Eigenschaften
CCL2 wird an Orten einer EntzΓΌndung von Monozyten, T-GedΓ€chtniszellen und dendritische Zellen gebildet, sezerniert, an Proteoglykane von Endothelzellen gebunden, durch die Matrix-Metalloprotease 12 (MMP-12) proteolytisch aktiviert und bindet dann diese Zelltypen dort.cite-ref-pmid8170963-1-0[1]cite-ref-pmid8830793-2-0[2]cite-ref-pmid2465924-3-0[3]cite-ref-pmid2923622-4-0[4] CCL2 wird auch von Neuronen, Astrozyten und Mikroglia gebildet. Die Genexpression des CCL2 ist vornehmlich im Cortex cerebralis, im Globus pallidus, im Hippocampus, in den paraventrikulΓ€ren und supraoptischen hypothalamischen Nuclei, in der Substantia nigra, im Nucleus motorius nervi facialis, in den trigeminalen motorischen und spinalen Nuclei, im gigantozellulΓ€ren retikulΓ€ren Nucleus und in den Purkinje-Zellen des Cerebellums.cite-ref-banisadr-5-0[5]
CCL2 wird von den Rezeptoren CCR2 und CCR4 gebunden.cite-ref-pmid17160712-6-0[6] Nach Stimulation von Zellen mit CCL2 wird die Genexpression von MCPIP1 induziert.
