Spread of cancers halted by smart bacteria that trigger immune attack

Bacteria can shrink cancer cellsSTEVE GSCHMEISSNER/SCIENCE PHOTO LIBRARY By Michael Le Page GENETICALLY modified “smart” bacteria injected into tumours can shrink growths and trigger an immune response that stops cancer spreading, tests in animals show. The engineered bacteria exploit the vulnerability of solid tumours to infections. This vulnerability comes about because tumours evolve all kinds… Read More »

Interaction between immune factors triggers cancer-promoting chronic inflammation

A Massachusetts General Hospital (MGH) research team has identified interaction between two elements of the immune system as critical for the transformation of a protective immune response into chronic, cancer-promoting inflammation. In their report published in PNAS, the investigators demonstrate that elevated levels of the immune factor IL-33 and regulatory T cells (Tregs), which suppress the… Read More »

The immune system's fountain of youth

If only we could keep our bodies young, healthy and energetic, even as we attain the wisdom of our years. New research at the Weizmann Institute of Science suggests this dream could be at least partly obtainable in the future. The results of this research, led by Prof. Valery Krizhanovsky and Dr. Yossi Ovadya in… Read More »
