Researchers artificially generate immune cells integral to creating cancer vaccines

(New York, NY – August 14, 2018)– For the first time, Mount Sinai researchers have identified a way to make large numbers of immune cells that can help prevent cancer reoccurrence, according to a study published in August in Cell Reports.

The researchers discovered a way to grow the immune cells, called dendritic cells, at large scale in the lab to study them for their potential use in highly refined cancer vaccines to prevent patients’ cancer from coming back. Dendritic cells are very rare in the body, so it has not been possible to isolate them from patients for generating vaccines without great expense and highly complicated methods.

The ability to grow many types of dendritic cells, which act as sentinels that warn the immune system to gear up with weapons specific to the disease it is attacking, will allow researchers to study their roles in the immune system. This discovery is especially important because dendritic cells aren’t limited to one type of cancer and can attack all types of cancer with very limited side effects.

“The ability to generate large numbers of distinct types of human dendritic cells in vitro is critical for accelerating our understanding of dendritic
