Calcifying nanoparticles (CNP) in human blood are crucial for pathologic calcification. These particles act as nuclei, initiating crystal formation in various diseases, and their role is increasingly recognized.

Area of Science:

  • Biochemistry
  • Pathology
  • Nanomedicine

Background:

  • Calcification, traditionally viewed as a marker of cell death, is now understood as a key process in numerous diseases.
  • Crystal formation in calcification requires nucleation sites (nidi) and supersaturated conditions, with absent inhibitors.
  • Calcifying nanoparticles (CNP) are calcium phosphate mineral particles found in human blood.

Purpose of the Study:

  • To discuss the critical role of calcifying nanoparticles (CNP) in human pathologic calcification.
  • To explore the controversy surrounding CNP as nidi and triggers for calcification.

Main Methods:

  • Isolation and detection of calcifying nanoparticles (CNP) from human blood.
  • Analysis of CNP presence in various pathologic calcification-related diseases.

Main Results:

  • Calcifying nanoparticles (CNP) were identified as the first calcium phosphate mineral-containing particles isolated from human blood.
  • CNP were detected in numerous diseases associated with pathologic calcification.

Conclusions:

  • Calcifying nanoparticles (CNP) play a critical role in initiating and driving human pathologic calcification.
  • Further research is needed to resolve the controversy regarding the exact function of CNP in disease pathogenesis.
