Peptidyl-prolyl cis/trans isomerases (PPIases) are an enzyme family which catalyse the isomerisation of proline peptide bonds to promote folding and re-folding peptides proteins. Three subfamilies have been identified: cyclophilins, FK506-binding proteins parvulins. Individual PPIases overexpressed in a number cancers [62], members targetted for immunosuppressant effects.
Compelling evidences indicate a key role for regulatory T cells (T(reg)) on the host response to cancer. The Wilms' tumor antigen (WT1) is overexpressed in several human leukemias and thus considered as promising target for development of leukemia vaccine. However, recent studies indicated that the generation of effective WT1-specific cytotoxic T cells can be largely affected by the presence of...
Proteolysis of proteins and peptides is involved in the infection cells by enveloped viruses also invasion spread cancer cells. Shutting down broad-specificity proteases, however, problematic because normal functions these proteases will be affected. Herein, nanoparticle receptors were prepared from molecular imprinting for complex biological peptides. Their strong selective binding enabled the...
One of the critical steps in the progression to cervical cancer appears to be the establishment of persistent human papillomavirus (HPV) infection. We have demonstrated that the lack of cytotoxic T-lymphocyte response to HPV type 16 (HPV 16) E6 protein was associated with persistence and that the potential presence of dominant CD8 T-cell epitopes was most frequently found (n = 4 of 23) in the E...
Targets of curative donor-derived graft-versus-myeloma (GVM) responses after allogeneic hematopoietic stem cell transplantation (HSCT) remain poorly defined, partly because immunity against minor histocompatibility Ags (mHAgs) complicates the elucidation of multiple myeloma (MM)-specific targets. We hypothesized that syngeneic HSCT would facilitate the identification of GVM-associated Ags becau...
Using the allo-restricted T-cell approach to circumvent tolerance, we have previously identified a cytotoxic T-lymphocyte (CTL) epitope in the transcription factor Wilms tumor antigen 1 (WT1) presented by HLA-A0201 (A2) class I molecules. Here we describe an additional A2-presented epitope and show that CTLs against both epitopes kill WT1-expressing leukemia cell lines. Colony-forming assays de...
Accelerated molecular dynamics is used to explore the binding of Zn N-terminal fragment amyloid-β, and test performance AMBER-style forcefields. • AMBER forcefield reproduces NMR structure Zn(II) bound Aβ. Implicit solvent performs at least as well explicit in this regard. MD shows subtle difference for different modes. Free energy surface restriction size flexibility due Zn-binding. We report ...
Recently, new molecular breeding and genetic engineering approaches have emerged to overcome the limitations of conventional breeding methods in generating disease-resistance transgenic plants. The use of antimicrobial peptides (AMPs) to produce transgenic plants resistant to a wide range of plant pathogens has achieved great success. Among huge number of AMPs, Dermaseptin B1 (DrsB1), an antimi...
The Par complex is a conserved cell polarity regulator. Bazooka/Par-3 is scaffold for the complex and contains three PDZ domains in tandem. PDZ domains can act singly or synergistically to bind the C-termini of interacting proteins. Sequence comparisons among Drosophila Baz and its human and C. elegans Par-3 counterparts indicate a divergence of the peptide binding pocket of PDZ1 and greater co...
