UCLA researchers have found a way to increase the number of iNKT cells in the body to levels that can fight cancer in animals. The method has proven successful in suppressing the growth of human tumors that were transplanted into animals test subjects. iNKT cells have the ability to target several types of cancer at once, but the problem is that most people have low levels. After several experimental trials, the researchers were able to create a method that permanently increases iNKT cell production in the body. With more work, this could be a lifesaving method for cancer patients in the future.
