Overview Endothelium Targeting Solution Targeting Module What We Can Offer? Workflow Our Advantages Published Data FAQs
Are you currently facing challenges with systemic toxicity or inefficient delivery of therapeutic agents to specific disease sites? Our Endothelium Targeting Module Development service at Creative Biolabs helps you overcome these hurdles by providing innovative solutions for precision drug delivery. Leveraging our expertise in advanced protein engineering and nanocarrier technology, we enable therapeutic agents to precisely and efficiently reach the vascular endothelium, unlocking new possibilities for treating a wide range of diseases, from inflammation to cancer.
Overview
The vascular endothelium, a single layer of cells lining the circulatory system, acts as a critical interface between the bloodstream and tissues, functioning as a dynamic and selective semi-permeable barrier. This dynamic layer is active in controlling vascular tone, regulating hemostasis, and modulating immune responses. However, in various pathologies like chronic inflammation, autoimmune disorders, and cancer, the endothelium undergoes a phenotypic shift, becoming "activated." This activation process is characterized by the expression of unique surface markers, such as adhesion molecules (e.g., ICAM-1, VCAM-1) and specific receptors, which are either absent or present at very low levels on the healthy endothelium. These changes make the pathological endothelium an exceptionally accessible and valuable target for selective drug delivery.
Endothelium targeting module development involves creating specific ligands—including peptides, antibodies, and aptamers—that are conjugated to therapeutic payloads. This strategy ensures precise delivery to disease-associated endothelial cells, which serves to enhance efficacy by concentrating the drug at the site of action while dramatically reducing systemic exposure and off-target side effects. This innovative approach provides a significant advantage over traditional systemic therapies, offering a safer and more effective treatment profile.

Creative Biolabs' Endothelium Targeting Solution
Our endothelium targeting strategy guides therapeutic agents to their destination with minimal off-target effects, using two main approaches: passive and active targeting.
Passive Targeting
Nanoparticles (100-200 nm) passively accumulate in leaky vasculature of tumors and inflamed tissues via the Enhanced Permeability and Retention (EPR) effect. While this increases local drug concentration, it is often non-specific and can lead to off-target accumulation.
Active Targeting
The cornerstone of our platform is active targeting, functionalizing delivery systems with specific ligands that bind to receptors overexpressed on pathological endothelial cells. This ensures precise cellular recognition and uptake, allowing for customized modules for diverse therapeutic goals.

Endothelium Targeting Module
The cornerstone of Creative Biolabs' precision drug delivery lies in our advanced targeting modules. These modules are designed to steer our delivery systems straight to particular types of endothelial cells, sometimes even specific subsets. This selective recognition is achieved through high-affinity binding to unique surface markers expressed on the target cells, ensuring that therapeutic payloads accumulate precisely where they are needed, minimizing off-target effects and maximizing therapeutic efficacy. Our diverse library of targeted modules provides unparalleled flexibility in achieving precise endothelium delivery.

Published Data
Fig.3 Anti-PDCE2 antibodies bind to the surface of irradiated endothelial cells under optimized shear flow in a parallel-plate flow system.3,4
In the experiment, the researchers developed an innovative antibody-thrombin conjugate designed to specifically target mitochondrial PDCE2, a protein that becomes ectopically expressed on the surface of endothelial cells following radiation exposure. Utilizing a sophisticated parallel-plate flow system to precisely simulate the dynamic conditions of blood flow within a vascular network, the study demonstrated that this conjugate effectively and precisely induced thrombosis on the irradiated endothelial cells. The experiment successfully confirmed the viability of using these unique, radiation-induced surface changes as a highly specific targeting mechanism. This innovative strategy allows for a novel form of radiation-guided drug delivery, offering a method to induce precision thrombosis in pathological vasculature, such as the neovascularization often found in tumors. This approach has the potential to localize therapeutic effects and minimize systemic harm to healthy tissues, presenting a promising new direction in cancer treatment.
FAQs
Q: Why is targeting the endothelium a valuable strategy for drug development?
A: The endothelium is an accessible, disease-relevant target. Precision drug delivery to these cells achieves high local concentrations, minimizes healthy tissue exposure, and reduces systemic side effects.
Q: Can your targeting modules distinguish between healthy and diseased endothelium?
A: Yes, our modules exploit differences in surface markers between healthy and pathological endothelial cells. By targeting markers overexpressed in diseased states (e.g., tumors), we achieve highly selective delivery.
Q: How does this approach compare to traditional systemic drug delivery?
A: Unlike traditional systemic delivery, which requires high doses and risks off-target toxicity, our targeted approach concentrates the drug where it's needed, allowing for lower doses and a more favorable safety profile.
Q: What kind of payloads can your modules deliver?
A: Our versatile modules integrate with various payloads, including small-molecule drugs, proteins, nucleic acids (siRNA, mRNA), gene editing tools, and diagnostic agents.
Q: What is the typical timeline for developing a custom targeting module?
