New approach could slow colon cancer metastasis

When cancer metastasizes and spreads throughout the body, it can severely change the prognosis of the disease. It is estimated that metastasis is responsible for 90 percent of cancer deaths.

Rare disorder of fat metabolism can cause chronic hyperreaction of the immune system

A congenital disorder of the fat metabolism can apparently cause chronic hyperreaction of the immune system. This is the conclusion reached by researchers from the University of Bonn in a recent study.

STING protein activates a pathway that kills tumor-fighting immune cells

The immune protein STING has long been noted for helping protect against viruses and tumors by signaling a well-known immune molecule. Now, UT Southwestern scientists have revealed that STING also activates a separate pathway, one that directly kills tumor-fighting immune cells.

Fault in RNA quality control system causes haywire production of toxic proteins

Osaka, Japan - Researchers at Osaka University have identified a fault in the RNA quality control system of cells that leads to the haywire production of toxic proteins in frontotemporal lobar degeneration and amyotrophic lateral sclerosis (FTLD/ALS).

Eliminating tumors with engineered ‘off-the-shelf’ therapeutic T cells

Personalized cancer treatments are no longer just options of the future. In the past few years, researchers have made significant progress in 'teaching' the body's immune T cells to recognize and kill specific cancer cells, and human clinical trials have shown that this approach can successfully eliminate tumors
