Chakrabarty et al. propose a model in which slow axonal transport of actin can occur by a biased polymerization of actin filaments along the axon shaft without the involvement of microtubules (MTs) or MT-based motors. These dynamics are distinct from

3D Printed Nasopharyngeal Swabs with Wrapped Rayon Fibers Developed and validated by SCREEN (San Diego Covid19 Research Enterprise Network) v1

Autor: Justin Ryan, Nicole Coufal, Sage Aronson, Kelsey Ladt, Catelyn Andersen, Mark Zeller, Stephen Rawlings, Denise Malicki, Gene W Yeo

The global pandemic due to SARS-CoV2 virus, also known as COVID-19, has drastically increased the need for nasopharyngeal-swab-based testing resulting in shortages of commercially available nasopharyngeal (NP) swabs. One solution to overcome the nati

Processive movement of Actin by Biased Polymerization: A new paradigm of Axonal Transport

Autor: Yinyan Tang, Subhojit Roy, Pankaj Dubey, Nilaj Chakrabarty, Christophe Leterrier, Peter Jung, Archan Ganguly, Kelsey Ladt

Classic pulse-chase studies have shown that actin is conveyed in slow axonal transport, but the mechanistic basis for this movement is unknown. Recently, we reported that axonal actin was surprisingly dynamic, with focal assembly/dis-assembly events

Axonal actin in action: Imaging actin dynamics in neurons

Autor: Kelsey, Ladt, Archan, Ganguly, Subhojit, Roy

Publikováno v: Methods Cell Biol

Actin is a highly conserved, key cytoskeletal protein involved in numerous structural and functional roles. In neurons, actin has been intensively investigated in axon terminals—growth cones—and dendritic spines, but details about actin structure

Low-light live imaging of F-actin–selective probes, quantitative tools, and super-resolution microscopy reveals a dynamic, formin-dependent deep F-actin cytoskeletal network in axons.
Although actin at neuronal growth cones is well-studied, mu

Repeated monitoring of corneal nerves by confocal microscopy as an index of peripheral neuropathy in type-1 diabetic rodents and the effects of topical insulin

Autor: Kelsey Ladt, Debbie K. Chen, Nigel A. Calcutt, Katie E. Frizzi, Andrew P. Mizisin, Lucie S. Guernsey

Publikováno v: Journal of the peripheral nervous system : JPNS, vol 18, iss 4

We developed a reliable imaging and quantitative analysis method for in vivo corneal confocal microscopy in rodents and used it to determine whether models of type-1 diabetes replicate the depletion of corneal nerves reported in diabetic patients. Qu
