简介：
Overview
This study presents a protocol for monitoring morphological changes in human umbilical vein endothelial cells (HUVECs) during viral infection using a real-time cell analysis (RTCA) system. Through this protocol, non-invasive and continuous detection of transient effects such as cell detachment and vascular leakage is achieved, providing insights into vascular integrity.

What is the objective of the study?
To monitor changes in HUVECs during viral infection using RTCA.
What is HUVEC?
Human umbilical vein endothelial cells, a model system for studying vascular biology.
How does RTCA work?
RTCA measures electrical impedance across electrodes to monitor cell health and morphology in real time.
What were the main findings?
Significant reductions in cell index and morphological changes were observed post Zika virus infection.
Can this protocol be adapted for other cell lines?
Yes, the protocol can be adapted for other adherent cell lines under different experimental conditions.
What is the significance of continuous monitoring?
It allows for the capture of transient effects that static assays might miss.
How does this study contribute to infectious disease research?
It provides a method for assessing viral impacts on endothelial cell function, relevant to understanding vascular complications in infections.
