Wearable sensors for human health, performance, and state monitoring, which have a linear response to the binding of biomarkers found in sweat, saliva, or urine, are of current interest for many applications. A critical part of any device is a biological recognition element (BRE) that is able to bind a biomarker at the surface of a sensor with a high affinity and selectivity to produce a measurable signal response.[...]

Extracellular nicotinate phosphoribosyltransferase binds Toll like receptor 4 and mediates inflammation

Publication year: 2019
Authors: Antonella Managò1,12, Valentina Audrito1,12, Francesca Mazzola2, Leonardo Sorci 3, Federica Gaudino1, Katiuscia Gizzi4, Nicoletta Vitale5, Danny Incarnato6, Gabriele Minazzato7, Alice Ianniello8, Antonio Varriale9, Sabato D’Auria9, Giulio Mengozzi8, Gianfranco Politano 10, Salvatore Oliviero 4,11, Nadia Raffaelli7,13 & Silvia Deaglio 1,13
Published in: Nature communications
Damage-associated molecular patterns (DAMPs) are molecules that can be actively or passively released by injured tissues and that activate the immune system. Here we show that nicotinate phosphoribosyltransferase (NAPRT), detected by antibody-mediated assays and mass spectrometry, is an extracellular ligand for Toll-like receptor 4 (TLR4) and a critical mediator of inflammation, acting as a DAMP. Exposure of human and mouse macrophages to NAPRT activates the inflammasome and NF-κB for secretion of inflammatory cytokines. [...]

Label-free lateral flow assay for Listeria monocytogenes by aptamer-gated release of signal molecules

Publication year: 2019
Authors: Tasbasi BB 1, Guner BC 1, Sudagidan M 1, Ucak S 2, Kavruk M3, Ozalp VC 4.
Published in: Analytical Biochemistry
Lateral flow assay (LFA) type of biosensors have been popular due to cost-effectiveness and easy-interpretation for instant results, most common examples of applications being pregnancy tests, food safety or medical diagnostics. There are several examples of reports with high sensitivity, including pre-concentration of the sample by magnetic pull-down. However, sensitivity and direct detection designs with aptamers has been a limiting factor for developing aptamers-based LFA assays. [...]
