Chikuie E, Saeki Y, Tanabe K, Ota H, Tanaka Y, Ohdan H. The involvement of circulating CD69+ CD56bright natural killer cells in weight loss before bariatric surgery: A retrospective cohort study. Medicine (Baltimore) 2023; 102:e34999. [PMID: 37832122 PMCID: PMC10578777 DOI: 10.1097/md.0000000000034999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Accepted: 08/08/2023] [Indexed: 10/15/2023] Open
Abstract
As the impact of the immune system on weight loss prior to bariatric surgery has never been proven, we elucidated the clinical utility of the immune system as an indicator of preoperative weight loss before bariatric surgery. We examined the relationships between preoperative weight loss and biochemical and clinical data at the initial visit in 34 obese patients. Patients were divided according to preoperative weight loss, and peripheral blood mononuclear cells were compared using flowcytometry. The Δpreoperative excess weight loss [Δpre-EWL: pre-EWL (%)/period of preoperative weight loss (days)] showed negative correlations with total and subcutaneous fat area (P = .02, r = -0.41, P = .02, r = -0.42 respectively). The Δpre-EWL and Δpreoperative total weight loss (Δpre-TWL) were negatively correlated with white blood cell count, lymphocyte count, and C-reactive protein (CRP) levels at the initial visit (Δpre-EWL; P = .02, r = -0.37, P = .01, r = -0.41, P = .008, r = -0.45, Δpre-TWL; P = .01, r = -0.40, P = .01, r = -0.42, P = .01, r = -0.42, respectively). Multivariate regression modeling showed that both Δpre-EWL and Δpre-TWL were significantly associated with lymphocyte count (Δpre-EWL; P = .01, Δpre-TWL; P = .01). A comparison between the high (Δ pre-EWL > 0.098) and low weight loss group (Δ pre-EWL < 0.098) demonstrated a significant difference in the expression of the activation marker CD69 on CD56bright Natural killer (NK) cells (P = .01), whereas there was no difference in the frequency of T cells, Natural killer T cells, or NK cells. Additionally, high CRP levels were associated with CD69 expression in CD56bright NK cells (P = .01, R = 0.57). Peripheral lymphocytes, especially CD69-positive CD56bright NK cells, are involved in preoperative weight loss after bariatric surgery, and systemic inflammation may inhibit weight loss before surgery.

Abstract
BRAF(V600E) is a major oncogenic mutation found in approximately 50% of human melanoma that confers constitutive activation of the MAPK pathway and increased melanoma growth. Inhibition of BRAF(V600E) by oncogene targeting therapy increases overall survival of patients with melanoma, but is unable to produce many durable responses. Adaptive drug resistance remains the main limitation to BRAF(V600E) inhibitor clinical efficacy and immune-based strategies could be useful to overcome disease relapse. Tumor microenvironment greatly differs between visceral metastasis and primary cutaneous melanoma, and the mechanisms involved in the antimetastatic efficacy of BRAF(V600E) inhibitors remain to be determined. To address this question, we developed a metastatic BRAF(V600E)-mutant melanoma cell line and demonstrated that the antimetastatic properties of BRAF inhibitor PLX4720 (a research analogue of vemurafenib) require host natural killer (NK) cells and perforin. Indeed, PLX4720 not only directly limited BRAF(V600E)-induced tumor cell proliferation, but also affected NK cell functions. We showed that PLX4720 increases the phosphorylation of ERK1/2, CD69 expression, and proliferation of mouse NK cells in vitro. NK cell frequencies were significantly enhanced by PLX4720 specifically in the lungs of mice with BRAF(V600E) lung metastases. Furthermore, PLX4720 also increased human NK cell pERK1/2, CD69 expression, and IFNγ release in the context of anti-NKp30 and IL2 stimulation. Overall, this study supports the idea that additional NK cell-based immunotherapy (by checkpoint blockade or agonists or cytokines) may combine well with BRAF(V600E) inhibitor therapy to promote more durable responses in melanoma.

Abstract
NK cells have become a subject of investigation not only in the field of tumor immunology and infectious diseases, but also within all aspects of immunology, such as transplantation, autoimmunity, and hypersensitivity. Our early studies aside from investigating NK cell activity in experimental animals and humans included studies of perforin expression and modulation in this lymphocyte subset. As NK cell activity is modified by their environment, we showed clinical stage-dependent impairment of their activity and in vitro effect of different sera, Th1 cytokines, and their combination in breast cancer, Hodgkin's disease, and non-Hodgkin's lymphoma patients, especially with respect to metabolic and cell membrane changes of peripheral blood lymphocytes evaluated by spontaneous release of the enzyme lactate dehydrogenase (LDH) that led to the correction of the LDH enzyme release assay for natural cytotoxicity. By long-term immuno-monitoring of patients with malignancies, we also showed the kinetics of NK cell modulation during chemo-immunotherapy. In our more recent studies, we give data of NK function and novel families of NK cell receptor expression in healthy individuals that may be of help in NK cell profiling, by giving referent values of basic and cytokine-induced expression of some NK cell receptors either in evaluation of disease or in immuno-monitoring during cytokine therapy of patients with malignancies. Moreover, we give novel aspects of modulation of NK cell activity by cytokines approved for immunotherapy, IFN and IL-2, in melanoma and other malignancies with respect to alterations in new activating (NKG2D and CD161) and inhibitory (CD158a and CD158b) receptor characteristics and signaling molecules in CD16- and CD56-defined NK cells and their small immunoregulatory and large cytotoxic subsets in peripheral blood and lymph nodes, as NK cell-mediated killing of tumor cells depends on the balance between stimulatory and inhibitory signaling.

Abstract
Abstract
The present study is aimed to examine the possibility of enhancement of natural killer (NK) cell activity in aged C57BL/6 and C3H mice using MGN-3, a modified arabinoxylan from rice bran. Intraperitoneal injection of MGN-3 (10 mg kg−1 per day) caused a remarkable increase in the peritoneal NK activity as early as 2 days (35.2 lytic units), and the level remained elevated through day 14. The control aged mice had a level of 5.8 lytic units. Enhancement in NK activity was associated with an increase in both the binding capacity of NK cells to tumour targets and in the granular content as measured by BLT-esterase activity. Treatment did not alter the percentage of peritoneal NK cells. Data showed that peritoneal macrophages inhibit NK activity. In conclusion, MGN-3 enhances murine NK activity of aged mice and may be useful for enhancing NK function in aged humans.

Abstract
The aim of this study was to estimate the distribution and density of a representative set of activating and inhibitory receptors on gated natural killer (NK) cells, as well as on their bright and dim subsets, and to correlate the receptor expression with NK cell activity for healthy individuals on CD3(-)CD16(+) NK cells. We show that in 43 healthy controls NK cell activity against K562 target cells was 37.34% (E:T, 80:1) by standard chromium release assay. The expression of receptors on NK cells and their subsets was analyzed by flow cytometry. The cytotoxic CD3(-)CD16(bright) NK subset constituted 78.97%, while the regulatory CD3(-)CD16(dim) NK subset constituted 21.03% of NK cells. We show the distribution of NKG2D, CD161, CD158a, and CD158b receptors on CD3(-)CD16(+) NK cells in peripheral blood lymphocytes (PBLs), on gated NK cells, and on the CD3(-)CD16(bright) and CD3(-)CD16(dim) subsets. Contrary to CD158a and CD158b killer immunoglobulin-like receptors (KIRs), there is a significant positive correlation of NKG2D and CD161 expression with NK cytotoxicity. We show the kinetics of change in CD3(-)CD16(+)NK/K562 conjugate composition, together with the stronger target binding capacity of CD16(bright) NK cells. Furthermore, we show that after coculture of PBLs with K562 the expression of CD107a, a degranulation marker, on CD3(-)CD16(+)NK cells and subsets is time dependent and significantly higher on the cytotoxic CD3(-)CD16(bright) NK subset. The novel data obtained regarding expression of NK cell activating and inhibitory receptors for healthy individuals may aid in detecting changes that are associated with various diseases.

Abstract
The aim of the present study was to analyze whether leukocyte subsets in peripheral blood and tumour biopsies obtained before treatment were able to predict response or survival in patients with metastatic melanoma following Interleukin-2 (IL-2) based immunotherapy. Flow cytometry was performed on peripheral blood for CD4(+) T cells, CD8(+) T cells and CD56(+) natural killer (NK) cells. Immunohistochemical analyses were used to identify CD4(+) T cells, CD8(+) T cells, CD57(+) NK cells and CD64(+) (macrophages) cells in tumour biopsies. High numbers of tumour-associated CD64(+) macrophages in tumour biopsies were statistically significantly associated with poor response to treatment. Our data suggest that tumour-associated macrophages may correlate negatively with response, which may be of biological importance for IL-2 based immunotherapy of malignant melanoma.

Abstract
Signal transducers and activators of transcription (STAT) proteins are a 7-member family of cytoplasmic transcription factors that participate in signal transduction by cytokines, hormones, and growth factors. STAT proteins control the most important cellular processes, including survival, proliferation and differentiation. A great number of cytokines and other factors in different cell types activate STAT1, STAT3 and STAT5 and in this manner regulate processes such as cellular proliferation, differentiation and survival. STATs such as STAT4 and STAT6 have a more specific effect and are engaged in the differentiation of T helper cell populations. Given the critical roles of STAT proteins it has been established in many studies that STAT3 and STAT5 are oncogenes that can contribute to cellular transformation by increasing proliferation and slowing-down apoptosis. On the other hand, STAT1 is a tumour suppressor gene and its inactivation contributes to malignant transformation. Initially STAT proteins were extensively studied in leukaemias, but later their role in the development of different solid tumours has been also shown. Aside from their role in the development of tumours, STAT1, STAT3 and STAT5 can be considered as molecular markers for early detection of certain types of tumours, as well as prognostic factors in the determination of tumour aggressiveness and predictors of response to various types of therapy. Evidence of the deregulation of STAT signalling pathway can serve as a basis for designing novel targeted molecular therapeutic strategies that carry a great potential in the therapy of solid tumours and leukaemias.

Abstract
BACKGROUND Patients with metastatic skin disease in malignant melanoma are difficult to treat, with unresectable lesions proving the biggest challenge. We have recently published data showing a significant clinical response in patients with multiple in-transit melanoma metastases treated with a combination of topical imiquimod and intralesional interleukin (IL)-2. Here we report the results of immunological analysis with the aim of highlighting correlations with our clinical findings. OBJECTIVES To investigate the systemic effects of our localized combination treatment in patients with accessible metastases of melanoma, and to correlate this with their clinical responses. METHODS The peripheral blood mononuclear cells of patients were collected at various time points throughout the treatment. Using antibodies to T-cell subsets we measured the changes in cell populations, and along with polyclonal stimulation, changes in cytokine production from these cells over a treatment course. RESULTS We report an increase in the mean CD4/CD8 ratio from 2.78 to 3.54 with treatment (P < 0.01), and a rise in the percentage of CD25+ cells in the CD4+ population from 14.52% to 38.56%. Furthermore, staining with activation and T-regulatory markers showed that the majority of this population is activated T cells. Cytokine analysis on polyclonally stimulated peripheral blood mononuclear cells showed an increase in the ability of cells to produce interferon (IFN)-gamma over the treatment course, with an initial rise in the IFN-gamma/IL-5 ratio in five of six patients. CONCLUSIONS The results of this study provide evidence that, in the majority of patients with in-transit metastases of melanoma, therapy with a combination of topical imiquimod and intralesional IL-2 induces a systemic immunological effect by reversing some of changes noted in patients with malignant disease.

Abstract
Natural killer cells, as an important subpopulation of cells of the innate immune system have an essential role in defense of the rise and spread of malignancy. These cells have a CD3-CD16 + CD56+ phenotype and they are functionally defined by their ability to lyses tumor cells. We here show that decrease of NK cell activity was significantly associated with advanced clinical stage, increased lactate dehydrogenase (LDH), percentage infiltration of bone marrow with plasma cells, and beta-2 microglobulin. The patients with higher NK cell activity at presentation after receiving VAD protocol have better cumulative survival in comparison with those with low NK cell activity.

Abstract
Natural killer (NK) cells are characterized by a CD3-CD16+ CD56+ immunophenotype and have a central role in the innate immune system. They are defined by their capacity to kill certain tumor-target cells or virus infected cells without prior sensitization or MHC-restriction. The activity of the NK cells is determined by the balance between activation and inhibitory receptor molecules expressed on the surface of NK cells. However, several cytokines and chemokines can significantly modulate their activity, inducing increase of NK cell activity. Immunomodulation mediated by NK cells is very important mechanism in tumor immunity, as well as in other immunodepressions of the immune system. In this study, we summarize the role of several cytokines, including IFN, IL-1, IL-2, IL-4, IL-7, IL-12 and IL-17, on NK cell function. The NK cells, after activation, depending on cytokine environment, can differentiate into NK1 cells that produce Th1 cytokine type (IFN-?, IL-2, IL-12) or NK2 cells that produce Th2 type cytokines, enhance exocytosis and release of previously formed molecules from NK cells (granzyme, perforin). We also describe that the release of cytokines and mediators show local or distance effects, or induce apoptosis (mostly by secreted TNF-?) after binding appropriated killer cell receptors from TNF receptor superfamily.

Abstract
BACKGROUND The few chemoimmunotherapy trials that together with dacarbazine (DTIC) and interferon-alpha 2a (IFNalpha), include retinoic acid (RA), did not include detailed immunological evaluation of functional and phenotypic natural killer (NK) cell characteristics, and have shown contradictory clinical results. MATERIALS AND METHODS Malignant melanoma (MM) patients undergoing phase II-randomized chemoimmunotherapy trials were treated with DTIC, IFNalpha (Hoffmann-La Roche) (group A, n = 31), and with DTIC, IFNalpha and 13-cis-RA (Isotretinoin, Hoffmann-La Roche, Basel, Switzerland) (group B, n = 29). Patients and 42 healthy controls were evaluated by FACS flow analyses for CD3/CD56/CD69 positive cells, NK cytotoxicity in fresh peripheral blood lymphocytes (PBL) and for interferon regulatory factor-1 mRNA expression by reverse transcriptase polymerase chain reaction in treated PBL. RESULTS The addition of RA to a DTIC-IFN regime did not bring any therapeutical benefit in terms of response or survival. Immunological follow-up on days 1, 6 and 27 of each therapy cycle shows a significant increase in NK cell activity in both groups, only on day 6 of the first cycle, while CD69+CD56+ expression increased significantly on day 6 of each therapy cycle, in both groups. Evaluation of the dynamics of expression of IRF-1 of in vitro treated PBL, shows its strong and prompt up-regulation by IFNalpha and synergistic effect of IFNalpha and RA combination. CONCLUSION The dynamics of the increase in CD69 early activation antigen expression on CD56+ NK cells is systematic and serial with the increase being significantly higher on day six of the first cycle in group B patients with clinical response, compared to those without, indicating possible predictive value of CD69 expression for clinical response to chemoimmunotherapy.

Abstract
Natural killer (NK) cells play a role in the innate and adaptive antitumor immune responses. The activity of NK cells is regulated by functionally opposing, activating and inhibitory receptors whose balance ultimately determines whether target cells will be susceptible to NK cell mediated lysis. As melanoma is an immunogenic tumor, the effect of immunomodulating agents is consistently investigated. In this study in 79 metastatic melanoma (MM) patients and 52 controls NK activity, expression of activating NKG2D and CD161 receptors and KIR receptors, CD158a and CD158b, on freshly isolated PBL and NK cells were evaluated. Native NK cell activity of melanoma patients in clinical stage I-III and MM patients was determined against NK sensitive K562, NK resistant Daudi, human melanoma FemX, HeLa and HL 60 target tumor cell lines. In addition, predictive pretherapy immunomodulating effect after 18 h in vitro treatments of PBL of MM patients with rh IL-2, IFN-alpha (IFN), 13-cis retinoic acid (RA) and combination IFN-alpha and RA was evaluated with respect to NK cell lyses against K562 and FemX cell lines. In this study we show for the first time that low expression of CD161 and activating NKG2D receptors, without increased expression of KIR receptors CD158a and CD158b, as well as a decrease in the cytotoxic, CD16(bright) NK cell subset, is associated with a significant impairment in NK cell activity in MM patients. Furthermore, the predictive pretherapy finding that IL-2, IFN, IFN and RA, unlike RA alone, can enhance NK cell activity of MM patients against FemX melanoma tumor cell line can be of help in the design and development of therapeutic regimens, considering that it has recently been shown that low-dose combination of different immunomodulators represents the most promising approach in the therapy of MM.

Abstract
AIM: To induce efficient expansion of natural killer (NK) cells from peripheral blood mononuclear cells (PBMCs) using a culture of anchorage-dependent Wilms tumor cell lines, and to provide a reliable supply for adoptive immunotherapy of hepatocellular carcinoma.
METHODS: Culture expansion of NK cells was achieved using PBMCs cultured with Wilms tumor cells. Cytotoxicity was measured using a standard 51Cr release assay and crystal violet staining technique. The proportions of CD3+, CD4+, CD8+, CD16+, and CD56+ cells were determined by flow cytometry.
RESULTS: After PBMCs from healthy donors and hepatocellular carcinoma (HCC) were cultured with irradiated HFWT cells for 10-21 d, CD56+CD16+ cells shared more than 50% of the cell population, and more than 80% of fresh HFWT cells were killed at an effector/target ratio of 2 over 24 h. NK-enriched lymphocyte population from HCC patients killed HCC-1 and 2 cells with sensitivities comparable to fresh TKB-17RGB cells. HCC cells proliferated 196-fold with the irradiated HFWT cells at 18 d. Stimulation by HFWT cells required intimate cell-cell interaction with PBMC. However, neither the soluble factors released from HFWT cells nor the fixed HFWT cells were effective for NK expansion. The lymphocytes expanded with IL-2 killed fresh HFWT target cells more effectively than the lymphocytes expanded with the 4-cytokine cocktail (IL-l β, IL-2, IL-4 and IL-6). IL-2 was the sole cytokine required for NK expansion.
CONCLUSION: Wilms tumor is sensitive to human NK cells and is highly efficient for selective expansion of NK cells from PBMCs.
