GPCR-Mediated Cell Intelligence: A Potential Mechanism for Survival and Long-Term Health.

Area of Science:

• Cellular Biology
• Molecular Signaling
• Systems Biology

Background:

• Cells exhibit dynamic capabilities including sensory, reactive, adaptive, and memory-like functions to manage lifelong stressors.
• Stress-responsive G protein-coupled receptor (GPCR) networks, linked by signaling adaptors, are crucial for cellular intelligence.
• GPCR networks and other sensory mechanisms interpret environmental cues and stressors like oxidative stress and nutrient scarcity.

Purpose of the Study:

• To underscore the presence of effective cellular intelligence supported by multi-level sensory GPCR networks.
• To highlight the role of cellular intelligence in determining somatic health and its therapeutic potential.
• To explore how cellular experiences are translated into transient and heritable memories via GPCR-induced adaptations.

Main Methods:

• Review of molecular evidence supporting cellular intelligence.
• Analysis of stress-responsive GPCR networks and signaling pathways.
• Discussion of potential future research using single-cell omics and systems biology.

Main Results:

• Cellular intelligence, mediated by GPCR networks, enables detection, processing, and retention of stressor experiences.
• Reactive (e.g., autophagy, apoptosis) and adaptive (e.g., metabolic rewiring, epigenetic modifications) responses mitigate damage and enhance survival.
• Cellular memories, potentially reliant on GPCR-induced epigenetic and mitochondrial adaptations, aid in anticipating future insults.

Conclusions:

• Cellular intelligence, underpinned by sensory GPCR networks, is a critical determinant of health.
• Dysregulation of these networks contributes to chronic diseases such as cancer, neurodegeneration, and metabolic disorders.
• Understanding cellular intelligence offers a promising frontier for therapeutic innovation in stress-induced pathologies.
