Abstract:
Background: With an increasing understanding of the antitumor immune response, considerable
progress has been made in the field of tumor immunotherapy in the last decade. Inhibition of
histone deacetylases represents a new strategy in tumor therapy and histone deacetylase inhibitors have
been recently developed and validated as potential antitumor drugs. In addition to the direct antitumor
effects, histone deacetylase inhibitors have been found to have the ability to improve tumor recognition
by immune cells that may contribute to their antitumor activity. These immunomodolutory effects
are desirable, and their in-depth comprehension will facilitate the design of novel regimens with improved
clinical efficacy.
Objective: Our goal here is to review recent developments in the application of histone deacetylase
inhibitors as immune modulators in cancer treatment.
Methods: Systemic compilation of the relevant literature in this field.
Results & Conclusion: In this review, we summarize recent advances in the understanding of how
histone deacetylase inhibitors alter immune process and discuss their effects on various cytokines. We
also discuss the challenges to optimize the use of these inhibitors as immune modulators in cancer
treatment. Information gained from this review will be valuable to this field and may be helpful for
designing tumor immunotherapy trials involving histone deacetylase inhibitors.
