J Hematol Oncol. Adoptive transfer of autologous natural killer cells leads to high levels of circulating natural killer cells but does not mediate tumor regression. Despite the immunosuppressive environment of solid tumors, NK cell activity/infiltration has been correlated with improved prognoses in humans. Cao B, et al. Provided by the Springer Nature SharedIt content-sharing initiative. Ruggeri L, et al. It was proposed that the cytokine pre-activated NK cells were memory-like with an enhanced response to cytokine or activating receptor re-stimulation weeks or months after the initial pre-activation [84]. They showed that infusion of NK cells from HLA-haploidentical donors combined with subcutaneous IL-2 administration after a pre-conditioning regimen of high-dose cyclophosphamide and fludarabine resulted in successful in vivo expansion of donor NK cells and the induction of complete remission in 5 out of 19 patients with poor-prognosis acute myeloid leukemia (AML) [5]. NK cell progenitors progress through distinct developmental stages and gradually acquire the expression of surface receptors that define NK cell identity such as NK1.1 and CD56 and/or regulate their effector functions such as CD16 and NKp46 [19]. Clin Cancer Res. Xu Y, et al. 2016;7:105. The current source and characteristics of NK cells for immunotherapies, expansion, and activation approaches are given in Tables 3 and 4. 2017;77(20):566475.

It is now understood that the adaptive-like NK cells express the activating receptor NKG2C and that the adaptive nature of NKG2C+ NK cells attributes to the non-classical MHC I molecule HLA-E presenting CMV-specific viral peptide to NKG2C [22]. Current challenges 2015;17(5):61320. Overall, these results indicate that NK cells can invade some solid tumors. When NK cells infiltrate solid tumors, high numbers of NK cells may be associated with better survival. However, in most cases, anti-tumor properties of NK cells are attenuated at the tumor bed. 2010;651:6177. Many efforts are emerging for developing and engineering NK cell-based cancer immunotherapy.

IL-21 has cumulative activation effect in combination with IL-2 [119] or IL-15. It was hypothesized that once bound to mesothelin-overexpressing tumor cells, furin-mediated cleavage would release CXCL16 from the NRPbody and thereby recruit NK cells to the tumor sites [90]. PubMed There are also many ongoing clinical trials to evaluate the safety and efficacy of tumor-targeting CAR-NK cells, including using HER2-specific CAR-NK cell to treat advanced or metastatic HER2-expressing solid tumors (NCT04319757), ROBO1-specific CAR-NK cell to treat a broad spectrum of solid tumors (NCT03940820), and MUC1-specific CAR-pNK to treat patients with MUC1-positive relapsed or refractory solid tumor (NCT02839954).
