Seminar with Mechanical Engineer Assistant Professor Yun Chen @ Hodson Hall 210

Seminar with Mechanical Engineer Assistant Professor Yun Chen @ Hodson Hall 210

“The Discovery of Viscosity Sensor that Facilitates the Counterintuitive Acceleration of Migrating Cells in Highly Viscous Fluids”

Yun Chen is an assistant professor of mechanical engineering at Johns Hopkins University.  Her research is focused on developing tools to measure key parameters in mechanobiology, understanding the fundamental biophysical mechanisms that contribute to diseases, and applying knowledge gained from basic mechanobiology research to clinical applications. While a vast amount of effort has been invested in characterizing the biophysical properties in diseased cells and tissues, most of these efforts are limited to measuring the stiffness, diffusion, and viscosity of samples. Those properties are regarded as consequences of the diseases, rather than the causes. The abnormal biophysical traits can be the causes of the diseases, and her research has been dedicated to uncovering this commonly overlooked causality. Similarly, the unusual biophysical properties associated with diseases have been exploited as diagnosis tools, but few treatments, if any, employ biophysical principles to correct the errant biological processes known as pathology. Chen’s research group has been making significant progress on these uncharted territories. Their goal is to understand how altered biophysics in biological systems contribute to pathological processes in order to develop treatments for diseases. Their efforts include developing measurement tools to quantitatively characterize biophysical phenomena, such as axial stiffness of twisted DNA strands, differential force generation profiles and viscoelasticity of cancer cells compared to their normal counterparts, and identifying the underlying mechanisms for such differences, which can be exploited for disease diagnosis and treatment.

Extracellular fluid (ECF) is a critical component of the body.  Cells are surrounded by and move through biological fluids that span orders of magnitudes of viscosity in vivo, including mucus, saliva, blood, and synovial fluid, among others. Interstitial fluid in the tumor microenvironment is viscous, ascites in cancer patients is highly viscous, and the mucus of patients with cystic fibrosis is highly viscous. Elevated viscosity in the tumor microenvironment and in ascites can increase the rate of cancer cell motility and promote metastasis.  Elevated viscosity in mucus can inappropriately increase the migration of fibroblasts to airway wounds incurred in patients with cystic fibrosis, resulting in the worsening of fibrosis. Increases in ECF viscosity are also associated with aging and many other diseases.  Despite the profound implications of ECF viscosity, our understanding of the mechanosignaling pathways that allow cells to respond to viscosity changes and the underlying mechanism leading to increased cell speeds is very limited. To gain more insights, we used bio-compatible polymers to mimic viscous ECF, aims to fill this knowledge void. We conducted detailed characterization of the cellular responses to viscosity – from the time point immediately after viscosity is increased to hours afterwards, and from single molecule force measurement to dynamic 3D cellular morphology profiling. We observed that cells immersed in highly viscous medium, which had a consistency similar to that of honey, drastically changed morphology and began moving nearly twice as fast.  Step by step, we dissected the molecular cascade leading to the cell speed increase in response to elevated viscosity.  Combining numerical simulation and experimental data, we showed that membrane ruffling, a common feature of adherent cells, acts in effect as a sensor of ECF viscosity, probing the hydraulic resistance of the surrounding fluid and triggering adaptive responses. In summary, we demonstrate for the first time that a universal viscosity sensing mechanism exists in adherent cells to actively probe and adapt to changes in the viscosity of the microenvironment.  The physical interplay between mechanical forces that power membrane ruffling and the counteracting hydraulic resistance is at the heart of this sensing mechanism.

Mechanisms Governing Organ Size Dynamics in the Skin Seminar with Sashank Reddy @ Hodson Hall 305
Sep 20 @ 12:00 pm – 1:00 pm
Mechanisms Governing Organ Size Dynamics in the Skin Seminar with Sashank Reddy @ Hodson Hall 305

Uniquely among mammalian organs, skin is capable of dramatic size changes in adulthood, yet the mechanisms underlying this striking capacity are unclear. The Reddy lab recently developed a method to induce controlled skin growth in genetically tractable mice. Using machine learning-guided three dimensional tissue reconstruction, they discovered that skin growth is driven by proliferation of the epidermis in response to mechanical tension, with more limited changes in dermal and subdermal compartments. Epidermal growth is in turn achieved through preferential activation and differentiation of Lgr6+ stem cells of the epidermis, controlled in part by the Hippo pathway. Single-cell RNA sequencing uncovered further changes in mechanosensitive and metabolic pathways underlying growth control in skin. These studies point to therapeutic strategies to enhance skin growth and establish a platform for understanding organ size dynamics in adult mammals.

Those who cannot attend in person can watch on Zoom.

Johns Hopkins Translational Immunoengineering Seminar: Stephen Miller, PhD
Nov 3 @ 12:00 pm – 1:00 pm

From Bench to Bedside: Translation of a Novel PLGA Nanoparticle Delivery System for Tolerogenic Therapy of Immune-Medicated Diseases

Seminar Take-Home Points

  • Tolerance induction using antigenencapsulating PLG nanoparticles (Ag-PLG) recapitulates how self-tolerance is induced and maintained in the hematopoietic system.
  • Ag-PLG uptake by splenic marginal zone and liver APCs via the MARCO scavenger receptor confers a tolerogenic phenotype and induces activation of CD4+Foxp3+, CD4+ Tr1, andCD8+CD122+ regulatory T cells which regulate effector T cell responses in a IL-10-dependentmanner.
  • Gliadin-encapsulating PLG nanoparticles have proven efficacious in a phase 2 double-blind, placebo-controlled trial in celiac disease patients significantly reducing the gliadin-specific T cell response and preventing intestinal damage upon gluten challenge.
  • Future disease indications under clinical development include multiple sclerosis (MS),neuromyelitis optica (NMO), and peanut allergy.
