What is γδ T Cell?

As the main component of the immune system, T cells protect the body from infections and tumors by a diversity of bio-functions, including recognition and presentation specific antigens, directly killing target cells, secretion cytokines, assisting or inhibiting antibody production by B cells, etc. These functional T cells are distinguished by a variety of surface receptors, biomarkers, and biological activities.

T cell receptor (TCR) on the surface of T cells is a heterodimer composed of four polypeptide chains, α, β, γ, and δ chain. According to the composition of TCR expressed on the surface, T cells are principally divided into αβ T cells, commonly known as T cells expressing αβTCR and accounting for more than 95% of the total number of T cells, and γδT cells, often referred to as expressing γδTCR and accounting for 1%~5% of peripheral blood T cells. γδ T cells perform a broad range of biological effects, although in small amounts, such as:

  • Recognizing and binding to antigens directly without the presentation of antigen-presenting cells (APC);
  • Functioning as APC and initiate specific immune response;
  • Participating in immune regulation through secreting a variety of cytokines and chemokines;
  • Significant cytotoxicity to lyse target cells through multiple pathways;
  • Activating and promoting the maturation of the dendritic cell.

γδ T Cell Therapy

The extraordinary properties endow γδ T cells with great potential for disease immunotherapy, including tumors, infections, auto-immune disorders. Firstly and most importantly, γδ T cells can effectively and directly recognize and respond to self-antigens expressed by malignant cells in a major histocompatibility complex (MHC)-unrestricted manner, which has been extensively utilized for the development of tumor therapy. Secondly, by producing a variety of cytokines and chemokines, such as interleukins, interferon-γ (IFN-γ), tumor necrosis factor α (TNF-α), γδ T cells recruit and regulate other immunocytes, and enhance the cell-mediated immune response against infections. Moreover, γδ T cells make a great contribution to the epidermal homeostasis, and promote wound healing by locally secreting epithelial growth factors and inflammatory cytokines.

Since the discovery in 1984, γδ T cell therapy has made great advancements for the tumor and cancer treatment over the past few decades. Currently, γδ T cells and their subsets having been researched and performed for the effective treatment of various diseases by numbers of preclinical and clinical trials, mainly including:
