Harnessing the Power of a Parasite that can Stop Pain

Posted by in category: biotech/medical

For the first time, scientists have begun to figure out why the disfiguring skin lesions caused by cutaneous leishmaniasis don’t hurt.

Researchers analyzed leishmaniasis lesions on mouse skin to detect metabolic signaling pathways that differed from uninfected mice. Results suggested the parasites that cause the disease change pain perception—presumably as a way to delay treatment and promote their own survival.

“No one knows why these lesions are painless—but it has been thought that the parasite somehow manipulates the host physiological system,” said Abhay Satoskar, senior author of the study and professor of pathology at The Ohio State University College of Medicine.
