Title:
FINDING AND TREATMENT OF INFLAMMATION AFTER BIRTH IN CHIMERIC ANIMAL
Document Type and Number:
WIPO Patent Application WO/2018/139502
Kind Code:
A1
Abstract:
The inventor of the present invention found that chimeric animals suffer from noticeable inflammation, though neither immune response nor inflammation in the fetal period of these animals has been reported hitherto. This is an unexpected finding since chimeric animals in the fetal period were exclusively analyzed in prior studies and thus it is deemed that immunotolerance has been theoretically established therein. The present invention provides a composition for suppressing immune response or inflammation in the fetal period of a born chimeric animal.
