Mechanisms and Functions of γδ T Cells in Tumor Cell Recognition.
γδ T cells are among the first line of defense in the immune system, playing a crucial role in bridging innate and adaptive immunity. Although γδ T cells are crucial for tumor immune surveillance, the complete mechanism by which γδ T cell receptors identify molecular targets in target cells remains unknown. Target cells can produce phosphoantigens (PAgs) via the mevalonate pathway or the methylerythritol phosphate pathway. The BTN3A1-BTN2A1 complex undergoes conformational changes in its extracellular domains upon binding to PAgs, leading to Vγ9Vδ2 T cell recognition. However, the structural basis of how Vγ9Vδ2 T cells recognize changes in this complex remains elusive. This review provides a detailed overview of the historical progress and recent discoveries regarding how Vγ9Vδ2 T cells recognize and target tumor cells. We also discuss the potential of γδ T cells immunotherapy and their role as antitumor agents.
期刊介绍:
Current Oncology is a peer-reviewed, Canadian-based and internationally respected journal. Current Oncology represents a multidisciplinary medium encompassing health care workers in the field of cancer therapy in Canada to report upon and to review progress in the management of this disease.
We encourage submissions from all fields of cancer medicine, including radiation oncology, surgical oncology, medical oncology, pediatric oncology, pathology, and cancer rehabilitation and survivorship. Articles published in the journal typically contain information that is relevant directly to clinical oncology practice, and have clear potential for application to the current or future practice of cancer medicine.
