Various subsets of T-cell receptor (TCR) γδ⁺ T cells expressing distinct TCR-Vγ chains are found in many different anatomical locations. These TCR γδ⁺ T cells perform multiple functions as an essential part of the immune system. In particular, protection against malaria infection by TCR γδ⁺ T cells is of special interest. In the present study, we confirmed that the Vγ7⁺ γδ T cells, which are an unconventional subset usually localized within the intestine, are recruited to the liver and spleen at the late stage of malaria infection, and contribute to protection against malaria infection via a multifunctional approach in apoptosis inhibitor-deficient mice.
