Single Injection Alleviates Chemotherapy Pain for Months in Mice

Source: University of California San Diego School of Medicine
Researchers at University of California San Diego School of Medicine have found a new way to block a root cause of pain. The key is a naturally occurring protein called apolipoprotein A-I binding protein (AIBP). AIBP binds to toll-like receptor 4 (TLR4), a protein that sits on the surface of cells like an antenna, searching for signs of infection or tissue damage. The researchers found that treating mice with a single spinal injection of AIBP — and thus switching TLR4 "off" — prevented and reversed inflammation and cellular events associated with pain processing. As reported May 29 by Cell Reports, the treatment alleviated chemotherapy pain in mice for two months with no side effects.
