVAD tetrapeptide and trimolecular polymer of VAD tripeptide. According to the inhibitor, the caspase-1 inhibitor is specifically targeted to a liver cell by utilizing the carrier Pre-S1 peptide which specifically targets liver, so that intrahepatic persistent chronic inflammation caused by endogenous danger signals released by injured liver cells can be blocked by terminating caspase-1 activation in the liver cell, sequential spinal cord injury of the liver cell can be blocked, body adverse response which is possibly caused by spread inhibition of caspase-1 can be reduced, and the liver cell can be specifically and effectively protected. The caspase-1 inhibitor can be used for preparing a medicament for treating intrahepatic chronic inflammation caused by endogenous danger signals released by injured liver cells.

The invention discloses application of an NALP3-ASC inflammation complex and an activator inhibitor thereof in terms of preparation of medicines for treating prion diseases. Experiments show that prion infects microgliacyte, NALP3-ASC inflammation complex enhanced caspase-1 and IL-1beta activation are formed. The inflammation complex NALP3 inhibitor can suppress NALP3 and ASC expression, and then suppresses activation and release of the caspase-1 and IL-1beta. The invention provides the application of the NALP3-ASC inflammation complex inhibitor for screening medicines for treating the prion diseases, by means of cell co-stimulation for a sample to be detected and the prion, total RNA (ribonucleic acid) of treated cells is extracted, NALP3 and ASC are detected by a qPCR (quantitative polymerase chain reaction) method, expression suppression conditions of the sample to mRNA (messenger ribonucleic acid) of the NALP3 and the ASC are judged according to PCR (polymerase chain reaction) amplification results, accordingly medicines for resisting Prion diseases are screened out, and effects of preventing, treating or controlling the prion diseases are realized.
