An incredible breakthrough comes from researchers at the University of California San Diego, where scientists have discovered that a harmless plant virus, the cowpea mosaic virus (CPMV), could become a powerful weapon against cancer. Unlike viruses that infect humans, CPMV cannot harm human cells—instead, it reawakens the immune system, training it to hunt down and destroy tumors anywhere in the body. When injected directly into tumors, it summons an army of immune cells including neutrophils, macrophages, natural killer cells, B cells, and T cells, creating a lasting memory that keeps fighting cancer long after treatment. The secret lies in its unique ability to trigger multiple interferons and activate a key immune switch, something no other plant virus has achieved. Low-cost and easily produced with just sunlight, soil, and water, CPMV is now moving toward human clinical trials, offering hope for a revolutionary, affordable cancer therapy.
