When ferroptosis meets pathogenic infections

Area of Science:

• Cellular Biology
• Immunology
• Pathogen-Host Interactions

Background:

• Regulated cell death (RCD) pathways like apoptosis, necrosis, and autophagy are crucial host defense mechanisms against pathogens.
• Pathogens can manipulate these RCDs to facilitate their replication and evade immune detection.
• Ferroptosis, a distinct form of RCD, has emerged as a significant factor in host-pathogen dynamics.

Purpose of the Study:

• To review current knowledge on the interplay between ferroptosis and pathogenic infections.
• To elucidate the mechanisms by which pathogens exploit host ferroptosis.
• To explore potential therapeutic strategies targeting ferroptosis in infectious diseases.

Main Methods:

• Literature review of studies investigating ferroptosis in the context of various pathogenic infections.
• Analysis of molecular mechanisms underlying pathogen-induced or pathogen-inhibited ferroptosis.
• Synthesis of findings to identify therapeutic targets and approaches.

Main Results:

• Pathogens actively regulate host ferroptosis to promote their own replication, dissemination, and pathogenesis.
• Specific examples illustrate how viruses, bacteria, and fungi interfere with ferroptotic pathways.
• The precise mechanisms of pathogen exploitation of ferroptosis are diverse and infection-specific.

Conclusions:

• Ferroptosis plays a critical role in the host response to and pathogen manipulation during infections.
• Targeting ferroptosis pathways offers a promising avenue for novel anti-pathogen therapies.
• Further research is needed to fully understand and therapeutically leverage ferroptosis in infectious diseases.
