DNA Vaccines
Reports by S.G. Liu and co-researchers describe recent advances in DNA vaccines
July 30th, 2008
"Mycobacterium bovis is the causative agent of bovine tuberculosis (bTB). The proteins Ag85B, MPB64, and ESAT-6 are the major immunogenic antigens of M. bovis; these proteins play important roles in inducing immune responses that confer resistance against infections," scientists in Harbin, People's Republic of China report. "In the present study, we used pcDNA3.1(+) as a vector and constructed various DNA vaccines with the genes encoding the three antigens mentioned above. This procedure involved the following steps: fusion of two genes (pcDNA-MPB64-Ag85B, pcMA), fusion of three genes (pcDNA-MPB64-Ag85B-ESAT-6, pcMAE), bivalent combinations (pcDNA-Ag85B + pcDNA-MPB64,...
