Two Methods of Heterokaryon Formation to Discover HCV Restriction Factors
0 Views •
2012
We describe two methods for conditional trans-complementation of hepatitis C virus (HCV) assembly and the completion of the full viral life cycle, which rely on heterokaryon formation. These techniques are suitable to screen for cell lines that express dominant restriction factors, which preclude production of infectious HCV progeny.

Multi-modality imaging is a valuable approach for studying bacterial colonization in small animal models. This protocol outlines infection of mice with bioluminescent Citrobacter rodentium and the longitudinal monitoring of bacterial colonization using composite 3D diffuse light imaging tomography with μCT imaging to create a 4D movie of C. rodentium infection.

Source: de Vries, C. R., et al., A Delayed Inoculation Model of Chronic Pseudomonas aeruginosa Wound Infection. J. Vis. Exp. (2020).This video demonstrates a bioluminescent imaging technique to monitor bacterial infection progression in a live mouse model. Pathogenic bacteria engineered with the luxABCDE reporter system emit light at the infection site, allowing visualization of metabolically active bacteria. By imaging the mouse over time, researchers can non-invasively track infection...

Using Luciferase to Image Bacterial Infections in Mice

2011
Methods for bioluminescence imaging of bacterial infections in living animals are decribed. Pathogens are modified to express luciferase allowing optical whole body imaging of infections in live animals. Animal models can be infected with luciferase expressing pathogens and the resulting course of disease visualized in real-time by bioluminescence imaging.
FAQs
Routine imaging generally cannot display HCV particles themselves because the described approaches detect changes in liver structure or tissue mechanics rather than the virus. Consequently, interpretation focuses on indirect disease-related findings, such as altered liver architecture, increased stiffness, portal hypertension, or nodules. Virologic testing remains necessary to evaluate the infection itself.
Elastography estimates liver stiffness by sending mechanical waves through tissue and detecting the deformation they produce. The resulting stiffness measurement provides information relevant to fibrosis assessment. This adds a tissue-property measurement to the structural information supplied by ultrasound, computed tomography, or magnetic resonance imaging, supporting a broader evaluation of liver disease severity.
Ultrasound, computed tomography, and magnetic resonance imaging all contribute structural information about the liver, but they represent complementary imaging approaches rather than direct tests for HCV. Their role is to identify liver changes, complications, and nodules, while elastography adds information about tissue stiffness. The findings help characterize disease-related abnormalities from different imaging perspectives.
Imaging can support assessment of fibrosis and cirrhosis, as well as complications such as portal hypertension and liver nodules. Nodules may require particular attention because they can represent possible hepatocellular carcinoma. These findings help evaluate disease severity and complications, but imaging is interpreted alongside virologic testing and liver function measurements.
The imaging assessment is combined with virologic testing and liver function measurements rather than used as a standalone indicator of infection. Structural imaging can characterize liver abnormalities, while elastography measures stiffness associated with tissue deformation. Together, these complementary results support evaluation of disease severity and provide a noninvasive basis for clinical or research assessment.
Repeated imaging assessments can help monitor changes in liver structure, stiffness, and complications over time. This makes the approach relevant to evaluating disease progression and treatment response without relying solely on invasive assessment. In clinical research, imaging findings can be considered alongside virologic results and liver function measurements to interpret changes more completely.
