Abstract
Anionic boron clusters can be used to increase the pharmaceutical properties of the peptides. Here, we describe the method of synthesis of peptide/protein-boron cluster conjugates using solid-state, thermal reaction on two different peptides: thymosin β4 (Tβ4) and lysozyme. 1,4-dioxane oxonium derivatives of anionic boron clusters are used as donors of boron clusters. This procedure allows to conjugate anionic boron clusters to native peptides without loss of the activity of the peptides.

Abstract
Recently a great interest in the field of protein engineering and the design of innovative drug delivery systems employing specific ligands such as cyclodextrins is observed. The paper reports the solid state, thermal method for protein coupling with β-cyclodextrin and the physicochemical and biological properties of the obtained conjugates. The structure of the obtained conjugates was investigated via liquid chromatography-mass spectrometry, dynamic light scattering and circular dichroism analysis. The presented conjugates were biologically active and covalently bound β-cyclodextrin preserved the ability to form inclusion complexes with the model compound. This report demonstrates the great potential of cyclodextrin as a modifying unit that can be used to modulate the properties of therapeutic proteins, additionally giving such conjugates the possibility to transport many therapeutic substances in the form of inclusion complexes. In addition, the paper presents the potential of protein-cyclodextrin conjugates to construct innovative bioactive molecules for biological and medical applications.

Abstract
Two complementary methods, "in solution" and "in solid state", for the synthesis of lysozyme modified with metallacarborane (cobalt bis(dicarbollide), Co(C2 B9 H11 )2 (2-) ) were developed. As metallacarborane donors, oxonium adducts of cobalt bis(dicarbollide) and 1,4-dioxane or tetrahydropyran were used. The physicochemical and biochemical properties of the obtained lysozyme-metallacarborane conjugates were studied for changes in secondary and tertiary structure, aggregation behavior, and biological activity. Only minor changes in primary, secondary, and tertiary protein structure were observed, caused by the single substitution of metallacarborane on lysozyme. However, the modification produced significant changes in lysozyme enzymatic activity and a tendency toward time- and temperature-dependent aggregation.

Abstract
BACKGROUND Boron clusters represent a vast family of boron-rich compounds with extraordinary properties that provide the opportunity of exploitation in different areas of chemistry and biology. In addition, boron clusters are clinically used in boron neutron capture therapy (BNCT) of tumors. In this paper, a novel, in solid state (solvent free), thermal method for protein modification with boron clusters has been proposed. METHODS The method is based on a cyclic ether ring opening in oxonium adduct of cyclic ether and a boron cluster with nucleophilic centers of the protein. Lysozyme was used as the model protein, and the physicochemical and biological properties of the obtained conjugates were characterized. RESULTS The main residues of modification were identified as arginine-128 and threonine-51. No significant changes in the secondary or tertiary structures of the protein after tethering of the boron cluster were found using mass spectrometry and circular dichroism measurements. However, some changes in the intermolecular interactions and hydrodynamic and catalytic properties were observed. CONCLUSIONS To the best of our knowledge, we have described the first example of an application of cyclic ether ring opening in the oxonium adducts of a boron cluster for protein modification. In addition, a distinctive feature of the proposed approach is performing the reaction in solid state and at elevated temperature. GENERAL SIGNIFICANCE The proposed methodology provides a new route to protein modification with boron clusters and extends the range of innovative molecules available for biological and medical testing.

Abstract
SCOPE Glycation of allergens via Maillard reaction or chemical conjugation has been shown to influence susceptibility to food-induced allergies. It is hypothesized that mucosal immune response bias can be favorably altered by orally administering various forms of glycated ovalbumin (OVA). METHODS AND RESULTS Groups of Balb/c mice (n = 10) were orally sensitized to OVA and administered various forms of glycated OVA (glucose, mannose, glucomannan, galactomannan, and a mixture containing OVA and glucomannan). Outcomes post oral challenge were measured as clinical allergic signs, serum histamine, mouse mast cell protease 1 (MMCP-1), antibody activity, type-1/2 cytokines, percentage of T-regulatory cells (T-regs) and in vitro dendritic cell, and T-cell-related mechanisms. Clinical signs and specific IgE were decreased (p ≤ 0.05), and T-reg cell percentage was increased in the mannose and glucomannan treated groups. The OVA-mannose group also had less histamine, MMCP-1, specific IgG, IL-4 and IL-17, and more IL-12p70 (p ≤ 0.05). Other parameters measured did not differ significantly among groups. Also, OVA-glycated mannose reduced maturation and uptake by dendritic cells. Less activation of T cells and type-2 cytokine response in DC-T-cell cocultures were observed with OVA-glycated mannose stimulation. CONCLUSION This study validates, for the first time, the use of OVA-glycated mannose and glucomannan for potential beneficial dietary interventions for allergy.

FimH adhesin from host unrestricted Salmonella Enteritidis binds to different glycoprotein ligands expressed by enterocytes from sheep, pig and cattle than FimH adhesins from host restricted Salmonella Abortus-ovis, Salmonella Choleraesuis and Salmonella Dublin. Vet Microbiol 2013; 166:550-7.

Abstract
Adhesion to gut tissues and colonization of the alimentary tract, two important stages in the pathogenesis of Salmonella, are mediated by FimH adhesin of type 1 fimbriae. It was suggested that minor differences in the structure of FimH are most likely associated with differences in adhesion specificities, and may determine the tropism of various Salmonella serovars to different species and tissues. We investigated this hypothesis by comparing the binding properties of FimH proteins from three Salmonella enterica serovars with limited (Choleraesuis, Dublin) or restricted (Abortusovis) host ranges to FimH from broad host range S. Enteritidis and mannose inactive FimH from S. Gallinarum. Although all active variants of FimH protein were able to bind mannose-rich glycoproteins (RNase B, HRP and Man-BSA) with comparable affinity measured by surface plasmon resonance, there were significant differences in the binding profiles of the FimH proteins from host restricted serovars and host unrestricted serovar Enteritidis, to glycoproteins from enterocyte cell lines established in vitro and derived from sheep, pig and cattle. When low-binding FimH adhesin from S. Enteritidis was subjected to Western blot analysis, it bound to surface membrane protein of about 130 kDa, and high-binding FimH adhesins from S. Abortusovis, S. Choleraesuis and S. Dublin bound to surface membrane protein of about 55 kDa present in each cell line. Differential binding of FimH proteins from host-restricted and broad-host-range Salmonella to intestinal receptors was confirmed using mutant FimH adhesins obtained by site-directed mutagenesis. It was found that the low-binding variant of FimH from S. Choleraesuis with mutation Leu57Pro lost the ability to bind protein band of 55 kDa, but instead interacted with glycoprotein of about 130 kDa. On the other hand, the high-binding variant of FimH adhesin from S. Enteritids with mutation Asn101Ser did not bind to its receptor of 130 kDa, but instead it interacted with glycoprotein ligand of 55 kDa. These results suggest that FimH adhesins of type 1 fimbriae are one of the factors responsible for different host-specificities of these Salmonella serovars.

Abstract
The binding properties of low- and high-adhesive forms of FimH adhesins from Salmonella enterica serovars Enteritidis and Typhimurium (S. Enteritidis and S. Typhimurium) were studied using chimeric proteins containing an additional peptide that represents an N-terminal extension of the FimF protein. This modification, by taking advantage of a donor strand exchange mechanism, closes the hydrophobic groove in the fimbrial domain of the FimH adhesin. Such self-complemented adhesins (scFimH) did not form aggregates and were more stable (resistant to proteolytic cleavage) than native FimH. High-adhesive variants of scFimH proteins, with alanine at position 61 and serine at position 118, were obtained by site-directed mutagenesis of fimH genes from low-adhesive variants of S. Enteritidis and S. Typhimurium, with glycine at position 61 and phenylalanine at position 118. Direct kinetic analysis using surface plasmon resonance (SPR) and glycoproteins carrying high-mannose carbohydrate chains (RNase B, horseradish peroxidase and mannan-BSA) revealed the existence of high- and low-adhesive allelic variants, not only in S. Typhimurium but also in S. Enteritidis. Using two additional mutants of low-adhesive FimH protein from S. Enteritidis (Gly61Ala and Phe118Ser), SPR analysis pointed to Ser118 as the major determinant of the high-adhesive phenotype of type 1 fimbriae from S. Enteritidis. These studies demonstrated for the first time that the functional differences observed with whole fimbriated bacteria could be reproduced at the level of purified adhesin. They strongly suggest that the adhesive properties of type 1 fimbriae are determined only by structural differences in the FimH proteins and are not influenced by the fimbrial shaft on which the adhesin is located.
