Abstract
The current chapter focuses on the use of filamentous phages to display and modify biologically active cytokines, with special emphasis on directed evolution of novel variants showing improved receptor binding. Cytokines are essential protein mediators involved in cell-to-cell communication. Their functional importance and the complexity of their interactions with multichain receptors make cytokine engineering a promising tool for the discovery and optimization of therapeutic molecules. Protocols used at the laboratory are illustrated through examples of manipulation of interleukin-2 and interleukin-6, two members of the family of alpha-helix-bundle cytokines playing pivotal roles in immunity and inflammation.

Abstract
The current chapter focuses on the use of filamentous phages to display, modify, and characterize cytokines, which are proteins belonging to a versatile group of essential mediators involved in cell-cell communication. Cytokines exhibit a considerable diversity, both in functions and in structural features underlying their biological effects. A broad variety of cytokines have been successfully displayed on phages, allowing the high-throughput study of their binding properties and biological activities and the discovery of novel therapeutics through directed evolution. The technical singularities and some potential applications of cytokine phage display are illustrated here with the case of Interleukin-2, a prototypic member of the four-alpha-helix bundle cytokine family playing a pivotal role in the immune response and having a long history of therapeutic use.

Abstract
For the past 25 years, phage display technology has been an invaluable tool for studies of protein-protein interactions. However, the inherent biological, biochemical, and biophysical properties of filamentous bacteriophage, as well as the ease of its genetic manipulation, also make it an attractive platform outside the traditional phage display canon. This review will focus on the unique properties of the filamentous bacteriophage and highlight its diverse applications in current research. Particular emphases are placed on: (i) the advantages of the phage as a vaccine carrier, including its high immunogenicity, relative antigenic simplicity and ability to activate a range of immune responses, (ii) the phage's potential as a prophylactic and therapeutic agent for infectious and chronic diseases, (iii) the regularity of the virion major coat protein lattice, which enables a variety of bioconjugation and surface chemistry applications, particularly in nanomaterials, and (iv) the phage's large population sizes and fast generation times, which make it an excellent model system for directed protein evolution. Despite their ubiquity in the biosphere, metagenomics work is just beginning to explore the ecology of filamentous and non-filamentous phage, and their role in the evolution of bacterial populations. Thus, the filamentous phage represents a robust, inexpensive, and versatile microorganism whose bioengineering applications continue to expand in new directions, although its limitations in some spheres impose obstacles to its widespread adoption and use.

Abstract
A mutein with stronger antitumor activity and lower toxicity than wild-type human interleukin-2 (IL-2) has been recently described. The rationale behind its design was to reinforce the immunostimulatory potential through the introduction of four mutations that would selectively disrupt the interaction with the IL-2 receptor alpha chain (thought to be critical for both IL-2-driven expansion of T regulatory cells and IL-2-mediated toxic effects). Despite the successful results of the mutein in several tumor models, characterization of its interactions was still to be performed. The current work, based on phage display of IL-2-derived variants, showed the individual contribution of each mutation to the impairment of alpha chain binding. A more sensitive assay, based on the ability of phage-displayed IL-2 variants to induce proliferation of the IL-2-dependent CTLL-2 cell line, revealed differences between the mutated variants. The results validated the mutein design, highlighting the importance of the combined effects of the four mutations. The developed phage display-based platform is robust and sensitive, allows a fast comparative evaluation of multiple variants, and could be broadly used to engineer IL-2 and related cytokines, accelerating the development of cytokine-derived therapeutics.

Abstract
Parasite infections are largely dependent on interactions between pathogen and different host cell populations to guarantee a successful infectious process. This is particularly true for obligatory intracellular parasites as Plasmodium, Toxoplasma, and Leishmania, to name a few. Adhesion to and entry into the cell are essential steps requiring specific parasite and host cell molecules. The large amount of possible involved molecules poses additional difficulties for their identification by the classical biochemical approaches. In this respect, the search for alternative techniques should be pursued. Among them two powerful methodologies can be employed, both relying upon the construction of highly diverse combinatorial libraries of peptides or oligonucleotides that randomly bind with high affinity to targets on the cell surface and are selectively displaced by putative ligands. These are, respectively, the peptide-based phage display and the oligonucleotide-based aptamer techniques. The phage display technique has been extensively employed for the identification of novel ligands in vitro and in vivo in different areas such as cancer, vaccine development, and epitope mapping. Particularly, phage display has been employed in the investigation of pathogen–host interactions. Although this methodology has been used for some parasites with encouraging results, in trypanosomatids its use is, as yet, scanty. RNA and DNA aptamers, developed by the SELEX process (Systematic Evolution of Ligands by Exponential Enrichment), were described over two decades ago and since then contributed to a large number of structured nucleic acids for diagnostic or therapeutic purposes or for the understanding of the cell biology. Similarly to the phage display technique scarce use of the SELEX process has been used in the probing of parasite–host interaction. In this review, an overall survey on the use of both phage display and aptamer technologies in different pathogenic organisms will be discussed. Using these techniques, recent results on the interaction of Trypanosoma cruzi with the host will be highlighted focusing on members of the 85 kDa protein family, a subset of the gp85/TS superfamily.

Abstract
The incidence of autoimmunity is increasing worldwide. The long preclinical period of autoimmune disorders is characterised by an enhanced exposure over time of autoreactive T cells to an increased number of autoantigenic determinants and autoantibodies production. The discovery of novel autoimmune-disease related epitopes is a task that remains extremely challenging in order to establish predictive and preventive strategies of the disease onset. In this Opinion article we highlight the contribution of screening combinatorial random peptide libraries with patients sera in unravelling the etiopathogenesis of autoimmunity.

Abstract
INTRODUCTIONIn recent years, phage display has evolved into a powerful tool providing opportunities to define natural protein-protein interactions and to mold novel ligand receptors. The essential advantages of phage-display approaches originate in the incorporation of the protein and genetic components into a single phage particle. By providing a direct physical link between the expressed protein and the encoding genetic information, clones with desirable functional capacities can be efficiently subjected to iterative rounds of selection, followed by amplification of the selected sublibrary. Hence, during library selection (or panning), specific phage clones are progressively enriched on the basis of their specificity and affinity for ligand. Thus, relatively rare ligand-binding clones can be rescued rapidly and efficiently from large libraries. As these expression cloning systems have matured, versatile selection methods have been reported that are based on the functional properties of displayed proteins in diverse immunochemical and biological settings. This article summarizes phage-display methodology, including relevant biology, nucleotide-doping strategies, and considerations for library design.

Abstract
A nonimmune library, containing single chain variable fragments (scFv) of immunoglobulin human genes displayed on the surface of M13 filamentous phages, was used to recognize molecules exposed on Histoplasma capsulatum yeasts' surface, during their growth in synthetic medium. The scFv clones were checked in their consistency by Dot-ELISA using HRP/anti-M13 conjugate, and they were tested to recognize molecules on H. Capsulatum yeasts' surface by ELISA in plates. Three out of 80 scFv cones (C2, C6, and C52) reacted consistently with H. capsulatum molecules, and they recognized molecules from both H. capsulatum morphologic phases. However, C6 and C52 clones reacted better with molecules on the surface of whole yeasts, with molecules from the yeasts' cell-wall extract, and with molecules released to the supernatant of the yeast culture. Mycelial supernatants from other fungi, as well as from a Mycobacterium filtrate, were not recognized by scFv phage monoclones. Monoclones C2, C6, and C52 recognized yeast molecules irrespective of the H. capsulatum strains used; the C6 clone revealed a specific immunohistochemistry reaction when tested against homologous and heterologous fungal infected tissues. The scFv clones isolated will be a useful toll to define the role of their target molecules in the host-parasite relationship of histoplasmosis.

Abstract
Major histocompatibility complex (MHC) class II-dependent antigens not only activate CD4+ T helper (Th) cells, but also cytolytic T lymphocytes and effector cells of the innate immune system. These antigens therefore are candidate vaccines against cancer and infectious agents. We have developed a novel approach using a model antigen, tetanus toxoid (TT), which provides the basis for the establishment of a novel strategy of cloning Th antigens. In the TT model system, a cDNA library encoding part of the TT light chain which contained a TT-associated Th epitope recognized by TT-specific Th clones was displayed on a phage vector (TT-phage) and presented to TT-specific Th cells by autologous Epstein-Barr virus-transformed B cells (APC). These TT-phages were able to specifically activate two different TT-specific CD4+ Th cell lines as demonstrated both in [3H]thymidine incorporation and cytokine release assays. Th cell stimulation by TT-phages was significant at a ratio of one TT-phage in 50 irrelevant phages. The described approach provides the basis for the development of a novel strategy of cloning MHC class II-dependent Th antigens, using available Th cells. This strategy has several potential advantages over existing antigen cloning methods or biochemical peptide isolation.

Abstract
A cloning and expression system that allows display of proteins on the surface of filamentous phages was exploited to display a 28-kDa glutathione S-transferase (Sm28GST) antigen of the human parasite Schistosoma mansoni. The phage-displayed Sm28GST (pdGST) was immunoreactive and was recognized by immune sera, suggesting that the Sm28GST protein displayed on the surface of phages potentially maintains native conformation. Subsequent immunization studies showed that mice can develop high titers of antibodies against pdGST and do not require any additional adjuvant for immunization. Isotype analysis suggested that the pdGST immunization predominantly induced immunoglobulin G2b (IgG2b), IgG3, and IgM anti-GST antibodies in mice. Furthermore, the pdGST immunization was found to confer about 30% protection after a challenge infection with 100 cercariae of S. mansoni in BALB/c mice. These findings suggest that phage display is a simple, efficient, and promising tool to express candidate vaccine antigens for immunization against infectious agents.

Abstract
Malaria continues to kill millions of people every year and new strategies to combat this disease are urgently needed. Recent advances in the study of the mosquito vector and its interactions with the malaria parasite suggest that it may be possible to genetically manipulate the mosquito in order to reduce its vectorial capacity. Here we review the advances made to date in four areas: (1) the introduction of foreign genes into the mosquito germ line; (2) the characterization of tissue-specific promoters; (3) the identification of gene products that block development of the parasite in the mosquito; and (4) the generation of transgenic mosquitoes impaired for malaria transmission. While initial results show great promise, the problem of how to spread the blocking genes through wild mosquito populations remains to be solved.

Abstract
Phage display, which exploits fundamental tools and principles of immune repertoire diversity, antigen-antibody interactions, and clonal and immunologic selection, is used increasingly to advance experimental and clinical hematology. Phage display is based on the ability of bacteriophage to present engineered proteins on their surface coat. Diverse libraries of proteins such as peptides, antibody fragments, and protein domains corresponding to gene fragments or cDNAs may be displayed. Interactions between phage-displayed proteins and target antigens can be identified rapidly and characterized using high throughput methodologies. Peptide and gene fragment libraries are particularly useful to characterize binding interactions between proteins, such as ligand-receptor interactions. This approach allows rapid generation of human antibodies, often against nonimmunogenic, conserved proteins. Phage antibodies against surface and intracellular antigens are used as reagents for flow cytometry, in vivo imaging, and therapeutic targeting. Phage-derived antibodies also facilitate analyses of the humoral antibody response. Finally, cellular delivery of phage-displayed peptides and gene fragments can be used to modulate functional pathways and molecules in vitro and in vivo. The combinatorial power of phage display enables identification of candidate epitopes without knowledge of the protein interaction, a priori. Overall, these capabilities provide a versatile, high-throughput approach to develop tools and reagents useful for a plethora of experimental hematology applications. This paper focuses on current and future applications of antibody and epitope phage display technology in hematology.

Abstract
Myelopoietins comprise a class of chimeric cytokine receptor agonists consisting of an hIL-3 (human interleukin-3) receptor agonist and an hG-CSF (human granulocyte colony-stimulating factor) receptor agonist linked head-to-tail at their respective carboxy and amino termini. The combination of an early acting cytokine (hIL-3) with a late acting one (hG-CSF) allows efficient hematopoeitic reconstruction following myeloablative insult, and drives differentiation of non-myelocytic lineages (ie thrombocytic lineages) that are inaccessible using hG-CSF alone, in both preclinical models and clinical settings. A myelopoietin species was displayed and mutagenized on filamentous bacteriophage: both component agonists of myelopoietin were presented in biologically functional conformations as each recognized its corresponding receptor. Five amino acid positions in a short region of the hG-CSF receptor agonist module of myelopoietin that had been identified as important for proliferative activity were mutagenized. Display was used because it allows very 'deep' mutagenesis at selected residues: >10(5) substitution variants were affinity-screened using the hG-CSF receptor and 130 new, active variants of myelopoietin were identified and characterized. None of the selected variants were significantly more active than the parental myelopoietin species in a hG-CSF-dependent cell proliferation assay, though many were as active. Many of these relatively high-activity variants contained parental amino acids at several positions, suggesting the parental sequence may already be optimal at these positions for the assays used, and potentially accounting for the failure to identify enhanced bioactivity variants. Analysis of substitutions of high-activity variants complements and extends previous alanine scanning, and other genetic and biochemical data for hG-CSF variants.

Abstract
A novel system (DBDX) was developed which allows the external surface display on filamentous bacteriophage of proteins fused to either the N- or the C-terminus of a DNA-binding protein. In conjunction with helper phage infection, expression of proteins fused to the estrogen receptor DNA-binding domain (DBD) in a phagemid vector containing the DNA sequence recognized by the DBD resulted in the production of phage particles which display the fusion protein through the phage pVIII coat on the external surface of the particle. The viability of the technique was established with several model systems: particles displaying the C-terminal domain of N-cadherin or the biotinylation domain of propionyl coenzyme A carboxylase fused to the C-terminus of the DBD were found to be bound specifically by antibody or streptavidin, respectively. Human kappa constant region cDNA was selected from a N-terminal DBD fusion lymphocyte cDNA library after two rounds of selection with anti-kappa antibody. This display system may complement currently available bacterial selection techniques.

Abstract
In recent years, the use of surface-display vectors for displaying polypeptides on the surface of bacteriophage and bacteria, combined with in vitro selection technologies, has transformed the way in which we generate and manipulate ligands, such as enzymes, antibodies and peptides. Phage display is based on expressing recombinant proteins or peptides fused to a phage coat protein. Bacterial display is based on expressing recombinant proteins fused to sorting signals that direct their incorporation on the cell surface. In both systems, the genetic information encoding for the displayed molecule is physically linked to its product via the displaying particle. Using these two complementary technologies, we are now able to design repertoires of ligands from scratch and use the power of affinity selection to select those ligands having the desired (biological) properties from a large excess of irrelevant ones. With phage display, tailor-made proteins (fused peptides, antibodies, enzymes, DNA-binding proteins) may be synthesized and selected to acquire the desired catalytic properties or affinity of binding and specificity for in vitro and in vivo diagnosis, for immunotherapy of human disease or for biocatalysis. Bacterial surface display has found a range of applications in the expression of various antigenic determinants, heterologous enzymes, single-chain antibodies, and combinatorial peptide libraries. This review explains the basis of phage and bacterial surface display and discusses the contributions made by these two leading technologies to biotechnological applications. This review focuses mainly on three areas where phage and cell display have had the greatest impact, namely, antibody engineering, enzyme technology and vaccine development.

Abstract
Generation of protein immunogens is often a rate-limiting step in the production of monoclonal antibodies (Mabs). Expressing domains of proteins as fusions to the baculovirus surface glycoprotein gp64 displays foreign proteins on the surface of the virion. Antigen is produced by inserting a gene fragment in-frame between the signal sequence and the mature protein domain of the gp64 nucleotide sequence. This method allows immunization with whole virus, eliminating the need for purification of target antigens. Affinity-matured Mabs to the human nuclear receptors LXRbeta and FXR have been produced using baculovirus particles displaying gp64/nuclear receptor fusion proteins as the immunizing agent. Immunizations were performed directly with pelleted virus using the Repetitive Immunization Multiple Sites (RIMMS) immunization strategy for rapid Mab production. All Mabs were identified using insect cells infected with the immunizing virus. Characterization of these antibodies shows them to be class-switched and specific for LXRbeta or FXR. Additionally, high affinity antibodies that recognize gp64 and neutralize baculovirus infection of insect cells were isolated. Use of the recombinant baculovirus gp64 display system makes possible the production of Mabs once a partial DNA sequence is known. This allows the generation of antibodies prior to the isolation of purified protein, in turn providing antibodies to facilitate purification, characterization and immunolocalization of proteins.

The development of monoclonal antibody (mAb) technology (1) has had a significant impact on many fields of research, in particular immunology. However, the method has limitations. The use of recombinant DNA technology and demonstration by Smith 1985 (2) that peptides can be expressed on the surface of filamentous bacteriophages have permitted the development of a powerful new methodology for the generation and isolation of novel antibody-based reagents for both research and clinical application.

Abstract
The selection of phage displayed cDNA repertoires on an immobilised target has been reported to be an efficient way to rapidly identify interacting partners. To date, however, only a few successful applications have been reported. Here, we present a review of the current status of the display and selection of cDNA libraries using phage. As an example, we report the construction of a set of phage display vectors suitable for cDNA display based on fusion to the minor bacteriophage coat protein 6 (pVI) of filamentous phage. We have evaluated these vectors through the display of the C(H)3 domain of human IgG and of the Escherichia coli alkaline phosphatase (PhoA) gene. Both the C(H)3 domain of IgG and PhoA are shown to be displayed on pVI, and PhoA is also shown to be enzymatically active. We have constructed primary colorectal tumor cDNA repertoires in these vectors and performed selections on both a monoclonal antibody to beta2 microglobulin (beta2M) and polyclonal antibody sera to human IgG. In both cases, relevant ligands were recovered from the phage displayed cDNA repertoire. These vectors may be used for selection of phage displayed cDNA libraries with polyclonal sera from patients. This will allow the identifying antigenic cDNA products in such diseases as cancer, viral/bacterial infections or autoimmune disease. Furthermore, by selections with other specific biomolecules, this display system may aid the identification of interacting partners in functional genomics.

Abstract
Combinatorial peptide libraries have been playing a major role in the search for new drugs, ligands, enzyme substrates, and other specifically interacting molecules. The principal features of these libraries require a versatile repertoire, an easily identifiable tag for each of the library members, a simple method of synthesis, and a compatibility with the biochemical milieu. Two types of combinatorial libraries are in use: synthetic libraries and biological (mainly phage display) ones. An advantage of the biological libraries is due to the ability of each of the library members to replicate itself and to the fact that they carry their own coding sequences. The uniqueness of filamentous phage is that of its five virion proteins, three can tolerate the insertion of foreign peptides, each in a distinctive manner. The major coat protein, pVIII, is capable of displaying hundreds of peptide copies over the phage virion, pIII can display either one or five copies, and pVI, as opposed to the first two, displays its peptides such that the carboxy terminus is oriented outward. A major drawback of filamentous phage is its size. The length of an intact phage particle is 930 nm and it contains an ssDNA of 6400 bp. 2800 copies of the major coat protein form a "fish scale" cover over most of the virion DNA, whereas five copies of pIII, which has been the major protein used for library display, and five copies of pVI are located at one end of the filamentous virion. There is no doubt that in order to improve the quality of filamentous phage libraries, the size of phage should be drastically reduced. Comprehensive research on the phage life cycle and its structure will lead us to the construction of miniature phage and to other methods that will enable an in vivo expanding of the library repertoire as well as to binding-induced specific clone-proliferation.

Abstract
We have genetically modified filamentous bacteriophage to deliver genes to mammalian cells. In previous studies we showed that noncovalently attached fibroblast growth factor (FGF2) can target bacteriophage to COS-1 cells, resulting in receptor-mediated transduction with a reporter gene. Thus, bacteriophage, which normally lack tropism for mammalian cells, can be adapted for mammalian cell gene transfer. To determine the potential of using phage-mediated gene transfer as a novel display phage screening strategy, we transfected COS-1 cells with phage that were engineered to display FGF2 on their surface coat as a fusion to the minor coat protein, pIII. Immunoblot and ELISA analysis confirmed the presence of FGF2 on the phage coat. Significant transduction was obtained in COS-1 cells with the targeted FGF2-phage compared with the nontargeted parent phage. Specificity was demonstrated by successful inhibition of transduction in the presence of excess free FGF2. Having demonstrated mammalian cell transduction by phage displaying a known gene targeting ligand, it is now feasible to apply phage-mediated transduction as a screen for discovering novel ligands.

Abstract
Filamentous bacteriophages represent one of nature's most elegant ways of packaging and delivering DNA. In an effort to develop novel methods for ligand discovery via phage gene delivery, we conferred mammalian cell tropism to filamentous bacteriophages by attaching basic fibroblast growth factor (FGF2), transferrin, or epidermal growth factor (EGF) to their coat proteins and measuring CMV promoter-driven reporter gene expression in target cells. In this system, FGF2 was a more effective targeting agent than transferrin or EGF. The detection of green fluorescent protein (GFP) or beta-galactosidase (beta-Gal) activity in cells required FGF2 targeting and was phage concentration dependent. Specificity of the targeting for high-affinity FGF receptors was demonstrated by competing the targeted phage with FGF2, by the failure of FGF2-targeted bacteriophage to transduce high-affinity FGF receptor-negative cells, and by their ability to transduce these same cells when stably transfected with FGFR1, a high-affinity FGF receptor. Long-term transgene expression was established by selecting colonies for G418 resistance, suggesting that with the appropriate targeted tropism, filamentous bacteriophage can serve as a vehicle for targeted gene delivery to mammalian cells.

Abstract
The isolation of ligands that bind biologically relevant molecules is fundamental to the understanding of biological processes and to the search for therapeutics. Filamentous phage can be used to display foreign peptides and proteins in physical association with their DNA coding sequences. Repertoires larger than 10(8) phage clones expressing different peptide sequences can be prepared using molecular genetic techniques. The strategies utilizing this technology promise to provide not only new binding and possibly catalytic activities, but also lead structures for the development of new drugs and vaccines.

Abstract
Phage display involves the production and screening of large numbers of random peptide sequences of a specific length expressed on the surface of phage particles. This approach provides a powerful tool to probe the molecular basis of many biological processes, including host-parasite interactions. Phage display libraries have been used to study the binding specificity of numerous peptides and protein domains. Practical applications include the identification of peptide sequences that bind with high affinity to antibodies, enzymes or receptors, and that may serve as diagnostics and vaccine or drug candidates. Here, David Jefferies outlines the concept of phage display and summarizes recent developments in the field, with emphasis on those that may be of interest to parasitologists.

Abstract
In the 7 years since the first publications describing phage-displayed peptide libraries, phage display has been successfully employed in a variety of research. Innovations in vector design and methods to identify target clones account for much of this success. At the same time, not all ventures have been entirely successful and it appears that phage and host biology play important roles in this. A key issue concerns the role played by a displayed peptide or protein in its successful expression and incorporation into virions. While few studies have examined these issues specifically in context of phage display, the literature as a whole provides insight. Accordingly, we review phage biology, relevant aspects of host biology, and phage display applications with the goals of illustrating (i) relevant aspects of the interplay between phage-host biology and successful phage display and (ii) the limitations and considerable potential of this important technology.Key words: bacteriophage M13, phage display, pIII, pVIII, expression libraries.

Abstract
A phage display system for the selection of peptides binding to heterologously expressed human melanocortin receptor 1 on the surface of insect cells has been established. It could be shown that phage particles displaying the natural ligand alpha-melanocyte-stimulating hormone bind selectively to cells expressing this receptor and that these phages exhibit biological activity on mouse B16F1 melanoma cells. Insect cells were superior to other cell lines tested and have been used to select binders from a small library, in which critical determinants (Phe7-Arg8-Trp9) were kept, whereas the flanking regions where allowed to variate freely. One peptide displaying little similarity with native hormone was found that binds to the receptor also in its free form with an affinity of 7 nM. It showed a remarkable selectivity for this receptor, because it binds to the other melanocortin receptor subtypes with a maximum affinity of 21 microM. This is the first time phage display has been used successfully with G-protein-coupled receptors lacking an extracellular binding domain.

Abstract
Previous attempts to produce active human Interleukin-2 (hIL-2) in E. coli have failed, due to its aggregation in the form of cytoplasmic inclusion bodies, and the inability of the protein to enter the periplasmic export pathway, when fused to bacterial signal sequences. We have reasoned that these limitations could be overcome by introducing changes in the signal sequence and/or in some hIL-2 residues, not critical for its biological activity; and proceeded to test this hypothesis using a phagemid vector carrying the pelB secretion signal sequence, and the filamentous phage display system. Deletion of the Pro +2 in hIL-2 led to the export of a correct size (processed) molecule to the bacterial periplasm of Su- cells by the phagemid vector. However, this was achieved under growth conditions that would not favor phage assembly in Su+ strains. Changing the hydrophobic core of the leader peptide reversed this situation and allowed phage assembly and display of a pIII/hIL-2 hybrid protein in TG1 cells. The phage-displayed hIL-2 is correctly folded, as judged by its ability to interact with a conformation-specific anti-hIL-2 monoclonal antibody, and maintains its biological activity when tested in a CTLL-2 cell proliferation assay. The changes introduced in hIL-2 and the signal sequence will make possible to use the powerful phage display technology for the selection of high-affinity variants from libraries of hIL-2 mutants.

Abstract
A deletion derivative of the cytokine human interleukin-3 (hIL-3(15-125), comprising amino acids 15-125 of the native protein) was produced as a fusion to the filamentous phage surface protein pIII. The cytokine was detected in association with phage particles by protein immunoblotting. Compared to an equivalent quantity of soluble-cytokine, phage-presented hIL-3(15-125) exhibited reduced biological activity in a hIL-3-dependent cell proliferation assay. The reduction in activity was attributable to presence of phage particles in the assay, rather than directly owing to physical incorporation of the cytokine into the phage particle. Owing to the position of the amber codon in the phagemid vector, the phagemid-produced free hIL-3(15-125) species (designated hIL-3(15-125) epsilon) had 20 amino acids appended to its C-terminus; hIL-3(15-125) epsilon did not exhibit reduced bioactivity. hIL-3(15-125)-presenting phage were affinity-selected with either a hIL-3-reactive polyclonal antibody or with cells expressing the heterodimeric hIL-3 receptor. These data are consistent with the use of phage-display technology for the affinity selection of hIL-3 variants with modified biological properties.

Abstract
A procedure is described to screen panels of hybridomas or purified monoclonal antibodies using antigen displayed on the surface of filamentous bacteriophage. In this system, samples containing murine monoclonal antibodies are incubated with phage-displayed antigen in microtiter plates coated with rabbit anti-mouse IgG, and bound antibody-phage complex is detected with horseradish peroxidase-sheep anti-phage M13 conjugate. The assay has been validated with a panel of 16 monoclonal antibodies directed against human plasminogen, using phage-displayed miniplasmin-(ogen) (amino acids Ala444 through Asn791 comprising kringle 5 and the proteinase domain of plasminogen) or microplasminogen (amino acids Ala543 through Asn791 comprising the proteinase domain). Six monoclonal antibodies were identified directed against miniplasminogen and miniplasmin; this was confirmed using a microtiter plate coated with antigens. One of these monoclonal antibodies (MA-42B12) did not react with microplasminogen, suggesting that its epitope is comprised within the kringle 5 domain. This test is rapid and sensitive (detecting 10-20 ng/ml of monoclonal antibody), and screening can be performed using phage-displayed zymogens or active enzymes or selected domains thereof. The procedure eliminates the need for large amounts of purified antigen for screening. Furthermore, immunization can be performed with partially purified antigen because only antibodies raised against the antigen of interest will be identified with the use of phage-displayed antigen. Therefore, this test may offer distinct advantages over the classical one-site enzyme-linked immunosorbent assay using antigen-coated microtiter plates.

Abstract
Two low-molecular-mass forms of human plasminogen, plasminogen-(543-791)-peptide (micro-plasminogen), comprising the serine protease domain, and plasminogen-(444-791)-peptide (mini-plasminogen), which in addition contains kringle 5, were displayed on filamentous phage by fusion to the N-terminus of the minor coat protein pIII, to levels of 0.5 molecules micro-plasminogen-pIII/phage particle and 0.1 molecules mini-plasminogen-pIII/phage particle. The proenzymes, quantitatively activated by urokinase, showed catalytic efficiencies that were virtually identical to their soluble counterparts, and activity remained associated with the phage as demonstrated by phage ELISA and biopanning with human alpha2-antiplasmin or the inhibitor Phe-Pro-Arg-CH2Cl. Micro-plasminogen-pIII was activated by streptokinase and staphylokinase, two non-enzymatic plasminogen activators, to the same extent as by urokinase. Activated forms of mini-plasminogen-pIII micro-plasminogen-pIII and mini-plasminogen dissolved 125I-labelled fibrin films in a dose-dependent time-dependent manner, with 50% lysis in 20 h requiring 0.52, 3.2 and 0.46 nM active plasmin, respectively. Thus, proenzyme moieties derived from plasminogen can be successfully displayed on phage with maintenance of their enzymatic properties. The micro-plasminogen and mini-plasminogen phage-display systems may be useful to study mechanisms of plasminogen activation.

Abstract
To increase the possibilities of obtaining antibodies to surface-exposed epitopes of Pseudomonas aeruginosa protein F, we immunized mice with cloned and expressed oprF gene as a gIII-fusion protein displayed on the M13 phage surface. The fusion protein elicited mouse antibodies reacting with the purified protein F at a limit dilution of 1:10,000. Recombinant clones expressing antibody fragments were constructed from the genes of selected B cells of hyperimmunized mouse after a first round of panning against the protein F. Expression of single chain Fv (ScFv) antibody fragments to the protein of P. aeruginosa was detected by ELISA in 20 of 384 clones obtained after the first panning selection. The 20 positive clones recognizing different protein F epitopes as demonstrated by ELISA were assayed by flow cytometry to identify antibody fragments reacting only with surface-exposed epitopes of the protein F on whole bacteria; one of the 20 clones tested showed a level of reactivity compatible with surface-exposed epitope that can lead to ulterior developments in targeting studies.

Abstract
We have applied the combinatorial immunoglobulin library and phage display technologies to generate monoclonal rabbit single-chain Fv (scFv) antibody fragments specific for recombinant human leukemia inhibitory factor (rhLIF). The B cell immunoglobulin repertoire of an immunized rabbit was immortalized by the combinatorial cloning of the rearranged variable domains of light (VL) and heavy (VH) chains. Affinity selection of the library displaying the rabbit antibody domains on the phage surface resulted in the isolation of phage encoding scFv antibodies which specifically bind to the antigen. We utilized the methylotrophic yeast Pichia pastoris for high level secretion of soluble and functional scFv antibody fragment. More than 100 mg/L of pure and functional rabbit anti-rhLIF scFv antibody was obtained directly from the P. pastoris culture supernatant by one-step affinity chromatography.

Abstract
We have developed a versatile phagemid system to display peptides on the surface of M13 bacteriophage at a copy number which approaches monovalency. In this system, a phagemid encodes a peptide fused to the amino-terminus of the second domain (dII) of the minor coat protein pIII under control of the inducible lac promoter. The fusion protein is displayed in combination with several copies of wild-type pIII on the surface of phage. Two diverse random octapeptide libraries, one linear and one which contained flanking cysteines capable of forming disulfide bridges, were were generated using an in vitro mutagenesis approach and affinity selected on an anti-somatostatin mAb. Peptides with high affinity for the mAb were enriched only from the cyclic library and the tetrapeptide, FWKT, was identified by consensus as the binding epitope. The selected peptides exhibited not only the primary amino acid sequence but also shared structural features with somatostatin. One peptide, CRFWKTWC, also exhibited nanomolar affinities for the five known somatostatin receptor subtypes. This system can easily be adapted to display individual peptides or a wide range of custom peptide libraries.

Abstract
The construction of new and increasingly diverse libraries, as well as the implementation of more powerful selection schemes, has led to the identification of linear peptides that mimic complex epitopes. Phage display techniques are allowing the selection of disease-related peptides, which reproduce the antigenic and immunogenic properties of natural antigens, using whole sera from patients. The range of applications of phage technology has been extended to include the search for peptides binding to molecules other than antibodies, such as cell receptors and enzymes.

Abstract
In vitro selection from molecular libraries has rapidly come of age as a protein-engineering tool. Dramatic increases in protein affinity can be engineered using phage-display libraries, and specific antibodies can be selected directly from a single 'naïve' library of their genes. Repertoires of small molecules are a potentially valuable resource for drug discovery. Libraries of linear peptides provide ligands for proteins that recognize continuous epitopes, and low-affinity mimics of some small molecules, but generally do not contain mimics of large molecular interfaces. Switching to constrained peptide formats, and deploying more diverse, non-peptide chemical libraries, may bring greater success.
