Cell Type

Function and Description

  • Forms the lining of blood vessels

  • Upon injury, up-regulates cell adhesion molecules on the endothelial cell membrane, which helps to recruit inflammatory cells to the site

  • When injured, releases cytokines and chemokines, which contribute to inflammation

  • Removes microbial intruders and tissue debris

  • Emits substances that activate other inflammatory cells and glial cells and that injure neurons

  • Migrates to area of injury and differentiates into macrophages

  • Releases inflammatory cytokines and free radicals

  • Emits growth factors

  • Removes tissue debris

  • Found in the CNS

  • Has actions similar to those of macrophages

  • Emits inflammatory cytokines

  • Kills cells (cytotoxic killing)

  • Neuroprotection in part by possible secretion of growth factors
