MEDICAL RESEARCH - "HIV infection is a manageable disease with the advent and availability of combination antiretroviral therapy (ART). But, when ART is interrupted, the virus quickly rebounds to high levels and again targets the immune system. Therefore, new immunotherapeutic treatments are sought to re-program the immune system to control the virus after ART interruption," said IDM's Tatiana Garcia-Bates.
THE NEW YORK TIMES - The mosquito-borne virus that causes Rift Valley fever may severely injure human fetuses if contracted by mothers during pregnancy, according to new research by IDM's Amy Hartman. "Zika caught everybody by surprise," said Hartman. "If doctors had known about Zika's birth effects, they could have done a lot more to protect pregnant women and babies. With Rift Valley fever, we're trying to get ahead of the curve."
The African Academy of Sciences elected Jean Nachega (IDM and EPI) fellow in recognition of his efforts to develop patient care, teaching, and research around epidemiology and infectious diseases in Africa. In addition, the Academy of Sciences of South Africa - which aims to provide evidence-based scientific advice on issues of public interest - named him a member-elect.
JOURNAL OF VIROLOGY - Using samples from participants in the Multicenter AIDS Cohort study, Garcia-Bates, Palma, Shen, Gambotto, Macatangay, Ferris, Rinaldo, and Mailliard showed that PD-1 activation plays a positive role in initiating the primary T cell response. But later blocking of that pathway can enhance the overall magnitude of the immune system’s ability to remember and respond to HIV.
WESA-FM - Research suggests the Rift Valley Fever can affect developing human fetuses. IDM's Amy Hartman, along with first author Cynthia McMillen who is an IDM postdoc, chose to study Rift Valley’s effects on pregnant rats, since humans and rats have similar placental structures. They found that 65 percent of pups born to infected rats died, even when the mother rats appeared healthy.
POST GAZETTE - Allegheny County health officials are reporting progress in the fight against AIDS by reducing new HIV cases. A key part of this effort is education. The MidAtlantic AIDS Education and Training Center, led by Linda Frank, has been involved in efforts to fight AIDS for the past 30 years. The World AIDS Day 2018 conference “is about the new treatments and advancements to help us get to zero new cases,” says Frank.
JOURNAL OF CLINICAL INVESTIGATION INSIGHT - Jasmine Samal, Samantha Kelly, Ali Na-Shatal, Abdallah Elhakiem, Antu Das, Ming Ding, Anwesha Sanyal, Phalguni Gupta, Kevin Melody, Brad Roland, Watfa Ahmed, Aala Zakir, and Moses Bility developed a potentially novel human immune system–humanized mouse model.
UPMC HEALTH NEWS – In the late 1990s, new and highly potent anti-HIV drugs emerged— including protease and reverse transcriptase inhibitors—which could for the first time control HIV infection. For this 1998 World AIDS Day, Pitt IDM AIDS researcher Charles Rinaldo and the late Bridget Murtagh of the Pittsburgh AIDS Task Force address transmission, drug resistance, and the radically prescient question of whether HIV could be cured.
IDM's DERRICK MATTHEWS explains Pitt Public Health's work on HIV/AIDS and where we are today. "If your’e a black gay man in the U.S., you have a one in two change
in your lifetime of becoming HIV positive…short of the cure that we’re looking for, the biology is way ahead of the social implementation science."
IDM's DERRICK MATTHEWS demystifies infectious diseases and microbiology with a basic overview of the fields, how they are practiced, and how disease is spread.
JOURNAL OF VIROLOGICAL METHODS - BURKE, MARQUES, and colleagues discuss anti-dengue NS1-specific IgG and IgG3 as potential biomarkers of long-term and recent (less than 6 months) DENV infections, respectively.
THE LANCET - MARQUES and BURKE comment about two Zika vaccines in clinical development and describe the challenges ahead.
PUBLIC LIBRARY OF SCIENCE - Magalhaes, Braga, Cordeiro, Oliveira, Castanha, Maciel, Amancio, Gouveia, Peixoto-deSilva Jr., Peixoto, Britto, Lima, Lima, and Marques detected the tail end of a Zika epidemic in 2015-16 which was displaced by a chikungunya epidemic. Few dengue cases were identified despite a high number of official dengue notifications in the area during this period. Here they show the important epidemiological features of these cas...
ANTIVIRAL RESEARCH - McMillen and Hartman discuss the historical role of Rift Valley Fever (RVF) as a biological weapon and conclude with an outline of the important unanswered questions for ongoing research into this important zoonotic disease.
