Adoptive Transfer
Form of passive immunization where previously sensitized immunologic agents (cells or serum) are transferred to non-immune recipients. When transfer of cells is used as a therapy for the treatment of neoplasms, it is called adoptive immunotherapy (IMMUNOTHERAPY, ADOPTIVE).
Immunotherapy, Adoptive
Form of adoptive transfer where cells with antitumor activity are transferred to the tumor-bearing host in order to mediate tumor regression. The lymphoid cells commonly used are lymphokine-activated killer (LAK) cells and tumor-infiltrating lymphocytes (TIL). This is usually considered a form of passive immunotherapy. (From DeVita, et al., Cancer, 1993, pp.305-7, 314)
Immunization, Passive
Transfer of immunity from immunized to non-immune host by administration of serum antibodies, or transplantation of lymphocytes (ADOPTIVE TRANSFER).
Mice, Inbred C57BL
Gene Transfer Techniques
The introduction of functional (usually cloned) GENES into cells. A variety of techniques and naturally occurring processes are used for the gene transfer such as cell hybridization, LIPOSOMES or microcell-mediated gene transfer, ELECTROPORATION, chromosome-mediated gene transfer, TRANSFECTION, and GENETIC TRANSDUCTION. Gene transfer may result in genetically transformed cells and individual organisms.
Spleen
An encapsulated lymphatic organ through which venous blood filters.
CD4-Positive T-Lymphocytes
A critical subpopulation of T-lymphocytes involved in the induction of most immunological functions. The HIV virus has selective tropism for the T4 cell which expresses the CD4 phenotypic marker, a receptor for HIV. In fact, the key element in the profound immunosuppression seen in HIV infection is the depletion of this subset of T-lymphocytes.
T-Lymphocytes
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.
Mice, Inbred BALB C
CD8-Positive T-Lymphocytes
A critical subpopulation of regulatory T-lymphocytes involved in MHC Class I-restricted interactions. They include both cytotoxic T-lymphocytes (T-LYMPHOCYTES, CYTOTOXIC) and CD8+ suppressor T-lymphocytes.
Embryo Transfer
The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.
Gene Transfer, Horizontal
The naturally occurring transmission of genetic information between organisms, related or unrelated, circumventing parent-to-offspring transmission. Horizontal gene transfer may occur via a variety of naturally occurring processes such as GENETIC CONJUGATION; GENETIC TRANSDUCTION; and TRANSFECTION. It may result in a change of the recipient organism's genetic composition (TRANSFORMATION, GENETIC).
Mice, Knockout
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.
Lymphocyte Activation
Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

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.
Ovalbumin
An albumin obtained from the white of eggs. It is a member of the serpin superfamily.
Mice, SCID
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.
Dendritic Cells
Specialized cells of the hematopoietic system that have branch-like extensions. 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).
Flow Cytometry
Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
Interferon-gamma
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.
Lymph Nodes
They are oval or bean shaped bodies (1 - 30 mm in diameter) located along the lymphatic system.

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.

An experimental animal model for central nervous system demyelinating disease. Inoculation with a white matter emulsion combined with FREUND'S ADJUVANT, myelin basic protein, or purified central myelin triggers a T cell-mediated immune response directed towards central myelin. The pathologic features are similar to MULTIPLE SCLEROSIS, including perivascular and periventricular foci of inflammation and demyelination. Subpial demyelination underlying meningeal infiltrations also occurs, which is also a feature of ENCEPHALOMYELITIS, ACUTE DISSEMINATED. Passive immunization with T-cells from an afflicted animal to a normal animal also induces this condition. (From Immunol Res 1998;17(1-2):217-27; Raine CS, Textbook of Neuropathology, 2nd ed, p604-5)
Cytokines
Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. 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.
Th1 Cells
Subset of helper-inducer T-lymphocytes which synthesize and secrete interleukin-2, gamma-interferon, and interleukin-12. Due to their ability to kill antigen-presenting cells and their lymphokine-mediated effector activity, Th1 cells are associated with vigorous delayed-type hypersensitivity reactions.

They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.
Receptors, Antigen, T-Cell
Molecules on the surface of T-lymphocytes that recognize and combine with antigens. The receptors are non-covalently associated with a complex of several polypeptides collectively called CD3 antigens (ANTIGENS, CD3).

The family contains seven genera: DELTARETROVIRUS; LENTIVIRUS; RETROVIRUSES TYPE B, MAMMALIAN; ALPHARETROVIRUS; GAMMARETROVIRUS; RETROVIRUSES TYPE D; and SPUMAVIRUS. A key feature of retrovirus biology is the synthesis of a DNA copy of the genome which is integrated into cellular DNA. After integration it is sometimes not expressed but maintained in a latent state (PROVIRUSES).

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.

A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved.

The direct connection is usually made to a healthy postlesional distal portion of a non-functioning nerve or implanted directly into denervated muscle or insensitive skin. Nerve sprouts will grow from the transferred nerve into the denervated elements and establish contact between them and the neurons that formerly controlled another area.
Immunologic Deficiency Syndromes
Syndromes in which there is a deficiency or defect in the mechanisms of immunity, either cellular or humoral.
Signal Transduction
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.

The interaction of CD80 with CD28 ANTIGEN provides a costimulatory signal to T-LYMPHOCYTES, while its interaction with CTLA-4 ANTIGEN may play a role in inducing PERIPHERAL TOLERANCE.

Prevention of collagen-induced arthritis by gene delivery of soluble p75 tumour necrosis factor receptor. (1/4012)

Collagen type II-induced arthritis (CIA) in DBA/1 mice can be passively transferred to SCID mice with spleen B- and T-lymphocytes. In the present study, we show that infection ex vivo of splenocytes from arthritic DBA/1 mice with a retroviral vector, containing cDNA for the soluble form of human p75 receptor of tumour necrosis factor (TNF-R) before transfer, prevents the development of arthritis, bone erosion and joint inflammation in the SCID recipients. Assessment of IgG subclass levels and studies of synovial histology suggest that down-regulating the effector functions of T helper-type 1 (Th1) cells may, at least in part, explain the inhibition of arthritis in the SCID recipients. In contrast, the transfer of splenocytes infected with mouse TNF-alpha gene construct resulted in exacerbated arthritis and enhancement of IgG2a antibody levels. Intriguingly, infection of splenocytes from arthritic DBA/1 mice with a construct for mouse IL-10 had no modulating effect on the transfer of arthritis. The data suggest that manipulation of the immune system with cytokines, or cytokine inhibitors using gene transfer protocols can be an effective approach to ameliorate arthritis.  (+info)

Thymic selection by a single MHC/peptide ligand: autoreactive T cells are low-affinity cells. (2/4012)

In H2-M- mice, the presence of a single peptide, CLIP, bound to MHC class II molecules generates a diverse repertoire of CD4+ cells. In these mice, typical self-peptides are not bound to class II molecules, with the result that a very high proportion of H2-M- CD4+ cells are responsive to the various peptides displayed on normal MHC-compatible APC. We show here, however, that such "self" reactivity is controlled by low-affinity CD4+ cells. These cells give spectacularly high proliferative responses but are virtually unreactive in certain other assays, e.g., skin graft rejection; responses to MHC alloantigens, by contrast, are intense in all assays. Possible explanations for why thymic selection directed to a single peptide curtails self specificity without affecting alloreactivity are discussed.  (+info)

Rapid death of adoptively transferred T cells in acquired immunodeficiency syndrome. (3/4012)

Human immunodeficiency virus (HIV)-specific cytotoxic T lymphocytes (CTL) probably play the major role in controlling HIV replication. However, the value of adoptive transfer of HIV-specific CTL expanded in vitro to HIV+ patients has been limited: this contrasts with the success of CTL therapy in treating or preventing Epstein-Barr virus and cytomegalovirus disease after bone marrow transplantation (BMT). We investigated the fate of expanded HIV-specific CTL clones in vivo following adoptive transfer to a patient with acquired immunodeficiency syndrome (AIDS). Two autologous CTL clones specific for HIV Gag and Pol were expanded to large numbers (>10(9)) in vitro and infused into an HIV-infected patient whose viral load was rising despite antiretroviral therapy. The fate of one clone was monitored by staining peripheral blood mononuclear cells (PBMCs) with T-cell receptor-specific tetrameric major histocompatibility complex (MHC)-peptide complexes. Although the CTL transfer was well tolerated, there were no significant changes in CD4 and CD8 lymphocyte counts and virus load. By tracking an infused clone using soluble MHC-peptide complexes, we show that cells bearing the Gag-specific T-cell receptors were rapidly eliminated within hours of infusion through apoptosis. Thus, the failure of adoptively transferred HIV-specific CTL to reduce virus load in AIDS may be due to rapid apoptosis of the infused cells, triggered by a number of potential mechanisms. Further trials of adoptive transfer of CTL should take into account the susceptibility of infused cells to in vivo apoptosis.  (+info)

Chlamydia infections and heart disease linked through antigenic mimicry. (4/4012)

Chlamydia infections are epidemiologically linked to human heart disease. A peptide from the murine heart muscle-specific alpha myosin heavy chain that has sequence homology to the 60-kilodalton cysteine-rich outer membrane proteins of Chlamydia pneumoniae, C. psittaci, and C. trachomatis was shown to induce autoimmune inflammatory heart disease in mice. Injection of the homologous Chlamydia peptides into mice also induced perivascular inflammation, fibrotic changes, and blood vessel occlusion in the heart, as well as triggering T and B cell reactivity to the homologous endogenous heart muscle-specific peptide. Chlamydia DNA functioned as an adjuvant in the triggering of peptide-induced inflammatory heart disease. Infection with C. trachomatis led to the production of autoantibodies to heart muscle-specific epitopes. Thus, Chlamydia-mediated heart disease is induced by antigenic mimicry of a heart muscle-specific protein.  (+info)

Adoptive transfer of genetically modified macrophages elucidated TGF-beta-mediated 'self-defence' of the glomerulus against local action of macrophages. (5/4012)

TGF-beta has several anti-inflammatory properties which may be relevant to prevention of or recovery from acute glomerular inflammation. Using genetically modified mesangial cells and a technique for in vivo macrophage transfer, this article provides evidence for TGF-beta-mediated 'self-defence' of the glomerulus against macrophages. Rat mesangial cells stably transfected with TGF-beta1 showed a blunted response to the macrophage-derived, proinflammatory cytokine IL-1beta. In contrast, mesangial cells expressing the dominant-interfering TGF-beta receptor showed an enhanced response to IL-1. Similarly, externally added TGF-beta1 inhibited the cytokine response of normal glomeruli, and isolated nephritic glomeruli producing active TGF-beta1 showed a depressed response to IL-1beta, compared to normal glomeruli. Consistent with these in vitro results, in vivo transfer of activated macrophages revealed that the TGF-beta-producing glomeruli are insensitive to the effector action of macrophages. These results indicate that TGF-beta1 functions as an endogenous 'defender' that counteracts local action of activated macrophages in the glomerulus.  (+info)

Efficient IgG-mediated suppression of primary antibody responses in Fcgamma receptor-deficient mice. (6/4012)

IgG antibodies can suppress more than 99% of the antibody response against the antigen to which they bind. This is used clinically to prevent rhesus-negative (Rh-) women from becoming immunized against Rh+ erythrocytes from their fetuses. The suppressive mechanism is poorly understood, but it has been proposed that IgG/erythrocyte complexes bind to the inhibitory Fc receptor for IgG (FcgammaRIIB) on the B cell surface, thereby triggering negative signals that turn off the B cell. We show that IgG induces the same degree of suppression of the response to sheep erythrocytes in animals lacking the known IgG-binding receptors FcgammaRIIB, FcgammaRI + III, FcgammaRI + IIB + III, and FcRn (the neonatal Fc receptor) as in wild-type animals. Reinvestigation of the ability of F(ab')2 fragments to suppress antibody responses demonstrated that they were nearly as efficient as intact IgG. In addition, monoclonal IgE also was shown to be suppressive. These findings suggest that IgG inhibits antibody responses through Fc-independent mechanisms, most likely by masking of antigenic epitopes, thereby preventing B cells from binding and responding to antigen. In agreement with this, we show that T cell priming is not abolished by passively administered IgG. The results have implications for the understanding of in vivo regulation of antibody responses and Rh prophylaxis.  (+info)

Tolerance to antigen-presenting cell-depleted islet allografts is CD4 T cell dependent. (7/4012)

Pretreatment of pancreatic islets in 95% oxygen culture depletes graft-associated APCs and leads to indefinite allograft acceptance in immunocompetent recipients. As such, the APC-depleted allograft represents a model of peripheral alloantigen presentation in the absence of donor-derived costimulation. Over time, a state of donor-specific tolerance develops in which recipients are resistant to donor APC-induced graft rejection. Thus, persistence of the graft is sufficient to induce tolerance independent of other immune interventions. Donor-specific tolerance could be adoptively transferred to immune-deficient SCID recipient mice transplanted with fresh immunogenic islet allografts, indicating that the original recipient was not simply "ignorant" of donor antigens. Interestingly, despite the fact that the original islet allograft presented only MHC class I alloantigens, CD8+ T cells obtained from tolerant animals readily collaborated with naive CD4+ T cells to reject donor-type islet grafts. Conversely, tolerant CD4+ T cells failed to collaborate effectively with naive CD8+ T cells for the rejection of donor-type grafts. In conclusion, the MHC class I+, II- islet allograft paradoxically leads to a change in the donor-reactive CD4 T cell subset and not in the CD8 subset. We hypothesize that the tolerant state is not due to direct class I alloantigen presentation to CD8 T cells but, rather, occurs via the indirect pathway of donor Ag presentation to CD4 T cells in the context of host MHC class II molecules.  (+info)

Mucosal immunity to influenza without IgA: an IgA knockout mouse model. (8/4012)

IgA knockout mice (IgA-/-) were generated by gene targeting and were used to determine the role of IgA in protection against mucosal infection by influenza and the value of immunization for preferential induction of secretory IgA. Aerosol challenge of naive IgA-/- mice and their wild-type IgA+/+ littermates with sublethal and lethal doses of influenza virus resulted in similar levels of pulmonary virus infection and mortality. Intranasal and i.p. immunization with influenza vaccine plus cholera toxin/cholera toxin B induced significant mucosal and serum influenza hemagglutinin-specific IgA Abs in IgA+/+ (but not IgA-/-) mice as well as IgG and IgM Abs in both IgA-/- and IgA+/+ mice; both exhibited similar levels of pulmonary and nasal virus replication and mortality following a lethal influenza virus challenge. Monoclonal anti-hemagglutinin IgG1, IgG2a, IgM, and polymeric IgA Abs were equally effective in preventing influenza virus infection in IgA-/- mice. These results indicate that IgA is not required for prevention of influenza virus infection and disease. Indeed, while mucosal immunization for selective induction of IgA against influenza may constitute a useful approach for control of influenza and other respiratory viral infections, strategies that stimulate other Igs in addition may be more desirable.  (+info)

TY - JOUR. T1 - Role of T cell receptor affinity in the efficacy and specificity of adoptive T cell therapies. AU - Stone, Jennifer D.. AU - Kranz, David M.. PY - 2013. Y1 - 2013. N2 - Over the last several years, there has been considerable progress in the treatment of cancer using gene modified adoptive T cell therapies. Two approaches have been used, one involving the introduction of a conventional αβ T cell receptor (TCR) against a pepMHC cancer antigen, and the second involving introduction of a chimeric antigen receptor (CAR) consisting of a single-chain antibody as an Fvfragment linked to transmembrane and signaling domains. In this review, we focus on one aspect of TCR-mediated adoptive T cell therapies, the impact of the affinity of the aß TCR for the pepMHC cancer antigen on both efficacy and specificity. We discuss the advantages of higher-affinity TCRs in mediating potent activity of CD4 T cells. This is balanced with the potential disadvantage of higher-affinity TCRs in mediating ...

A novel adoptive transfer model of chronic lymphocytic leukemia suggests a key role for T lymphocytes in the diseaseA novel adoptive transfer model of chronic lymphocytic leukemia suggests a key role for T lymphocytes in the disease
Chronic lymphocytic leukemia (CLL) is an incurable adult disease of unknown etiology. Understanding the biology of CLL cells, particularly cell maturation and growth in vivo, has been impeded by lack of a reproducible adoptive transfer model. We report a simple, reproducible system in which primary CLL cells proliferate in nonobese diabetes/severe combined immunodeficiency/γc(null) mice under the influence of activated CLL-derived T lymphocytes. By co-transferring autologous T lymphocytes, activated in vivo by alloantigens, the survival and growth of primary CFSE-labeled CLL cells in vivo is achieved and quantified. Using this approach, we have identified key roles for CD4(+) T cells in CLL expansion, a direct link between CD38 expression by leukemic B cells and their activation, and support for CLL cells preferentially proliferating in secondary lymphoid tissues. The model should simplify analyzing kinetics of CLL cells in vivo, deciphering involvement of nonleukemic elements and nongenetic ...

Active Immunotherapy and Adoptive Cell Transfer as an Effective Cancer by Philip Jay CynamonActive Immunotherapy and Adoptive Cell Transfer as an Effective Cancer by Philip Jay Cynamon
There are many ways to fight cancer using the bodys own immune system. Some methods include the administration of vaccines while others involve stimulatory factors injected near tumors. One promising method is enlisting the help of T cells. To fight cancer effectively, T cells must be able to recognize cancerous antigens and the environment in which these T cells reside must be conducive to their function, survival, and proliferation. This paper discusses a method of providing such an environment called adoptive cell transfer, as well as the elements that effect this protocol and the ways in which the environment can be manipulated to increase the effectiveness of adoptive cell transfer. Many factors contribute to the observation that the effectiveness of adoptive cell transfer increases as immunodepletion increases, namely, the depletion of regulatory T cells. Additionally, the existence of natural killer cells during adoptive cell transfer has been shown to decrease its effectiveness. Also, increased

British Library EThOS: Genetic control of MTOR to improve adoptive T cell therapy of tumoursBritish Library EThOS: Genetic control of MTOR to improve adoptive T cell therapy of tumours
Adoptive T cell therapy to treat cancer in combination with re-directing specificity through T cell receptor (TCR) gene transfer, represents an effective therapeutic option. However, reduced effector responses due to the immunosuppressive tumour microenvironment and insufficient long-term engraftment of transferred cells represent two potential limitations. Tumours often employ mechanisms to inhibit T cell responses including secretion of TGFβ and depleting the tumour microenvironment of amino acids. The main aim of this PhD project was to develop a strategy to enhance T cell function for tumour therapy. The mammalian target of rapamycin (mTOR) pathway regulates CD8 T cell differentiation such that high mTOR activation leads to enhanced effector whilst low mTOR activation leads to increased T cell memory formation. Two retrovirus constructs have been designed whereby one expresses the positive mTOR regulator Rheb and the other expresses the negative mTOR regulator Pras40. Rheb transduction into ...

High-affinity oligoclonal TCRs define effective adoptive T cell therapy targeting mutant KRAS-G12D | PNASHigh-affinity oligoclonal TCRs define effective adoptive T cell therapy targeting mutant KRAS-G12D | PNAS
Complete cancer regression occurs in a subset of patients following adoptive T cell therapy (ACT) of ex vivo expanded tumor-infiltrating lymphocytes (TILs). However, the low success rate presents a great challenge to broader clinical application. To provide insight into TIL-based immunotherapy, we studied a successful case of ACT where regression was observed against tumors carrying the hotspot mutation G12D in the KRAS oncogene. Four T cell receptors (TCRs) made up the TIL infusion and recognized two KRAS-G12D neoantigens, a nonamer and a decamer, all restricted by human leukocyte antigen (HLA) C*08:02. Three of them (TCR9a, 9b, and 9c) were nonamer-specific, while one was decamer-specific (TCR10). We show that only mutant G12D but not the wild-type peptides stabilized HLA-C*08:02 due to the formation of a critical anchor salt bridge to HLA-C. Therapeutic TCRs exhibited high affinities, ranging from nanomolar to low micromolar. Intriguingly, TCR binding affinities to HLA-C inversely correlated ...

Impact of IL-7 signaling on adoptive T cell therapyImpact of IL-7 signaling on adoptive T cell therapy
Interleukin-7 (IL-7) is an essential cytokine required for the development and maintenance of mature T cell. Its availability is limited under normal conditions, but rises during lymphopenia, leading to increased T cell proliferation. The administration of recombinant IL-7 to normal or lymphopenic mice and humans results in increased T cell numbers and altered T cell phenotype. Hence, IL-7 administration could mediate therapeutic benefits in immunocompromised patients and is currently tested in several clinical trials. However, besides its well-studied effects on T cells little is known about the effect of IL-7 on other immune and non-immune cells and their influence on T cell homeostasis. Therefore, we evaluated the effect of IL-7 therapy on adoptively transferred T cells in IL-7 receptor (IL-7R)-competent and IL-7R-deficient lymphopenic mice. We confirm the benefits of IL-7 therapy on T cell responses but additionally show that many of these effects are dependent on IL-7R expression by host ...

JCI - Coaxing the liver into preventing autoimmune disease in the brainJCI - Coaxing the liver into preventing autoimmune disease in the brain
Mechanistically, the authors showed again that peripheral CD4+CD25+Foxp3+ Tregs mediated tolerance, while the results of experiments in T cell receptor transgenic animals showed no evidence for clonal deletion of MBP-reactive effector T cells, despite some level of expression in the thymus of liver MBP-transgenic mice (20). Importantly, expression of MBP in the skin did not protect against EAE, which indicates that expression of this protein in the hepatic environment is critical. In an elegant set of experiments based on adoptive transfer of Tregs and effector T cells labeled with fluorescent dye, the authors showed that Tregs induced by hepatic expression can turn effector T cells into Tregs by inducing expression of the transcription factor Foxp3. Effector T cells lacking TGF-β receptor II were resistant to this infectious tolerance mechanism, indicating dependence on TGF-β signaling. These findings are reminiscent of TGF-β-dependent suppression of CD8+ T cells by CD4+CD25+Foxp3+ Tregs ...

Purpose: : Th17 cells were identified to be highly immunopathogenic in several autoimmune models, including experimental autoimmune uveitis (EAU). More recently, however, the Th17 population was reported by Cuas group to also include a subset of non-pathogenic cells (McGeachy et al., Nature Immunol, 2007). Here we examined this dichotomy by a system of adoptively transferred ocular inflammation. Methods: : Naïve CD4 TCR transgenic cells specific against hen egg lysozyme (HEL) were activated with APC and HEL (APC/HEL), or with plate-bound anti-CD3/CD28 antibodies (PbAb) during polarization with IL-6 and TGF-beta. The cultured cells were tested for production of cytokines, chemokines and chemokine receptors, as well as their capacity to adoptively transfer ocular inflammation in recipient mice expressing HEL in their eyes. Results: : The two culturing procedures yielded populations with similar levels of IL-17 producing cells (~35%) and similar levels of IL-10, but with remarkably different ...

MALT1 protease: equilibrating immunity versus tolerance | The EMBO JournalMALT1 protease: equilibrating immunity versus tolerance | The EMBO Journal
The reported duality of the MALT1 protease to promote cell intrinsic T‐cell effector functions and to suppress activated T cells in a Treg‐dependent manner raises a number of interesting questions. Even though the adoptive transfer demonstrates the potential of Tregs to counteract the autoimmunity, it remains open, if the reduced number of Tregs is indeed sufficient to cause the inflammatory phenotype. In the adoptive transfer experiment, only very few Tregs are sufficient to rescue the autoimmune phenotype raising the possibility that MALT1C472A/C472A Tregs may be less functional. In addition, the increase in IFN‐γ and IL‐4 production in MALT1 protease mutant mice may also indicate that deregulated T‐cell effector functions could also be involved in the early onset of gastritis, which is no longer counteracted due to the loss of peripheral T‐cell tolerance. In this respect, it remains an unresolved question why the autoimmune phenotype is manifested as gastritis. One can speculate ...

Purpose: To determine the antitumor efficacy and toxicity of a novel combination approach involving adoptive T cell immunotherapy utilizing chimeric antigen receptor (CAR) T cells with an immunomodulatory reagent for blocking immunosuppression. Experimental Design: We examined whether administration of a PD-1 blocking antibody could increase the therapeutic activity of CAR T cells against two different Her-2+ tumors. The use of a self-antigen mouse model enabled investigation into the efficacy, mechanism and toxicity of this combination approach. Results: In this study we first demonstrated a significant increase in the level of PD-1 expressed on transduced anti-Her-2 CD8+ T cells following antigen-specific stimulation with PD-L1+ tumor cells and that markers of activation and proliferation were increased in anti-Her-2 T cells in the presence of anti-PD-1 antibody. In adoptive transfer studies in Her-2 transgenic recipient mice, we demonstrated a significant improvement in growth inhibition of ...

BACKGROUND. Chimeric antigen receptor (CAR) T cells can induce remission in highly refractory leukemia and lymphoma subjects, yet the parameters for achieving sustained relapse-free survival are not fully delineated. METHODS. We analyzed 43 pediatric and young adult subjects participating in a phase I trial of defined composition CD19 CAR T cells (ClinicalTrials.gov, NCT02028455). CAR T cell phenotype, function, and expansion, as well as starting material T cell repertoire, were analyzed in relationship to therapeutic outcome (defined as achieving complete remission within 63 days) and duration of leukemia-free survival and B cell aplasia. RESULTS. These analyses reveal that initial therapeutic failures (n = 5) were associated with attenuated CAR T cell expansion and/or rapid attrition of functional CAR effector cells following adoptive transfer. The CAR T products were similar in phenotype and function when compared with products resulting in sustained remissions. However, the initial apheresed ...

Adoptive cell transfer - WikipediaAdoptive cell transfer - Wikipedia
Adoptive cell transfer (ACT) is the transfer of cells into a patient. The cells may have originated from the patient or from another individual. The cells are most commonly derived from the immune system with the goal of improving immune functionality and characteristics. In autologous cancer immunotherapy, T cells are extracted from the patient, genetically modified and cultured in vitro and returned to the same patient. Comparatively, allogeneic therapies involve cells isolated and expanded from a donor separate from the patient receiving the cells. In the 1960s, lymphocytes were discovered to be the mediators of allograft rejection in animals. Attempts to use T cells to treat transplanted murine tumors required cultivating and manipulating T cells in culture. Syngeneic lymphocytes were transferred from rodents heavily immunized against the tumor to inhibit growth of small established tumors, becoming the first example of ACT. Description of T cell growth factor interleukin-2 (IL-2) in 1976 ...

We have examined the migration of murine macrophages from the vascular compartment to normal and inflammatory tissues by the adoptive transfer of resident peritoneal macrophages (RPM phi) fluorescently labeled with the hydrophobic dye 1,1-dioctadecyl 3,3,3,3-tetramethylindocarbocyanine perchlorate (DiI). After initial labeling of the plasma membrane of RPM phi, the dye accumulated stably in intracellular vesicles of low density (rho = 1.042-1.045 kg/l) and cells remained viable in culture for 4 weeks. Like the normal monocyte, DiI-RPM phi, but not exudate-derived or fixed cells, migrated to peritoneal exudates, following i.v. adoptive transfer, by a mechanism inhibitable by an antibody to the type 3 complement receptor. In the absence of an inflammatory stimulus there was no migration to the peritoneal cavity, and DiI-RPM phi accumulated within 4 h in the red pulp and marginal zone of the spleen. By day 6 these cells still formed a tight ring of fluorescence in the marginal zone alone, ...

Patients are being offered admission to this study to test the side effects of an investigational treatment prepared from special immune cells (T cells) specific for melanoma. A T-cell is a type of lymphocyte. Lymphocytes are a type of white blood cell that protect people from viral infections; help other cells fight bacterial and fungal infections; produce antibodies; fight cancers; and coordinate the activities of other cells in the immune system. These special immune cells will be taken from a sample of the patients tumor tissue that will be surgically removed from their body and grown in the laboratory. They will then given back to the patient in their veins. These cells are called tumor infiltrating lymphocytes (TIL). We wish to study the side effects of TIL when they are given with two chemotherapy drugs to temporarily decrease the patients own immune cells and a drug called Interleukin-2 (IL-2).

OT could not be induced in CCR9−/− or β7−/− mice, or when MAdCAM-1 was blocked in wild-type mice, indicating that gut-homing receptors are required for oral tolerization. Consistent with the role of all-trans retinoic acid in inducing gut homing T cells, OT could not be induced in mice depleted of vitamin A. OT was rescued in CCR9−/− mice following adoptive transfer of wild-type T cells, but not CCR9−/− or β7−/− T cells. Gut-homing T cells are therefore necessary and sufficient to induce OT. Wild-type TREG cells and IL-10 were required to restore OT to CCR9−/− mice, indicating that homing and functional differentiation of IL-10-producing TREG cells in the gut is required for OT. Conversely, transfer of CCR9−/− or β7−/− T cells to wild-type mice partially inhibited OT ...

Separate Roles for Antigen Recognition and Lymph Node Inflammation in CD8+ Memory T Cell Formation | The Journal of ImmunologySeparate Roles for Antigen Recognition and Lymph Node Inflammation in CD8+ Memory T Cell Formation | The Journal of Immunology
Lymph node activation is an intrinsic aspect of T cell activation by infectious pathogens and vaccines. We separated the T cell priming event from lymph node activation in space and time by exploiting an experimental model consisting of TCR-transgenic OT-I CD8+ T cells and engineered APCs expressing high levels of the cognate OVA-derived peptide epitope and the costimulatory ligand CD80. Prior work had demonstrated that a 20-h in vitro encounter with these APCs empowered naive OT-I cells to vigorously proliferate in vivo upon transfer to naive syngeneic recipient (15). Furthermore, these T cells were shown to develop into long-lived memory cells, capable of clonal expansion and protective effector function in response to secondary Ag encounter (16). Importantly, progression of the 20 h primed OT-I T cells through primary expansion, contraction, and memory phases required neither in vivo exposure to Ag nor the context of an inflamed, congested lymph node. This model therefore offered a unique ...

We explored the function of endogenous type I IFNs (IFN-1) in the colon using the T cell adoptive transfer model of colitis. Colon mononuclear phagocytes (MPs) constitutively produced IFN-1 in a Toll/IL-1R domain-containing adapter-inducing IFN-β-dependent manner. Transfer of CD4(+)CD45RB(hi) T cells from wild-type (WT) or IFN-α/β receptor subunit 1 knockout (IFNAR1(-/-)) mice into RAG(-/-) hosts resulted in similar onset and severity of colitis. In contrast, RAG(-/-) × IFNAR1(-/-) double knockout (DKO) mice developed accelerated severe colitis compared with RAG(-/-) hosts when transferred with WT CD4(+)CD45RB(hi) T cells. IFNAR signaling on host hematopoietic cells was required to delay colitis development. MPs isolated from the colon lamina propria of IFNAR1(-/-) mice produced less IL-10, IL-1R antagonist, and IL-27 compared with WT MPs. Accelerated colitis development in DKO mice was characterized by early T cell proliferation and accumulation of CD11b(+)CD103(-) dendritic cells in the mesenteric

Cellular immunotherapy as a beacon of hope for hematological malignanciesCellular immunotherapy as a beacon of hope for hematological malignancies
The key component of adoptive T cell therapy is generation of functional tumor-specific T cells without immune tolerance to self-antigens. This can be accomplished by genetic modification of patient T cells using genes encoding CARs. Recently, the third-generation of CAR T cells has been developed, which includes an additional co-stimulatory domain, such as CD28 plus 4-1BB or CD28 plus OX40 together with CD3zeta along with the specific target. Results from several clinical trials in different settings including CAR design, culture techniques, lymphodepleting strategies, and target diseases, have provided valuable insights, and CAR T cells are emerging as a powerful therapy in hematologic malignancies [6]. Most clinical successes of CAR T cell therapy are recorded in the setting of B-cell malignancies, by targeting CD19 (Table 1). Several B cell antigens, such as CD20, CD22, CD23, and CD38 are under evaluation as alternative CAR T cell targets in B-cell malignancies. However, targets that are ...

The data presented show that IFN-I and their signal transducer STAT-1 essentially contribute to the induction of OVA-specific CTL following immunization with OVA peptide and IC31 immune adjuvant. Surprisingly and contrasting many experimental situations with pathogen-specific CTL, OVA-specific CTL did not require IFN-I/STAT-1 as an activation/survival signal. This was shown by the use of conditional IFNAR1 deletion and by adoptive transfer of wt or STAT-1-mutant OT-1 CD8+ T cells into STAT-1-deficient animals. By contrast, adoptive transfer experiments with myeloid DC showed that IFN-I/STAT-1 are required to render these cells fully capable of stimulating CD8+ T cell activation. The IFN-I/STAT-1 effect most likely results from the ability to stimulate DC maturation and activation (35, 36, 37, 38). The reported stimulation of cross-presentation by DC may account for the stronger effect of IFN-I/STAT-1 in vivo when compared with our in vitro experiments, because immunization with the OVA/IC31 ...

Adoptive Cell Therapy-Act 1: The Beginning - The ASCO PostAdoptive Cell Therapy-Act 1: The Beginning - The ASCO Post
Further verification of a graft-vs-tumor effect came from efforts to treat patients for posttransplant leukemic recurrence by infusing viable donor lymphocytes, resulting in sustained complete remissions in most patients with chronic myelogenous leukemia and in some patients with other hematologic malignancies.11 By the mid-1980s, it was generally accepted that adoptive transfer of allogeneic T cells could be of benefit, but was of limited potency, sometimes associated with significant toxicity in the form of graft-vs-host disease and restricted in its application to the post-allogeneic transplant setting.12 To make adoptive cell therapy more effective and broadly applicable, a large number of challenges presented themselves, including the requirement to be able to clone and expand tumor-reactive T cells, to define conditions that allow for their expansion and survival after reinfusion, to identify appropriate tumor-associated targets, and to develop methods to genetically engineer T cells to ...

In the May 5, 2017, issue of Science Immunology, cancer researchers at the Medical University of South Carolina report that blood platelets blunt the immune response to cancer. Genetic inactivation of platelets improved the ability of T cells to fight melanoma in preclinical tests. Adoptive T cell therapies for cancer could be enhanced when combined with common antiplatelet drugs.
