Research data from University of Ulm update understanding of bioengineering

"Heat shock proteins (Hsp) of the Hsp70/90 families facilitate cellular immune responses to antigenic peptides or proteins bound to them and have therefore been used as vaccine vehicles. We developed an expression system in which chimeric proteins with an Hsp-capturing, viral J domain fused to diverse antigen-encoding sequences form stable complexes with eukaryotic (Hsp70, Hsp73) or bacterial (DnaK) stress proteins and accumulate to high steady-state levels," researchers in Ulm, Germany report. "J domains from different species (viruses/SV40, bacteria/Chlamydia trachomatis or plants/Arabidopsis thaliana) efficiently capture murine or human stress proteins in this...
