英文摘要
PROJECT SUMMARY
The 2015 UNAIDS report estimates that over 35 million people are infected with HIV. Despite the lack
of a sterilizing cure, antiretroviral drug therapies (ART) effectively suppress viral replication in infected
individuals. However, only 17 million infected individuals have access to ART. Additionally, ART is a
life-long therapy that requires daily administration and is associated with a range of unwanted side
effects. Broadly neutralizing antibodies (bNAbs) may be able to supplement or replace ART. Several
such antibodies have already shown promise in human clinical trials, where a single dose can decrease
viremia in HIV-1 infected individuals. However, viral rebound occurs rapidly during treatment as the
bNAb concentration decreases and resistant variants are selected. Adeno-associated virus (AAV)
vectors can express bNAbs for years at concentrations capable of limiting viral evolution and
maintaining viral suppression. However, we and other groups have shown the emergence of anti-drug
antibodies (ADA) to expressed bNAbs that can limit their expression. In this K99/R00 proposal, I will
address three key questions associated with the use of AAV-delivered bNAbs in a functional cure. 1)
Which bNAbs have biophysical and neutralization properties consistent with suppressing an
established infection? 2) Can vector and AAV capsid optimization increase bNAb expression and help
limit the host ADA response? 3) Can AAV-delivered bNAbs suppress an established SHIV infection in
rhesus macaques, obviating the need for ART? By answering these questions, we will determine how
best to use AAV vectors to treat an AAV infection, and provide insight for investigators using AAV in
other clinical contexts. My research with AAV and HIV-1 systems and my development of non-human
primate projects as a Ruth L. Kirschstein Fellow have provided me with the training necessary to
complete these aims. TSRI provides an outstanding research environment for collaborative science,
especially in the HIV field. Moreover, I will attend courses offered at TSRI and Cold Spring Harbor that
will provide further training on becoming an independent investigator. My mentor, Dr. Farzan, along
with my Scientific Advisory Committee consisting of Drs. Ron Desrosiers, Susana Valente and Hyeryun
Choe, are committed to providing me with an excellent training in developing my research goals and
improving my grant writing skills for future R01 submissions. The skills I acquire during the training
phase will serve as a foundation for my own research program during the independent phase, with the
specific goals of developing new gene-therapy vectors and applying these vectors to human diseases.
