Drugging the efferocytosis process: concepts and opportunities

Area of Science:

• Cell biology
• Immunology
• Homeostasis

Background:

• Efferocytosis is the daily removal of billions of apoptotic cells, crucial for maintaining bodily homeostasis.
• Phagocytes undergo rapid phenotypic changes to engulf and digest apoptotic cells during efferocytosis.
• Efferocytosis possesses anti-inflammatory properties and promotes the resolution of inflammation.

Purpose of the Study:

• To highlight the importance of efferocytosis in maintaining health.
• To discuss the link between efferocytosis dysfunction and inflammatory diseases.
• To explore the therapeutic potential of targeting efferocytosis.

Main Methods:

• This study is a review of existing literature on efferocytosis.
• It synthesizes findings on the molecular mechanisms of efferocytosis.
• It examines the role of efferocytosis in various pathologies.

Main Results:

• Aberrations in efferocytosis are implicated in inflammatory conditions such as atherosclerosis, cancer, and infections.
• Recent advances have identified key molecular players in the efferocytosis process.
• Several therapeutic agents targeting efferocytosis are currently in clinical trials.

Conclusions:

• Efferocytosis is a fundamental biological process essential for homeostasis and immune regulation.
• Dysfunctional efferocytosis represents a significant vulnerability and contributes to numerous pathologies.
• Targeting the molecular machinery of efferocytosis offers promising therapeutic strategies for inflammatory diseases.
