Seven water-soluble, tetradentate bis(3-hydroxy-N-methyl-pyridin-2-one) (bis-Me-3,2-HOPO) ligands were synthesized that vary only in linker geometry and rigidity. Solution-phase thermodynamic measurements were conducted between pH 1.6 and pH 9.0 to determine the effects of these variations on proton and uranyl cation affinity. Proton affinity decreases by introduction of the solubilizing trieth...

Helix–coil transition of complexes DNA with two ligands of different binding mechanisms to native and melted regions of biopolymer is considered using the most probable distribution method. It was shown that obtained biphasic behavior of helix–coil transition curves depends on both binding affinity and concentration of ligands in solution. Thermodynamic behavior of the ligands having higher and...

Although EGFR is a validated therapeutic target across multiple cancer indications, the often modest clinical responses to current anti-EGFR agents suggest the need for improved therapeutics. Here, we demonstrate that signal amplification driven by high-affinity EGFR ligands limits the capacity of monoclonal anti-EGFR antibodies to block pathway signaling and cell proliferation and that these l...

CD8 T cell memory critically contributes to long-term immunity. Both low-and high-affinity TCR signals are able to support the differentiation of memory CD8 T cells. However, it is unclear whether the requirements for memory development change when TCR signal strength is altered. To gain further insight into this question, we used a TCRb transmembrane domain mutant model that is defective in th...

Development of potent new anti-Shigella agents for rapid and specific detection and treatment is of great importance. Aptamers, nucleic acid oligomers capable of specific binding to a wide range of non-nucleic acid targets, may be of value for this purpose. In the present study, we used a Systematic Evolution of Ligands by Exponential enrichment (SELEX) process to select DNA aptamers that b...
