摘要:
This invention provides a means for enabling high-level secretory production of proteins, in particular proteins having complicated structures such as antibodies, in host cells such as yeast cells. The invention also provides transformed yeast cells having the activated HAC1 gene and the RRBP1 gene and a method for enabling high-level secretory production of foreign proteins using such transformed host cells by inhibiting O-sugar chain formation indigenous to host cells such as yeast cells.
摘要:
It is intended to provide a process for producing a glycoprotein having a mammalian type sugar chain characterized by comprising transferring and expressing α-1,2-mannosidase in a sugar chain biosynthesis pathway gene mutant of a methylotroph yeast under the control by a potent promoter, culturing in a medium the methylotroph yeast cells having a foreign gene transferred thereinto, and then harvesting the glycoprotein having the mammalian type sugar chain from the culture medium. Using a newly bred methylotroph yeast carrying a sugar chain mutation, a neutral sugar chain identical with a high mannose type sugar chain produced by mammalian cells such as human cells or a glycoprotein having such a neutral sugar chain can be produced in a large amount at a high purity. By transferring a gene in a mammalian type sugar chain biosynthesis pathway into the above-described mutant, a mammalian type sugar chain such as a hybrid sugar chain or a complex sugar chain or a protein having a mammalian type sugar chain can be efficiently produced.
摘要:
This invention provides an agonist antibody to a human thrombopoietin receptor (alias: human c-Mpl). More particularly, this invention provides an agonist antibody to a human thrombopoietin receptor, wherein the agonist antibody comprises: antibody constant regions comprising (1) amino acid sequences in a heavy chain constant region and a light chain constant region of a human antibody, (2) an amino acid sequence of a heavy chain constant region with a domain substituted between human antibody subclasses, and an amino acid sequence of a light chain constant region of a human antibody, or (3) amino acid sequences comprising a deletion(s), substitution(s), addition(s), or insertion(s) of one or several amino acid residues in the amino acid sequences of (1) or (2) above ; and antibody variable regions capable of binding to and activating a human thrombopoietin receptor; and wherein the agonist antibody has the properties: (a) that the antibody induces colony formation at a concentration of 10,000 ng/ml or lower as determined by the CFU-MK colony formation assay using human umbilical-cord-blood-derived CD34+ cells; and (b) that the antibody has a maximal activity at least 50% higher than that of PEG-rHuMGDF and an 50% effective concentration (EC50) of 100 nM or less in the cell proliferation assay using UT7/TPO cell. Also provided is a pharmaceutical composition for treating thrombocytopenia comprising said antibody.
摘要:
This invention provides novel CD40L polypeptides and nucleic acids, as well as antigen presenting cells and vaccines comprising such CD40L polypeptides and/or nucleic acids, and related methods for preparing the antigen presenting cells and vaccines. The antigen presenting cells and vaccines are useful for enhancing an immune response. The invention provides a method for preparing mature dendritic cells (DCs), comprising the sequential steps of: (a) signaling isolated immature dendritic cells (iDCs) with a first signal comprising an interferon gamma receptor (IFN-?R) agonist and/or a tumor necrosis factor alpha receptor (TNF-?R) agonist to produce signaled dendritic cells; and (b) signaling said signaled dendritic cells with a second transient signal comprising an effective amount of a CD40 agonist to produce CCR7+ mature dendritic cells. Also provided by this invention are enriched populations of dendritic cells prepared by the methods of the invention. Such dendritic cells have enhanced immunostimulatory properties and increased IL-12 secretion and/or decreased IL-10 secretion. CD40 signaling can be initiated by one or more of polypeptide translated from an exogenous polynucleotide encoding CD40L (e.g., mRNA or DNA), an agonistic antibody to CD40 receptor or by CD40 ligand polypeptide. The enriched populations can be further modified by the administration of an immunogen to the DC. The DC will take up and process the immunogen on its cell surface.
摘要:
Medicament devices include a sealed medicament dose container comprising a cell based medicament that is stored at a temperature less than about -40 degrees Celsius, then thawed into a liquid prior to administration and a medicament dose cartridge configured and sized to snugly hold the dose container therein during extraction of the liquid medicament. Related dose containers, retainers and extraction/dispensing systems are also described.
