Quantitation of antigen-reactive T cells in peripheral blood by IFNgamma-ELISPOT assay and chromium-release assay: a four-centre comparative trial

2000

The ELISPOT assay is increasingly being used for the monitoring of the induction of antigen-reactive T cells in cancer vaccination trials. In order to evaluate the reliability of T cell frequency analysis with the ELISPOT assay, a comparative study was performed in four European laboratories. Six samples from healthy subjects were analyzed for the frequency of influenza-reactive CD8+ T cells in peripheral blood mononuclear cells (PBMC) by IFNgamma-ELISPOT assay. In addition, one laboratory determined cytotoxic T cell precursor (CTL) frequencies in these samples by limiting dilution chromium-release assay (LDA), and three laboratories performed a variant of the LDA, the multiple microculture…

Theoretical studies of HIV-1 reverse transcriptase inhibition

2012

Computational methods for accurately calculating the binding affinity of a ligand for a protein play a pivotal role in rational drug design. We herein present a theoretical study of the binding of five different ligands to one of the proteins responsible for the human immunodeficiency virus type 1 (HIV-1) cycle replication; the HIV-1 reverse transcriptase (RT). Two types of approaches are used based on molecular dynamics (MD) simulations within hybrid QM/MM potentials: the alchemical free energy perturbation method, FEP, and the pathway method, in which the ligand is physically pulled away from the binding site, thus rendering a potential of mean force (PMF) for the binding process. Our com…
