Researchers have identified a combination of existing #cancer drugs that may improve treatment for #tuberculosis. Repurposed drugs enhanced delivery of #antibacterial medications that target tuberculosis-causing #bacteria. Although it is often overlooked in industrialized countries such as the United States, tuberculosis remains one of the deadliest diseases.
