2003 SEP 10 - (NewsRx.com & NewsRx.net) -- Researchers have designed a genome-based functional screening approach to vaccine development that combines in vitro assays and DNA immunization.
"A two-step screening strategy was developed to identify strong immunogenic polypeptides with putative vaccine and/or adjuvant activity," scientists in New Zealand report.
"In the first step, a mycobacterial genomic DNA library was screened in vitro to identify plasmids encoding polypeptides that stimulate splenocytes from mycobacteria-immunized mice and T cells from PPD-positive healthy donors to produce interferon-gamma," stated Alain Delcayre and colleagues at Genesis Research and Development. "In the second step, plasmids were selected for their ability to induce protective immunity in a mouse model of tuberculosis following DNA immunization. The potential of this approach is ...
