Changes in natural killer cell activation and function during primary HIV-1 infection.
Background. Recent reports suggest that Natural Killer (NK) cells may modulate pathogenesis of primary HIV-1 infection. However, HIV dysregulates NK-cell responses. We dissected this bi-directional relationship to understand ...
Viral escape from HIV-1 neutralizing antibodies drives increased plasma neutralization breadth through sequential recognition of multiple epitopes and immunotypes.
Identifying the targets of broadly neutralizing antibodies to HIV-1 and understanding how these antibodies develop remain important goals in the quest to rationally develop an HIV-1 vaccine. We previously identified a ...
Ratio of monocytes to lymphocytes in peripheral blood identifies adults at risk of incident tuberculosis among HIV-infected adults initiating antiretroviral therapy.
(Oxford University Press., 2013)
Background. Eight decades ago, the ratio of monocytes to lymphocytes (hereafter, the “ML ratio”) was noted to affect outcomes of mycobacterial infection in rabbits. Recent transcriptomic studies support a role for relative ...
Topical microbicides - What's new?
(Lippincott Williams & Wilkins., 2013)
Topical microbicides are an important, promising but complex HIV prevention technology under development. After 11 disappointing effectiveness trial outcomes of 6 candidate products (some tested as multiple doses and ...
When to start antiretroviral therapy during tuberculosis treatment?
(Lippincott Williams & Wilkins., 2012)
Purpose of review. Effective treatment exists for tuberculosis (TB) and for HIV, but treating both diseases simultaneously presents several challenges. This review assesses the evidence for the timing of antiretroviral ...

Identification of broadly neutralizing antibody epitopes in 1 the HIV-1 envelope glycoprotein using evolutionary models.
(Virology Journal, 2013)
Background: Identification of the epitopes targeted by antibodies that can neutralize diverse HIV-1 strains can provide important clues for the design of a preventative vaccine. Methods: We have developed a computational ...
Comparison of viral env proteins from acute and chronic infections with subtype C human immunodeficiency virus type 1 identifies differences in glycosylation and CCR5 utilization and suggests a new strategy for immunogen design.
(American Society for Microbiology., 2013)
Understanding human immunodeficiency virus type 1 (HIV-1) transmission is central to developing effective prevention strategies, including a vaccine.We compared phenotypic and genetic variation in HIV-1 env genes from ...
Multiple pathways of escape from HIV broadly cross-neutralizing V2-dependent antibodies.
(American Society for Microbiology., 2012)
Broadly cross-neutralizing (BCN) antibodies are likely to be critical for an effective HIV vaccine. However, the ontogeny of such antibodies and their relationship with autologous viral evolution is unclear. Here, we ...
Rapid, complex adaption of transmitted HIV-1 full-length genomes in subtype C-infected individuals with differing disease progression.
(Wolters Kluwer Health., 2013)
Objective(s): There is limited information on full-length genome sequences and the early evolution of transmitted HIV-1 subtype C viruses, which constitute the majority of viruses spread in Africa. The purpose of this ...
