Borrowing a cancer cell’s disguise, scientists shielded insulin-producing cells from attack by the immune system, a breakthrough that could pave the way for targeted type 1 diabetes treatments without ...

In most solid tumors, high numbers of regulatory T (Treg) cells are associated with poorer outcomes because they dampen the immune system's ability to fight against a tumor. Colorectal cancer, however ...

Work on peacemakers in the immune system won the 2025 Nobel Prize in physiology or medicine. The peacemakers are regulatory T cells, a type of immune cell that calms the immune system after it has ...

Researchers have found a reliable way to grow helper T cells from stem cells, solving a major challenge in immune-based cancer therapy. Helper T cells act as the immune system’s coordinators, helping ...

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients ...

For decades, aging has looked like an unavoidable slide into frailty, driven in part by an immune system that slowly loses ...

Immunotherapy, which uses programmed immune cells to selectively destroy cancer cells, has transformed cancer treatment. However, cancer cells have developed immune evasion strategies, leading to poor ...

A Dartmouth study published in Nature Communications reveals that immune cells in the brain use a surprising two-step process ...

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients ...

Researchers at MIT and Stanford University have developed a new way to stimulate the immune system to attack tumor cells, using a strategy that could make cancer immunotherapy work for many ...

Your immune system is your body’s built-in defense network, working nonstop to protect you from bacteria, viruses, and other ...
