Abstract
Cell and gene therapies hold tremendous promise for treating a range of difficult-to-treat diseases. However, concerns over the safety and efficacy require to be further addressed in order to realize their full potential. Synthetic receptors, a synthetic biology tool that can precisely control the function of therapeutic cells and genetic modules, have been rapidly developed and applied as a powerful solution. Delicately designed and engineered, they can be applied to finetune the therapeutic activities, i.e., to regulate production of dosed, bioactive payloads by sensing and processing user-defined signals or biomarkers. This review provides an overview of diverse synthetic receptor systems being used to reprogram therapeutic cells and their wide applications in biomedical research. With a special focus on four synthetic receptor systems at the forefront, including chimeric antigen receptors (CARs) and synthetic Notch (synNotch) receptors, we address the generalized strategies to design, construct and improve synthetic receptors. Meanwhile, we also highlight the expanding landscape of therapeutic applications of the synthetic receptor systems as well as current challenges in their clinical translation.

A chemically inducible IL-2 receptor signaling complex allows for effective in vitro and in vivo selection of engineered CD4+ T cells. Mol Ther 2023; 31:2472-2488.

Abstract
Engineered T cells represent an emerging therapeutic modality. However, complex engineering strategies can present a challenge for enriching and expanding therapeutic cells at clinical scale. In addition, lack of in vivo cytokine support can lead to poor engraftment of transferred T cells, including regulatory T cells (Treg). Here, we establish a cell-intrinsic selection system that leverages the dependency of primary T cells on IL-2 signaling. FRB-IL2RB and FKBP-IL2RG fusion proteins were identified permitting selective expansion of primary CD4+ T cells in rapamycin supplemented medium. This chemically inducible signaling complex (CISC) was subsequently incorporated into HDR donor templates designed to drive expression of the Treg master regulator FOXP3. Following editing of CD4+ T cells, CISC+ engineered Treg (CISC EngTreg) were selectively expanded using rapamycin and maintained Treg activity. Following transfer into immunodeficient mice treated with rapamycin, CISC EngTreg exhibited sustained engraftment in the absence of IL-2. Furthermore, in vivo CISC engagement increased the therapeutic activity of CISC EngTreg. Finally, an editing strategy targeting the TRAC locus permitted generation and selective enrichment of CISC+ functional CD19-CAR-T cells. Together, CISC provides a robust platform to achieve both in vitro enrichment and in vivo engraftment and activation, features likely beneficial across multiple gene-edited T cell applications.

Canonical Wnt signaling activation by chimeric antigen receptors for efficient cardiac differentiation from mouse embryonic stem cells. Inflamm Regen 2023; 43:11. [PMID: 36765434 PMCID: PMC9912504 DOI: 10.1186/s41232-023-00258-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Accepted: 01/15/2023] [Indexed: 02/12/2023] Open
Abstract
BACKGROUND Canonical Wnt signaling is involved in a variety of biological processes including stem cell renewal and differentiation, embryonic development, and tissue regeneration. Previous studies reported the stage-specific roles of the Wnt signaling in heart development. Canonical Wnt signal activation by recombinant Wnt3a in the early phase of differentiation enhances the efficiency of myocardial cell production from pluripotent stem cells. However, the hydrophobicity of Wnt proteins results in high cost to produce the recombinant proteins and presents an obstacle to their preparation and application for therapeutics, cell therapy, or molecular analysis of Wnt signaling. METHODS To solve this problem, we generated an inexpensive molecule-responsive differentiation-inducing chimeric antigen receptor (designated as diCAR) that can activate Wnt3a signaling. The extracellular domains of low-density-lipoprotein receptor-related protein 6 (LRP6) and frizzeled-8 (FZD8) were replaced with single-chain Fv of anti-fluorescein (FL) antibody, which can respond to FL-conjugated bovine serum albumin (BSA-FL) as a cognate ligand. We then analyzed the effect of this diCAR on Wnt signal activation and cardiomyocyte differentiation of mouse embryonic stem cells in response to BSA-FL treatment. RESULTS Embryonic stem cell lines stably expressing this paired diCAR, named Wnt3a-diCAR, showed TCF/β-catenin-dependent transactivation by BSA-FL in a dose-dependent manner. Treatment with either Wnt3a recombinant protein or BSA-FL in the early phase of differentiation revealed similar changes of global gene expressions and resulted in efficient myocardial cell differentiation. Furthermore, BSA-FL-mediated signal activation was not affected by a Wnt3a antagonist, Dkk1, suggesting that the signal transduction via Wnt3a-diCAR is independent of endogenous LRP6 or FZD8. CONCLUSION We anticipate that Wnt3a-diCAR enables target-specific signal activation, and could be an economical and powerful tool for stem cell-based regeneration therapy.

Testicular subcutaneous allografting followed by immunosuppressive treatment promotes maintenance of spermatogonial cells in rainbow trout (Oncorhynchus mykiss). FISH & SHELLFISH IMMUNOLOGY 2021; 112:108-115.

Abstract
Germ cell transplantation and testis graft represent promising biotechnologies that can be applied for the reproduction of commercial or endangered species. However, mechanisms of rejection from the host immune system might remove the transplanted donor cells/tissues and limit the surrogate production of gametes. In this work, we administered emulsion containing-immunosuppressants to verify whether they are capable to prevent immune rejection and promote survival of testis allografts in rainbow trout. In the first part of this study, we demonstrated in vitro that tacrolimus and cyclosporine were able to affect viability, inhibit leucocyte proliferation, and suppress il2 expression in vitro. In in vivo experiments, both doses of tacrolimus (0.5 and 1.5 mg/kg) and the lower dose of cyclosporine (20 mg/kg) significantly inhibited the expression of il2 in head kidney, three days post-injection. A higher dose of cyclosporine (40 mg/kg) was able to inhibit il2 expression for up to seven days post-injection. In the second part, testis allografts were conducted in fish treated weekly with emulsion containing-tacrolimus. Immunohistochemical, conventional histology, and qRT-PCR (vasa) analysis demonstrated the presence of spermatogonial cells by the fifth week, in animals treated with 0.5 mg/kg of tacrolimus similar as found in autografted group. In the group treated with the highest tacrolimus dose (1.5 mg/kg) and in the non-treated group (without immunosuppressant), no germ cells or their respective markers were detected. il2 expression in head kidney was also suppressed in grafted animals treated with tacrolimus compared to non-treated group. These results suggest that tacrolimus may be a promising immunosuppressant for testis allografts or germ cell transplantation in rainbow trout. Co-administration combining tacrolimus (at lower dose) with other immunosuppressive drugs for inhibiting other activation pathways of the immune system, as performed in human organ transplantation, could be an alternative approach to optimize the immunosuppressive effects in host organisms.

Ozone nanobubble modulates the innate defense system of Nile tilapia (Oreochromis niloticus) against Streptococcus agalactiae. FISH & SHELLFISH IMMUNOLOGY 2021; 112:64-73. [PMID: 33667674 DOI: 10.1016/j.fsi.2021.02.015] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2020] [Revised: 02/06/2021] [Accepted: 02/25/2021] [Indexed: 06/12/2023]
Abstract
Ozone nanobubble (NB-O3) is a promising technology for improving dissolved oxygen and reducing bacterial concentration in aquaculture systems. Here, we investigated the effects of NB-O3 on the innate immunity of fish by monitoring the expression levels of nonspecific immune-related genes (IL-1β, IL-2β, TNF-α), heat-shock protein genes (HSP70, HSP90-α), and a bacteriolytic enzyme, C-type lysozyme, gene (LYZ) post-treatment with this technology. Following exposure to NB-O3, the different tissues of Nile tilapia (Oreochromis niloticus) were collected over time for quantitative real-time PCR (qPCR) analysis. The expression of all the genes evaluated in the gills, the head kidney, and the spleen of the NB-O3 treated group was significantly up-regulated compared to that in the untreated control group. The expression levels were the highest (approx. 2 to 4-fold) at 15 min and 3 h post-exposure and then decreased from 6 to 24 h. These findings suggested that NB-O3 could switch on the innate immunity genes of Nile tilapia. Thus, we hypothesized that the NB-O3-immune-activated fish would respond more effectively to subsequent bacterial infections, thereby improving survivability compared to that of untreated fish. To test this hypothesis, 3 h post NB-O3 exposed fish and unexposed fish were challenged with a lethal dose of Streptococcus agalactiae. Interestingly, the survival rate of the NB-O3 group was significantly higher than that of the non-treated controls, with a relative percent survival (RPS) of 60-70%. Together, these findings indicate, for the first time, that NB-O3 may trigger the nonspecific defense system of the fish, thereby improving fish survivability during subsequent bacterial infections. This research identified another potential benefit of NB-O3 in aquaculture for preventing infectious bacterial diseases.

Abstract
A vast range of biomedical applications relies on the specificity of interactions between an antigen and its cognate receptor or antibody. This specificity can be highest when said antigen is a non-natural (synthetic) molecule introduced into a biological setting as a bio-orthogonal ligand. This review aims to present the development of this methodology from the early discovery of haptens a century ago to the recent clinical trials. We discuss such methodologies as antibody recruitment, artificial internalizing receptors and chemically induced dimerization, present the use of chimeric receptors and/or bispecific antibodies to achieve drug targeting and transcytosis, and illustrate how these platforms most impressively found use in the engineering of therapeutic cells such as the chimeric antigen receptor cells. This review aims to be of interest to a broad scientific audience and to spur the development of synthetic artificial ligands for biomedical applications.

Abstract
B lymphocyte-induced maturation protein-1 (Blimp-1) serves as a master regulator of the development and function of antibody-producing B cells. Given that its function in T lymphocytes has been identified within the past decade, we review recent findings with emphasis on its role in coordinated control of gene expression during the development, differentiation, and function of T cells. Expression of Blimp-1 is mainly confined to activated T cells and is essential for the production of interleukin (IL)-10 by a subset of forkhead box (Fox)p3+ regulatory T cells with an effector phenotype. Blimp-1 is also required to induce cell elimination in the thymus and critically modulates peripheral T cell activation and proliferation. In addition, Blimp-1 promotes T helper (Th) 2 lineage commitment and limits Th1, Th17 and follicular helper T cell differentiation. Furthermore, Blimp-1 coordinates with other transcription factors to regulate expression of IL-2, IL-21 and IL-10 in effector T lymphocytes. In CD8+ T cells, Blimp-1 expression is distinct in heterogeneous populations at the stages of clonal expansion, differentiation, contraction and memory formation when they encounter antigens. Moreover, Blimp-1 plays a fundamental role in coordinating cytokine receptor signaling networks and transcriptional programs to regulate diverse aspects of the formation and function of effector and memory CD8+ T cells and their exhaustion. Blimp-1 also functions as a gatekeeper of T cell activation and suppression to prevent or dampen autoimmune disease, antiviral responses and antitumor immunity. In this review, we discuss the emerging roles of Blimp-1 in the complex regulation of gene networks that regulate the destiny and effector function of T cells and provide a Blimp-1-dominated transcriptional framework for T lymphocyte homeostasis.

Abstract
Biomolecular engineering can be used to purposefully manipulate biomolecules, such as peptides, proteins, nucleic acids and lipids, within the framework of the relations among their structures, functions and properties, as well as their applicability to such areas as developing novel biomaterials, biosensing, bioimaging, and clinical diagnostics and therapeutics. Nanotechnology can also be used to design and tune the sizes, shapes, properties and functionality of nanomaterials. As such, there are considerable overlaps between nanotechnology and biomolecular engineering, in that both are concerned with the structure and behavior of materials on the nanometer scale or smaller. Therefore, in combination with nanotechnology, biomolecular engineering is expected to open up new fields of nanobio/bionanotechnology and to contribute to the development of novel nanobiomaterials, nanobiodevices and nanobiosystems. This review highlights recent studies using engineered biological molecules (e.g., oligonucleotides, peptides, proteins, enzymes, polysaccharides, lipids, biological cofactors and ligands) combined with functional nanomaterials in nanobio/bionanotechnology applications, including therapeutics, diagnostics, biosensing, bioanalysis and biocatalysts. Furthermore, this review focuses on five areas of recent advances in biomolecular engineering: (a) nucleic acid engineering, (b) gene engineering, (c) protein engineering, (d) chemical and enzymatic conjugation technologies, and (e) linker engineering. Precisely engineered nanobiomaterials, nanobiodevices and nanobiosystems are anticipated to emerge as next-generation platforms for bioelectronics, biosensors, biocatalysts, molecular imaging modalities, biological actuators, and biomedical applications.

Abstract
Anti-cancer immunotherapies commonly rely on the use of interleukin-2 (IL-2) to promote the expansion of T lymphocytes. IL-2- dependent proliferation is the culmination of a complex network of phosphorylation-driven signaling events that impact on gene transcription through mechanisms that are not clearly understood. To study the role of IL-2 in the regulation of nuclear protein function we have performed an unbiased mass spectrometry-based study of the nuclear phosphoproteome of resting and IL-2-treated CD4(+) T lymphocytes. We detected 8521distinct phosphosites including many that are not yet reported in curated phosphorylation databases. Although most phosphorylation sites remained unaffected upon IL-2 treatment, 391 sites corresponding to 288 gene products showed robust IL-2-dependent regulation. Importantly, we show that ATP-citrate lyase (ACLY) is a key phosphoprotein effector of IL-2-mediated T-cell responses. ACLY becomes phosphorylated on serine 455 in T lymphocytes upon IL-2-driven activation of AKT, and depletion or inactivation of ACLY compromises IL-2-promoted T-cell growth. Mechanistically, we demonstrate that ACLY is required for enhancing histone acetylation levels and inducing the expression of cell cycle regulating genes in response to IL-2. Thus, the metabolic enzyme ACLY emerges as a bridge between cytokine signaling and proliferation of T lymphocytes, and may be an attractive candidate target for the development of more efficient anti-cancer immunotherapies.

Abstract
A "cytokine-less" in vitro differentiation method would be promising for cost-effective mass production of cells used for regenerative medicine. In this study, we developed a differentiation signalobody S-RANK, in which the extracellular domain of receptor activator of nuclear factor kappa-B (RANK) is replaced with a single-chain variable fragment (scFv) to attain signaling in response to an inexpensive antigen. A murine macrophage cell line RAW264, which is known to differentiate into an osteoclast by RANK ligand (RANKL), was lentivirally transduced with S-RANK. When the resultant cells were cultured with a specific antigen, the cells differentiated into multinucleated tartrate-resistant acid phosphatase-positive osteoclasts. The differentiation efficiency was almost comparable to those induced by RANKL. In addition, the signaling analysis demonstrated that nuclear factor kappa-B and mitogen-activated protein kinase signaling pathways, which are the major signaling pathways downstream of wild-type RANK, were also activated by S-RANK. These results demonstrate that S-RANK sufficiently mimics signal transduction of wild-type RANK. Differentiation signalobodies may be applied for controlling differentiation of other cell types by using appropriate signaling domains.

Abstract
A versatile strategy to inhibit protein functions in the cytoplasmic environment is eagerly anticipated for drug discovery. In this study, we demonstrate a novel system to directly select functional intrabodies from a library in the mammalian cytoplasm. In this system, a target homo-oligomeric antigen is expressed together with a single-chain Fv (scFv) library that is linked to the cytoplasmic domain of a receptor tyrosine kinase (RTK) in the cytoplasm of murine interleukin-3 (IL-3)-dependent cells. As the tyrosine kinase is activated by dimerization, only scFv-RTK clones that can bind to the target antigen would be oligomerized and transduce a growth signal under the IL-3-deprived condition, which leads to selection of functional intrabodies. To demonstrate this system, we used rabies virus phosphoprotein (RV-P) that forms dimers in the cytoplasm as a target antigen. As a result, functional intrabodies were selected using our system from a naïve scFv library as well as from a pre-selected anti-RV-P library generated by phage display. This system may be applied for screening intrabodies that can prevent progression of various severe diseases.

Abstract
Wide applications of antibodies have demanded rapid and easy methods for isolating high-affinity antibodies. We recently developed an antibody screening system in mammalian cells using a growth signalobody, which is a single-chain Fv (scFv) library/cytokine receptor chimera that can transduce a growth signal in response to a target oligomeric antigen. However, we have never investigated how the domain structure of signalobodies affects the outcome of library screening. In this study, we screened naïve scFv library-inserted signalobodies having distinct extracellular and transmembrane (TM) domains. Although the previously constructed signalobody with the extracellular D1/D2 domains of erythropoietin receptor had recovered the clones with high affinity against a target antigen and with low background cell growth, its D1/D2-deficient variant which was tested in this study recovered the clones with low affinity against a target antigen and with considerable background cell growth. In addition, mutagenesis in the TM domain lowered the level of the background cell growth. These results suggest that the D1/D2 domains increase a threshold to activate signalobodies, thereby selecting clones with high affinity against a target antigen and that the TM domain could be engineered to minimize background growth signalling.

Abstract
Since receptor tyrosine kinases (RTKs) control various cell fates in many types of cells, mimicry of RTK functions is promising for artificial control of cell fates. We have previously developed single-chain Fv (scFv)/receptor chimeras named signalobodies that can mimic receptor signaling in response to a specific antigen. While the RTK-based signalobodies enabled us to control cell growth and migration, further extension of applicability in another cell type would underlie the impact of the RTK-based signalobodies. In this study, we applied the scFv-c-Fms (S-Fms) signalobody in a murine myeloid progenitor cell line, FDC-P1. S-Fms transduced a fluorescein-conjugated BSA (BSA-FL)-dependent growth signal and activated downstream signaling molecules including MEK, ERK, Akt, and STAT3, which are major constituents of Ras/MAPK, PI3K/Akt, and JAK/STAT signaling pathways. In addition, S-Fms transduced a migration signal as demonstrated by the transwell-based migration assay. Direct real-time observation of the cells further confirmed that FDC/S-Fms cells underwent directional cell migration toward a positive gradient of BSA-FL. These results demonstrated the utility of the S-Fms signalobody for controlling growth and migration of myeloid cells. Further extension of our approach includes economical large-scale production of practically relevant blood cells as well as artificial control of cell migration for tissue regeneration and immune response.

Abstract
While many antibody-screening methods in vitro have been developed, these methods need repeated cycles of panning or sorting procedures to isolate antigen-specific antibodies. Here we developed a new antibody selection system based on antigen-dependent growth of mammalian cells. In this system, a growth signalobody library, which is a naïve single-chain Fv (scFv) library/cytokine receptor chimera that can transduce a growth signal in response to a specific antigen, is expressed in murine interleukin-3-dependent Ba/F3 cells. Simple culture of the cells in an antigen-containing medium results in growing cells with a high-affinity scFv gene, leading to selection of the scFv specific to the target antigen without panning/sorting procedures. To demonstrate this system, we used the SD1D2g signalobody having the signaling domain of gp130 and fluorescein-conjugated BSA as a target antigen, and investigated whether a fluorescein-specific scFv could be selected from a naïve scFv library. As a result, we successfully obtained fluorescein-binding scFv clones, and the scFv clone with the highest affinity was most abundantly selected, having the same sequence as the clone, which had been obtained through phage display. These results demonstrate the utility of our system as an affinity-based scFv selection method based on growth advantage of mammalian cells.

Abstract
Controlling activation levels and durations of native signaling molecules is important for efficiently controlling cellular fates. Previously we developed single-chain Fv (scFv)/cytokine receptor chimeras incorporating tyrosine motifs in the intracellular domain, which artificially control the activation of specific intracellular signaling proteins. In this study, to quantitatively control the activation levels of signaling molecules with an extended dynamic range, we constructed scFv/receptor chimeras incorporating multiple identical motifs at the different positions in the intracellular domain. We used retroviral transduction to express chimeric receptors with multiple STAT3 binding motifs connected with or without flexible linkers in a murine IL-3-dependent pro-B cell line, Ba/F3. Our results showed that the chimeric receptors can control the activation levels of STAT3 depending on ligand concentration and the number of motifs. The existence of linkers between the motifs also affected the signal intensity. Furthermore, the STAT3 activation levels significantly depended on the number of motifs rather than the distance from the JAK-binding region to the tyrosine motif.

Abstract
Conditionally and strictly controlling cell fates is important for biomedical applications including cell therapies. Although previous studies have been based on regulating the expression or activation of signaling molecules, the techniques therein require improvement in terms of reducing leakiness and complexity. In this study, we propose a novel cell fate converting system using our previously developed antibody/receptor chimeras named "signalobodies" in combination with a Cre/loxP recombination system. We designed a "switch vector" where a growth signalobody gene was flanked by two loxP sites and a death signalobody gene was placed downstream of the floxed cassette. Cells transduced with the switch vector showed superior growth activity in the presence of a specific antigen. Subsequent expression of Cre induced the death signalobody, leading to conditional cell death. This technology could be applicable for other cell fate conversion systems including differentiation and migration, by using appropriate signal-transducing domains.

Abstract
The insulin receptor (IR) is expressed ubiquitously in various tissues, where insulin exerts various biological effects on the target cells, such as cellular metabolic changes, cell proliferation and differentiation. Therefore, mimicry of insulin signaling would be a promising strategy to realize artificial control of such cellular fates. In this study, we constructed an antibody/insulin receptor chimera that enables to utilize any antigen as the ligand in principle. We constructed chimeric receptors consisting of anti-fluorescein single chain Fv (scFv), the extracellular D2 domain of erythropoietin receptor and the transmembrane/intracellular domains of IR (scFv-IR; S-IR). The function of S-IR was evaluated in terms of growth signal transduction in murine pro-B Ba/F3 cells and murine fibroblast NIH/3T3 cells. S-IR exerted IL-3-independent cell growth in Ba/F3 cells, while NIH/3T3 cells expressing S-IR acquired growth advantage over parental NIH/3T3 cells in a low-serum condition. S-IR induced phosphorylation of S-IR itself and key signaling molecules downstream of IR. Although antigen-independent activation was significantly observed, S-IR enabled specific amplification of the gene-transduced cells.

Abstract
Our understanding of the detailed mechanism of action of cytokine and growth factor receptors - and particularly our quantitative understanding of the link between structure, mechanism and function - lags significantly behind our knowledge of comparable functional protein classes such as enzymes, G protein-coupled receptors, and ion channels. In particular, it remains controversial whether such receptors are activated by a mechanism of ligand-induced oligomerization, versus a mechanism in which the ligand binds to a pre-associated receptor dimer or oligomer that becomes activated through subsequent conformational rearrangement. A major limitation to progress has been the relative paucity of methods for performing quantitative mechanistic experiments on unmodified receptors expressed at endogenous levels on live cells. In this article, we review the current state of knowledge on the activation mechanisms of cytokine and growth factor receptors, critically evaluate the evidence for and against the different proposed mechanisms, and highlight other key questions that remain unanswered. New approaches and techniques have led to rapid recent progress in this area, and the field is poised for major advances in the coming years which promise to revolutionize our understanding of this large and biologically and medically important class of receptors.

Abstract
Thrombopoietin is a potent cytokine that exerts proliferation of hematopoietic stem cells (HSCs) through its cognate receptor, c-Mpl. Therefore, mimicry of c-Mpl signaling by a receptor recognizing an artificial ligand would be attractive to attain specific expansion of genetically modified HSCs. Here we propose a system enabling selective expansion of genetically modified cells using an antibody/receptor chimera that can be activated by a specific antigen. We constructed an antibody/c-Mpl chimera, in which single-chain Fv (ScFv) of an anti-fluorescein antibody was tethered to the extracellular D2 domain of the erythropoietin receptor and transmembrane/cytoplasmic domains of c-Mpl. When the chimera was expressed in interleukin (IL)-3-dependent pro-B cell line Ba/F3, genetically modified cells were selectively expanded in the presence of fluorescein-conjugated BSA (BSA-FL) as a specific antigen. Furthermore, highly purified mouse HSCs transduced with the retrovirus carrying antibody/c-Mpl chimera gene proliferated in vitro in response to BSA-FL, and the cells retained in vivo long-term repopulating abilities. These results demonstrate that the antibody/c-Mpl chimera is capable of signal transduction that mimics wild-type c-Mpl signaling.

Abstract
Adoptive immunotherapy can induce dramatic tumor regressions in patients with melanoma or viral-induced malignancies, but extending this approach to many common cancers has been hampered by a lack of naturally occurring tumor-specific T cells. In this review, we describe recent advances in the genetic modification of T cells using genes encoding cell-surface receptors specific for tumor-associated antigen. Using genetic modification, the many functional properties of T cells, including cytokine secretion and cytolytic capacity, are redirected from their endogenous specificity toward the elimination of tumor cells. Advances in gene design, vectors, and cell production are discussed, and details of the progress in clinical application of this approach are provided.

Abstract
In this study the rainbow trout (Oncorhynchus mykiss) interleukin-2 (IL-2) cDNA has been cloned, and its expression and bioactivity analysed in head kidney leucocytes. The IL-2 precursor encoded an open reading frame of 429 bp, that translates into a predicted protein of 142 aa, with a 20 aa signal peptide. The trout IL-2 had moderate protein homology (30.9% identity/48.3% similarity) with Fugu IL-2, the only IL-2 homologue identified in fish to date, with lower homology to avian (17.8% identity/23.2% similarity) and mammalian (34.2 identity/46.5% similarity) IL-2s. IL-2 expression was induced by the T cell mitogen PHA and by the mixed leucocyte reaction, where leucocytes from pairs of fish were cultured together for four days. Expression was also induced in vivo during bacterial (Yersinia ruckeri) infection. The Escherichia coli produced recombinant IL-2 was shown to increase the expression of two transcription factors, STAT5 and Blimp-1, known to be involved in IL-2 signalling in mammals, as well as IFN-gamma, gIP and IL-2 itself. The potential signalling pathways involved and possible use as an adjuvant for fish vaccines are discussed.
