Covers & Highlights

For many double stranded (ds) DNA viruses the viral genome is actively packaged into the virus capsid by a powerful molecular motor. This results in an energetically unfavorable state of the packaged genome, creating tens of atmospheres internal pressure inside the virion. Using a new calorimetric assay to determine the activation energy barriers associated with genome loss in response to elevated

Research Overview

Virus Biophysics Virus Biophysics is a rather new field that seeks to define the physical mechanisms controlling virus development. This knowledge can provide information essential to the rational design of new antiviral strategies with less specificity for a limited number of viruses. Furthermore, biological and physical simplicity relative to other biological systems have made viruses an attract

Methods and Techniques

Our Biophysical ToolsOur research group investigates mechanics of viral replication, virus-host interactions, virus assembly and disassembly within the host. Specifically, we investigate energetics, structure and mobility of the intra-capsid genome as well as mechanical properties of viral capsids, influenced by changes in physiological environment that are important for viral replication.

Atomic Force Microscopy

We use atomic force microscopy (AFM) nano-indentation method to measure DNA mobility in the capsid. The mobility of DNA packaged inside the HSV-1 capsid is measured by recording the force resisting the capsid indentation when the AFM tip is brought into contact with the DNA-filled capsid in solution. Force resisting the AFM tip indentation of the capsid is recorded as the force-distance curve. Cap

Cryo-Electron Microscopy

We use cryo electron microscopy (cryo-EM) and image reconstruction to examine the virion structure at subnanometer resolution. We also analyze structure and density of viral DNA packaged in a capsid.  Figure: Cutaway views from cryo-EM reconstructions of (A) HSV-1 C-capsid and (B) phage lambda procapsid and mature DNA-filled lambda capsid. HSV-1 and lambda phage capsids are shown to scale. Owing t

Microcalorimetry

The isothermal titration calorimetry (ITC) provides the most direct method to measure the internal energy of the confined viral genome. In order to experimentally dissect the thermodynamic determinants of viral DNA packaging and ejection energetics, we were first to use ITC to directly measure the heat released by DNA ejection from a virus capsid. This approach allows one to address experimentally

Super Resolution and Single Particle Fluorescence Microscopy

Super-Resolution Structured Illumination Microscopy (SR-SIM) provides resolutions down to 120 nm, allowing visualization of individual herpesvirus capsids (HSV-1) attached to the nucleus (HSV-1 C-capsid diameter is 125 nm).  Figure: Imaging of reconstituted capsid-nuclei system confirms specific capsid binding to the NPCs at the nuclear membrane.

Small angle X-ray scattering (SAXS) and small angle neutron scattering (SANS) of viral genomes

Despite the structure of packaged viral DNA being central for ejection and consequentially infectivity of the virus, the detailed understanding of the packing structure of DNA inside the viral capsid. SAXS and SANS allow investigation of the structure of DNA filled capsids in solution in a wide range of environmental conditions. SAXS and SANS are powerful techniques that provides detailed structur
