Vγ9Vδ2 T cells are immune effector cells very well-suited for immunotherapy, but clinical results have been disappointing in multiple myeloma (MM) and other cancers. We have shown that Vg9Vd2 T cells are victimized prematurely by the immune suppressive tumor microenvironment (TME) established by myeloma and neighbouring cells in the bone marrow (BM) of MM patients. One major mechanism is the highly redundant expression of multiple immunecheckpoints/immune checkpoint-ligands (ICP/ICP-L) in the TME impairing antimyeloma Vg9Vd2 T-cell immune responses. Another major immune suppressive mechanism is the metabolic reset driven by myeloma cells in the TME to satisfy their energetic needs to the detriment of effector cells. Recently, it has become clear that the ICP/ICP-L circuitry and metabolic checkpoints (MCP) jointly operate in the TME of cancer patients to promote tumor cell growth and suppress antitumor immune responses. In this review, we discuss the possible interactions between ICP/ICP-L and MCP in the TME of MM patients that may compromise the immune competence of BM Vγ9Vδ2 T cells, envisaging novel combination therapies to improve the outcome of immune-based interventions.
