Quantitative analysis of the antiviral activity of CD8(+) T cells from human immunodeficiency virus-positive asymptomatic patients with different rates of CD4(+) T-cell decrease.

abstract：:The hepadnavirus P gene contains amino acid sequences which share homology with all known RNases H. In this study, we made four mutants in which single amino acids of the duck hepatitis B virus (DHBV) RNase H region were altered. In two of them, amino acids at locations comprising the putative catalytic site were chan...

abstract：:Herpes simplex virus (HSV) has often been suggested for development as a vector, particularly for the nervous system. Considerable evidence has shown that for use of HSV as a vector, immediate-early (IE) gene expression must be minimized or abolished, otherwise such vectors are likely to be highly cytotoxic. Mutations...
