Cytotoxic T cells generally recognize short 8-mer to 11-mer peptides in association with major histocompatibility complex (MHC) class I molecules on the surface of the antigen presenting cells (APCs). Usually, these peptides are produced in the cytosol of the APCs by proteolytic degradation of cytosolic proteins. The peptides are subsequently transported first to the endoplasmatic reticulum (ER...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
Measles virus (MV) hemagglutinin (MV-H) and fusion (MV-F) proteins induce plaque reduction neutralizing (PRN) antibodies and cell-mediated immune responses that protect against clinical measles. DNA vaccines that encode MV-H and MV-F are being investigated as a new generation of measles vaccine to protect infants too young to receive currently licensed attenuated measles vaccines. However, it i...
Virus-specific CD4(+) T cell responses have been shown to play a critical role in controlling HIV-1 replication. Candidate HIV-1 vaccines should therefore elicit potent CD4(+) as well as CD8(+) T cell responses. In this report we investigate the ability of plasmid GM-CSF to augment CD4(+) T cell responses elicited by an HIV-1 gp120 DNA vaccine in mice. Coadministration of a plasmid expressing G...
The simplicity and sensitivity of the bimolecular fluorescence complementation (BiFC) assay make it a powerful tool to investigate protein-protein interactions (PPIs) in living cells. However, non-specific association of the fluorescent protein fragments in a BiFC system can complicate evaluation of PPIs. Here, we introduced a bicistronic expression vector, pBudCE4.1, into an mLumin-based BiFC ...
We used a simple and efficient method to construct the bicistronic eukaryotic expression vector pIRES2-VEGF165-NT-3. The neurotrophin-3 (NT-3) gene was obtained from the genomic DNA of human peripheral blood mononuclear cells by polymerase chain reaction. The NT-3 cDNA fragment was cloned into the pIRES2-VEGF165-EGFP vector in place of enhanced green fluorescent protein (EGFP) to create the pla...
Recombinant retroviral vectors are still the most common gene delivery vehicles for gene therapy purposes, especially for construction of genetically modified tumor vaccines (GMTV). However, these vehicles are characterized by relatively low titre and in the case of many tumor cell lines, low transduction efficiency. We constructed bicistronic retroviral vector pseudotypes of amphotropic murine...
