Marijuana component opens the door for virus that causes Kaposi's sarcoma
.... Once a cell is infected, the presence of THC may also promote the cellular events that turn it cancerous, the researchers say. They found that THC also promotes the production of a viral receptor similar to one that attracts a cell-signaling protein called interleukin-8. Previous studies have noted...Altering a protein makes mice less fearful
