Beta blockers can repair malformed blood vessels in the brain
Propranolol, a drug that is efficacious against infantile haemangiomas (''strawberry naevi'', resembling birthmarks), can also be used to treat cerebral cavernous malformations, a condition characterised by misshapen blood vessels in the brain and elsewhere. This has been shown by researchers at Uppsala University in a new study published in the scientific journal Stroke. (2021-02-23)

Innate immune system worsens the situation in severe COVID-19
In patients with severe COVID-19, the innate immune system overreacts.

Molecule holds promise to reprogram white blood cells for better cancer treatment
Cancer immunotherapy using ''designer'' immune cells has revolutionized cancer treatment. In this type of therapy, T cells, a type of white blood cell, are collected from a patient's blood and genetically engineered to produce T cells carrying a synthetic molecule termed chimeric antigen receptor (CAR) that enables T cells to recognize and destroy cancer cells. Then these genetically modified CAR T cells are expanded and infused back to the patient. (2020-12-14)

New study points to a better way to ward off asthma triggers
Every day, ten Americans die from asthma. While quick-acting inhalers and medications can reduce inflammation during an asthma attack, people with asthma have few tools to prevent the next attack from coming. Now researchers at La Jolla Institute for Immunology (LJI) have discovered that blocking two immune molecules at the same time is key to preventing asthma attacks in a mouse model. (2020-11-11)

Researchers discover enzyme suppressing immune response to viral infections
Viruses such as HIV, hepatitis B and hepatitis C evade or disrupt the immune system to create persistent infections. These viruses remain a serious health threat, but researchers from the University of Missouri School of Medicine have discovered how an enzyme that regulates several cellular processes might be a key target to preventing viruses from disarming the human immune response. (2020-11-10)

Fighting Zika? Call in the T cells
In a new Science Advances study, Shresta and her colleagues at LJI report that the immune system's T cells have the power to prevent Zika infection in mice. This finding suggests that effective Zika vaccines need to activate T cells to work alongside antibodies. (2020-11-04)

How the immune system remembers viruses
For a person to acquire immunity to a disease, T cells must develop into memory cells after contact with the pathogen. Until now, the number of cells that do this was believed to depend above all on the magnitude of the initial immune response. A team of researchers at the Technical University of Munich (TUM) has now called this into question. (2020-11-02)

Diabetes researchers spot dangerous T cells in the pancreas -- even in healthy people
It's long been thought that having 'autoreactive' T cells in the pancreas was a sure sign of type 1 diabetes. Yet a new study led by scientists at La Jolla Institute for Immunology (LJI) shows that even healthy people have these cells lurking in the pancreas -- in surprisingly high numbers. (2020-10-16)

Cancer-killing T cells 'swarm' to tumors, attracting others to the fight
When immune system T cells find and recognise a target, they release chemicals to attract more T cells which then swarm to help subdue the threat, shows a new study published today in eLife. (2020-10-13)
