Rhythmicity and waves in the cortex of single cells

Area of Science:

• Cell Biology
• Systems Biology
• Biophysics

Background:

• Dynamic patterns, including oscillations and waves, emerge on the cortex of single cells.
• Understanding these patterns is crucial for deciphering cellular organization and function.
• Current understanding often relies on observational descriptions rather than mechanistic explanations.

Purpose of the Study:

• To outline theoretical frameworks for modeling single-cell dynamic patterns.
• To review recent progress in quantitatively and molecularly defining these patterns.
• To shift the study of cellular dynamics from descriptive to mechanistic.

Main Methods:

• Review of theoretical frameworks for pattern formation modeling.
• Analysis of spatial couplings and the role of the active membrane in wave propagation.
• Focus on excitable and oscillation events within cellular dynamics.

Main Results:

• Theoretical frameworks can reduce complex cellular patterns into biologically tractable parameters.
• Progress has been made in defining dynamic patterns quantitatively and molecularly.
• Cellular patterns can be viewed as basic properties of dynamic systems.

Conclusions:

• Mechanistic studies of single-cell dynamic patterns are transforming the field.
• Knowledge of these patterns can dissect cellular organization and define functions.
• Cellular dynamics may encode temporal and spatial information, offering insights into network-centric views of cell function.
