CCL3 (Macrophage Inflammatory Protein-1α, MIP‑1α)
-CCL3 acts as a chemoattractant for various immune cells including NK cells, dendritic cells, and monocytes.
– Its role in tumors can be dual: promoting anti-tumor responses in some contexts while in others, especially through chronic inflammation, it may participate in tumor progression.
CCL3 - C-C Motif Chemokine Ligand 3
Abbreviation: CCL3, MIP-1α
Type: Chemokine / inflammatory cytokine
Function: CCL3 is a CC-family chemokine that signals primarily through CCR1 and CCR5 and regulates recruitment and activation of monocytes, macrophages, lymphocytes, and other immune cells. It plays important roles in inflammatory responses, immune-cell trafficking, and tumor-microenvironment signaling.
Cancer: ↕ Context-dependent. CCL3 can support antitumor immune-cell recruitment in some settings, but elevated CCL3 frequently promotes a pro-inflammatory tumor microenvironment, recruitment of tumor-supportive myeloid cells, angiogenesis, invasion, metastasis, and treatment resistance.
Alzheimer's Disease: ↑ Increased CCL3 is associated with neuroinflammation and activation or recruitment of microglia and other immune cells in Alzheimer's disease and related neurodegenerative models.
