Mice whose tumors had been surgically removed also showed comparable improvements after the treatment, the University of California San Diego team found.), a species of legume that includes the subspecies commonly known as black-eyed peas.– a treatment that helps the body's own immune system find and destroy cancer.
The researchers explain that since it's a plant virus, the cowpea mosaic virus can't infect mammals, yet mouse immune systems still tend to identify it as foreign. "Here, we do not treat established tumors or metastatic disease – we prevent them from forming. We are providing a systemic treatment to wake up the body's immune system to eliminate the disease before metastases even form and settle," SteinmetzSteinmetz and her colleagues began the new study by cultivating black-eyed pea plants in the lab and infecting them with the cowpea mosaic virus.
Compared with control groups of untreated mice, those with the nanoparticle treatment showed reduced tumor growth and increased survival rates.
