In recent years, γδ T cells attract a lot of people's attention due to their efficient in vitro tumor killing activities. As a consequence, many researchers are currently studying the tumor killing function of γδ T cells in clinical trials. Although the reported benefits are modest, these studies have revealed that large γδ T-cell infusions were well tolerated. Many studies also demonstrated that γδ T cells not only can be used as effector cells, but also used as a novel cellular vaccine for the treatment of cancer patients. As a leading CRO company, Creative Biolabs provides a range of γδ T cell development services for vaccine development.
