Abstract:
Currently, the issue relating to the discussion raised in this article appears to be for what purposes the hepatitis C virus (HCV) modulates cellular processes, such as antiviral defense, metabolism, apoptosis, and mitochondrial dynamics, by inhibiting the activity or expression of mitochondrial proteins and a number of cellular proteins. Additionally, to what pathological changes do these alterations lead? Thus, the aim of this review is to propose potential protein mitochondrial targets of HCV for the future development of new drugs aimed at inhibiting its interaction with cellular proteins. Considering current analyses in the literature, promising targets for the acute and chronic phases of HCV are proposed which include mitochondrial antiviral signaling (MAVS) (antiviral response protein), Parkin (mitophagy protein), Drp1 (mitochondrial fission protein), subunits 1 and 4 of the electron transport chain (ETC) complex (oxidative phosphorylation proteins), among others. This review illustrates how viral strategies for modulating cellular processes involving HCV proteins differ in the acute and chronic phases and, as a result, the complications that arise.
Insights
The hepatitis C virus (HCV) alters cellular functions by targeting mitochondrial proteins. This review identifies key viral targets for developing new anti-HCV drugs, differentiating acute and chronic infection strategies.
Area of Science:
- Virology
- Cell Biology
- Biochemistry
Background:
- Hepatitis C virus (HCV) infection impacts host cellular processes, including antiviral defense, metabolism, and mitochondrial dynamics.
- HCV achieves this modulation by inhibiting mitochondrial and cellular proteins, leading to pathological changes.
Purpose of the Study:
- To identify potential mitochondrial protein targets of HCV for novel drug development.
- To understand how HCV viral strategies differ between acute and chronic phases and their resulting complications.
Main Methods:
- Literature review and analysis of current research on HCV's interaction with host cellular proteins.
- Identification and proposal of specific mitochondrial targets based on their role in viral modulation.
Main Results:
- Key mitochondrial targets proposed include MAVS (antiviral response), Parkin (mitophagy), Drp1 (mitochondrial fission), and ETC complex subunits (oxidative phosphorylation).
- HCV employs distinct strategies to modulate cellular processes during acute versus chronic infection phases.
Conclusions:
- Targeting specific mitochondrial proteins offers a promising avenue for developing new therapies against HCV.
- Understanding the phase-specific viral strategies is crucial for effective therapeutic intervention against HCV complications.
