Philip Ansumana Hull successfully gave an oral presentation on "Metabolic reprogramming of human CD8+ memory T cells through loss of SIRT1" at the 2018 Keystone Symposia on Immunological Memory: Innate, Adaptive and Beyond, February 25-March 2, 2018, at the Hyatt Regency Austin, Austin, Texas.
Aging proteins have long been shown to protect against age-related diseases, such as cancer, neurodegeneration, and cardiovascular disease. A study by researchers at the Gladstone Institutes now reveals that one such protein could also be targeted to rejuvenate cells in the immune system.
The protein in question is called SIRT1, more commonly known for being activated by red wine. In the new study, published in the Journal of Experimental Medicine, the scientists found that it is also involved in how cells in the immune system develop with age.
They wanted to find out how this anti-aging protein affects a specific category of immune cells known as cytotoxic T cells. These cells are highly specialized guardians of the immune system and their role is to kill cells infected by a virus, damaged cells, or cancer cells.Read More

People living with HIV must take a combination of three or more different drugs every day for the rest of their lives. Unfortunately, by following this strict treatment plan, they can suffer from side effects ranging from mild dizziness to life-threatening liver damage. However, if they stop taking the drugs, the virus hiding inside their cells can spontaneously resurface.
In fact, the latent HIV, which can hide in cells for many years, is a critical barrier to a cure. Researchers are exploring two main strategies to tackle this problem––reactivate and destroy the latent virus (called “shock and kill”) or find a way to silence it for good.
In an effort to tackle both strategies, a team of scientists at the Gladstone Institutes studies drugs that disrupt latency and could eventually be used to treat infected patients. They recently discovered how a new drug called JQ1, which is currently in early-phase human cancer trials, can reactivate latent HIV.Read More
SAN FRANCISCO, CA—June 1, 2017
Gladstone Senior Investigator Melanie Ott, MD, PhD, was elected as a fellow of The American Academy of Microbiology (AAM). She was chosen based on her outstanding contributions to microbiology research and her dedicated service to science and the public.
The AAM is the honorific leadership group within the American Society for Microbiology, the world’s oldest and largest life science organization. AAM fellows are elected through a highly selective, peer-review process, based on their records of scientific achievement and original contributions that have advanced microbiology. Each elected fellow has built an exemplary career in basic and applied research, teaching, clinical and public health, and industry or government service. Over the last 50 years, 2,500 distinguished scientists have been elected to the AAM.
“I am honored to be recognized by this remarkable distinction and delighted to be elected to such a prestigious academy,” shared Ott, who is also a professor of medicine at the University of California, San Francisco (UCSF).
Ott’s research focuses on how viruses—HIV, the hepatitis C virus, and most recently, the Zika virus—hijack human cells to promote their own survival. Her work has contributed greatly to what researchers understand about these viruses, and it has inspired new research in each of these fields.
Ott received her MD from the University of Frankfurt/Main in Germany and her PhD from the Picower Graduate School in Manhasset, New York. She has received several honors and awards, including two Young Researcher Awards from the European Conference on Experimental AIDS Research and the Hellman Award from UCSF, which supports the research of promising assistant professors with the capacity for great distinction in their research. She also received the Chancellor’s Award for Public Service from UCSF, which recognized her work as co-founder of a committee at Gladstone that promotes science education in local schools, specifically targeting underserved youth.
The AAM will recognize Ott, along with the 2017 Fellowship class, during a ceremony and reception on June 2, 2017, at the American Society for Microbiology’s ASM Microbe meeting in New Orleans.

Scientists at the Gladstone Institutes discovered that an enzyme called SMYD2 could be a new therapeutic target for flushing out the HIV that hides in infected individuals. Overcoming this latent virus remains the most significant obstacle to a cure.
While drug therapy allows people living with HIV to lead a relatively normal life, it also comes with adverse effects. In addition, patients must stay on the drugs for life to prevent the virus hiding in their body from reactivating. In the early stages of infection, HIV hides in viral reservoirs in a type of immune cells called T cells. This dormant, or latent, virus can then spontaneously reactivate and rekindle infection if drug therapy is stopped.
To eliminate HIV latency, scientists are exploring a “shock and kill” strategy that would use a combination of drugs to wake up the dormant virus, then act with the body’s own immune system to eliminate the virus and kill infected cells. Previous research has had limited success in efficiently reactivating latent HIV, so scientists are working to find new, more effective drugs.Read More
SAN FRANCISCO, CA—January 22, 2015—A study from researchers at the Gladstone Institutes has exposed new battle tactics employed by the hepatitis C virus (HCV). Published in the January 22 issue of Molecular Cell, the investigators created full protein interaction maps—interactomes—of where the virus comes into contact with the host proteins during the course of infection. Through these protein interactions, the scientists not only gained insight into the virus, they also uncovered a common set of host proteins that are targeted by various infections. Their results suggest that these proteins and the cellular processes they govern are the most crucial—in effect, the collective Achilles heel—for both the human body and its viral invaders.Read More

In the latest issue of Molecular Cell, researchers in the laboratory of Gladstone Investigator Melanie Ott, MD, PhD, describe the intriguing behavior of a protein called RNA polymerase II (RNAPII). The RNAPII protein is an enzyme, a catalyst that guides the transcription process by copying DNA into RNA, which forms a disposable blueprint for making proteins. Scientists have long known that RNAPII appears to stall or “pause” at specific genes early in transcription. But they were not sure as why.Read More
