DESCRIPTION (provided by applicant): 
Despite the introduction of highly-active antiretroviral treatment 
(HAART), the proportion of newly HIV-1 infected patients developing 
HIV-associated dementia (HAD) is increasing. Currently, there is no 
effective therapy for HAD. Understanding the evolutionary factors 
driving the emergence of neurovirulent strains during disease 
progression is of pivotal importance to develop a realistic model of 
neuroAIDS. The objectives of the current proposal are to define viral 
evolutionary steps within the central nervous system (CNS) and select 
monocyte/macrophages from bone marrow, gut, lung and blood preceding and
 associated with the onset of neuropathogenesis. The Rhesus macaque 
model of neuroAIDS will be employed to study the evolution of the viral 
quasispecies during disease progression and to track SIV-infected 
macrophage subsets infiltrating the brain. 24 animals will be infected 
with a genetically-defined viral swarm. Peripheral blood and tissue 
samples will be collected over time and used for amplification of a 
3.3kb fragment, including gp160, nef and 5′ LTR, of the viral genome, as
 well as some full-length genomes from selected tissues. We will use 
laser-captured microscopy to isolate viral variants from specific 
productively infected macrophage in the brain at early and end stage 
disease. High-resolution phylogenetic, population genetics, and 
molecular clock algorithms (phylodynamics) will reveal genetic aspects 
of viral reservoirs linked to the onset of a neuropathogenic infection 
that have not yet been characterized because of ethical problems 
associated with tissue sampling in humans. Specific Aim 1 will 
investigate the evolutionary dynamics of SIV in lymphoid and non- 
lymphoid tissues during the course of the infection via longitudinal 
PBMC/tissue macrophages sampling and brain biopsies of monkeys with and 
without CD8+ T-cell depletion; Specific Aim 2 will identify macrophage 
subsets involved in brain entry and acting as potential viral reservoirs
 for brain infection. We will be able to identify tempo and mode of 
brain infection and evolutionary signatures leading to the emergence of 
infectious macrophage-tropic quasispecies that could be used to predict 
and monitor the disease. Equally important is the possibility to use the
 findings into developing drugs that target macrophage and viral 
quasispecies associated to neuropathogenesis. Overall, we will compile 
the most comprehensive database of longitudinal SIV sequences from a 
variety of tissues to date. The PI, although a new investigator without 
previous R01 funding, has significant experience in cutting-edge 
analysis of genetic data, and has assembled a unique and qualified 
interdisciplinary team to assist in the study. PUBLIC HEALTH RELEVANCE: 
This project on HIV-associated dementia examines the evolution of 
immunodeficiency viruses in various tissues involved in brain infection.
 A monkey model of neuroAIDS is used that mimics the course of HIV 
infection in humans. The result will be a description of the genetic 
basis for the onset of dementia in patients with AIDS leading the way to
 the development of new diagnostic and therapeutic tools.
