Scientists showed that curcumin, the main ingredient of the Indian herb turmeric, restores key immune cells that fight off cancer.

The immune system of patients with advanced cancer is significantly weakened, mostly because the main cells that fight off tumors either cannot proliferate anymore or have died off. Curcumin was previously shown to have anti-tumor activity but its effects on the immune system were unknown - until now.

Gaurisankar Sa and colleagues showed that curcumin boosts the immune system of tumor-bearing mice by restoring key immune cells called CD4 and CD8 T cells. The scientists also showed that curcumin increases the production of proteins that cause immune cells to proliferate and reduces the production of proteins that destroy immune cells.

The American Society for Biochemistry and Molecular Biology is a nonprofit scientific and educational organization with over 11,900 members in the United States and internationally. Most members teach and conduct research at colleges and universities. Others conduct research in various government laboratories, nonprofit research institutions and industry. The Society's student members attend undergraduate or graduate institutions.

Founded in 1906, the Society is based in Bethesda, Maryland, on the campus of the Federation of American Societies for Experimental Biology. The Society's purpose is to advance the science of biochemistry and molecular biology through publication of the Journal of Biological Chemistry, the Journal of Lipid Research, and Molecular and Cellular Proteomics, organization of scientific meetings, advocacy for funding of basic research and education, support of science education at all levels, and promoting the diversity of individuals entering the scientific work force.
