VEGFfamiljens

VEGFamiljens is a term used to refer to the Vascular Endothelial Growth Factor family of proteins. These proteins play a crucial role in the formation of new blood vessels, a process known as angiogenesis. Angiogenesis is vital for normal physiological processes such as embryonic development, wound healing, and the female reproductive cycle. However, it is also implicated in pathological conditions, including tumor growth and metastasis, as well as diseases affecting the eye and joints.

The VEGF family comprises several members, with VEGF-A being the most extensively studied and functionally significant. Other members include VEGF-B, VEGF-C, VEGF-D, and Placental Growth Factor (PlGF). Each member has distinct but often overlapping roles in regulating vascular development and function. These proteins exert their effects by binding to specific receptor tyrosine kinases on the surface of endothelial cells, triggering downstream signaling pathways that promote cell proliferation, migration, and survival.

The dysregulation of VEGF signaling is associated with a wide range of diseases. In cancer, tumors often produce high levels of VEGF to stimulate the growth of new blood vessels that supply them with oxygen and nutrients, enabling them to grow and spread. Conversely, inhibiting VEGF signaling has become a major therapeutic strategy in cancer treatment, with several anti-VEGF drugs approved for clinical use. Beyond cancer, aberrant VEGF activity is also implicated in conditions like diabetic retinopathy, age-related macular degeneration, and rheumatoid arthritis, making it a significant target for therapeutic intervention across various medical fields.
