  • A Caspase-1 Biosensor to Monitor the Progression of Inflammation in Vivo
    Published October 2, 2019, doi:10.4049/jimmunol.1900619 The Journal of Immunology A Caspase-1 Biosensor to Monitor the Progression of Inflammation In Vivo Sarah Talley,* Olga Kalinina,† Michael Winek,‡ Wonbeom Paik,† Abigail R. Cannon,* Francis Alonzo, III,† Mashkoor A. Choudhry,* Katherine L. Knight,† and Edward M. Campbell*,†,‡ Inflammasomes are multiprotein complexes that coordinate cellular inflammatory responses and mediate host defense. Following recognition of pathogens and danger signals, inflammasomes assemble and recruit and activate caspase-1, the cysteine protease that cleaves numerous downstream targets, including pro–IL-1b and pro–IL-18 into their biologically active form. In this study, we sought to develop a biosensor that would allow us to monitor the initiation, progression, and resolution of inflammation in living animals. To this end, we inserted a known caspase-1 target sequence into a circularly permuted luciferase construct that becomes bioluminescent upon protease cleavage. This biosensor was activated in response to various inflammatory stimuli in human monocytic cell lines and murine bone marrow–derived macrophages. Next, we generated C57BL/6 transgenic mice constitutively expressing the caspase-1 biosensor. We were able to monitor the spatiotemporal dynamics of caspase-1 activation and onset of inflammation in individual animals in the context of a systemic bacterial infection, colitis, and acute graft-versus-host disease. These data established a model whereby the development and progression of inflammatory responses can be monitored in the context of these and other mouse models of disease.

  • Novel Microwire-Based Biosensor Probe for Simultaneous Real-Time Measurement of Glutamate and GABA Dynamics in Vitro and in Vivo
    www.nature.com/scientificreports OPEN Novel microwire‑based biosensor probe for simultaneous real‑time measurement of glutamate and GABA dynamics in vitro and in vivo P. Timothy Doughty1,4, Imran Hossain2,4, Chenggong Gong2, Kayla A. Ponder1, Sandipan Pati3, Prabhu U. Arumugam1,2* & Teresa A. Murray1* Glutamate (GLU) and γ-aminobutyric acid (GABA) are the major excitatory (E) and inhibitory (I) neurotransmitters in the brain, respectively. Dysregulation of the E/I ratio is associated with numerous neurological disorders. Enzyme‑based microelectrode array biosensors present the potential for improved biocompatibility, localized sample volumes, and much faster sampling rates over existing measurement methods. However, enzymes degrade over time. To overcome the time limitation of permanently implanted microbiosensors, we created a microwire-based biosensor that can be periodically inserted into a permanently implanted cannula. Biosensor coatings were based on our previously developed GLU and reagent-free GABA shank-type biosensor. In addition, the microwire biosensors were in the same geometric plane for the improved acquisition of signals in planar tissue including rodent brain slices, cultured cells, and brain regions with laminar structure. We measured real-time dynamics of GLU and GABA in rat hippocampal slices and observed a signifcant, nonlinear shift in the E/I ratio from excitatory to inhibitory dominance as electrical stimulation frequency increased from 10 to 140 Hz, suggesting that GABA release is a component of a homeostatic mechanism in the hippocampus to prevent excitotoxic damage. Additionally, we recorded from a freely moving rat over fourteen weeks, inserting fresh biosensors each time, thus demonstrating that the microwire biosensor overcomes the time limitation of permanently implanted biosensors and that the biosensors detect relevant changes in GLU and GABA levels that are consistent with various behaviors.

  • Current Biosensor Technologies in Drug Discovery
    Biosensor 5/7/06 12:37 Page 68 Assays Current biosensor technologies in drug discovery By Dr Matthew A. Over the past two decades the benefits of biosensor analysis have begun to Cooper make an impact in the market, and systems are beginning to be used as mainstream research tools in many laboratories1,2. Biosensors are devices that use biological or chemical receptors to detect analytes in a sample.They give detailed information on the binding affinity, and in many cases also the binding kinetics of an interaction.Typically, the receptor molecule must be connected in some way to a transducer that produces an electrical signal in real-time. Label- free biosensors do not require the use of reporter elements (fluorescent, luminescent, radiometric, or colorimetric) to facilitate measurements. Detailed information on an interaction can be obtained during analysis while minimising sample processing requirements and assay run times3. Unlike label- and reporter-based technologies that simply confirm the presence of the detector molecule, label-free techniques can provide direct information on analyte binding to target molecules typically in the form of mass addition or depletion from the surface of the sensor substrate, or measuring changes in the heat capacity of a sample4. However, these technologies have failed to gain widespread acceptance due to technical constraints, low throughput, high user expertise requirements, and cost.While they can be powerful tools in the hands of a skilled user evaluating purified samples, they are not readily adapted to every day lab use where simple to understand results on high numbers of samples are the norm.This article seeks to address some of the issues surrounding the un-met needs in the market place, and the difficulties faced by technology developers in meeting these needs with innovative products.

Unlike other reviews of this growing field, this mini-review argues that: (1) the selection of reporter genes and their regulatory proteins are directly linked to the performance of celllular biosensors; (2) broad enhancements in microelectronics and information technologies have also led to improvements in the performance of these sensors; (3) their future potential is most apparent in their use in the areas of medical diagnostics and in environmental monitoring; and (4) currently the most promising work is focused on the better integration of cellular sensors with nano and micro scaled integrated chips.
