Structure and dynamics of macrophage podosomes

Eur J Cell Biol. 2006 Apr;85(3-4):145-9. doi: 10.1016/j.ejcb.2005.08.006. Epub 2005 Sep 12.


Podosomes are short-lived, dynamic actin-rich adhesions classically formed in macrophages, osteoclasts and Src-transformed fibroblasts. Though related to the more commonly studied focal adhesions, sharing several structural and regulatory proteins, podosomes have distinct functional, structural, and dynamic characteristics. Here, we discuss current understanding of the function of podosomes in disparate cell types and how this relates to their structure and dynamics.
