Entosis: the core mechanism and crosstalk with other cell death programs

Area of Science:

• Cell Biology
• Molecular Biology
• Pathophysiology

Background:

• Cell death pathways are vital for organism development, homeostasis, and disease pathogenesis.
• While diverse cell death forms are known, their physiological impacts and interplay remain incompletely understood.
• Recent findings indicate that multiple cell death types can coexist within a single cell population.

Purpose of the Study:

• To elucidate the molecular mechanisms underlying entosis, a non-apoptotic cell engulfment process.
• To discuss the signaling pathways that regulate the induction of entosis.
• To explore the potential crosstalk between entosis and other cell death mechanisms.

Main Methods:

• Literature review of entosis research.
• Analysis of molecular signaling pathways involved in cell engulfment.
• Comparative study of entosis with other programmed cell death pathways.

Main Results:

• Entosis involves the active engulfment of one cell by another, distinct from apoptosis or other known cell death forms.
• Specific signaling cascades, including Rho-ROCK and PI3K-Akt pathways, are implicated in entosis initiation and execution.
• Evidence suggests entosis can influence or be influenced by other cell death pathways, impacting overall cell fate decisions.

Conclusions:

• Entosis represents a unique cellular mechanism with significant implications for tissue dynamics and disease.
• Understanding entosis signaling is key to deciphering its role in physiological and pathological contexts.
• Further research into the crosstalk between entosis and other cell death modalities is warranted to fully grasp its biological significance.
