We all want a well-functioning immune system to help us fight invasive bacteria and viruses and recover faster from illness.

Scientists at McGill University have discovered a surprising new ability of immune cells that could change how we understand ...

T cell immunity constitutes a central pillar of the adaptive immune response to SARS-CoV-2, acting in concert with antibodies to prevent severe disease. CD4⁺ helper T cells orchestrate antiviral ...

For decades, scientists have known that a protein made by T cells and natural killer (NK) cells in the immune system, called ...

A review finds that programmed cell death can promote immune evasion or antitumour immunity in oropharyngeal cancer depending on pathway and tumour context.

Investigators from Mass General Brigham have developed a way to promote antitumor immunity by hijacking cellular machinery within cancer cells. The study demonstrated that inducing cancer cells to ...

Microparticles made from red blood cells deliver haem to the nucleus of dendritic cells, activating a pathway that boosts ...

When viruses invade a plant, you might expect an all-out immune war. But new research published in Science shows that, much like in humans, too strong an immune response can actually do more harm than ...

Detailed immune profiling in long-term care populations reveals that SARS-CoV-2 vaccines and infections drive powerful virus-specific responses while leaving lifelong common cold immunity largely ...

Rooted in place, plants have little ability to flee dangerous situations. Additionally, their lack of a dedicated immune system means that, to combat an infection, every cell needs to be able to mount ...
