Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ultimately lose function during viral infection, findings that could improve ...

Progressive multifocal leukoencephalopathy (PML) is a rare but serious brain infection. It gradually destroys brain tissue ...

A new study identifies an extreme but effective way that brain immune cells can prevent the parasite Toxoplasma gondii from spreading: they kill themselves to eliminate the dangerous microbes they ...

Scientists uncover a new “recipe” that shows how exhausted T cells can be reprogrammed to regain their ability to attack tumors.

Powerful white blood cells referred to as CD8 killer T cells enable the body to control infections and fight cancer. But when they become exhausted, they can become dysfunctional and ineffective.

Immune cells in the brain that go rogue contribute to the death of neurons, so getting rid of them may slow the progression of neurodegenerative conditions like amyotrophic lateral sclerosis ...

When food is scarce, stress hormones direct the immune system to operate in "low power" mode to preserve immune function ...

It is hoped that in the next few years, the vaccine could replace multiple jabs for winter respiratory infections.

Scientists discovered key genetic factors that determine whether a T cell acts as a powerful disease fighter or enters an ineffective, exhausted state. Turning off two transcription factors allowed ...

Experts at Stanford Medicine in the US have developed a universal vaccine that could be given as a nasal spray and could protect against a wide range of respiratory viruses ...

Therapeutic vaccines are advancing in oncology and HIV, with the aim of retraining immune responses to target tumors and persistent viral reservoirs with precision.

Researchers at the University of Virginia School of Medicine have identified a specific enzyme inside immune cells that keeps Toxoplasma gondii, one of the most common brain parasites on the planet, ...
