Higher macrophage inflammatory protein (MIP)-1α and MIP-1β levels from CD8(+) T cells are associated with asymptomatic HIV-1 infection
To test the hypothesis that β-chemokine levels may be relevant to the control of HIV in vivo, we compared RANTES, MIP-1α, and MIP-1β production from purified CD8(+) T cells from 81 HIV-infected subjects and from 28 uninfected donors. Asymptomatic HIV(+) subjects produced significantly higher levels of MIP-1α and MIP-1β, but not RANTES, than uninfected donors or patients that progressed to AIDS. In contrast, β chemokines in plasma were either nondetectable or showed no correlation with clinical status. The high β-chemokine-mediated anti-HIV activity was against the macrophage tropic isolate HIV-1(BAL), with no demonstrable effect on the replication of the T-cell tropic HIV-1(IIIB). These findings suggest that constitutive β-chemokine production may play an important role in the outcome of HIV-1 infection

Refining Current Scientific Priorities and Identifying New Scientific Gaps in HIV-Related Heart, Lung, Blood, and Sleep Research.
The National Heart, Lung, and Blood Institute (NHLBI) AIDS Program's goal is to provide direction and support for research and training programs in areas of HIV-related heart, lung, blood, and sleep (HLBS) diseases. To better define NHLBI current HIV-related scientific priorities and with the goal of identifying new scientific priorities and gaps in HIV-related HLBS research, a wide group of investigators gathered for a scientific NHLBI HIV Working Group on December 14-15, 2015, in Bethesda, MD. The core objectives of the Working Group included discussions on: (1) HIV-related HLBS comorbidities in the antiretroviral era; (2) HIV cure; (3) HIV prevention; and (4) mechanisms to implement new scientific discoveries in an efficient and timely manner so as to have the most impact on people living with HIV. The 2015 Working Group represented an opportunity for the NHLBI to obtain expert advice on HIV/AIDS scientific priorities and approaches over the next decade

Unsung Hero Robert C. Gallo
Awarding the Nobel prize in physiology or medicine to Francoise Barré-Sinoussi and Luc Montagnier for the discovery of HIV-1, the causative agent of AIDS, is timely given the harm that the virus continues to inflict on the people of the world.
While these awardees fully deserve the award, it is equally important to recognize the contributions of Robert C. Gallo. Gallo definitively proved HIV-1 as the cause of AIDS through the successful isolation and long-term cultivation of HIV-1 and developed a diagnostic kit that prevented new infections and saved thousands of lives. These contributions, together with Gallo's earlier discovery of interleukin-2 (fundamental for growing HIV-1 in vitro) and of HTLV-1, the first human pathogenic retrovirus, warrant equal recognition
