1Department of Microbiology, Xiangya School of Medicine, Central South University, Changsha 410078, China.
Objective:
To determine the sensitivity of mouse to human cytomegalovirus AD169 strain (HCMV AD169) infection and to establish a stable animal model for developmental disorders.
Methods:
Forty kunmin mice were divided into two groups randomly: the virus inoculated group and the control group. After 7, 15, 30, and 60 days, the mice's brain development was observed by pathological techniques. HCMV antigen was detected by immunohistochemical method and HCMV DNA was analyzed by polymerase chain reaction (PCR).
Results:
The extensive pathological damages and developmental disorders in the brain tissues of infected mice were observed. Meanwhile, the viral antigen and viral DNA were also demonstrated in the brain tissues of HCMV infected mice.
Conclusion:
HCMV can cause brain developmental disorders in mice, which provides a rationale for understanding the mechanism of congenital abnormality by HCMV infection.
Insights
Human cytomegalovirus (HCMV) infection in mice causes significant brain damage and developmental disorders. This study establishes a mouse model to investigate HCMV-induced congenital abnormalities.
Area of Science:
- Virology
- Neuroscience
- Developmental Biology
Context:
- Human cytomegalovirus (HCMV) is a significant cause of congenital abnormalities.
- Establishing reliable animal models is crucial for understanding HCMV's impact on development.
Purpose:
- To determine the sensitivity of mice to HCMV AD169 strain infection.
- To establish a stable mouse model for studying HCMV-induced developmental disorders.
Summary:
- Mice infected with HCMV AD169 exhibited extensive brain tissue damage and developmental disorders.
- HCMV antigen and DNA were detected in the brains of infected mice, confirming viral presence.
- Pathological techniques, immunohistochemistry, and PCR were used to assess viral infection and its effects.
Impact:
- This research provides a valuable animal model for investigating the mechanisms of HCMV-induced congenital abnormalities.
- Findings offer insights into how HCMV infection impacts brain development.
