Multiple myeloma and AL amyloidosis are incurable cancers of blood cells. These blood cells are called plasma cells. There is only one therapy that is available for AL amyloidosis patients. In severe stages, AL amyloidosis patients survive less than one year. Amyloidosis plasma cells cause damage to the body by spilling in the blood a sticky protein. These sticky proteins attach to each other and build up in the heart. Buildup of proteins in the heart causes progressive poor function. AL amyloidosis is a major cause of malfunctioning of the heart and death. To cure AL amyloidosis, we need drugs that 1- stop plasma cells from spilling sticky proteins; 2- kill the cancer plasma cells; and 3-remove the buildup of sticky proteins from the heart. These drugs do not exist, because we do not know how sticky proteins get spilled and why the build-up is not removed.Recently, our lab found out how sticky proteins get out of amyloidosis plasma cells. We also showed that if we stop this process, cancer cells die. Finally, we discovered that cleaner cells that should remove sticky proteins from the heart are reduced and do not function in amyloidosis patients. Based on these data, we will make two novel drugs. One will stop spillage of sticky proteins and kill cancer cells. The other will remove sticky protein from the heart without the need of cleaner cells. Our work is doable and will create therapeutic options for AL amyloidosis patients that could cure their disease.
