Background:

• Synthetic nanoparticles face immune system clearance (phagocytosis) due to insufficient biological functionalization, limiting targeted drug delivery.
• Immunocyte membranes naturally facilitate intercellular interactions and can shield foreign nanomaterials.
• Biomimetic nanotechnology leveraging cell membranes is a rapidly advancing field.

Purpose of the Study:

• To summarize the development of immunocyte membrane-coated nanoparticles for tumor immunotherapy.
• To review existing immunocyte membrane-coated nanocarriers.
• To discuss challenges in large-scale preparation and application of these nanocarriers.

Main Methods:

• Review of scientific literature on immunocyte membrane-coated nanoparticles.
• Analysis of biomimetic nanotechnology strategies for cancer immunotherapy.
• Identification of various immunocyte membrane-derived nanocarriers.

Main Results:

• Immunocyte membrane coating provides a natural barrier, protecting nanoparticles from immune clearance.
• This biomimetic approach enhances the biological significance and therapeutic potential of nanoparticles.
• Several types of immunocyte membrane-coated nanocarriers have been developed for tumor immunotherapy.

Conclusions:

• Immunocyte membrane-coated nanoparticles represent a promising strategy for overcoming the limitations of conventional nanoparticles in drug delivery.
