Summary
Human cytomegalovirus (HCMV) causes birth defects and is a threat to immunocompromised individuals. Current treatments for HCMV infections are limited by side effects and resistance.
Area of Science:
- Virology
- Immunology
- Infectious Diseases
Background:
- Human cytomegalovirus (HCMV) is a betaherpesvirus and a leading cause of congenital disabilities.
- HCMV poses significant risks to immunocompromised individuals, including transplant recipients.
- Viral replication involves a cascade of immediate-early, early, and late gene expression.
Purpose of the Study:
- To provide a comprehensive overview of Human Cytomegalovirus (HCMV).
- To discuss the pathogenesis, transmission, and clinical manifestations of HCMV.
- To review diagnostic methods and current therapeutic challenges for HCMV infections.
Main Methods:
- Review of existing literature on HCMV.
- Analysis of viral structure and replication cycle.
- Examination of clinical data regarding HCMV infection and treatment.
Main Results:
- HCMV is transmitted vertically, horizontally, and post-transplant, leading to diverse clinical outcomes.
- The virus establishes latency, with reactivation posing a threat.
- Diagnosis relies on virological, molecular, and serological methods.
Conclusions:
- HCMV infection presents significant challenges in diagnosis and treatment.
- Available antiviral drugs have limitations, including bioavailability, potency, resistance, and toxicity.
- Further research is needed to develop more effective HCMV therapies.
