Inflammasome may play a key role in triggering immune response to cancer

The inflammasome — a protein signaling network that is activated to rid the body of virus or bacteria-infected cells — may play an important role in triggering an immune response to cancer and causing an existing class of drugs to work better against cancers.

Research details new strategy for overcoming treatment resistance by zeroing in on dendritic cells

Many of the most aggressive and hard-to-treat cancers are highly effective at blocking T cells, known as the foot soldiers of the immune system, from reaching and responding to tumors.

Myeloid cells can suppress immune response, promote brain metastasis

Scientists have long believed that the brain protects itself from an aggressive immune response to keep down inflammation. However, that evolutionary control may work against it when a cancer cell attempts to spread to the brain, researchers at the University of Notre Dame have discovered.

Researchers identify effective way to protect vulnerable people from COVID-19

T-cells taken from the blood of people who recovered from a COVID-19 infection can be successfully multiplied in the lab and maintain the ability to effectively target proteins that are key to the virus's function, according to a new study published Oct. 26 in Blood.
