CCL2MCP1driven

CCL2MCP1driven describes biological processes in which the chemokine CCL2, also known as monocyte chemoattractant protein-1 (MCP-1), and its receptor CCR2 dominate the recruitment of monocytes and other CCR2-expressing cells to sites of inflammation, injury, or remodeling. The term is used to indicate that CCL2/CCR2 signaling is the principal driver of cellular trafficking in a given context, although it often operates within a network of chemokines and cytokines.

Mechanistically, CCL2 is produced by a range of cell types, including endothelial cells, fibroblasts, adipocytes, macrophages, and astrocytes, in response to inflammatory stimuli. It binds to CCR2, a G protein–coupled receptor, triggering chemotaxis and downstream signaling that promotes leukocyte migration, monocyte differentiation into macrophages, and amplification of inflammatory responses. The CCL2–CCR2 axis can act in concert with other chemokines and mediators to shape the composition of tissues during inflammation and repair.

CCL2MCP1driven processes are implicated in diverse conditions. In cardiovascular disease, obesity-related inflammation, and kidney pathology, elevated CCL2/CCR2 activity correlates with monocyte/macrophage infiltration and damage. In the nervous system, CCL2 contributes to microglial recruitment and neuroinflammation. In oncology, CCL2 can recruit tumor-associated macrophages that influence tumor progression and metastasis. The axis is also a target of therapeutic exploration, with approaches aiming to block CCL2 or CCR2 to reduce pathological monocyte recruitment; clinical results have been mixed due to redundancy in chemokine networks and compensatory pathways.

In summary, CCL2MCP1driven denotes inflammation or tissue remodeling where CCL2/CCR2 signaling is a key, though often part of a broader chemokine system.
