Ott Lab News

Bird flu is increasingly making state and national headlines: The first U.S. person with a severe case of the virus died in early January, according to the Louisiana Department of Health. And just days later, the San Francisco Department of Public Health announced its first case—a child with the telltale signs of fever and pinkeye who tested positive for the H5N1, the type of influenza A that causes bird flu. The child has since recovered.

Both of these developments came shortly after California Gov. Gavin Newsom declared a state of emergency in late 2024 to strengthen California’s response to bird flu. The virus has spread in at least 16 states among dairy cattle following its first confirmed detection in Texas and Kansas in March 2024.

But what is the real threat to the average person? And what precautions, if any, should people be taking today as bird flu expands beyond its typical winged victims? Melanie Ott, MD, PhD, director of the Gladstone Institute of Virology, shares insights into the developing situation.

In the decades since antiretroviral therapy became the standard of care for HIV, it has transformed quality of life for people living with the virus.

The life-saving therapy—a combination of many medicines—prevents development of AIDS, improves immune function, and markedly lowers the risk of transmitting the virus to others.

However, antiretroviral therapy is far from an HIV cure, says virologist Melanie Ott, MD, PhD, of Gladstone Institutes.

Earlier this year, the World Health Organization declared an end to the global health emergency for COVID-19. This announcement was quickly followed by the US federal government’s plan to end its own public health emergency declaration for the SARS-CoV-2 virus.

Of course, SARS-CoV-2 is still with us. It is also a matter of when, not if, the next pandemic will emerge. These realities mean that the research advances made by Gladstone scientists over the last three years will continue to impact efforts against existing and new viruses for years to come.

Melanie Ott, MD, PhD, director of the Gladstone Institute of Virology (GIV), reflects on the early days of the pandemic, her team’s biggest contributions to COVID-19 research, and the new directions they are taking to understand the underlying biology of viruses, including coronaviruses and HIV.

Here’s the future: a doctor takes a blood sample from her sick patient. In the lab down the hallway, scientists reset the patient’s blood cells into a developmental blank slate using a cocktail of chemicals. Then, they add a combination of tiny molecules that edit the cells’ DNA. Perhaps this editing process repairs a disease-causing mutation or gives the cells a new ability to ward off infection, inflammation, or cancer. Finally, the embryo-like cells are grown into healthy, adult cells—heart cells to quell heart disease, brain cells to treat Alzheimer’s, or immune cells to shrink a tumor—and infused back into the patient’s body. Or perhaps, the doctor infuses the specially designed molecules that edit cells’ DNA right into the patient, and corrections are made directly inside their body.

He completed his bachelors and master’s in genetic engineering and biotechnology at the University of Dhaka, Bangladesh. He completed a master’s in infection and immunity at Erasmus University in Rotterdam, Netherlands. He performed his PhD research in the Ott lab studying molecular virology, and received his degree from Erasmus University.
