Abstract
NK (Natural killer) cells are a special population of peripheral blood lymphocytes that kill virus-infected cells as well as tumor cells. For testing NK cell function, the classic gold standard assay has been used for a long time, determining the activity from target tumor cells using radioactive chromium in cell cultures for 4h. In this study two hematological cell lines K562 and MDS where used and target and results showed different sensitivity to killing by NK cells separated from healthy volunteers. Results have been shown that MDS release significantly more radioactive chromium indicating higher degree of necrosis during cell culture. In addition, K562 cell line is better target for NK killing in all different E:T ratio in comparison to MDS cell line previously described. Based on this, it is suggested that K562 cells be continues used in the future as better target for investigation NK killing.

Sharma M, Niu L, Zhang X, Huang S. Comparative transcriptomes reveal pro-survival and cytotoxic programs of mucosal-associated invariant T cells upon Bacillus Calmette-Guérin stimulation. Front Cell Infect Microbiol 2023; 13:1134119. [PMID: 37091679 PMCID: PMC10116416 DOI: 10.3389/fcimb.2023.1134119] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 03/15/2023] [Indexed: 04/08/2023] Open
Abstract
Mucosal-associated invariant T (MAIT) cells are protective against tuberculous and non-tuberculous mycobacterial infections with poorly understood mechanisms. Despite an innate-like nature, MAIT cell responses remain heterogeneous in bacterial infections. To comprehensively characterize MAIT activation programs responding to different bacteria, we stimulated MAIT cells with E. coli to compare with Bacillus Calmette-Guérin (BCG), which remains the only licensed vaccine and a feasible tool for investigating anti-mycobacterial immunity in humans. Upon sequencing mRNA from the activated and inactivated CD8+ MAIT cells, results demonstrated the altered MAIT cell gene profiles by each bacterium with upregulated expression of activation markers, transcription factors, cytokines, and cytolytic mediators crucial in anti-mycobacterial responses. Compared with E. coli, BCG altered more MAIT cell genes to enhance cell survival and cytolysis. Flow cytometry analyses similarly displayed a more upregulated protein expression of B-cell lymphoma 2 and T-box transcription factor Eomesodermin in BCG compared to E.coli stimulations. Thus, the transcriptomic program and protein expression of MAIT cells together displayed enhanced pro-survival and cytotoxic programs in response to BCG stimulation, supporting BCG induces cell-mediated effector responses of MAIT cells to fight mycobacterial infections.

Abstract
This study explored the correlation between peripheral blood CD3+, CD3+/CD4+, CD3+/CD8+, CD4+/CD8+, CD3-/CD16+ CD56+, and CD3-CD19+ and disease activity of different subtypes of systemic lupus erythematosus (SLE). The percentages of CD3+, CD3+/CD4+, CD3+/CD8+, CD4+/CD8+, CD3-/CD16+ CD56+, and CD3-CD19+ in the peripheral blood of patients (n = 80) classified into lupus nephritis, blood involvement, and joint involvement and SLE in different active stages were detected by flow cytometry. Their correlations with baseline clinical experimental indicators of SLE patients' SLE disease activity index score (SLEDAI) and complement C3 were analyzed. The results showed that CD3+, CD3+/CD4+, and CD3+/CD8+ at baseline level were negatively correlated with SLEDAI scores. These were positively correlated with C3. In conclusion, T-lymphocyte subpopulations are closely related to SLE activity and can be used as reference indicators to evaluate the SLE activity.

Abstract
This study aimed to investigate the proportion of surface activation markers on natural killer (NK) cells in children with infectious mononucleosis (IM) and to explore its clinical relevance. A total of 17 children hospitalized with IM were included in this study as the experimental group. Meanwhile, healthy children matched for age and gender served as controls. First, we isolated peripheral blood mononuclear cells from children with IM and healthy children. Then, NK cell surface markers were stained with monoclonal antibodies and analyzed by flow cytometry. The results showed that the percentage of CD3- CD16+ NK cells was higher in peripheral blood lymphocytes from children with IM than that from healthy children (t = -4.52, P < 0.05). And the expression of the surface activation markers CD69 and CD25 on CD3- CD16+ NK cells was also higher in children with IM (t = -7.729, P < 0.05; t = -5.068, P < 0.05). There was a positive correlation between the percentage of CD3- CD16+ NK cells in peripheral blood and the duration of fever in children with IM (r = 0.530, P < 0.05). Therefore, the proportion of NK cell subsets in children's peripheral blood changes in the acute phase of IM, suggesting that NK cells enhance their cytotoxicity and play a role in the control of infection in children with IM. Higher levels of CD3- CD16+ NK cells and the association with disease progression suggest that these cells might be a useful index to help evaluate the disease course.

Abstract
The Atlantic cod’s unusual immune system, entirely lacking the Major Histocompatibility class II pathway, has prompted intriguing questions about what mechanisms are used to combat bacterial infections and how immunological memory is generated. By single-cell RNA sequencing we here report an in-depth characterisation of cell types found in immune tissues, the spleen and peripheral blood leukocytes of Atlantic cod. Unbiased transcriptional clustering revealed eleven distinct immune cell signatures. Resolution at the single cell level enabled characterisation of the major cell subsets including the cytotoxic T cells, B cells, erythrocytes, thrombocytes, neutrophils, and macrophages. Additionally, to our knowledge we are the first to uncover cell subsets in Atlantic cod which may represent dendritic cells, natural killer-like cells, and a population of cytotoxic cells expressing GATA-3, a master transcription factor of T helper 2 cells. We further identify putative gene markers for each cluster and describe the relative proportions of each cell type in the spleen and peripheral blood leukocytes. Of the major haematopoietic cell populations, the lymphocytes make up 55 and 68% of the spleen and peripheral blood leukocytes respectively, while the myeloid cells make up 45 and 32%. By single-cell analysis, this study provides the most detailed molecular and cellular characterisation of the immune system of the Atlantic cod so far.

Concordance between peripheral and decidual NK cell subsets and killer immunoglobulin-like receptors in women with recurrent spontaneous miscarriages. J Reprod Immunol 2020; 140:103130. [PMID: 32330774 DOI: 10.1016/j.jri.2020.103130] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 03/02/2020] [Accepted: 04/04/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND The role of decidual natural killer (dNK) cells in normal and complicated pregnancy and their relation with peripheral NK (pNK) cells remains unclear. The study aim was phenotypic analysis of pNK and dNK cells at time of miscarriage in recurrent spontaneous miscarriage (RSM) patients to assess whether measuring levels of pNK cell populations can reflect changes in dNK cells or not. METHODS This study included 40 middle aged pregnant women in the 1st trimester subjected to evacuation because of a current miscarriage. They had a history of previous ≥ two unexplained miscarriages. Frequencies of pNK and dNK cells, based on the expression of CD56, CD16, inhibitory (CD158b) and activating (CD161) Killer immunoglobulin-like receptors (KIRs), were detected by flow cytometry. RESULTS Percentages of CD56+ NK cells in peripheral blood and decidua were 17.5 % and 17.3 %, respectively. In both blood and decidua, CD56dim NK cells were exceeding CD56bright NK cells. The CD56dim CD16- NK cells were the predominating subset of NK cells, followed by CD56dim CD16dim. No substantial differences were detected in the levels of KIRs expression by the different NK subsets between blood and decidua. Abnormal up-regulation of both CD161 and CD158b on NK cells was observed in blood and decidua. CONCLUSION At the time of miscarriage, patients with RSM have an extremely active immune system and an increased number of toxic NK cells both in blood and decidua. The pNK cells reflect dNK cell changes during miscarriage and may be a useful non-invasive predicting tool in reproductive failure setting.

Abstract
Regional lymph nodes (LN)s represent important immunological barriers in spreading of malignant tumors. However, they are the most frequent early metastatic site in melanoma. Immunomodulatory agents including cytokines have been included in therapy of melanoma and have shown severe side effects and toxicity. In this sense, there is a growing need for bringing these agents to further in vitro testing that may enlighten aspects of their regional application. Therefore, the aim of this study was to investigate the effect of interleukin (IL)-2 and IL-15, the two cytokines with similar immune-enhancing effects, on the expression of activating NKG2D, inhibitory CD158a and CD158b receptors on CD8+ T, NKT-like and NK cell lymphocyte subsets from regional LNs of melanoma patients. In this study, we showed significant effects of IL-2 and IL-15 cytokine treatments on the expression of activating NKG2D and on inhibitory CD158a and CD158b receptors on lymphocytes, CD8+ T, NKT-like and NK cell lymphocyte subsets originating from regional LNs of melanoma patients. Furthermore, IL-2 and IL-15 by inducing the expression of NKG2D activating receptor on innate and on adaptive lymphocyte subsets and by augmenting NK cell antitumor cytotoxicity that correlated with the cytokine-induced NKG2D expression, increased antitumor potential of immune cells in regional LNs of melanoma patients irrespective of LN involvement. These findings indicate the importance of immune cell population from regional LNs of melanoma patients in the development of immune intervention strategies that may if applied locally increase antitumor potential to the level that controls tumor progressions.

Abstract
CD161 is a C-type lectin-like receptor expressed on the majority of natural killer (NK) cells; however, the significance of CD161 expression on NK cells has not been comprehensively investigated. Recently, we found that CD161 expression identifies a transcriptional and innate functional phenotype that is shared across various T cell populations. Using mass cytometry and microarray experiments, we demonstrate that this functional phenotype extends to NK cells. CD161 marks NK cells that have retained the ability to respond to innate cytokines during their differentiation, and is lost upon cytomegalovirus-induced maturation in both healthy and human immunodeficiency virus (HIV)-infected patients. These pro-inflammatory NK cells are present in the inflamed lamina propria where they are enriched for integrin CD103 expression. Thus, CD161 expression identifies NK cells that may contribute to inflammatory disease pathogenesis and correlates with an innate responsiveness to cytokines in both T and NK cells.

Abstract
Background: The aberrant expression of surface receptors on immunocytes may represent potential markers of tumor escape for nasopharyngeal carcinoma (NPC). The aim of this study was to investigate the expression of representative receptors on natural killer (NK) cells and NK group 2, member D (NKG2D) on immunocytes in the peripheral blood of patients with NPC. Methods: Patients (n = 64) with NPC prior to initiation of treatment were defined as the study group. Healthy volunteers (n = 31) served as the control group. The expression of NK cells and NKT cells; the triggering receptors NKp30, NKp44, and NKp46 on NK cells; the activating receptor NKG2D on NK cells, CD4+ T cells, and CD8+ T cells; and the inhibitory receptors CD158b and CD159a on NK cells were analyzed by flow cytometry in the two groups. Results: Here, our study showed that no differences were observed in terms of the numbers of NK cells or NKT cells, or the expression of CD158b and CD159a on the surface of NK cells between the two groups. Nevertheless, the expression levels of NKp30 and NKp46 on NK cells in the NPC patients were significantly lower than in the healthy individuals (P < 0.05). No differences existed in the expression of NKG2D on NK cells, but NKG2D on CD8+ T cells showed a markedly lower expression in the study group (P < 0.001). Conclusions: Our findings may reflect a possible mechanism of immune evasion for NPC. The enhancement of immunotherapy concerning NKp30, NKp46, and NKG2D may be an innovative treatment strategy for patients with NPC.

Abstract
Cell-based adoptive immunotherapy for the treatment of various cancer types has attracted the attention of scientists. However, due to the absence of unitary standard protocols to produce large quantities of clinical-grade effector cells, it remains challenging to translate the experimental findings into clinical applications. The present study used methods complying with good manufacturing practice to induce effector cells from human peripheral blood mononuclear cells (PBMCs) of healthy donors by interleukin-2 and anti-Her-2 antibody with or without anti-CD3 antibodies (OKT3). The results indicated that the addition of OKT3 resulted in a greater expansion of the total cells and CD8+ T cells, and primarily induced the PBMCs to differentiate into CD3+ T cells. Regardless of the presence of OKT3, the expression of activating receptor of natural killer (NK) group 2, member D, and the inhibitory receptors of CD158a and CD158b on NK cells and NKT cells was increased, while the expression of NKp46 was inhibited on NK cells, but not on NKT cells. Furthermore, OKT3 did not affect the toxicity of the effector cells. Subgroup analysis indicated that although a variation of the composition of effector cells was present in different individuals under identical culture conditions, consistent marker expression on effector cells and target cell-killing effects were observed in different subgroups treated with or without OKT3. Furthermore, western blot analysis indicated that OKT3, apart from its involvement in cell cycle regulation, affects transcription and protein translation during processes of proliferation and differentiation. The present study provided experimental data regarding the production of effector cells for adoptive immunotherapy as a clinical application.

Abstract
AIM As innate immune cells natural killer (NK), NK-like T and CTLγδ are important in antitumour response in multiple myeloma (MM), the aim of this study was to investigate some functional and phenotypical characteristics of these cells in MM. METHODS 29 patients with MM prior to therapy, in clinical stage I-III and 15 healthy controls (HCs) were investigated. Percent of immune cells in peripheral blood, NK cell activity, expression of activating (CD161) and inhibitory (CD158a, CD158b) NK cell receptors on CD3-CD16+ NK cells were evaluated using 51-chromium-release assay and by flow cytometry. Production of interleukin (IL) 2 and tumour necrosis factor (TNF)α was analysed in supernatants from in vitro activated peripheral blood mononuclear cells. RESULTS In patients with MM the percent of NK cells and their two subsets did not differ from controls, while NK-like T and CTLγδ cells were significantly decreased. Significant impairment of NK cell cytotoxicity, CD107a expression and interferon γ intracellular level was also shown. There was a significant decrease in CD161 and an increase in CD158a receptor expression on NK cells in these patients. Also IL-2 production was lowest in clinical stage III. However, TNF-α production did not differ between patients and HCs. CONCLUSIONS Altered expression of CD161 activating and CD158a KIR inhibitory receptor is responsible for impaired antitumour activity of NK cells in MM patients. These new biomarkers may be helpful for patient selection for immunotherapy with cytokines, and novel KIR blocking monoclonal antibodies that enhance NK cell antimyeloma activity and provide clinical benefit.

Abstract
Vitamin D has a pivotal role in regulating immune responses by promoting Th2 immune responses and suppressing Th1 responses. Propensities to a Th1 immune response and increased NK-cell levels and cytotoxicity have been reported in women with recurrent pregnancy losses (RPL). In women with RPL, vitamin D deficiency is prevalent; however, the effect of vitamin D on NK cells is largely unknown. In this study, we demonstrated that CD69(+) activating receptor expression on NK cells was significantly decreased by incubation with 1,25(OH)2 D3 in a dose-dependent manner, while CD158a and CD158b inhibitory receptor expression was upregulated. The degranulation marker CD107a was significantly downregulated on NK cells following incubation with 1,25(OH)2 D3 . NK-cell conjugation with K562 target cells was not affected by 1,25(OH)2 D3 ; however, depolarization of perforin granules in conjugated NK cells was significantly increased. TLR4 expression on NK cells was significantly decreased and TNF-α and IFN-γ production was significantly reduced by 1,25(OH)2 D3 through interference with NF-κB. Our results suggest 1,25(OH)2 D3 has immune regulatory effects on NK cell cytotoxicity, cytokine secretion and degranulation process as well as TLR4 expression. Potential therapeutic application of 1,25(OH)2 D3 for dysregulated NK-cell immunity should be explored in the future.

Abstract
In this study, we sought to understand the selective pressures shaping the Ig-producing cell repertoire in the parotid glands of primary Sjögren's syndrome (pSS) patients before and after rituximab treatment (RTX). In particular, we evaluated the role of potential N-glycosylation motifs acquired by somatic hypermutation (ac-Nglycs) within Ig H chain V region (IGHV) genes as alternative selective pressures for B cells in pSS. Five pSS patients received RTX. Sequential parotid salivary gland biopsies were taken before RTX, at 12 wk and at 36-52 wk after treatment. Parotid biopsies from four non-pSS patients served as controls. Sequence analysis was carried out on the IgA and IgG RNA transcripts expressing IGHV3 genes in all parotid biopsies. Both IgG and IgA sequences from pSS patients exhibited no evidence for positive Ag-driven selection pressure in their CDRs in contrast to non-pSS controls. The prevalence of IgG sequences with ac-Nglycs was significantly higher in pSS patients than in non-pSS controls. Selection pressures shaping the IgG and IgA repertoire within pSS patients' parotid glands are distinct from those in non-pSS controls, with very little evidence for positive (auto)antigen selection. The higher prevalence of ac-Nglycs on pSS-IgG compared with non-pSS IgG indicates that ac-Nglycs could be an alternative form of selection pressure. We speculate that B cell hyperproliferation within parotid glands of pSS patients may result from Ag-independent interactions such as that between glycosylated B cell receptors and lectins within the microenvironment rather than (auto)antigen-specific stimulation. Our study brings a new perspective into research on pSS.

Abstract
The present study compares the profile of NK cells in an in vitro re-exposure by Vaccinia virus (VACV), in groups that have had a previous vaccination or natural infection. Our data suggests that stimulation with VACV triggers a cytotoxic response by NK cells marked by an increase of NCRs: NKp30, NKp44, and NKp46 in infected (vaccinated and unvaccinated) subjects and in non-infected vaccinated patients, when compared with non-infected unvaccinated individuals. However, the degranulation and secretion processes are inhibited in infected (vaccinated and unvaccinated) subjects and in the non-infected vaccinated patients, when compared with non-infected unvaccinated individuals. We demonstrated that stimulation with VACV downregulates the percentage of expression of Perforin, Granzyme A, and CD107a, but upregulate CD94 in infected (vaccinated and unvaccinated) subjects and in non-infected vaccinated patients, when compared with non-infected unvaccinated individuals. Furthermore, the percentage of IFN-γ(+) NK cells was significantly lower in non-infected unvaccinated subjects, when compared with infected (vaccinated and unvaccinated) and non-infected vaccinated individuals. Our results also show that the percentage of TNF-α(+) NK cells was significantly higher in infected (vaccinated and unvaccinated) subjects and in non-infected vaccinated patients, when compared with non-infected unvaccinated individuals, after in vitro stimulation with UV-inactivated VACV. Our data suggest that the expression of NCRs NKp30, NKp44, NKp46 and cytokines by NK cells are important in the innate response against VACV.

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
Human immunodeficiency virus (HIV)-1 infection compromises the natural killer (NK) cell function and leads to defective control on virus multiplication. One of the major features of HIV-1 infection is the expansion of a functionally compromised defective NK cell subset (CD56(-)CD16(+)). We analyzed the NK cell subsets in early HIV infection to determine the effect of NK cell perturbation on the viral load set point, a marker of disease progression. We report that the defective NK cells are expanded in early HIV infection within 6-8 months of acquiring infection and are correlated with a higher plasma viral load set point, suggesting its utility as a predictive marker for disease progression. The expression of CD161, a molecular marker responsible for proliferation and differentiation of NK cells, was significantly down-regulated in the defective NK cells as compared to slow progressors (p=0.0009) and healthy controls (p=0.0003) and was correlated with a higher viral load set point in early HIV-1 infection (r=-0.6154, p=0.03), suggesting the probable role of CD161 expression in the impaired proliferation and differentiation of defective NK cells into the functional NK cells in early HIV infection. The reduction in CD161 expression on the defective NK cells in early HIV infection is thus indicative of the role of innate immune cells in early control of HIV infection.

Abstract
As IL-2 and IFN-α modulate NK cell activity it was of interest to investigate the expression of newly defined NK cell receptors and augmented NK cell activity in healthy individuals after cytokine in vitro treatment. Peripheral blood lymphocytes (PBL) obtained from 31 healthy volunteers treated for 18 h with 200 IU/ml IL-2 and 250 IU/ml IFN-α were evaluated for NK cell cytotoxicity. Expression of NKG2D, CD161, CD158a, CD158b receptors was analyzed on CD3⁻CD16+ NK cells, cytotoxic CD16(bright) and regulatory CD16(dim) subsets by FACS flow. The found induced significant in vitro enhancement of NK cell activity by both cytokines is supported by specific cytokine induction in PBL of pSTAT1 and pSTAT5, determined by Western blotting, as well as induction of IRF-1 transcription. Both cytokines induce significant up-regulation of NKG2D expression while only IFN-α induced significant up-regulation of CD161, with no alteration in KIR expression by either cytokine on CD3⁻CD16+ NK cells. Investigated cytokines did not induce change in NK cell bright and dim subset distribution. Moreover, we find that, not only cytokine receptor induction on the CD3⁻CD16+ NK cells, but also simultaneous increase in their percentage and/or density on CD16(bright) and CD16(dim) subsets, represent good indicators of receptor cytokine-susceptibility. As the role of NK cells has been shown in the loss of tolerance, infection and cancer, the data obtained in this study may be of help in NK cell profiling, by giving referent values of cytokine-induced novel NK cell receptor expression either in evaluation of these diseases or in immunomonitoring during cytokine immunotherapy.

Abstract
In a previous report, we showed that the in vivo cytotoxic activity of the natural killer (NK) cells isolated from resveratrol-pretreated rats is significantly enhanced compared with that of the non-pretreated rats; however, the underlying mechanism remains unclear. In the present study, we use cultured NK92 cell line to examine the possible signaling pathways underlying the resveratrol-induced activation. Using cultured K562, HepG2, and A549 cells as targets, we show that resveratrol pretreatment increases NK cell cytotoxicity in a dose-dependent manner. The enhanced cytotoxic effect is accompanied by increases in JNK and ERK-1/2 MAP kinase activity and perforin expression. Moreover, the expression of NKG2D, an upstream signaling molecule of the MAP kinases pathway, is also enhanced. Resveratrol-enhanced perforin expression and cytotoxic activity are effectively inhibited by pretreatment with the inhibitors of JNK (SP600125), ERK-1/2 (PD98059), or by siRNAs against JNK-1 and ERK-2. However, the inhibitors or siRNA to p38 exhibits no effect. Since IL-2 has been shown to induce NKG2D expression and perforin release, we therefore, examined whether IL-2 and resveratrol act in parallel. We show that IL-2 also stimulates perforin expression, however, when treated together with resveratrol, they exhibit no additive effect. The results suggest that in NK92 cells, resveratrol may act via a similar or overlapping pathway as that of IL-2, to enhance perforin expression and cytotoxic activity. Data presented strongly indicate that resveratrol act via NKG2D-dependent JNK and ERK-1/2 pathways.
