VEGF is a family of secreted polypeptides essential for the development and maintenance of vascular and lymphatic systems. It plays a vital role during embryonic development and in adult physiology, such as wound healing and tissue repair. The VEGF protein acts by binding to specific receptors on cell surfaces, primarily VEGFRs (VEGF Receptors), initiating signaling pathways that lead to endothelial cell proliferation, migration, and survival作者：Y Zhang·2017·被引用次数：58—Thispeptidewas found to dose-dependently inhibit the proliferation of human umbilical vein endothelial cells stimulated byVEGF..
Peptides that interact with VEGF or its receptors are being explored for various purposes. These can include:
* VEGF Alternative Peptides: Some synthetic peptides, like PG-007, are designed to mimic the function of VEGF, acting as agonists for VEGFR2.作者：I Guryanov·2021·被引用次数：24—Vascular endothelial growth factors (VEGFs) are the family of extracellular signaling proteins involved in the processes of angiogenesis. These can promote endothelial cell proliferation and are used in research to study angiogenesis.
* VEGF Receptor Binding Peptides: Other peptides are engineered to specifically bind to VEGF receptors.PG-007VEGF Alternative Peptide (VEGFR2 agonist) These might act as inhibitors or modulators of VEGF signaling, potentially useful in blocking excessive or pathological angiogenesisβ-Hairpin Peptide That Targets Vascular Endothelial ....
* VEGF Mimicking Peptides: Research also focuses on creating peptides that mimic the binding sites of VEGF-A and VEGF-B. These can be used to inhibit VEGFR-1/-2 driven angiogenesis, which is often implicated in tumor growth and metastasis.
* Blocking Antibodies and Peptide Conjugates: Synthetic peptides can also be designed for use in combination with antibodies, for example, to block an antibody from binding to its target protein, as seen with anti-VEGFA antibodies.
The manipulation of VEGF signaling pathways through peptides holds significant therapeutic promise, particularly in oncology and ophthalmology.
* Cancer Therapy: By inhibiting VEGF-driven angiogenesis, which tumors rely on for nutrient supply and growth, peptide-based therapies can potentially slow or halt tumor progression. VEGF/VEGFR2 peptide vaccines, for instance, have been investigated for their ability to induce anti-tumor immune responses.
* Ocular Diseases: Conditions like neovascularization in the eye, which can lead to vision loss, are also targets for anti-VEGF therapies. Nanogel formulations of anti-VEGF peptides are being developed for localized ocular treatment.
* Regenerative Medicine: In contrast to anti-angiogenic applications, peptides that promote VEGF expression, such as TB-500, are explored for their potential in injury repair and regeneration by stimulating growth factors.
Beyond therapeutic potential, vegf peptide and related compounds serve as crucial tools in biological research. They are used to study the intricate mechanisms of angiogenesis, cell signaling, and disease pathology. For example, synthetic peptides are designed to block specific interactions within the VEGF pathway, allowing researchers to dissect its components.作者：D Diana·2011·被引用次数：46—VEGFis a cytokine affecting proliferation, migration, and survival of endothelial cells (ECs) (1), and it is involved in pathological ...
It is important to note that the use of peptides, including those related to VEGF, can extend into areas like athletic performance enhancement. However, substances that mimic or modulate growth factors like VEGF are often prohibited by anti-doping agencies due to concerns about unfair advantage and potential health risks. The World Anti-Doping Agency (WADA) lists peptide hormones, growth factors, and related substances, including VEGF, as prohibited.
The field of vegf peptide research continues to evolve, with ongoing efforts to design more specific, potent, and stable peptide-based agents. Challenges include ensuring targeted delivery, managing potential off-target effects, and optimizing pharmacokinetic properties.作者：D Diana·2011·被引用次数：46—VEGFis a cytokine affecting proliferation, migration, and survival of endothelial cells (ECs) (1), and it is involved in pathological ... Structure-based design is a key strategy for developing peptides that precisely mimic or block critical binding interactions within the VEGF system, paving the way for more effective and safer applications in both research and clinical settings.
