Histone deacetylase 6's function in viral infection, innate immunity, and disease: latest advances

Area of Science:

• Molecular Biology
• Immunology
• Virology

Background:

• Histone deacetylase 6 (HDAC6) is a cytoplasmic class IIb histone deacetylase.
• HDAC6 plays a critical, yet debated, role in innate antiviral immunity.
• Understanding HDAC6's function is key to developing new antiviral strategies.

Purpose of the Study:

• To review the structure and function of HDAC6 in antiviral immunity.
• To elucidate the mechanisms by which HDAC6 controls viral infections.
• To explore the therapeutic potential of HDAC6 inhibitors.

Main Methods:

• Literature review of current research on HDAC6.
• Analysis of HDAC6's role in cytoskeleton regulation.
• Examination of HDAC6's involvement in host innate immune response and autophagy.

Main Results:

• HDAC6 regulates viral infection through cytoskeleton dynamics, immune signaling, and protein degradation via autophagy.
• HDAC6 activity is linked to the control of both DNA and RNA viruses.
• Upstream signaling pathways modulating HDAC6 activity are crucial for antiviral defense.

Conclusions:

• HDAC6 is a significant therapeutic target for antiviral immunity and innate immune responses.
• HDAC6 inhibitors offer promising avenues for treating viral diseases.
• Further research into HDAC6 signaling pathways can enhance antiviral drug development.
