Talking Techniques BioTechniques

The cell-surface proteome plays a critical role in immune-cell function; however, our ability to examine its interactions and spatial organization has previously been limited by available proteomic techniques. This episode explores the function of immune-cell membrane proteins and how the latest developments in spatial proteomics have enabled more detailed interrogation of these proteins and their spatial relationships.
Our guest, Hanna van Ooijen, Immunology Application Scientist at Pixelgen Technologies guides us through the field, revealing a new technique that enables spatial analysis of the cell-surface proteome at a single-cell resolution and highlighting some exciting discoveries that it has facilitated.

In this episode of Talking Techniques, we catch up with Michael Long, Principle Investigator of the Long Lab at New York University (NY, USA), where he investigates the neural circuits that underlie vocal communication.
Through the examination of animal models, from songbirds to the rare singing mice of Costa Rica, with cutting-edge imaging techniques Michael reveals fascinating insights into vocal communication. We also discuss his human experiments, working alongside neurosurgeons, with emerging electrophysiological probes to monitor the neural activity of participants as they speak and interact, ultimately revealing how this research could begin to provide solutions for neurological conditions impacting communication, such as autism.

In this episode of Talking Techniques, we talk to Andrew Lee, a senior research fellow in Queen’s University Belfast’s (UK) wastewater-based epidemiology group, about his work using wastewater to monitor and detect infectious diseases. Andrew discusses how wastewater surveillance acts as an early warning system, providing novel, unbiased insights into human and animal pathogens that are circulating within a community, and how this can contribute to a ‘One Health’ approach. He also explains how he has incorporated nanopore sequencing into his work, and the advantages that this provides.
