Flavivirus modulation of cellular metabolism

Area of Science:

• Virology
• Cellular Metabolism
• Biochemistry

Background:

• Flaviviruses, such as Dengue and Zika viruses, are significant human pathogens.
• Viral replication necessitates significant host cell resource utilization and metabolic reprogramming.
• Understanding virus-host metabolic interactions is crucial for antiviral development.

Purpose of the Study:

• To review the mechanisms by which flaviviruses alter host cellular metabolism.
• To highlight the role of metabolic pathways in viral replication and virion production.
• To explore therapeutic opportunities targeting metabolic vulnerabilities.

Main Methods:

• Literature review of studies investigating flavivirus-induced metabolic alterations.
• Analysis of metabolic pathways including glycolysis, lipogenesis, and lipid catabolism.
• Examination of pharmacological inhibition strategies in cell culture models.

Main Results:

• Flaviviruses stimulate glycolysis and alter both lipid anabolic and catabolic pathways.
• These metabolic shifts create an energetically favorable environment for viral replication.
• Altered lipid metabolism impacts viral envelope composition and virion assembly.
• Many of these metabolic processes are druggable targets, showing antiviral potential in vitro.

Conclusions:

• Flavivirus infection profoundly impacts host cell metabolism to support viral life cycle.
• Targeting virus-induced metabolic pathways represents a promising strategy for novel antiviral drug discovery.
• Further research is needed to translate these findings into effective clinical therapies.
