Cell Death, by Any Other Name….

Area of Science:

• Cell Biology
• Developmental Biology
• Pathology

Background:

• Cell death research, spanning a century, continues to uncover new modes and pathways.
• Defining "cell death" remains challenging, though irreversibility is a key characteristic.
• Diverse cell death modes exhibit distinct triggering stimuli and executive final stages.

Purpose of the Study:

• To identify distinctive features of various cell death modes, focusing on their final stages.
• To examine the role of intercellular communication in cell death during development, tissue homeostasis, and disease.
• To explore therapeutic potential related to cell death and communication signaling.

Main Methods:

• Analysis of distinctive features of different cell death modes.
• Examination of intercellular communication's role through illustrative examples.
• Review of existing data on cell-cell communication in cell death propagation and therapy.

Main Results:

• Intercellular communication plays a crucial role in cell death during multicellular organism development.
• The interplay between cell death and communication is vital in rapidly renewing tissues like the gut.
• Dysregulated cell death and communication in colon tumorigenesis may relate to cancer therapy resistance.

Conclusions:

• Cell death diversity offers multiple opportunities for intercellular communication to contribute.
• Understanding cell death and communication interplay is essential for developmental biology, tissue homeostasis, and pathology.
• Targeting cell-cell communication in cell death signaling presents a potential therapeutic strategy.
