Abstract:
PURPOSE: Proliferation of bone marrow-derived immune regulatory cells and immune regulatory B lymphocytes in vivo and in vitro is provided to show a method for screening a therapeutic agent for treating GPCR19-related diseases or a method for analyzing efficacy of a GPCR19 agonist, thereby producing an anti-inflammatory pharmaceutical composition. CONSTITUTION: An immune regulatory B cell is transformed or amplified by treatment with toll-like receptor (TLR) signal transduction inducing factor and a GPCR19 agonist or with myeloid-derived suppressor cells (MDSC). The immune regulatory B cells show CD23^hi phenotype on the surface and have an anti-inflammatory activity. The immune regulatory B cells express CD21 and CD23. The TLR signal transduction inducing factor is a factor derived from bacteria, fungi, virus, allergen, or cancer cells, or a self-derived factor. The GPCR19 agonist is a compound of chemical formula 1 or a salt or a hydrate thereof.
Abstract:
PURPOSE: A method for screening a therapeutic agent for treating GPCR19(G-protein coupled receptor 19)-related diseases or a method for analyzing efficiency of a GPCR19 agonist is provided to obtain an anti-inflammatory pharmaceutical composition. CONSTITUTION: A method for screening a therapeutic agent for treating GPCR19-related diseases comprises: a step of administering a physiological activity control material to mammals exclusive of humans; a step of administering a GPCR19 agonist test material to the mammals; and a step of analyzing generation of regulatory B cells in the mammals. The test material is determined as a therapeutic agent for treating GPCR19-related diseases when cell production is increased over a control group.
Abstract:
PURPOSE: A fusion antigen and a method for manufacturing a mature dendritic cell vaccine for immunotherapy using the same are provided to improve efficiency. CONSTITUTION: A fusion antigen used in manufacturing dendritic cell vaccine for immunotherapy contains PTD-MUC1 fusion protein containing MUC1(mucin antigen 1) fused to protein transduction domain(PTD) or PTD-Ag85A fusion protein. The fusion antigen is PTD-MUC1-Ag85A or PTD-Ag85A-MUC1. A method for manufacturing the dendritic cell vaccine comprises: a step of preparing immature dendritic cells; and a step of culturing the cells with the fusion antigen for maturing the cells. A pharmaceutical composition for anticancer immunotherapy contains pharmaceutically effective amount of the dendritic cell vaccine and pharmaceutically acceptable carrier.
