Substances that are recognized by the immune system and induce an immune reaction.
Differentiation antigens residing on mammalian leukocytes. CD stands for cluster of differentiation, which refers to groups of monoclonal antibodies that show similar reactivity with certain subpopulations of antigens of a particular lineage or differentiation stage. The subpopulations of antigens are also known by the same CD designation.

The CD3 complex includes the gamma, delta, epsilon, zeta, and eta chains (subunits). When antigen binds to the T-cell receptor, the CD3 complex transduces the activating signals to the cytoplasm of the T-cell. The CD3 gamma and delta chains (subunits) are separate from and not related to the gamma/delta chains of the T-cell receptor (RECEPTORS, ANTIGEN, T-CELL, GAMMA-DELTA).

A member of the tumor necrosis factor receptor superfamily with specificity for CD40 LIGAND. It is found on mature B-LYMPHOCYTES and some EPITHELIAL CELLS, lymphoid DENDRITIC CELLS. Evidence suggests that CD40-dependent activation of B-cells is important for generation of memory B-cells within the germinal centers. Mutations of the gene for CD40 antigen result in HYPER-IGM IMMUNODEFICIENCY SYNDROME, TYPE 3. Signaling of the receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS.

Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
A costimulatory ligand expressed by ANTIGEN-PRESENTING CELLS that binds to CD28 ANTIGEN with high specificity and to CTLA-4 ANTIGEN with low specificity.

The antigens are found on B-lymphocytes, macrophages, epidermal cells, and sperm and are thought to mediate the competence of and cellular cooperation in the immune response. The term IA antigens used to refer only to the proteins encoded by the IA genes in the mouse, but is now used as a generic term for any class II histocompatibility antigen.

Histocompatibility Antigens Class I
Membrane glycoproteins consisting of an alpha subunit and a BETA 2-MICROGLOBULIN beta subunit. In humans, highly polymorphic genes on CHROMOSOME 6 encode the alpha subunits of class I antigens and play an important role in determining the serological specificity of the surface antigen. Class I antigens are found on most nucleated cells and are generally detected by their reactivity with alloantisera. These antigens are recognized during GRAFT REJECTION and restrict cell-mediated lysis of virus-infected cells.
A member of the tumor necrosis factor receptor superfamily that is specific for 4-1BB LIGAND. It is found in a variety of immune cell types including activated T-LYMPHOCYTES; NATURAL KILLER CELLS; and DENDRITIC CELLS.

They are found throughout the lymphatic system, and in non-lymphoid tissues such as SKIN and the epithelia of the intestinal, respiratory, and reproductive tracts. They trap and process ANTIGENS, and present them to T-CELLS, thereby stimulating CELL-MEDIATED IMMUNITY. They are different from the non-hematopoietic FOLLICULAR DENDRITIC CELLS, which have a similar morphology and immune system function, but with respect to humoral immunity (ANTIBODY PRODUCTION).
Receptors present on activated T-LYMPHOCYTES and B-LYMPHOCYTES that are specific for INTERLEUKIN-2 and play an important role in LYMPHOCYTE ACTIVATION.

The tissue is then examined by fluorescence microscopy.
Human immune-response or Class II antigens found mainly, but not exclusively, on B-lymphocytes and produced from genes of the HLA-D locus. They are extremely polymorphic families of glycopeptides, each consisting of two chains, alpha and beta. This group of antigens includes the -DR, -DQ and -DP designations, of which HLA-DR is most studied; some of these glycoproteins are associated with certain diseases, possibly of immune etiology.
A form of undifferentiated malignant LYMPHOMA usually found in central Africa, but also reported in other parts of the world. It is commonly manifested as a large osteolytic lesion in the jaw or as an abdominal mass. B-cell antigens are expressed on the immature cells that make up the tumor in virtually all cases of Burkitt lymphoma. The Epstein-Barr virus (HERPESVIRUS 4, HUMAN) has been isolated from Burkitt lymphoma cases in Africa and it is implicated as the causative agent in these cases; however, most non-African cases are EBV-negative.
Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

(from The Dictionary of Cell Biology, Lackie and Dow, 3rd ed.)
Mice homozygous for the mutant autosomal recessive gene "scid" which is located on the centromeric end of chromosome 16. These mice lack mature, functional lymphocytes and are thus highly susceptible to lethal opportunistic infections if not chronically treated with antibiotics. The lack of B- and T-cell immunity resembles severe combined immunodeficiency (SCID) syndrome in human infants. SCID mice are useful as animal models since they are receptive to implantation of a human immune system producing SCID-human (SCID-hu) hematochimeric mice.
Immunized T-lymphocytes which can directly destroy appropriate target cells. These cytotoxic lymphocytes may be generated in vitro in mixed lymphocyte cultures (MLC), in vivo during a graft-versus-host (GVH) reaction, or after immunization with an allograft, tumor cell or virally transformed or chemically modified target cell. The lytic phenomenon is sometimes referred to as cell-mediated lympholysis (CML). These CD8-positive cells are distinct from NATURAL KILLER CELLS and NATURAL KILLER T-CELLS. There are two effector phenotypes: TC1 and TC2.
Recombinant Fusion Proteins
A heterogeneous group of immunocompetent cells that mediate the cellular immune response by processing and presenting antigens to the T-cells. Traditional antigen-presenting cells include MACROPHAGES; DENDRITIC CELLS; LANGERHANS CELLS; and B-LYMPHOCYTES. FOLLICULAR DENDRITIC CELLS are not traditional antigen-presenting cells, but because they hold antigen on their cell surface in the form of IMMUNE COMPLEXES for B-cell recognition they are considered so by some authors.

They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner.
The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc.
A single, unpaired primary lymphoid organ situated in the MEDIASTINUM, extending superiorly into the neck to the lower edge of the THYROID GLAND and inferiorly to the fourth costal cartilage.

The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.
A heterodimeric protein that is a cell surface antigen associated with lymphocyte activation. The initial characterization of this protein revealed one identifiable heavy chain (ANTIGENS, CD98 HEAVY CHAIN) and an indeterminate smaller light chain. It is now known that a variety of light chain subunits (ANTIGENS, CD98 LIGHT CHAINS) can dimerize with the heavy chain. Depending upon its light chain composition a diverse array of functions can be found for this protein. Functions include: type L amino acid transport, type y+L amino acid transport and regulation of cellular fusion.

Immunoglobulins produced in response to VIRAL ANTIGENS.
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Complement Fixation Tests
Serologic tests based on inactivation of complement by the antigen-antibody complex (stage 1). Binding of free complement can be visualized by addition of a second antigen-antibody system such as red cells and appropriate red cell antibody (hemolysin) requiring complement for its completion (stage 2). Failure of the red cells to lyse indicates that a specific antigen-antibody reaction has taken place in stage 1. If red cells lyse, free complement is present indicating no antigen-antibody reaction occurred in stage 1.
Simian virus 40
Substances that augment, stimulate, activate, potentiate, or modulate the immune response at either the cellular or humoral level. The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.
gp100 Melanoma Antigen
Major Histocompatibility Complex
The genetic region which contains the loci of genes which determine the structure of the serologically defined (SD) and lymphocyte-defined (LD) TRANSPLANTATION ANTIGENS, genes which control the structure of the IMMUNE RESPONSE-ASSOCIATED ANTIGENS, HUMAN; the IMMUNE RESPONSE GENES which control the ability of an animal to respond immunologically to antigenic stimuli, and genes which determine the structure and/or level of the first four components of complement.
Killer Cells, Natural
Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.
A technique that combines protein electrophoresis and double immunodiffusion. In this procedure proteins are first separated by gel electrophoresis (usually agarose), then made visible by immunodiffusion of specific antibodies. A distinct elliptical precipitin arc results for each protein detectable by the antisera.
Distinct clinical and laboratory activity of two recombinant interleukin-2 preparations. (1/766)Interleukin-2 (IL-2) is a potent lymphokine that activates natural killer cells, T cells, and other cells of the immune system. Several distinct recombinant human IL-2 preparations have shown antitumor activity, particularly for renal cell cancer and melanoma. Somewhat distinct immune and clinical effects have been noted when different IL-2 preparations have been tested clinically; however, the regimens and doses used were not identical. To compare these more directly, we have evaluated two clinical recombinant IL-2 preparations in vitro and in vivo using similar regimens and similar IUs of IL-2. We used the Food and Drug Administration-approved, commercially available Chiron IL-2 and the Hoffmann LaRoche (HLR) IL-2 supplied by the National Cancer Institute. Using equivalent IUs of IL-2, we noted quantitative differences in vitro and in vivo in the IL-2 activity of these two preparations. In patients receiving comparable IUs of the two preparations, HLR IL-2 induced the release of more soluble IL-2 receptor alpha into the serum than Chiron IL-2. In addition, more toxicities were noted in patients receiving 1.5 x 10(6) IU of HLR IL-2 than were seen in patients treated with 1.5 x 10(6) or even 4.5 x 10(6) IU of Chiron IL-2. These toxicities included fever, nausea and vomiting, and hepatic toxicity. In vitro proliferative assays using IL-2-dependent human and murine cell lines indicated that the IU of HLR IL-2 was more effective than Chiron IL-2 at inducing tritiated thymidine incorporation. Using flow cytometry, we also found quantitative differences in the ability of these two preparations to bind to IL-2 receptors. These findings indicate that approximately 3-6 IU of Chiron IL-2 are required to induce the same biological effect as 1 IU of HLR IL-2. (+info)
Long-term fetal microchimerism in peripheral blood mononuclear cell subsets in healthy women and women with scleroderma. (2/766)Fetal CD34(+) CD38(+) cells have recently been found to persist in maternal peripheral blood for many years after pregnancy. CD34(+) CD38(+) cells are progenitor cells that can differentiate into mature immune-competent cells. We asked whether long-term fetal microchimerism occurs in T lymphocyte, B lymphocyte, monocyte, and natural-killer cell populations of previously pregnant women. We targeted women with sons and used polymerase chain reaction for a Y-chromosome-specific sequence to test DNA extracted from peripheral blood mononuclear cells (PBMC) and from CD3, CD19, CD14, and CD56/16 sorted subsets. We also asked whether persistent microchimerism might contribute to subsequent autoimmune disease in the mother and included women with the autoimmune disease scleroderma. Scleroderma has a peak incidence in women after childbearing years and has clinical similarities to chronic graft-versus-host disease that occurs after allogeneic hematopoietic stem-cell transplantation, known to involve chimerism. Sixty-eight parous women were studied for male DNA in PBMC and 20 for PBMC subsets. Microchimerism was found in PBMC from 33% (16 of 48) of healthy women and 60% (12 of 20) women with scleroderma, P =.046. Microchimerism was found in some women in CD3, CD19, CD14, and CD56/16 subsets including up to 38 years after pregnancy. Microchimerism in PBMC subsets was not appreciably more frequent in scleroderma patients than in healthy controls. Overall, microchimerism was found in CD3, CD19, and CD14 subsets in approximately one third of women and in CD56/16 in one half of women. HLA typing of mothers and sons indicated that HLA compatibility was not a requirement for persistent microchimerism in PBMC subsets. Fetal microchimerism in the face of HLA disparity implies that specific maternal immunoregulatory pathways exist that permit persistence but prevent effector function of these cells in normal women. Although microchimerism in PBMC was more frequent in women with scleroderma than healthy controls additional studies will be necessary to determine whether microchimerism plays a role in the pathogenesis of this or other autoimmune diseases.

Phenotypic analysis and proliferative responses of human endometrial granulated lymphocytes during the menstrual cycle. (3/766)The in vivo function of the unusual population of CD56+ CD16- endometrial granulated lymphocytes (eGLs) in human endometrium is unknown; their increased numbers in the secretory phase of the menstrual cycle suggests that they may play a role in the immunobiology of nonpregnant endometrium. In the present study, the phenotype and proliferative responses of eGLs at various phases of the menstrual cycle were compared with those in early pregnancy. Endometrial GLs were highly purified (> 98% CD56+) using immunomagnetic separation, and the expression of cell surface antigens was examined in smears using a double immunohistochemical labeling technique. Proliferative responses to mitogens and interleukin 2 (IL-2) were assessed in hanging drops in 60-well Terasaki plates. There was low to no expression of CD3, CD8, CD16, HML-1, L-selectin, and CD25 (IL-2 receptor alpha) on CD56+ cells isolated from nonpregnant and pregnant endometrium. The expression of CD2, CD49a, and CD122 (IL-2 receptor beta, IL-2Rbeta), however, increased from the proliferative to the late secretory phase of the menstrual cycle. In contrast, CD11a, CD69, and CD49d expression was high and did not vary with menstrual cycle phase; CD49d levels were significantly reduced in early pregnancy. Unlike early-pregnancy eGLs, none of the CD56+ eGL cultures throughout the menstrual cycle displayed phytohaemagglutinin (PHA)-induced lymphoproliferation. In contrast, eGLs from nonpregnant endometrium in the presence of 5 or 100 U/ml IL-2 after 48- and 120-h incubation showed significant proliferative responses, as did eGL cultures from early pregnancy. A significantly reduced number of proliferative phase eGL cultures proliferated in response to IL-2 compared to secretory phase and early-pregnancy eGL cultures. The IL-2-induced proliferative responses of CD56+ eGLs were associated with increased IL-2Rbeta (CD122) expression. These findings demonstrate 1) differential eGL expression of CD2, CD49a, and CD122 during the menstrual cycle; 2) differential IL-2-induced eGL proliferative responses during the menstrual cycle; and 3) differences between eGLs from nonpregnant and pregnant endometrium in CD49d expression and their ability to respond to PHA.

Expression of killer inhibitory receptors on cytotoxic cells from HIV-1-infected individuals. (4/766)Dysfunction of cytotoxic activity of T and natural killer (NK) lymphocytes is a main immunological feature in patients with AIDS, but its basis are not well understood. It has been recently described that T and NK cell-mediated cytotoxicity can be regulated by HLA killer inhibitory receptors (KIR). In this work, we have determined on cytotoxic T cells and NK cells from HIV-1-infected individuals the expression of the following KIR molecules: p58, p70, and ILT2 (immunoglobulin-like family KIR) as well as CD94 and NKG2A (C-lectin-type family KIR). With some exceptions, no significant changes were found on the expression of immunoglobulin-like KIR in either CD8+ or CD56+ cells. Interestingly, the percentages of CD8+ and CD56+ cells expressing CD94 were significantly increased in these individuals. We also show that, in vitro, IL-10 up-regulates CD94 expression on CD8+ and CD56+ cells obtained from normal individuals, suggesting that the augmented expression observed in HIV-infected individuals could be related to the high levels of IL-10 previously described in HIV-1-infected individuals.

Differential cytokine and chemokine gene expression by human NK cells following activation with IL-18 or IL-15 in combination with IL-12: implications for the innate immune response. (5/766)NK cells constitutively express monocyte-derived cytokine (monokine) receptors and secrete cytokines and chemokines following monokine stimulation, and are therefore a critical component of the innate immune response to infection. Here we compared the effects of three monokines (IL-18, IL-15, and IL-12) on human NK cell cytokine and chemokine production. IL-18, IL-15, or IL-12 alone did not stimulate significant cytokine or chemokine production in resting NK cells. The combination of IL-18 and IL-12 induced extremely high amounts of IFN-gamma protein (225 +/- 52 ng/ml) and a 1393 +/- 643-fold increase in IFN-gamma gene expression over those in resting NK cells. IL-15 and IL-12 induced less IFN-gamma protein (24 +/- 10 ng/ml; p < 0.007) and only a 45 +/- 19-fold increase in IFN-gamma gene expression over those in resting NK cells. The CD56bright NK cell subset produced significantly more IFN-gamma following IL-18 and IL-12 compared with CD56dim NK cells (p < 0.008). However, the combination of IL-15 and IL-12 was significantly more potent than that of IL-18 and IL-12 for NK cell production of IL-10, macrophage inflammatory protein-1alpha, macrophage inflammatory protein-1beta, and TNF-alpha at the protein and transcript levels. Granulocyte-macrophage CSF was optimally induced by IL-15 and IL-18. Resting CD56+ NK cells expressed IL-18R transcript that was up-regulated by IL-12 or IL-15. Our results show that distinct cytokine and chemokine patterns are induced in NK cells in response to different costimulatory signals from these three monokines. This suggests that NK cell cytokine production may be governed in part by the monokine milieu induced during the early proinflammatory response to infection and by the subset of NK cells present at the site of inflammation.

Co-stimulation of human decidual natural killer cells by interleukin-2 and stromal cells. (6/766)At the late secretory phase of the menstrual cycle and in early pregnancy, the uterine mucosa is infiltrated by large numbers of natural killer (NK) cells with a distinctive phenotype (CD56bright CD16- CD3-) and large granular lymphocyte (LGL) morphology. Circulating CD56bright NK cells generally proliferate in the presence of interleukin-2 (IL-2), but it is clear that cofactors besides IL-2 are required for optimal response. In the bone marrow, this co-stimulating signal is provided by stromal cells. In the present study we observe that uterine CD56+ cells from early pregnancy decidua similarly proliferate vigorously when cultured with decidual stromal cells and a suboptimal dose of IL-2. This response is dependent on cell-cell contact, as no proliferation of decidual NK cells was observed when they were separated from stromal cells by a permeable cyclopore membrane. In addition, we have studied the expression of Bcl-2 by decidual CD56+ cells. Our results show that the microenvironment of the uterus is likely to have a significant influence on the proliferation and survival of uterine CD56+ cells. (+info)
Apoptosis of human endometrium mediated by perforin and granzyme B of NK cells and cytotoxic T lymphocytes. (7/766)Endometrial stromal granulocytes (EGs) were found to be a major component of human endometrial stroma in the late secretory phase. However, the role of EGs in the mechanism of human endometrial menstruation has not been clarified. Immunohistochemistry of CD56, perforin, granzyme B, and vimentin, in situ detection of apoptosis by TUNEL (TdT-mediated dUTP-biotin nick and labeling) and electron microscopy were performed in endometrial tissue samples with normal menstrual cycles. We analyzed the number of immunostained cells in the functional layer of stroma and the number of apoptotic cells detected by TUNEL in the endometrial glandular cells. Double-staining revealed that CD56-positive endometrial stromal cells were simultaneously positive for both perforin and granzyme B, and negative for vimentin, which recognized stromal tissue. Vimentin was positive for the predecidual cells and negative for EGs. CD56-positive EGs involving perforin and granzyme B were progressively recruited during the secretory phases before menstruation. Apoptosis in endometrial glandular cells increased from the late secretory phase, which maximized at the menstrual period. This finding suggests that the cytotoxic granules released from EGs, which are derived from cytotoxic T lymphocytes and natural killer cells, are initiators of the apoptotic pathway that induces endometrial menstruation.

A case of synchronous double primary lung cancer with neuroendocrine features. (8/766)We report a case of unique double primary lung cancers with neuroendocrine features in a 63-year-old male smoker. The mass in the left lower lobe (LLL) was a small cell/large cell carcinoma with spindle cell sarcomatous areas and organoid structure. The mass in the left upper lobe (LUL) was a tubular adenocarcinoma with neuroendocrine features including organoid nests showing occasional rosette formation, nuclear palisading in the periphery of the nests and positive immunoreaction for CD56, chromogranin A and synaptophysin. The difference in histological structures between the two masses led us to diagnose double primary lung cancer. The combination of small cell lung carcinoma and spindle cell carcinoma is very uncommon. The relationship between LLL and LUL tumors remains unclear. Multiple lung cancers with neuroendocrine features have only rarely been reported in the literature. The patient in our case died of widespread cancer 2 years and 4 months after the surgery without adjuvant chemotherapy, a longer postoperative survival time than in cases of ordinary extensive small cell lung cancer. Multiple lung cancers with neuroendocrine features are extremely rare and similar cases have not been reported in the literature. Neuroendocrine differentiation has attracted widespread attention and, therefore, examining neuroendocrine features in lung cancers is important. (+info)

Proteome Analysis of Distinct Developmental Stages of Human Natural Killer Cells The recent Natural Killer (NK) cell maturation model postulates that CD34+ hematopoietic stem cells (HSC) first develop into CD56bright NK cells, then into CD56dimCD57− and finally into terminally maturated CD56dimCD57+. The molecular mechanisms of human NK cell differentiation and maturation however are incompletely characterized. Here we present a proteome analysis of distinct developmental stages of human primary NK cells, isolated from healthy human blood donors. Peptide sequencing was used to comparatively analyze CD56bright NK cells versus CD56dim NK cells and CD56dimCD57− NK cells versus CD56dimCD57+ NK cells and revealed distinct protein signatures for all of these subsets. Quantitative data for about 3400 proteins were obtained and support the current differentiation model. Furthermore, 11 donor-independently, but developmental stage specifically regulated proteins so far un-described in NK cells were ...

Natural killer (NK) cell receptor-HLA ligand genotype combinations associated with protection from HIV infection: investigation...
Natural killer cells respond to stimulation with autologous iCD4. By using fluorochrome conjugated antibody panels it is possible to gate on NK cell populations expressing defined inhibitory NKRs (iNKR) and to detect anti-viral functions such as secretion of IFN-γ/CCL4 and expression of CD107a by flow cytometry. This strategy has been used to explore the factors governing how NK cells from HIV-uninfected persons respond to their first encounter with autologous iCD4.. NKG2A/CD94 is an iNKR expressed on almost all CD56bright and on ~40% of CD56dim NK cells. The ligand for NKG2A in HLA-E, a non-classical MHC-Ib antigen whose cell surface expression depends on binding highly conserved peptides from the leader sequence of many HLA-A, B, C and G MHC-I molecules . HLA-E is expressed on many cell types and maintained on iCD4 . As NKG2A is an iNKR, the interaction of NKG2A with HLA-E on iCD4 should inhibit NK cell activation. However, the highest frequency of functional NK cells induced by ...
Human Decidual Natural Killer Cells Are a Unique NK Cell Subset with Immunomodulatory Potential | JEM
Granularity is a characteristic of both dNK and CD56dim pNK cells, both of which are also called large granular lymphocytes (65), whereas CD56bright pNK cells are known to be less granular (15). Granzyme B and perforin (components of cytotoxic granules) were expressed at similar levels in dNK and CD56dim pNK cells, whereas granzyme A was 3- and 10-fold overexpressed in dNK cells versus the CD56dim and CD56bright pNK cells, respectively (Fig. 3 C). Thus, the potential cytolytic function of dNK cells, probably regulated, cannot be ignored. This nascent activity could be manifest in the decidua under special circumstances (e.g., virus infection of the trophoblast or decidual remodeling).. Many other genes overexpressed in dNK cells that are presented in Fig. 3 (e.g., CD31, CD38, MIP-1 α/β, Syk, LEF1, AARS, arp2/3 subunit, and tubulins) may be of considerable interest but are beyond the scope of the present paper. Likewise, genes that are absent or have lower expression in dNK cells in relation to ...

Cryopreserved CB aliquots were thawed, depleted of monocytes, and cultured in serum-free medium alone or serum-free ...
recurrent miscarriage | Fertility Matters
treatment add-ons, you may be interested in some impartial and expert advice in two new scientific opinion papers published by the Royal College of Obstetricians and Gynaecologists (RCOG). They call for more high quality research into the role of natural killer cells in fertility and the effect of endometrial scratching on pregnancy outcomes.. Scientific Impact Papers (SIP), are up-to-date reviews of emerging or controversial scientific issues. The first paper looks at the role of uterine natural killer (uNK) cells, how they are measured, the role of testing and the evidence behind any links to improving implantation rates and early placental development. The paper clarifies that uNK cells are completely different from peripheral blood natural killer cells (which you would be testing in the blood tests some fertility clinics currently offer).. The paper makes it clear that there is no evidence to offer routine tests for NK cells as part of fertility treatment or testing, and that there is ...

Ex vivo Human Natural Killer (NK) Cell Stimulation and Intracellular IFNγ and CD107a Cytokine Staining -BIO-PROTOCOL
Natural killer (NK) cells comprise 5-20% of peripheral blood mononuclear cells (PBMC) in humans. In addition to their fundamental roles in the defense against viral infections and tumor surveillance, NK cells help shape adaptive immune responses through their production of cytokines. NK cells are traditionally identified as CD3neg, CD14neg, CD19neg lymphocytes expressing CD56. Using a combination of markers that includes CD56 and CD7 greatly increases the ability to define the phenotype and function of NK cell subsets. Two key markers of NK cell function are the production of IFNγ and the release of cytotoxic granules measured by the expression of CD107a. Here we describe a method to assess IFNγ and CD107a expression in NK cells following stimulation with target cells or cytokines. This method can be used to assess the general functional capacity of NK cells in peripheral blood mononuclear cells from a wide range of study participants.

CD337, also known as NKp30, is a 30-kDa transmembrane glycoprotein which is a NK-specific triggering receptor involved in non-MHC-restricted natural cytotoxicity. NKp30 is strictly expressed by all resting and activated NK cells including the minor CD3-CD56brightCD16- subset. With NKp46 and NKp44 it is one of the three identified NK natural cytotoxicity receptors (NCR). Its surface expression parallels that of NKp46. NKp46dull NK cells are also characterised by a NKp30dull phenotype while NKp46bright NK cells show a NKp30bright phenotype. The NKp30bright or NKp30dull phenotypes are correlated with high or low cytotoxicity, respectively. CD337 is a member of the immunoglobulin superfamily characterized by a single extracellular V-type Ig-like domain. It is associated with a homodimer of ITAM motif-containing CD3ζ adaptor proteins. These adaptor proteins are not necessary for surface expression of NKp30, but are necessary for signal transduction. In redirected killing assays, Z25-mediated cross ...

The Assessment of NK Cytotoxicity and CD56+/CD16+ Phenotype by Flowcytometry in PBL Isolated from Women with Recurrent...
Background: Human peripheral blood NK cells constitutively express CD56 and CD16 antigens. Peripheral blood NK cells seem to be strongly related with decidual NK cells, and may reflect the decidual NK cell functional status. There are varied reports concerning the relationship between NK cell cytotoxicity in women with recurrent spontaneous abortion. Objective: To study NK activity in women with history of RSA by using a non-radioactive cytotoxicity assay. Methods: Peripheral blood lymphocytes from RSA and healthy multiparous women were obtained. Lymphocytes were isolated and mixed with K562 NK-sensitive cell line. A non-radioactive method for NK cell cytotoxicity assessment was utilized. Dead K562 cell populations were detected by FACS Calibur flow cytometry, and the data obtained was analysed on cell-Quest software. The proportion of CD16+ /CD56+ cells was then calculated. Results: The proportion of NK cells were 9.21% ± 3.06 and 13.48% ± 4.09 in healthy women and RSA, respectively. The percentage
Super Natural Killer Cells: Modified Lymphocytes Prevent the Spread of Cancer
Now, results from a new study carried out using a mouse model, show that modified cells called super natural killer cells are able to seek out cancer cells in lymph nodes to destroy them, thus halting the process of metastasis. Michael King, senior author of the study, said in a press release: We want to see lymph node metastasis become a thing of the past.. The super natural killer cells find the cancerous cells in the lymph nodes and induce apoptosis - in other words, the cancer cells self-destruct and disintegrate, thus averting their further lymphatic spread. But what are these super natural killer cells? They are a modified version of the so-called natural killer cells - or NK cells for short.. NK cells are a type of lymphocytes that play a major role in the killing of cancer cells and virus-infected cells by inducing apoptosis. To obtain the super version of these lymphocytes, scientists attached nanoparticles to the NK cell surface. These nanoparticles contain a protein dubbed TRAIL ...
CD57 defines a functionally unique subset of NK cells in humans (134.1) | The Journal of Immunology
CD57 is a marker of terminal differentiation on human CD8+ T cells and possibly on human NK cells. Newborn and fetal NK cells do not express CD57, however the frequency of CD57-bearing NK cells increases with age. Utilizing PBMC obtained from healthy donors we are assessing the phenotypic and functional differences between CD57+ and CD57neg NK cells. CD57+ NK cells express different activation markers and a distinct repertoire of NK receptors suggestive of a more mature phenotype. Preliminary data also indicate that there is a higher frequency of IFNγ CD57+ NK cells compare to CD57neg NK cells when stimulated through their activating receptors, CD57+ NK cells are less sensitive to activation-induced apoptosis, and interestingly, proliferate less when co-cultured with target cells and/or cytokines. The combination of a more activated phenotype and a decreased capacity to proliferate suggests CD57+ NK cells are terminally differentiated. Studies are underway to assess the phenotypic and ...
Regulation of IFN-γ production following 2B4 activation in human NK cells<...
TY - JOUR. T1 - Regulation of IFN-γ production following 2B4 activation in human NK cells. AU - Johnson, Lori A.. AU - Goldfarb, Ronald H.. AU - Mathew, Porunelloor. PY - 2000/12/1. Y1 - 2000/12/1. N2 - IFN-γ is a cytokine that regulates various functions of the immune system. The major producers of IFN-γ are T cells and NK cells. 2B4 is a novel activating receptor expressed on all human NK cells, a subset of CD8+ T cells, monocytes and basophils. Activation of human NK cells through surface 2B4 enhances NK cell cytolytic function and secretion of IFN-γ. We have examined the regulation of IFN-γ production by the human NK cell line YT upon activation through surface 2B4. Our data indicate that ligation of surface 2B4 by mAb C1.7, that specifically recognizes 2B4, induces transcriptional activation of IFN-γ.

Blood natural killer cell deficiency reveals an immunotherapy strategy for atopic dermatitis | Science Translational Medicine
The skin condition atopic dermatitis (AD) is driven by a type 2 immune response. Mack et al. performed high-dimensional immune profiling of patients with AD and revealed deficiencies in certain subsets of natural killer (NK) cells. NK cells showed signs of activation-induced cell death and were restored in patients that responded to immunotherapy. Circulating NK cells were also decreased in a mouse AD model; boosting NK cells with an IL-15 superagonist ameliorated symptoms in the mice. These results suggest that strategies to restore NK cells could help rebalance immunity in AD. ...
Rapid expansion and long-term persistence of elevated NK cell numbers in humans infected with hantavirus | JEM
Several experimental models have demonstrated a role for NK cells in host responses against virus infections (Lodoen and Lanier, 2006; Lee et al., 2007). The perhaps most well characterized experimental model system in this respect is that of infection of mice with mouse CMV (Dokun et al., 2001; Lodoen and Lanier, 2006; Sun et al., 2009). In experimental mouse CMV infection, the NK cell response is characterized by proliferation of a specific subset of NK cells that peaks within a few days after infection. Subsequently, this NK cell population undergoes rapid contraction by apoptosis (Dokun et al., 2001; Robbins et al., 2004). To investigate more directly how results from studies of viral infections in experimental model systems compare with infections in humans, we have studied the NK cell response throughout the course of an acute virus infection in humans.. In humans, involvement of NK cells in host responses to viruses were first indicated by the finding that virus-induced IFN-α enhanced NK ...

Frontiers | CCL3 Enhances Antitumor Immune Priming in the Lymph Node via IFNγ with Dependency on Natural Killer Cells |...
Lymph node (LN) plays a critical role in tumor cell survival outside of the primary tumor sites and dictates overall clinical response in many tumor types (1, 2). Previously, we and others have demonstrated that CCL3 plays an essential role in orchestrating T cell-antigen-presenting cell (APC) encounters in the draining LN following vaccination, and such interactions enhance the magnitude of the memory T cell pool (3-5). In the current study, we investigate the cellular responses in the tumor-draining lymph nodes (TDLNs) of a CCL3-secreting CT26 colon tumor (L3TU) as compared to wild-type tumor (WTTU) during the priming phase of an antitumor response (≤10 days). In comparison to WTTU, inoculation of L3TU resulted in suppressed tumor growth, a phenomenon that is accompanied by altered in vivo inflammatory responses on several fronts. Autologous tumor-derived CCL3 (aCCL3) secretion by L3TU bolstered the recruitment of T- and B-lymphocytes, tissue-migratory CD103+ dendritic cells (DCs), and CD49b+

CD56 MicroBeads were developed for the positive selection or depletion of natural killer (NK) cells from human PBMCs or single-cell suspensions from tissues. The CD56 antigen is expressed by most NK cells and a minor T cell subset (CD3+CD56+ NKT cells). Upon activation of NK cells, the surface expression of CD56 is increased. - Italia

Natural killer (NK) cell cytotoxicity is highly dependent on the ability of NK cells to migrate through the extracellular matrix (ECM) microenvironment. Traditional imaging studies of NK cell migration and cytotoxicity have utilized 2-D surfaces, which do not properly reproduce the structural and mechanical cues that shape the migratory response of NK cells in vivo. In addition, current in vivo imaging does not allow for the accurate long-term single-cell imaging required to dissect the functional heterogeneity of NK cell populations, and importantly, it does not allow studies of human cells. Therefore, it is desirable to implement in vitro migration and killing assays that better mimic in vivo conditions.. We have combined a microwell assay that allows long-term imaging and tracking of small, well-defined populations of NK cells with an interstitial ECM-like matrix to more closely approximate in vivo conditions. The microwells, which are loaded with a gel mixture containing NK and target cells, ...
Genetically Enhanced NK cells developed to Eradicate Leukemia Cells
In order to grow large populations of NK cells, the team started with samples of blood containing a variety of different immune system cells. They placed this sample into a dish containing a type of human leukemia cell called K562. Campanas team genetically modified the K562 cells so they carried on their surfaces many copies of two different proteins, 4-1BBL and IL-15. The genetically modified K562 cells quickly stimulated the expansion of the NK cell population to more than10,000 times their original number. The technique triggered growth of NK cells specifically, which greatly simplified the ability of the researchers to collect a pure population of these immune cells ...
