CAR γδ T Cell Functional Test

Online Inquiry

Recent reports have shown that the development of CAR TCR-engineered γδ T cells is a promising method in cellular immunotherapy for the treatment of cancer. However, determining the specific function of engineered γδ T cells also plays an important role in cell development. As a professional CRO company in cell therapy, Creative Biolabs provides customized CAR γδ T cell functional test services to meet our clients’ requirements.

Introduction to CAR Engineered γδ T cell

Rischer et al. demonstrated that peripheral blood-derived Vγ9Vδ2 T cells transduced with retroviral vectors encoding either GD2 or CD19-specific CARs had high CAR expression and could be readily expanded. In vitro tests suggested that CAR-expressing γδ T cells might serve as potent and specific antitumor effector cells. Based on these studies, researches and applications of CAR γδ T cells have been in rapid development. Typically, first-generation CARs had a single CD3-z intracellular signaling domain; they were shown to have poor persistence in vivo. Second-generation and third-generation CARs were created by the addition of one or two costimulatory domains to the CD3-z motif to provide tailored signals to enhance activation and survival. Additionally, because CAR γδ T cells can act as professional antigen-presenting cells, combination therapies with other modalities of immunotherapy such as checkpoint inhibitors, oncolytic viruses, vaccines, or cytokines could synergistically amplify recruitment and function of tumor-infiltrating lymphoid and non-lymphoid cells.

Multiple Functions of γδ T Cell

While γδ T cells clearly show potent antitumor activity, some reports describe the regulatory function of these cells in the tumor microenvironment. Moreover, the application of γδ T cells for CAR T cell cancer therapy has many functional advantages (Figure.1). Thus, the cell functional test is necessary during the process of CAR engineered γδ T cell development. With extensive industrial experience, Creative Biolabs provides high-quality CAR engineered γδ T cell functional test services to global customers.
