Abstract
Members of the Syk family of tyrosine kinases arrange Src homology 2 (SH2) domains in tandem to allow the firm binding of immunoreceptor tyrosine-based interaction motifs (ITAMs). While the advantages provided by the bivalency enhanced interactions are evident, the impact on binding specificity is less-clear. For example, the spleen tyrosine kinase (Syk) and the ζ-chain-associated protein kinase (ZAP-70) recognize the consensus sequence pYXXI/L(X)6-8 pYXXI/L with near-identical nanomolar affinity. The nondiscriminatory recognition, on the one hand, poses a specificity challenge for the design of subtype selective protein binders and, on the other hand, raises the question as to how differential activation of Syk and ZAP-70 is ensured when both kinases are co-expressed. Herein, we identified the criteria for the design of binders that specifically address either the Syk or the Zap-70 tSH2 domain. Our approach is based on DNA-programmed spatial screening. Tyrosine-phosphorylated peptides containing the pYXXI/L motif were attached to oligonucleotides and aligned in tandem on a DNA template by means of nucleic acid hybridization. The distance between the pYXXI/L motifs and the orientation of strands were varied. The exploration exposed remarkably different recognition characteristics. While Syk tSH2 has a rather broad substrate scope, ZAP-70 tSH2 required a proximal arrangement of the phosphotyrosine ligands in defined strand orientation. The spatial screen led to the design of mutually selective, DNA-free binders, which discriminate Zap-70 and Syk tSH2 by 1 order of magnitude in affinity.

Abstract
Uropathogenic Escherichia coli infections, ultimately leading to cystitis and pyelonephritis, are initially mediated by the adhesion of the bacterial FimH to the transmembrane glycoprotein uroplakin-1a present at the surface of urothelial cells. The adhesion is based on the recognition and high avidity binding between the high-mannose glycans of the uroplakin and the FimH, a mannose-specific lectin located at the tip of type 1 fimbriae. We found that synthetic multiantennary mannopyranosides glycodendrons, harboring triazole functionality at the anomeric position, were potent hemagglutination inhibitors of guinea pig erythrocytes and E. coli. A mannosylated dendrimer exposing up to sixteen sugar residues showed an HAI titer of 1 μM and was thus 500-fold more potent than the corresponding monovalent methyl α-d-mannopyranoside. The synthesis of the glycodendrons involved highly efficient solid-phase synthesis of branched l-lysine scaffolds, diazo transfer reaction on the terminal amine residues, and 1,3-dipolar copper-catalyzed azide-alkyne cycloaddition using propargyl α-d-mannopyranoside.

Abstract
The chemokine receptor 4 (CXCR4), which is overexpressed in many types of cancer, is an emerging target in the field of molecular imaging and therapeutics. The CXCR4 binding of several peptides, including the cyclic Ac-TZ14011, has already been validated. In this study mono-, di- and tetrameric Ac-TZ14011-containing dendrimers were prepared and functionalized with a multimodal (hybrid) label, consisting of a Cy5.5-like fluorophore and a DTPA chelate. Confocal microscopy revealed that all three dendrimers were membrane bound at 4 °C, consistent with CXCR4 binding in vitro. The unlabeled dimer and tetramer had a somewhat lower affinity for CXCR4 than the unlabeled monomer. However, when labeled with the multimodal label the CXCR4 affinity of the dimer and tetramer was considerably higher compared to that of the labeled monomer. On top of that, biodistribution studies revealed that the additional peptides in the dimer and tetramer reduced nonspecific muscle uptake. Thus, multimerization of the cyclic Ac-TZ14011 peptide reduces the negative influence of the multimodal label on the receptor affinity and the biodistribution.

Abstract
Spleen tyrosine kinase (Syk) is essential for high affinity IgE receptor (FcεRI) mediated mast cell degranulation. Once FcεRI is stimulated, intracellular ITAM motifs of the receptor are diphosphorylated (dpITAM) and Syk is recruited to the receptor by binding of the Syk tandem SH2 domain to dpITAM, resulting in activation of Syk and, eventually, degranulation. To investigate intracellular effects of ITAM mimics, constructs were synthesized with ITAM mimics conjugated to different cell penetrating peptides, i.e. Tat, TP10, octa-Arg and K(Myr)KKK, or a lipophilic C(12)-chain. In most constructs the cargo and carrier were linked to each other through a disulfide bridge, which is convenient for combining different cargos with different carriers and has the advantage that the cargo and the carrier may be separated by reduction of the disulfide once it is intracellular. The ability of these ITAM constructs to label RBL-2H3 cells was assessed using flow cytometry. Fluorescence microscopy showed that the octa-Arg-SS-Flu-ITAM construct was present in various parts of the cells, although it was not homogeneously distributed. In addition, cell penetrating constructs without fluorescent labels were synthesized to examine degranulation in RBL-2H3 cells. Octa-Arg-SS-ITAM stimulated the mediator release up to 140%, indicating that ITAM mimics may have the ability to activate non-receptor bound Syk.

Abstract
Spleen tyrosine kinase (Syk) is closely related to various cell reactions. In B-cells, Syk is involved in early B-cell receptor signaling, which affects cellular survival, proliferation and differentiation. Although the kinetics of Syk mRNA and its activity are variable in different types of tumor cells, Syk may have a relation to tumor progression in many human tumors, including B-cell lymphoma/leukemia. In this study we examined whether Syk mRNA expression was changed in bovine leukemia virus (BLV)-induced persistent lymphocytosis (PL) and lymphoma. As a result, we demonstrated that the Syk mRNA expression was significantly increased in PL samples, whereas it was decreased in tumor samples. Moreover one cow, which Syk mRNA expression has been lowest among PL cattle, developed lymphoma three months later and the expression significantly decreased. These data suggest that Syk mRNA expression dynamics is closely related to BLV-induced disease.
