Although primary antiviral CD8+ cytotoxic T lymphocytes (CTL) can be induced in mice depleted of CD4+ cells, the role generation and maintenance memory CTL is uncertain. This question, consequences upon vaccine-mediated protection, were investigated transgenic CD4 knockout (CD4ko) mice, which lack lymphocytes. Infection immunocompetent C57BL/6 with lymphocytic choriomeningitis virus (LCMV), or recombinant vaccinia viruses bearing appropriate LCMV sequences, induces long-lasting protective...

DNA vaccination has been evaluated with the lymphocytic choriomeningitis virus (LCMV) model system. Plasmid encoding LCMV nucleoprotein, when injected intramuscularly, induces both antiviral antibodies and cytotoxic T lymphocytes. Injection of nucleoprotein or viral glycoprotein confers protection against normally lethal challenge in a major histocompatibility complex-dependent manner. The conferred is incomplete, but it most probably mediated by induced

ABSTRACT Our previous studies have shown that isolated cytotoxic T lymphocyte (CTL), B-cell, and T-helper epitopes, for which we coined the term minigenes, can be effective vaccines; when expressed from recombinant vaccinia viruses, these short immunogenic sequences confer protection against a variety of viruses bacteria. In addition, previously demonstrated utility DNA immunization using plasmids encoding full-length viral proteins. Here combine two approaches evaluate effectiveness...

Mercaptoundecahydrododecaborate (BSH)-encapsulating 10% distearoyl boron lipid (DSBL) liposomes were developed as a delivery vehicle for neutron capture therapy. The current approach is unique because the liposome shell itself possesses cytocidal potential in addition to its encapsulated agents. BSH-encapsulating DSBL have high content (B/P ratio: 2.6) that enables us prepare solution with 5000 ppm concentration. displayed excellent efficacy tumor: concentrations reached 174, 93, and 32 at...

Abstract Synthesis of a novel conjugate anticancer drug adriamycin, poly(ethylene glycol)‐ block ‐poly(aspartic acid), and immunoglobulin G is reported. Poly(ethylene binding adriamycin on the poly(aspartic acid) chain, showed an excellent water‐solubility despite introduction large amount strongly hydrophobic was found to form micellar structure in aqueous solution. Efficient coupling between achieved via disulfide linkages.
