Dimerization of an Immunoactivating Peptide Derived from Mycobacterial hsp65 Using N-Hydroxysuccinimide Based Bifunctional Reagents Is Critical for Its Antitumor Properties
Original language description
We have shown previously that a short pentapeptide derived from the mycobacterial heat shock protein hsp65 can be highly activating for the immune system based on its strong reactivity with the early activation antigen of lymphocytes CD69. Here, we investigated an optimal form of presentation of this antigen to the cells of the immune system. Four different forms of the dimerized heptapeptide LELTEGY, and of the control inactive dimerized heptapeptide LELLEGY that both contained an extra UV active glycine-tyrosine sequence, were prepared using dihydroxysuccinimidyl oxalate (DSO), dihydroxysuccinimidyl tartarate (DST), dihydroxysuccinimidyl glutarate (DSG), and dihydroxysuccinimidyl suberate (DSS), respectively. Heptapeptides dimerized through DST and DSG linkers had optimal activity in CD69 precipitation assay. Moreover, dimerization of active heptapeptide resulted in a remarkable increase in its proliferation activity and production of cytokines in vitro. Furthermore, while DST and DS
