Deciphering human γδ T cell response in cancer: Lessons from tumor‐infiltrating γδ T cells
2020
The finding that γδ T cells are present among tumor-infiltrating lymphocytes in humans suggests they participate in tumor immune surveillance, but their relevance is unclear because the relative abundance of tumor-infiltrating γδ T cells correlates with positive or negative, or even do not correlate with prognosis. This likely depends on the fact that tumor-infiltrating γδ T cells may play substantially different effector or regulatory functions, and correlation with patient's prognosis relies on distinct γδ T cell subsets in the context of the tumor. There is interest to exploit γδ T cells in tumor immunotherapy, but to make this approach successful there is urgent need to fully understand…
Analysis of infiltrating γδ T cells in cutaneous melanoma: a hypothetic crosstalk for new immunotherapy
2022
Introduction: Melanoma is one of the most frequently occurring skin cancer and remains an important cause of mortality mainly in Caucasian populations. In clinical practice, the standard treatment for localized melanoma is surgical resection but for metastatic melanoma, few treatments are available, where chemo and radio-therapies are rarely indicated. Immunotherapy has revolutionized the management of metastatic melanoma that, as in others tumors, uses your body's own immune system to help fight cancer. Therapies targeting the immune checkpoint molecules have achieved objective responses in melanoma. Several receptors and/or ligands, such as PDL1, PD-1 and CTLA-4, have been identified as i…
Skewed Differentiation of Circulating Vγ9Vδ2 T Lymphocytes in Melanoma and Impact on Clinical Outcome
2016
OBJECTIVE:The aim of this study was to evaluate over time circulating γδ T lymphocytes in melanoma patients in terms of frequency, effector functions, and relationship with clinical stage and evolution, by comparing preoperative values to those obtained at a mean follow-up of 36 months or in the event of recurrence or disease progression, and to those of healthy controls. Also, we correlated the presence of tumor-infiltrating γδ T lymphocytes with clinical evolution of melanoma. RESULTS:Mean frequencies of circulating γδ T cells before and after melanoma removal were very similar and comparable to healthy subjects, but patients who progressed to stage III or IV showed a significantly decrea…
