Targeting p53 for immune modulation: Exploring its functions in tumor immunity and inflammation

Area of Science:

• Immunology
• Cell Biology
• Cancer Biology

Background:

• p53, the guardian of the genome, regulates cellular stress responses.
• p53 is a key player in tumor suppression and immune regulation.
• It orchestrates innate and adaptive immune responses, impacting pathogen clearance and immune surveillance.

Purpose of the Study:

• To review the multifaceted role of p53 in immune dynamics.
• To explore p53's influence on various immune cells (macrophages, dendritic cells, NK, T, and B cells).
• To discuss p53's implications in cancer immunotherapy, autoimmune diseases, and inflammation.

Main Methods:

• Comprehensive literature review of p53's immunological functions.
• Analysis of p53's role in immune cell interactions and signaling pathways (e.g., NF-κB).
• Exploration of high-throughput technologies (single-cell RNA sequencing, CRISPR screens) for p53 research.

Main Results:

• p53 modulates immune responses, including cytokine regulation and pattern recognition receptor activity.
• Mutations in p53 can lead to tumor immune evasion.
• p53 plays a critical role in immunogenic cell death (ICD) and antitumor immunity.

Conclusions:

• p53 is a pivotal regulator of both pro- and anti-inflammatory responses.
• Targeting p53, including wild-type p53 reactivation, shows therapeutic potential.
• Integrating p53 immunology insights is vital for novel cancer immunotherapies and personalized medicine.
