Nepravishta R, Ramirez-Cardenas J, Rocha G, Walpole S, Hicks T, Monaco S, et al.
J Med Chem . 2024 Jun; 67(12):10025-10034. PMID: 38848103
Low-affinity protein-ligand interactions are important for many biological processes, including cell communication, signal transduction, and immune responses. Structural characterization of these complexes is also critical for the development of new...

Rocha G, Ramirez-Cardenas J, Carmen Padilla-Perez M, Walpole S, Nepravishta R, Isabel Garcia-Moreno M, et al.
Anal Chem . 2024 Jan; 96(2):615-619. PMID: 38165272
STD NMR spectroscopy is a powerful ligand-observed NMR tool for screening and characterizing the interactions of small molecules and low molecular weight fragments with a given macromolecule, identifying the main...

Huettner I, Krumm S, Serna S, Brzezicka K, Monaco S, Walpole S, et al.
Cell Rep . 2022 Mar; 38(13):110611. PMID: 35354052
The HIV-1 Envelope glycoprotein (Env) is the sole target for broadly neutralizing antibodies (bnAbs). Env is heavily glycosylated with host-derived N-glycans, and many bnAbs bind to, or are dependent upon,...

Wu H, Crost E, Owen C, van Bakel W, Martinez Gascuena A, Latousakis D, et al.
PLoS Biol . 2021 Dec; 19(12):e3001498. PMID: 34936658
The human gut symbiont Ruminococcus gnavus displays strain-specific repertoires of glycoside hydrolases (GHs) contributing to its spatial location in the gut. Sequence similarity network analysis identified strain-specific differences in blood-group...

Monaco S, Walpole S, Doukani H, Nepravishta R, Martinez-Bailen M, Carmona A, et al.
Chemistry . 2020 May; 26(44):10024-10034. PMID: 32449563
Ligand-based NMR techniques to study protein-ligand interactions are potent tools in drug design. Saturation transfer difference (STD) NMR spectroscopy stands out as one of the most versatile techniques, allowing screening...

Wu H, Rebello O, Crost E, Owen C, Walpole S, Bennati-Granier C, et al.
Cell Mol Life Sci . 2020 Apr; 78(2):675-693. PMID: 32333083
The availability and repartition of fucosylated glycans within the gastrointestinal tract contributes to the adaptation of gut bacteria species to ecological niches. To access this source of nutrients, gut bacteria...

Bidula S, Cromer B, Walpole S, Angulo J, Stokes L
Sci Rep . 2019 Mar; 9(1):3231. PMID: 30824738
P2X7 receptors are important in the regulation of inflammatory responses and immune responses to intracellular pathogens such as Mycobacterium tuberculosis and Toxoplasma gondii. Enhancement of P2X7 receptor responses may be...

Dhuna K, Felgate M, Bidula S, Walpole S, Bibic L, Cromer B, et al.
Mol Pharmacol . 2018 Dec; 95(2):210-221. PMID: 30545933
We investigated the selectivity of protopanaxadiol ginsenosides from acting as positive allosteric modulators on P2X receptors. ATP-induced responses were measured in stable cell lines overexpressing human P2X4 using a YOPRO-1...
