Abstract
The present study describes the development of a truncated recombinant peste des petits ruminants virus (PPRV) nucleoprotein (rPPRV-NPN) and its polyclonal antibodies-based immuno-diagnostic assay, Avidin-Biotin (AB) recombinant nucleoprotein competitive ELISA (ABrC-ELISA) for the detection of PPRV antibodies in the sheep and goats. The PPRV N-terminal immunogenic region (1-266 aa) of nucleoprotein (NPN) coding sequence was amplified and cloned into the pETite vector. The rPPRV-NPN with a molecular weight of ∼ 30 kDa was expressed in E. coli, purified, and characterized by SDS-PAGE and immunoblot using standard PPRV specific sera. The Ni-NTA affinity-purified rPPRV-NPN as coating antigen and its hyperimmune serum as competitive antibodies raised in guinea pigs were evaluated as diagnostic reagents in ABrC-ELISA using the known standard panel of sera. The threshold (cut-off) Percentage Inhibition (PI) value was determined as 45 (mean ± 3 SD) based on the reactivity of the known sheep and goats sera to PPRV antibodies [negative (n = 140) and positive (n = 98)] and the assay had a sensitivity of 97 % (95 % Confidence Interval (CI): 91.3-99.4 %) and specificity of 100 % (95 % CI: 97.4-100 %) with an excellent Area under curve (AUC) of 0.997 (95 % CI: 0.99-1.0). On evaluation of diagnostic performance of the assay using the sheep and goats sera (n = 391) from vaccinated, infected, and non-vaccinated animals, the ABrC-ELISA showed the relative diagnostic sensitivity of 95.88 % (95 % CI: 92.56-98.01 %) & 98.77 % (95 % CI: 96.43-99.74 %) and diagnostic specificity of 97.97 % (95 % CI: 94.19-99.58 %) & 90.54 % (95 % CI: 84.64-94.73 %) against indigenous PPR competitive ELISA kit & IDvet Screen® PPR Competition kit, respectively. The study showed that ABrC-ELISA is rapid, sensitive, and specific and can be a better alternative assay for the detection of the PPRV antibodies in the sera of small ruminants for serosurveillance / seromonitoring of PPR not only at the eradication and post-eradication phases in the disease-controlled endemic countries but also in the PPR non-endemic countries.

Abstract
BACKGROUND Finding a safe and effective vaccine for HIV-1 infection is still a major concern. OBJECTIVE This study aimed to design and produce a recombinant Nef-MPER V3 protein fused with IMT-P8 using E. coli expression system to provide a potential HIV vaccine with high cellular penetrance. METHODS After synthesizing the DNA sequence of the fusion protein, the construct was inserted into the pET-28 expression vector. The recombinant protein expression was induced using 1 mM IPTG and the product was purified through affinity chromatography. Characterization of cellular delivery, toxicity and immunogenicity of the protein was carried out. RESULTS The recombinant protein was expressed and confirmed by the anti-Nef antibody through western blotting. Data analyses showed that the protein possessed no considerable toxicity effect and has improved the IMT-P8 penetration rate in comparison to a control sample. Moreover, the antigen immunogenicity of the protein induced specific humoral response in mice. CONCLUSION It was concluded that IMT-P8-Nef-MPER-V3 fusion protein has a high penetrance rate in mammalian cell line and low toxicity, thus it can be potentially considered as a vaccine against HIV-1.

Abstract
Novel vaccine modalities have been designed to improve the efficiency of vaccines against HIV infections. In this way, the HIV-1 Nef protein has been known as an attractive antigenic candidate in therapeutic vaccine development. Moreover, the endogenous adjuvants such as heat shock proteins (HSPs) and high mobility group box 1 protein (HMGB1) have been suggested effectively to induce antigen-specific humoral and cellular immune responses. In this study, different Nef DNA and protein constructs were produced in eukaryotic and prokaryotic expression systems, and their immunostimulatory properties were evaluated using small heat shock protein 27 (Hsp27) and the HMGB1-derived peptide (Hp91) in a mouse model. Generally, our results indicated that the Hsp27-Nef fusion DNA or protein could significantly elicit higher humoral and cellular immune responses than Nef DNA or protein, respectively. Analysis of the immune responses demonstrated that the Hsp27-Nef fusion protein, and also the mixture of Nef and Hp91 significantly enhanced the Nef-specific T cell responses. Indeed, these regimens induced high levels of IgG2a and IFN-γ directed toward Th1 responses and also Granzyme B secretion as compared to other immunization strategies. The immunostimulatory properties of Freund's adjuvant were significantly less than Hsp27 and Hp91 peptide in various immunization strategies. These findings showed that the use of Hsp27 and Hp91 in protein strategy could improve HIV-1 Nef-specific B- and T-cell immune responses, and also represent a promising HIV-1 vaccine candidate in future.

Abstract
Hyalomma anatolicum anatolicum tick is considered as one of the main problem of ruminants' productivity in endemic countries such as parts of Africa, the Middle East and India. The disease is economically important and hence, its control and eradication is a priority. This problem reinforces the need for alternative approach like vaccine to control tick infestations instead of continuous application of acaricide which led to the natural selection of the acaricide-resistant ticks. Therefore, the present study provided evidence for the construction of transformant containing the chromosomally integrated multi-copy expression cassettes of HAO3, its successful and efficient expression in Pichia pastoris yeast and purification of the secreted protein by ultrafiltration (UF) system in a high level yield and purity. The result of antigenicity assay for the rHAO3 protein pointed well toward its capability for the elicitation of antibody response in immunized rabbits. Interestingly, the results indicated that the expressed HAO3 protein reacted well with mid gut antigen (MGAg) and rBm86 (Gavac) antisera in ELISA and western blot assays making it evident that the epitopes present in expressed protein are well recognized by the antibodies against MGAg and rBm86 proteins. Moreover, the presence of cross-reactive epitopes between rHAO3 protein with its native antigen from mid gut cells was also determined.

Abstract
Recombinant His-tagged proteins expressed in Escherichia coli and purified by immobilized metal affinity chromatography (IMAC) are commonly coeluted with native E. coli proteins, especially if the recombinant protein is expressed at a low level. The E. coli contaminants display high affinity to divalent nickel or cobalt ions, mainly due to the presence of clustered histidine residues or biologically relevant metal binding sites. To improve the final purity of expressed His-tagged protein, we engineered E. coli BL21(DE3) expression strains in which the most recurring contaminants are either expressed with an alternative tag or mutated to decrease their affinity to divalent cations. The current study presents the design, engineering, and characterization of two E. coli BL21(DE3) derivatives, NiCo21(DE3) and NiCo22(DE3), which express the endogenous proteins SlyD, Can, ArnA, and (optionally) AceE fused at their C terminus to a chitin binding domain (CBD) and the protein GlmS, with six surface histidines replaced by alanines. We show that each E. coli CBD-tagged protein remains active and can be efficiently eliminated from an IMAC elution fraction using a chitin column flowthrough step, while the modification of GlmS results in loss of affinity for nickel-containing resin. The "NiCo" strains uniquely complement existing methods for improving the purity of recombinant His-tagged protein.

Abstract
The levels of accumulation of recombinant vaccines in transgenic plants are protein specific and strongly influenced by the subcellular compartment of destination. The human immunodeficiency virus protein Nef (negative factor), a promising target for the development of an antiviral vaccine, is a cytosolic protein that accumulates to low levels in transgenic tobacco and is even more unstable when introduced into the secretory pathway, probably because of folding defects in the non-cytosolic environment. To improve Nef accumulation, a new strategy was developed to anchor the molecule to the cytosolic face of the endoplasmic reticulum (ER) membrane. For this purpose, the Nef sequence was fused to the C-terminal domain of mammalian ER cytochrome b5, a long-lived, tail-anchored (TA) protein. This consistently increased Nef accumulation by more than threefold in many independent transgenic tobacco plants. Real-time polymerase chain reaction of mRNA levels and protein pulse-chase analysis indicated that the increase was not caused by higher transcript levels but by enhanced protein stability. Subcellular fractionation and immunocytochemistry indicated that Nef-TA accumulated on the ER membrane. Over-expression of mammalian or plant ER cytochrome b5 caused the formation of stacked membrane structures, as observed previously in similar experiments performed in mammalian cells; however, Nef-TA did not alter membrane organization in tobacco cells. Finally, Nef could be removed in vitro by its tail-anchor, taking advantage of an engineered thrombin cleavage site. These results open up the way to use tail-anchors to improve foreign protein stability in the plant cytosol without perturbing cellular functions.

Abstract
Amarantin, an 11S globulin, is one of the most important storage proteins of amaranth seeds, with relevant nutritional-functional and nutraceutical characteristics. Its cDNA was cloned in-frame with a sequence encoding a polyhistidine tag and expressed under the direction of a 35S promoter in transgenic tobacco seeds. The presence of a (His)(6) tag on the polypeptide permitted a high-yield single-step purification using immobilized metal-ion affinity chromatography and rapid characterization. Purified His-tag amarantin accounted for up to 5% of total soluble seed protein. Biochemical characterization indicated that purified His-tag amarantin migrated with the expected molecular weight (53 kDa) and was correctly processed into an acidic polypeptide (32 kDa) with isoelectric point (pI) of 5.58 and a basic polypeptide (21 kDa) with pI of 9.24, linked by a disulfide bridge. Moreover, His-tag amarantin was assembled into both homo- and hetero-hexameric 11S structures. These results show that the His tag did not change the biochemical and physicochemical properties of amarantin. The strategy presented here for rapid and high-yield expression and purification procedure should facilitate structure-function studies for this nutritional protein.

Abstract
The [NiFe] centers at the active sites of the Escherichia coli hydrogenase enzymes are assembled by a team of accessory proteins that includes the products of the hyp genes. To determine whether any other proteins are involved in this process, the sequential peptide affinity system was used. The analysis of the proteins in a complex with HypB revealed the peptidyl-prolyl cis/trans-isomerase SlyD, a metal-binding protein that has not been previously linked to the hydrogenase biosynthetic pathway. The association between HypB and SlyD was confirmed by chemical cross-linking of purified proteins. Deletion of the slyD gene resulted in a marked reduction of the hydrogenase activity in cell extracts prepared from anaerobic cultures, and an in-gel assay was used to demonstrate diminished activities of both hydrogenase 1 and 2. Western analysis revealed a decrease in the final proteolytic processing of the hydrogenase 3 HycE protein, indicating that the metal center was not assembled properly. These deficiencies were all rescued by growth in medium containing excess nickel, but zinc did not have any phenotypic effect. Experiments with radioactive nickel demonstrated that less nickel accumulated in DeltaslyD cells compared with wild type, and overexpression of SlyD from an inducible promoter doubled the level of cellular nickel. These experiments demonstrate that SlyD has a role in the nickel insertion step of the hydrogenase maturation pathway, and the possible functions of SlyD are discussed.
