Assembly and function of the natural killer cell immune synapse

Area of Science:

• Immunology
• Cell Biology

Background:

• The natural killer (NK) cell immune response relies on the formation of the natural killer cell immune synapse (NK-IS).
• NK-IS is a supramolecular structure at the cell interface, crucial for regulating NK cell activation and target cell fate.
• Key components include cytoskeletal elements, adhesion and signaling molecules, and receptors.

Purpose of the Study:

• To review the current knowledge on the organization and physio-pathological function of inhibitory, cytotoxic, and activating NK-IS.
• To summarize microspectroscopy techniques for live cell imaging of dynamic biochemical processes in NK cell immune responses.

Main Methods:

• Literature review of NK-IS organization and function.
• Summary of microspectroscopy techniques for live cell imaging.

Main Results:

• Detailed presentation of the organization and physio-pathological roles of different NK-IS types (inhibitory, cytotoxic, activating).
• Overview of advanced imaging techniques enabling visualization of dynamic cellular processes.

Conclusions:

• The NK-IS is a complex, dynamic structure essential for effective NK cell-mediated immunity.
• Microspectroscopy offers powerful tools for understanding the biochemical dynamics underlying NK cell immune responses.
