Credit: Frontiers in Immunology (2024). DOI: 10.3389/fimmu.2024.1412221 A research team behind a new study at the Hebrew University of Jerusalem has made an important breakthrough in understanding how immune cells known as T cells are...

Immune cells reprogrammed to kill HIV-infected T cells
There exists a group of HIV-positive people who have the rare ability to naturally control the HIV infection. Now, after years of research, a team of scientists from the Institut Pasteur in Paris, has successfully reprogrammed cells that lack this ability, giving them the same incredible, antiviral potency. Less than one percent of people living...

Researchers discover unique immune cell likely drives chronic inflammation
For the first time, researchers have identified that an immune cell subset called gamma delta T cells that may be causing and/or perpetuating the systemic inflammation found in normal aging in the general geriatric population and in HIV-infected people who are responding well to drugs (anti-retrovirals). Even with effective viral control, HIV-infected individuals are at...

Activation of immune T cells leads to behavioral changes
Scanning electron micrograph of a human T lymphocyte (also called a T cell) from the immune system of a healthy donor. Scientists from the RIKEN Center for Integrative Medical Sciences in Japan and collaborators have found that T cells—immune cells that help to protect the body from infections and cancer—change the body’s metabolism when...
