The fibronectin/integrin alpha5 partnership is essential for the proliferation of inflammatory preadipocytes.
Blocking the interaction between fibronectin and integrin alpha5 can stop the proliferation of fat precursor cells in a fibrotic environment.
GoodSupportsHIGH confidence
Anti-alpha5 integrin-neutralizing antibody decreased proliferation of these cells, underlining the importance of the fibronectin/integrin partnership.
Why this rating
Supported by neutralizing antibody and cell culture experiments.

- Macrophage-secreted factors induce a profibrotic phenotype in human preadipocytes, characterized by increased proliferation, migration, and synthesis of extracellular matrix (ECM) proteins like fibronectin and collagen I.Good
- Inhibin A, secreted by macrophages or induced in preadipocytes, is a major profibrotic factor driving the synthesis of fibronectin and collagen I.Good
- NF-kappaB and Cyclin D1 are critical molecular links connecting inflammation, ECM remodeling, and preadipocyte proliferation.Good
