people don't have the same amount of chronic pain and inflammation. they've seen that in arthritis. this took mice and knocked that portion of the receptor out, indeed the mice had less pain. they further went and were able to block this pore with a drug, and the same thing, these mice had less pain. so this is hopeful in the development of new drugs that target just this section of the receptor, can we give people pain relief without side effects which would be great. jenna: i only have about 30 more seconds here. did you think this is on the path towards more designer drugs. >> absolutely. jenna: drugs really developed for someone's genetics. >> absolutely. that we can look and see, gee, you've got this pattern we can give you this medication and it's going to work better for you. which would be amazing. it's hopefully the future of medicine. jenna: very interesting innovation there. so far only in mice, this is a very limited study but one we thought was worth talking about. dr. london nice to see you again. >> very nice to see you too,
