Abstract
Background Botulinum neurotoxin (BoNT) produced by Clostridium botulinum is one of the most potent known toxins. Moreover, BoNT is classified as one of the most important biological warfare agents that threatens the biosafety of the world. Currently, the approved treatment for botulism in humans is the use of polyvalent horse serum antitoxins. However, they are greatly limited because of insufficient supply and adverse reactions. Thus, treatment of human botulism requires the development of effective toxin-neutralizing antibodies. Considering their advantages, neutralizing nanobodies will play an increasing role as BoNTs therapeutics. Methods Herein, neutralizing nanobodies binding to the heavy chain (Hc) domain of BoNT/B (BHc) were screened from a phage display library. Then, BoNT/B-specific clones were identified and fused with the human Fc fragment (hFc) to form chimeric heavy chain antibodies. Finally, the affinity, specificity, and neutralizing activity of antibodies against BoNT/B in vivo were evaluated. Results The B5-hFc, B9-hFc and B12-hFc antibodies demonstrated high affinity for BHc in the nanomolar range. The three antibodies were proven to have potent neutralizing activity against BoNT/B in vivo. Conclusion The results demonstrate that inhibiting toxin binding to the host receptor is an efficient strategy and the three antibodies could be used as candidates for the further development of drugs to prevent and treat botulism.

Improved Production of Anti-FGF-2 Nanobody Using Pichia pastoris and Its Effect on Antiproliferation of Keratinocytes and Alleviation of Psoriasis. Arch Immunol Ther Exp (Warsz) 2023; 71:20.

Abstract
Fibroblast growth factor 2 (FGF-2) is not only an angiogenic factor, but also a mitogen for epidermal keratinocytes. FGF-2 has been shown to be positively immunoreactive in the basal layer of psoriatic lesions. In previous work, we used the Escherichia coli (E. coli) expression system to biosynthesize a biologically active anti-FGF-2 nanobody (Nb) screened by phage display technology, but the low yield limited its clinical application. In this study, we aimed to increase the yield of anti-FGF-2 Nb, and evaluate its therapeutic potential for psoriasis by inhibiting FGF-2-mediated mitogenic signaling in psoriatic epidermal keratinocytes. We demonstrated a 16-fold improvement in the yield of anti-FGF-2 Nb produced in the Pichia pastoris (P. pastoris) compared to the E. coli expression system. In vitro, the FGF-2-induced HaCaT cell model (FHCM) was established to mimic the key feature of keratinocyte overproliferation in psoriasis. Anti-FGF-2 Nb was able to effectively inhibit the proliferation and migration of FHCM. In vivo, anti-FGF-2 Nb attenuated the severity of imiquimod (IMQ)-induced psoriatic lesions in mice, and also improved the inflammatory microenvironment by inhibiting the secretion of inflammatory cytokines (IL-1β, IL-6, IL-23, and TNF-α), chemokines (CXCL1 and CCL20), and neutrophil infiltration in skin lesions. These were mainly related to the suppression of FGF-2-mediated mitogenic signaling in psoriatic keratinocytes. In conclusion, we have improved the production of anti-FGF-2 Nb and demonstrated the modality of attenuating the abnormal proliferative behavior of psoriatic keratinocytes by inhibiting FGF-2-mediated mitogenic signaling, which offers the possibility of treating psoriasis.

Abstract
NANOBODY® (a registered trademark of Ablynx N.V) molecules (Nbs), also referred to as single domain-based VHHs, are antibody fragments derived from heavy-chain only IgG antibodies found in the Camelidae family. Due to their small size, simple structure, high antigen binding affinity, and remarkable stability in extreme conditions, nanobodies possess the potential to overcome several of the limitations of conventional monoclonal antibodies. For many years, nanobodies have been of great interest in a wide variety of research fields, particularly in the diagnosis and treatment of diseases. This culminated in the approval of the world's first nanobody based drug (Caplacizumab) in 2018 with others following soon thereafter. This review will provide an overview, with examples, of (i) the structure and advantages of nanobodies compared to conventional monoclonal antibodies, (ii) methods used to generate and produce antigen-specific nanobodies, (iii) applications for diagnostics, and (iv) ongoing clinical trials for nanobody therapeutics as well as promising candidates for clinical development.

Abstract
The field of antibody development is under pressure to meet rising demands for speed, cost-effectiveness, efficacy, reliability, and large-scale production. It is costly and time-consuming to immunize animals and build a single-domain antibody (sdAb) library for each target. Using the variable domain (VHH) of heavy-chain only antibodies (HcAbs) derived from blood samples of 75 non-immunized camelid animals (51 alpacas, 13 llamas, 11 Bactrian camels), and spleens from two Bactrian camels, a naïve sdAb library with extensive megadiversity and reusability was constructed. The library was evaluated using next-generation DNA sequencing (NGS) and was found to contain hundreds of billions of unique clones. To confirm the availability of target-specific VHHs, a naive library was screened for a variety of targets. At least two VHH candidates were extracted for each target using a 20-day selection pipeline. Some binders had ultrahigh potencies, with binding affinities in the nanomolar range. This naïve library, in particular, offers the possibility of acquiring unique antibodies targeting antigens of interest with low feasible dissociation constant (kD) without the time, effort, and price associated in producing antibodies in animals via antigen injection. Overall, the study shows that the megadiverse naïve library provides a rapid, adaptable, and easy platform for antibody creation, emphasizing its therapeutic and diagnostic implications.

Abstract
Abstract
Nanobodies (Nbs) are recombinant single-domain fragments derived from camelids’ heavy-chain antibodies (HCAbs). Nanobodies are increasingly used in numerous biotechnological and medical applications because of their high stability, solubility, and yield. However, one major obstacle prohibiting Nb expansion is the affordability of specific detector antibodies for their final revelation. In this work, the production of a specific anti-Nb antibody as a general detector for camel antibodies, conventional cIgG, and HCAb, and their derived Nbs was sought. Thus, a T7 promoter plasmid was constructed and used to highly express six different Nbs that were used in a successful rabbit immunization. Affinity-purified rabbit anti-Nb rIgG was able to detect immobilized or antigen-bound Nbs via enzyme-linked immunosorbent assay, and its performance was comparable to that of a commercial anti-6× His antibody. Its capacities in dosing impure Nbs, detecting Nbs displayed on M13 phages, and revealing denatured Nbs in immune blotting were all proven. As expected, and because of shared epitopes, rabbit anti-Nb cross-reacted with cIgG, HCAbs, and 6× His-tagged proteins, and the percentage of each fraction within anti-Nb rIgG was determined. Anti-Nb is a promising tool for the checkpoints throughout the recombinant Nb technology.

Abstract
Recombinant human interferon α2b (rhIFNα2b) is widely used as an antiviral therapy agent for the treatment of hepatitis B and hepatitis C. The current identification test for rhIFNα2b is complex. In this study, an anti-rhIFNα2b nanobody was discovered and used for the development of a rapid lateral flow strip for the identification of rhIFNα2b. RhIFNα2b was used to immunize an alpaca, which established a phage nanobody library. After five steps of enrichment, the nanobody I22, which specifically bound rhIFNα2b, was isolated and inserted into the prokaryotic expression vector pET28a. After subsequent purification, the physicochemical properties of the nanobody were determined. A semiquantitative detection and rapid identification assay of rhIFNα2b was developed using this novel nanobody. To develop a rapid test, the nanobody I22 was coupled with a colloidal gold to produce lateral-flow test strips. The developed rhIFNα2b detection assay had a limit of detection of 1 μg/mL. The isolation of I22 and successful construction of a lateral-flow immunochromatographic test strip demonstrated the feasibility of performing ligand-binding assays on a lateral-flow test strip using recombinant protein products. The principle of this novel assay is generally applicable for the rapid testing of other commercial products, with a great potential for routine use in detecting counterfeit recombinant protein products.

Abstract
Single-domain antibodies (sdAbs) are binders that consist of a single immunoglobulin domain. SdAbs have gained importance as therapeutics, diagnostic reagents, and research tools. Functional sdAbs are commonly produced in Escherichia coli, which is a simple and widely used host for production of recombinant proteins. However, there are drawbacks of the E. coli expression system, including the potential for misfolded recombinant proteins and pyrogenic contamination with toxic lipopolysaccharides. Pichia pastoris is an alternative host for the production of heterologous proteins because of its high recombinant protein yields and the ability to produce soluble, properly folded proteins without lipopolysaccharide contamination. Here, we describe a method to produce sdAbs in P. pastoris. We present methods for the cloning of sdAb-encoding genes into a P. pastoris expression vector, production and purification of sdAbs, and measurement of sdAb-binding kinetics. Functional sdAbs are easily and routinely obtained using these methods.

Anti-EGFR nanobodies have been successfully applied as antitumor moieties in the photodynamic therapy and drug delivery systems. But the yields of nanobodies were still limited due to the volumetric capacity of the periplasmic compartments and inclusion bodies of Escherichia coli. A comparative study of Pichia pastoris and Escherichia coli was done through characterizing their products. Nanobody 7D12 and 7D12-9G8 were successfully expressed in Pichia pastoris with 6-13.6-fold higher yield. Both two types of nanobodies had internalization ability to be developed as antitumor moieties.

Biol Proced Online 2020; 22:25. [PMID: 33308171 PMCID: PMC7734836 DOI: 10.1186/s12575-020-00138-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Accepted: 12/01/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Ocriplasmin (Jetrea) is using for the treatment of symptomatic vitreomacular adhesion. This enzyme undergoes rapid inactivation and limited activity duration as a result of its autolytic nature after injection within the eye. Moreover, the proteolytic activity can cause photoreceptor damage, which may result in visual impairment in more serious cases. RESULTS The present research aimed to reduce the disadvantages of ocriplasmin using site-directed mutagenesis. To reduce the autolytic activity of ocriplasmin in the first variant, lysine 156 changed to glutamic acid and, in the second variant for the proteolytic activity reduction, alanine 59 mutated to threonine. The third variant contained both mutations. Expression of wild type and three mutant variants of ocriplasmin constructs were done in the Pichia pastoris expression system. The mutant variants were analyzed in silico and in vitro and compared to the wild type. The kinetic parameters of ocriplasmin variants showed both variants with K156E substitution were more resistant to autolytic degradation than wild-type. These variants also exhibited reduced Kcat and Vmax values. An increase in their Km values, leading to a decreased catalytic efficiency (the Kcat/Km ratio) of autolytic and mixed variants. Moreover, in the variant with A59T mutation, Kcat and Vmax values have reduced compared to wild type. The mix variants showed the most increase in Km value (almost 2-fold) as well as reduced enzymatic affinity to the substrate. Thus, the results indicated that combined mutations at the ocriplasmin sequence were more effective compared with single mutations. CONCLUSIONS The results indicated such variants represent valuable tools for the investigation of therapeutic strategies aiming at the non-surgical resolution of vitreomacular adhesion.

Abstract
Hemostasis is a complex process involving the concerted action of molecular and vascular components. Its basic understanding as well as diagnostic and therapeutic aspects have greatly benefited from the use of monoclonal antibodies. Interestingly, camelid-derived single-domain antibodies (sdAbs), also known as VHH or nanobodies, have become available during the previous 2 decades as alternative tools in this regard. Compared to classic antibodies, sdAbs are easier to produce and their small size facilitates their engineering and functionalization. It is not surprising, therefore, that sdAbs are increasingly used in hemostasis-related research. In addition, they have the capacity to recognize unique epitopes unavailable to full monoclonal antibodies. This property can be used to develop novel diagnostic tests identifying conformational variants of hemostatic proteins. Examples include sdAbs that bind active but not globular von Willebrand factor or free factor VIIa but not tissue factor-bound factor VIIa. Finally, sdAbs have a high therapeutic potential, exemplified by caplacizumab, a homodimeric sdAb targeting von Willebrand factor that is approved for the treatment of thrombotic thrombocytopenic purpura. In this review, the various applications of sdAbs in thrombosis and hemostasis-related research, diagnostics, and therapeutic strategies will be discussed.

Abstract
Botulinum neurotoxin (BoNT) is produced by the anaerobic, Gram-positive bacterium Clostridium botulinum. As one of the most poisonous toxins known and a potential bioterrosism agent, BoNT is characterized by a complex mode of action comprising: internalization, translocation and proteolytic cleavage of a substrate, which inhibits synaptic exocytotic transmitter release at neuro-muscular nerve endings leading to peripheral neuroparalysis of the skeletal and autonomic nervous systems. There are seven major serologically distinct toxinotypes (A-G) of BoNT which act on different substrates. Human botulism is generally caused by BoNT/A, B and E. Due to its extreme lethality and potential use as biological weapon, botulism remains a global public health concern. Vaccination against BoNT, although an effective strategy, remains undesirable due to the growing expectation around therapeutic use of BoNTs in various pathological conditions. This review focuses on the current approaches for botulism control by immunotherapy, highlighting the future challenges while the molecular underpinnings among subtypes variants and BoNT sequences found in non-clostridial species remain to be elucidated.

Abstract
PD-1/PD-L1 pathway blocking with antibodies offers a vital and efficient therapeutic strategy to restore T cell-associated antitumor immunity and treats a variety of cancers in clinic. Nanobodies (Nbs) give several advantages over conventional monoclonal antibodies such as size, solubility, stability and costs. Additionally, P. pastoris is a suitable host for Nb production. Herein, we aim to produce and evaluate anti-PD-1 Nb derived from the P. pastoris. Our findings indicated that we successfully established the Nbs phage-displayed library against PD-1 with qualified library capacity and insert ratio. Anti-PD-1 Nb Nb97 was screened through PE-ELISA and flow cytometry. To extend half-life of Nb97, we contracted pPICZɑA-Nb97-Nb97-HSA recombination vector, which was then transformed into the system of P. pastoris X-33. The yield of purified Nb97-Nb97-Human serum albumin (HSA) fused protein (MY2935) reached to 2.3 g/L after 147 h of fermentation. Meanwhile, the blocking effect of MY2935 is similar to that of MY2626 (humanized Nb97-Fc), and MY2935 showed better performance on stimulating the immune function through PD-1 reporter assay. Hence, P. pastoris X-33 expressing and secreting functional anti-PD-1 Nb-HSA fusion protein might be a system of high yield and low cost.

Abstract
Yeasts are outstanding hosts for the production of functional recombinant proteins with industrial or medical applications. Great attention has been emerged on yeast due to the inherent advantages and new developments in this host cell. For the production of each specific product, the most appropriate expression system should be identified and optimized both on the genetic and fermentation levels, considering the features of the host, vector and expression strategies. Currently, several new systems are commercially available; some of them are private and need licensing. The potential for secretory expression of heterologous proteins in yeast proposed this system as a candidate for the production of complex eukaryotic proteins. The common yeast expression hosts used for recombinant proteins' expression include Saccharomyces cerevisiae, Pichia pastoris, Hansenula polymorpha, Yarrowia lipolytica, Arxula adeninivorans, Kluyveromyces lactis, and Schizosaccharomyces pombe. This review is dedicated to discuss on significant characteristics of the most common methylotrophic and non-methylotrophic yeast expression systems with an emphasis on their advantages and new developments.

Abstract
Easy preparation of chimeric nanobodies with various scaffolds is important for customizing abilities of nanobodies toward practical utilization. To accomplish high-throughput production of various nanobodies, utilization of microbes is an attractive option. In the present study, various chimeric nanobodies were prepared using the methylotrophic yeast Pichia pastoris. We designed chimeric nanobodies with complementarity-determining regions (CDRs) against green fluorescent protein (GFP) or cluster of differentiation 4 (CD4) based on the scaffold of GFP-nanobody. FLAG-tagged chimeric nanobodies were prepared by one-step cloning and produced using P. pastoris. Secreted chimeric nanobodies were purified from the culture media of P. pastoris transformants. Relative binding abilities of purified chimeric nanobodies to GFP and CD4 was tested using a BIACORE T-200. P. pastoris successfully produced a high yield of FLAG-tagged chimeric nanobodies. FLAG-tagged GFP- and CD4-nanobodies were shown to specifically bind to GFP and CD4, respectively. Chimeric nanobodies, in which the CDR2 or 3 of GFP-nanobody was replaced with CDRs of CD4-nanobody, acquired the ability to bind to CD4 without binding to GFP. These results demonstrate successful production of functional chimeric nanobodies using P. pastoris. These results also suggest that swapping of CDRs, especially CDRs 2 or 3, potentially enables a novel method of creating nanobodies.

Abstract
Nanobodies offer multiple advantages over conventional antibodies in terms of size, stability, solubility, immunogenicity, and production costs, with improved tumor uptake and blood clearance. Additionally, the recombinant expression of nanobodies is robust in various expression systems, such as Escherichia coli, Saccharomyces cerevisiae and Pichia pastoris. P. pastoris is the most widely used microorganism for nanobody production, but all or almost all expression vectors developed for this system are based on the regulated promoter of the alcohol oxidase 1 gene (AOX1) that requires methanol for full induction. In this study, a constitutive anti-CEACAM5 nanobody expression system was constructed under the control of a glyceraldehyde-3-phosphate dehydrogenase promoter (GAP) promoter. The effects of different carbon sources and pH on nanobody expression were evaluated in shaking flask cultures. After 96 h of constitutive expression in shaking flask, a yield of 51.71 mg/L was obtained. In addition, this constitutive expression system produced nanobodies at equivalent yield and affinity to that produced by methanol-induced expression. The results of this study indicated that the use of a constitutive expression system is a promising alternative for the production of nanobodies applied for cancer diagnosis and therapy.

Abstract
BACKGROUND An effective therapy against envenoming should be a priority in view of the high number scorpion stings and snakebites. Serum therapy is still widely applied to treat the envenomation victims; however this approach suffers from several shortcomings. The employment of monoclonal antibodies might be an outcome as these molecules are at the core of a variety of applications from protein structure determination to cancer treatment. The progress of activities in the twilight zone between genetic and antibody engineering have led to the development of a unique class of antibody fragments. These molecules possess several benefits and lack many possible disadvantages over classical antibodies. Within recombinant antibody formats, nanobodies or single domain antigen binding fragments derived from heavy chain only antibodies in camelids occupy a privileged position. SCOPE OF REVIEW In this paper we will briefly review the common methods of envenomation treatment and focus on details of various in vivo research activities that investigate the performance of recombinant, monoclonal nanobodies in venom neutralization. MAJOR CONCLUSIONS Nanobodies bind to their cognate target with high specificity and affinity, they can be produced in large quantities from microbial expression systems and are very robust even when challenged with harsh environmental conditions. Upon administering, they rapidly distribute throughout the body and seem to be well tolerated in humans posing low immunogenicity. GENERAL SIGNIFICANCE Scorpion and snake envenomation is a major issue in developing countries and nanobodies as a venom-neutralizing agent can be considered as a valuable and promising candidate in envenomation therapy.

Abstract
Nanobodies represent the next-generation antibody-derived biologics with significant advances over conventional antibodies. Several rapid and robust techniques for isolating highly specific nanobodies have been developed. Antigen specific nanobodies are selected from constructed nanobody libraries, which can be classified into 3 main types: immune library, naïve library, and semisynthetic/synthetic library. The immune library is the most widely used strategy for nanobody screening. Target specific nanobodies are highly enriched in immune libraries than in non-immune libraries; however, it is largely limited by the natural antigenicity of antigens. The naïve library is thus developed. Despite the lack of somatic maturation, protein engineering can be employed to significantly increase the affinities of selected binders. However, a substantial amount of blood samples collected from a large number of individual animals is a prerequisite to ensure the diversity of the naïve library. With this issue considered, the semisynthetic/synthetic library may be a promising path toward obtaining a limitless source of nanobodies against a variety of antigens without the need of animals. In this review, we summarize the state-of-the-art screening technologies with different libraries. The approaches presented here can further boost the diverse applications of nanobodies in biomedicine and biotechnology.

Abstract
Background: Colorectal cancer is the third most common type of aggressive cancers. Chemotherapy, surgery, and radiotherapy are the common therapeutic options for treating this cancer. Due to the adverse side-effects of these methods, immunotherapy is considered as an appropriate alternative therapeutic option. Treatment through the application of monoclonal antibodies is considered as a novel alternative therapeutic method for cancers. The variable fragments of the antibodies' heavy chain or VHHs have a wide application in molecular biology and biotechnology. VHHs are compatible with the phage display technology which allows rapid and high throughput screening for antibodies isolation. Objectives: We aimed to use naive VHH phage library to isolate a specific nanobody against colorectal tumor associated antigen; the AgSK1. Materials and Methods: In this research, naive VHH phage library was panned against two colorectal cell lines; Ls174T and HT29 expressing different levels of AgSK1 tumor associated marker. The high affinity binders were selected and subcloned for higher expression levels of the VHH. The affinity and specificity of the isolated VHH were tested using ELISA. The reactivity of the VHH toward cancer cells was analyzed by competitive ELISA applying sera isolated from colorectal cancer patients. Results: Results show that the isolated VHH recognizes and binds to the colorectal cancer cells with a high affinity. Moreover, the isolated nanobody is able to compete with the antibodies in the patient sera for the binding to the cancer cells. Conclusions: Results suggest that this nanobody has a specific reaction toward colorectal cells and can be used for further investigation on the tumor associated antigens or production of mimotopes useful for immunotherapy.

Abstract
Background Recombinant antibodies are highly successful in many different pathological conditions and currently enjoy overwhelming recognition of their potential. There are a wide variety of protein expression systems available, but almost all therapeutic antibodies are produced in mammalian cell lines, which mimic human glycosylation. The production of clinical-grade antibodies in mammalian cells is, however, extremely expensive. Compared to mammalian systems, protein production in yeast strains such as Pichia pastoris, is simpler, faster and usually results in higher yields. Results In this work, a trivalent single-chain fragment variable (scFv)-based N-terminal trimerbody, specific for the human carcinoembryonic antigen (CEA), was expressed in human embryonic kidney 293 cells and in Pichia pastoris. Mammalian- and yeast-produced anti-CEA trimerbody molecules display similar functional and structural properties, yet, the yield of trimerbody expressed in P. pastoris is about 20-fold higher than in human cells. Conclusions P. pastoris is an efficient expression system for multivalent trimerbody molecules, suitable for their commercial production.
