The AIDS epidemic in humans is well-known. Less known is that every year, millions of cats suffer and die from the disease.
To protect cats against feline AIDS, the Mayo Clinic and colleagues in Japan devised a treatment with a peculiar side effect. They took monkey genes that block HIV infection and injected them into cat eggs. Kittens born from those eggs produced AIDS-resistant protein in the same cells that get infected, effectively shielding them from the disease. Their offspring are also immune.
To tell the treated cats from the untreated ones, scientists added another simple ingredient to the mix: jellyfish genes, which make the modified cells glow a green color.
