Article Abstract

Neuronal dense core vesicles (DCVs) store and release a diverse array of neuromodulators, trophic factors and bioamines. The analysis of single DCVs has largely been possible only using electron microscopy, which makes understanding cargo segregation and DCV heterogeneity difficult. To address these limitations, we developed genetically-encoded markers for DCVs that can be used in combination with standard immunohistochemistry and expansion microscopy, to enable single-vesicle resolution with confocal microscopy.

The rapid deployment of fifth-generation (5G) wireless networks has raised societal concerns regarding potential biological effects, particularly on human skin, due to the use of higher carrier frequencies that penetrate tissue less deeply. Consequently, whether 5G-modulated radiofrequency (RF) electromagnetic fields (EMFs) at 3.5 GHz affect oxidative stress and DNA repair in skin cells remains an open question.

Primary somatosensory neurons, glial cells in the peripheral ganglia, and neural circuits in the spinal cord function as dynamic network circuits that transmit information to the brain. Although a variety of methods and techniques have been used to study individual neurons or tissue explants, the number of neurons that can be monitored is limited. Imaging intact primary sensory neurons, such as those in the dorsal root ganglion and trigeminal ganglia, and the spinal cord in vivo using fluorescent calcium markers helps overcome the limitations of previous methods and techniques by allowing researchers to monitor tens to thousands of cells simultaneously.

Cellular processes including lysosomal and mitochondrial dysfunction are implicated in the development of many diseases. Quantitative visualization of mitochondria and lysosomes is crucial to understand how these organelles are dysregulated during disease. To address a gap in live-imaging tools, we developed GEM-SCOPe (genetically encoded and modular subcellular organelle probes), a modular toolbox of fluorescent markers designed to inform on localization, distribution, turnover, and oxidative stress of specific organelles.

Direct measurement of neural activity in freely moving animals is essential for understanding how the brain controls and represents behaviors. Genetically encoded calcium indicators report neural activity as changes in fluorescence intensity, but brain motion confounds quantitative measurement of fluorescence. Translation, rotation, and deformation of the brain and the movements of intervening scattering or autofluorescent tissue all alter the amount of fluorescent light captured by a microscope.

Replication of plant positive-strand RNA viruses occurs in association with intracellular membranes. To date, no versatile technology has been developed to directly label and visualize an active replicase in live plant cells because, in general, replicase function is not retained when it is fused to a protein for fluorescence imaging. We developed a technique to label and image a plant virus replicase during infection using the transiently expressed human influenza hemagglutinin (HA) frankenbody (FB), an antibody fragment that binds the HA epitope.
