WebMar 20, 2024 · To validate whether these extracts 1–5 that exhibited NA inhibitory activity could protect host cells from influenza virus A (H1N1) infections, the CPE reduction assay was carried out in MDCK cells. The human influenza virus A/PR/8/34 (H1N1) strain was used to infect MDCK cells. Cells were incubated in the presence or absence of the … Cytopathic effect or cytopathogenic effect (abbreviated CPE) refers to structural changes in host cells that are caused by viral invasion. The infecting virus causes lysis of the host cell or when the cell dies without lysis due to an inability to replicate. Both of these effects occur due to CPEs. If a virus causes these morphological changes in the host cell, it is said to be cytopathogenic. Common examples of CPE include rounding of the infected cell, fusion with adjacent cells to form
