In line with our data, by using murine mammary tumor models, Rong Jin et al. demonstrated that OA did not induce αβ-T cell death.36 Hu et al. also demonstrated that the use of PA at doses below 400 μM did not influence CD8 T cell activation and proliferation.37 Taken together, our studies imply that αβ-T cells might be less vulnerable to FAs than Vγ9Vδ2-T cells. Here, CD8A is linked to breast cancer.
