Abstract: A method for measuring the activity of cytotoxic T lymphocytes (CTLs) includes preparing peripheral blood mononuclear cells (PBMCs) from blood of an animal; preparing mature dendritic cells by isolating monocytes from the PBMCs, differentiating the monocytes into dendritic cells for presenting an antigen molecule and pulsing dendritic cells with the antigen molecule to obtain the mature dendritic cells; preparing the CTLs as an effector cell by stimulating the PBMCs with the mature dendritic cells to activate and amplify the CTLs; preparing target cells by pulsing the PBMCs, monocytes or B cells with a cytoplasmic transduction peptide (CTP)-antigen complex generated by linking the antigen molecule of step (b) to the CTP; treating the target cells with the effector cells; and analyzing the lysis of the target cells. In addition, a kit for measuring the activity of cytotoxic T lymphocytes is provided.

Abstract: The present invention relates to a novel recombinant Sabin type 1 poliovirus vector for the immunogenicity of neutralizing antibody against polioviral infection, which comprises: (a) a genomic nucleotide sequence of a parent Sabin type 1 poliovirus; (b) a nucleotide sequence encoding an additional polioviral cleavage site; and (c) a nucleotide sequence of a conformational epitope encoding a VP1 neutralizing epitope of poliovirus type 2 or 3 and linked to the nucleotide sequence of (b).

Abstract: The present invention relates to a cytoplasmic transduction peptide (CTP) showing transduction potential, as well as cytoplasmic remaining potential and various uses thereof. The CTP of this invention exhibits a transduction potential identical or higher than the conventional protein transduction, PTD, and a strong tendency to remain in the cytoplasm, so that it is very useful in inducing cytotoxic T lymphocytes (CTL) and a drug delivery system (DDS) targeting cytoplasm.

Abstract: The present invention relates to dentritic cell-specific polynucleotides and microarrays, particularly to novel polynucleotides highly expressed in dendritic cells, certain dendritic cell subsets and matured dendritic cells and microarrays comprising thereof. With a marrcoarray of this invention, dendritic cells, certain dendritic cells subsets and matured dendritic cells can be detected rapidly and accurately.

Abstract: The present invention relates to (a) methods for improving a genetic stability of an insert nucleotide sequence in a recombinant single-stranded RNA virus vector, which comprises performing a mutagenesis of the foreign insert nucleotide sequence to provide even distribution of G/C content throughout the overall foreign insert nucleotide sequence and/or to increase G/C content of the foreign insert without substantially causing amino acids substitutions (b) a recombinant single-stranded RNA virus comprising an insert nucleotide sequence with improved genetic stability and (c) a recombinant poliovirus comprising an insert nucleotide sequence with improved genetic stability.

Abstract: A replication-competent recombinant Sabin type 1 poliovirus vector containing a sequence coding for multiple cloning site and 3C-protease cleavage site is provided. This vector makes it easy to introduce various vaccine genes from infectious viruses to the Sabin 1 poliovirus, and facilitates to produce chimeric Sabin 1 polioviruses that are expected to be powerful oral mucosal vaccines against several infectious viral diseases.

Abstract: The present invention relates to a pharmaceutical composition for immunotherapy of autoimmune disease, which comprises (a) a therapeutically effective dose of maturated dendritic cells and (b) a pharmaceutically acceptable carrier and a method for immunotherapy of autoimmune disease.
