The video demonstrates a method to assess caspase-mediated protein cleavage in virus-infected cells. Post-viral infection, caspases get activated and degrade various host cellular proteins and viral nucleoproteins while specific caspase inhibitors prevent this degradation, as confirmed by western blotting.

Influenza A viruses (IAVs) are important human respiratory pathogens. To understand the pathogenicity of IAVs and to perform preclinical testing of novel vaccine approaches, animal models mimicking human physiology are required. Here, we describe techniques to evaluate IAV pathogenesis, humoral responses and vaccine efficacy using a mouse model of infection.

Human infection by Entamoeba histolytica leads to amoebiasis, a major cause of diarrhea in tropical countries. Infection is initiated by pathogen interactions with intestinal epithelial cells, provoking the opening of cell-cell contacts and consequently diarrhea, sometimes followed by liver infection. This article provides a model to assess the early host-pathogen interactions to improve our understanding of amoebiasis pathogenesis.

FAQs
Following attachment to cell-surface receptors, viral particles enter the MDCK cell and replicate their genomes. Infected cells can then produce progeny virions, extending the infection to additional cells in the monolayer. These linked stages allow researchers to examine viral entry, genome replication, and production of infectious material within a controlled epithelial-cell system.
Cell-surface receptors provide the initial point of interaction between viral particles and MDCK cells. Their involvement helps determine whether attachment and entry can occur, making receptor-dependent infection relevant when comparing viral infectivity or growth. Studying this early step also separates problems with cell entry from later events such as genome replication or progeny production.
Cytopathic effects are observable changes associated with viral infection of the cell layer. Their presence can provide evidence that infection is affecting MDCK cells, while differences in the observed effects may support comparisons among viral samples or experimental conditions. Because these changes reflect cellular consequences rather than only viral presence, they complement measurements of viral growth and infectivity.
A typical workflow begins with a confluent MDCK monolayer, followed by inoculation with the virus-containing sample. The system is then used to permit the infection cycle, including attachment, entry, genome replication, and production of progeny virions. Researchers can subsequently examine infection-associated effects or use the resulting material for downstream viral and cellular analyses.
MDCK cell infection supports several related applications, including virus isolation, propagation, and titration. It can also help compare infectivity, evaluate antiviral compounds, and investigate host-cell responses. These uses make the assay valuable when researchers need a controlled epithelial-cell model for generating experimental material or assessing how viral growth changes under defined study conditions.
The experiment can provide information about viral growth, infectivity, and the cellular response to infection. Researchers may also observe cytopathic effects and use the system to obtain material for molecular or cellular studies. In biological techniques, these outcomes help connect viral replication with visible changes in host cells and with comparisons between samples or treatments.
