PLoS Pathogens: ADCC Develops Over Time during Persistent Infection with Live-Attenuated SIV and Is Associated with Complete Protection against SIVmac251 Challenge

See on Scoop.itVirology and Bioinformatics from Virology.ca

“Here we show that live-attenuated SIV induces progressive increases in ADCC over time, and that the development of these antibodies is dependent upon the persistent replication of the vaccine strain. In two different experiments, the animals immunized with live-attenuated SIV that remained uninfected after pathogenic SIV challenge had higher measures of ADCC than those that became infected. Our results suggest that antibodies contribute to protection by live-attenuated SIV, and that persistent stimulation of antibody responses may be essential for HIV-1 vaccines to induce high ADCC activity.”

 

Shit HOT results, in that they demonstrate that – as some have said repeated ly over years – that neutralising Ab are NOT necessarily the Holy Grail, and that ADCC and other mechanisms are also really important.  Good Stuff…B-)
