Abstract
Despite the recent emergence of immune checkpoint inhibitors, clinical outcomes of metastatic NSCLC patients remain poor, pointing out the unmet need to develop novel therapies to enhance the anti-tumor immune response in NSCLC. In this regard, aberrant expression of the immune checkpoint molecule CD70 has been reported on many cancer types, including NSCLC. In this study, the cytotoxic and immune stimulatory potential of an antibody-based anti-CD70 (aCD70) therapy was explored as single agent and in combination with docetaxel and cisplatin in NSCLC in vitro and in vivo. Anti-CD70 therapy resulted in NK-mediated killing of NSCLC cells and increased production of pro-inflammatory cytokines by NK cells in vitro. The combination of chemotherapy and anti-CD70 therapy further enhanced NSCLC cell killing. Moreover, in vivo findings showed that the sequential treatment of chemo-immunotherapy resulted in a significant improved survival and delayed tumor growth compared to single agents in Lewis Lung carcinoma-bearing mice. The immunogenic potential of the chemotherapeutic regimen was further highlighted by increased numbers of dendritic cells in the tumor-draining lymph nodes in these tumor-bearing mice after treatment. The sequential combination therapy resulted in enhanced intratumoral infiltration of both T and NK cells, as well as an increase in the ratio of CD8+ T cells over Tregs. The superior effect of the sequential combination therapy on survival was further confirmed in a NCI-H1975-bearing humanized IL15-NSG-CD34+ mouse model. These novel preclinical data demonstrate the potential of combining chemotherapy and aCD70 therapy to enhance anti-tumor immune responses in NSCLC patients.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is among the most lethal cancers, with a 5-year relative survival rate of 5%. The desmoplastic stroma found in the tumor microenvironment of PDAC is suggested to be partly responsible for the resistance to most therapeutic strategies. This review outlines the clinical results obtained with an immune checkpoint inhibitor in PDAC and discusses the rationale to use a combination of chemotherapy and immune checkpoint therapy. Moreover, essential parameters to take into account in designing an efficient combination have been highlighted.

Abstract
Under cellular distress, multiple facets of normal homeostatic signaling are altered or disrupted. In the context of the immune landscape, external and internal stressors normally promote the expression of natural killer group 2 member D (NKG2D) ligands that allow for the targeted recognition and killing of cells by NKG2D receptor-bearing effector populations. The presence or absence of NKG2D ligands can heavily influence disease progression and impact the accessibility of immunotherapy options. In cancer, tumor cells are known to have distinct regulatory mechanisms for NKG2D ligands that are directly associated with tumor progression and maintenance. Therefore, understanding the regulation of NKG2D ligands in cancer will allow for targeted therapeutic endeavors aimed at exploiting the stress response pathway. In this review, we summarize the current understanding of regulatory mechanisms controlling the induction and repression of NKG2D ligands in cancer. Additionally, we highlight current therapeutic endeavors targeting NKG2D ligand expression and offer our perspective on considerations to further enhance the field of NKG2D ligand biology.

Abstract
There is currently a strong development of therapeutic combinations with checkpoint inhibitors (CPIs). The most promising combinations with CPIs concern anti-angiogenic agents and BRAF/MEK inhibitors. The timing of the initiation of the combination should be particularly well investigated for chemotherapy. Combinations between CPIs raise questions about risk/benefit ratio and overall clinical activity.

Abstract
Background: The experience of using consolidation durvalumab in post-concurrent chemoradiation (CCRT) unresectable stage III non-small cell lung cancer (NSCLC) is rare in real-world clinical practice, and the factors associated with its efficacy are also unclear. We sought to analyze the efficacy of consolidation durvalumab and the factors associated with its efficacy using a multicenter observational study. Methods: The data for 61 patients with post-CCR unresectable stage III NSCLC receiving consolidation durvalumab at the Chang Gung Memorial Hospitals in Linkou, Keelung, Chiayi, and Kaohsiung from November 2017 to March 2020 were analyzed. (3) Results: The median post-CCRT progression-free survival (PFS) and time to metastatic disease or death (TMDD) for consolidation durvalumab were 14.0 months and 16.7 months, respectively. In multiple variant factors analysis, we found that an epidermal growth factor receptor (EGFR) mutation was an independently unfavorable predictive factor for consolidation durvalumab therapy regarding PFS. The median post-CCRT PFS was 6.50 months for EGFR-mutated patients and 33.63 months for EGFR wild-type and unknown patients (HR = 10.47; 95% CI, 4.55–24.07; p < 0.001). Conclusions: Consolidation durvalumab is effective and safe for post-CCRT unresectable stage III NSCLC in clinical practice, but EGFR mutation is an unfavorable factor for consolidation durvalumab. Thus, searching for a better consolidation therapy for EGFR-mutated patients is warranted.

Abstract
Simple Summary Natural Killer (NK) cells are innate lymphocytes that play an important role in the immune response against cancer. Their activity is controlled by a balance of inhibitory and activating receptors, which in cancer can be skewed to favor their suppression in support of immune escape. It is therefore imperative to find ways to optimize their antitumor functionality. In this review, we explore and discuss how their activity influences, or even mediates, the efficacy of various anti-cancer therapies and, vice versa, how their activity can be affected by these therapies. Knowledge of the mechanisms underlying these observations could provide rationales for combining anti-cancer treatments with strategies enhancing NK cell function in order to improve their therapeutic efficacy. Abstract Natural Killer (NK) cells are innate immune cells with the unique ability to recognize and kill virus-infected and cancer cells without prior immune sensitization. Due to their expression of the Fc receptor CD16, effector NK cells can kill tumor cells through antibody-dependent cytotoxicity, making them relevant players in antibody-based cancer therapies. The role of NK cells in other approved and experimental anti-cancer therapies is more elusive. Here, we review the possible role of NK cells in the efficacy of various anti-tumor therapies, including radiotherapy, chemotherapy, and immunotherapy, as well as the impact of these therapies on NK cell function.

Abstract
BACKGROUND Immune checkpoint inhibitors targeting the programmed cell death-1 (PD-1)/PD-1 ligand 1 (PD-L1) axis have shown promising results in patients with nonsmall cell lung cancer (NSCLC). One major PD-L1 inducer is IFNγ, which is secreted by T cells and NK cells. Importantly, IFNγ-induced PD-L1 is one of the major mechanisms by which cancer cells escape host immunity. METHODS Here, we found that the NSCLC cell line, LC-2/ad, has a unique character; the PD-L1 expression in these cells is up-regulated by both IFNγ and epidermal growth factor (EGF). RESULTS Comparative analysis of the cell signaling pathway showed that IFNγ activates STAT1 signaling, while EGF activates AKT, MAPK, and ribosomal protein S6 kinase in LC-2/ad cells. IFNγ-induced PD-L1, but not EGF-induced PD-L1, was clearly blocked by the JAK-STAT inhibitor tofacitinib. Interestingly, IFNγ decreased the expression of NK cell-activating ligands while increasing the expression of MHC class I molecules, resulting in a phenotype that can easily escape from NK cells, theoretically. Finally, we showed that IFNγ stimuli attenuated NK cell-mediated cytotoxicity in LC-2/ad cells, which was, however, blocked by tofacitinib. CONCLUSIONS Taken together, our study shows that tofacitinib blocks the IFNγ-induced transformation from an NK cell-sensitive phenotype to an NK cell-resistant one in IFNγ-reacted LC-2/ad cells, thereby implicating that tofacitinib may be a promising agent to overcome IFNγ-induced tumor immune escape, although it may be adapted to the limited number of NSCLC patients.
