New Drug Has Potential to Protect Brain Cells from Traumatic Injuries

Traumatic brain injuries (TBIs), caused by everything from falls to being hit by moving objects to car crashes, cause nearly a third of all injury-related deaths in the U.S. Millions of survivors struggle with impaired thinking and movement, personality changes or depression.

HIV Hidden in Patients’ Cells Can Now Be Accurately Measured

HIV Hidden in Patients’ Cells Can Now Be Accurately Measured

This human T cell (blue) is under attack by HIV (yellow), the virus that causes AIDS. The virus specifically targets T cells, which play a critical role in the body's immune response against invaders like bacteria and viruses.

Until now, researchers haven't been able to accurately quantify a latent form of HIV that persists in patients' immune cells. This hampers doctors' ability to assess the effectiveness of a particular treatment and select better alternatives.

A foundation that has set a goal this decade of identifying 50 inventors who will shape the next 50 years has added its second University of Texas at Austin faculty member to the list. The Gordon and Betty Moore Foundation announced Livia Eberlin, assistant professor in the Department of Chemistry, is one of this year's five Moore Inventor fellows.

New Flu Drug Informed by UT Austin Professor's 40-year-old Basic Research

New Flu Drug Informed by UT Austin Professor's 40-year-old Basic Research

Last year, Texas saw a particularly deadly flu season. Now, there is a new Federal Drug Administration-approved treatment, Xofluza, designed to catch the flu in its early stages and stop it from spreading. The drug is thanks in large part to professor emeritus Robert Krug's basic research, undertaken almost 40 years ago.

A team of researchers at The University of Texas at Austin has demonstrated a new way to sequence proteins that is much more sensitive than existing technology, identifying individual protein molecules rather than requiring millions of molecules at a time. The advance could have a major impact in biomedical research, making it easier to reveal new biomarkers for the diagnosis of cancer and other diseases, as well as enhance our understanding of how healthy cells function.

Making Cancer’s Metabolism More Normal Blocks Drug Resistance

Making Cancer’s Metabolism More Normal Blocks Drug Resistance

Updated on August 31, 2018: This release was updated to correct mistakes in descriptions of the way cancer cells develop drug resistance and the way that anti-cancer drug DCA affects the metabolism of cancer cells.

A new drug lead shows promise that it could reduce the size of cancerous tumors much more effectively than current treatments.

By altering the genetic code in bacteria, researchers at The University of Texas at Austin have demonstrated a method to make therapeutic proteins more stable, an advance that would improve the drugs' effectiveness and convenience, leading to smaller and less frequent doses of medicine, lower health care costs and fewer side effects for patients with cancer and other diseases.

The 40 Year-old Discovery Behind A Promising New Flu Drug

The 40 Year-old Discovery Behind A Promising New Flu Drug

A discovery that Robert Krug, a University of Texas at Austin molecular biologist, made decades ago has led to the development of a new drug to fight flu infections more effectively than existing drug treatments.

A Score to Settle with Cancer (Audio)

A Score to Settle with Cancer (Audio)

Jonathan Sessler was a college student when he was first diagnosed with Hodgkin's lymphoma. Fortunately, he was also a chemistry major. After surviving radiation therapy, relapsing and then surviving extremely high doses of what he calls "rat poison" (a.k.a. chemotherapy), his oncologist challenged him: "You're a chemist. Find new cancer drugs."

Ancient Enzyme Could Boost Power of Liquid Biopsies to Detect and Profile Cancers

Ancient Enzyme Could Boost Power of Liquid Biopsies to Detect and Profile Cancers

Scientists are developing a set of medical tests called liquid biopsies that can rapidly detect the presence of cancers, infectious diseases and other conditions from only a small blood sample. Researchers at The University of Texas at Austin are developing a new tool for liquid biopsy that could soon provide doctors with a more complete picture of an individual's disease, improving their chances of finding the best treatment, while also sparing patients the pain, inconvenience and long wait times associated with surgical biopsies.
