Overview Macrophage Targeting Solution Targeting Module What We Can Offer? Workflow Our Advantages Published Data FAQs
Macrophages are adaptable immune cells crucial for both maintaining health and contributing to diseases. Their widespread presence and significant role in various conditions—including inflammation, infections, cancer, and autoimmune diseases—make them very attractive and essential targets for cutting-edge treatments. At Creative Biolabs, we empower researchers and pharmaceutical companies with cutting-edge, macrophage-specific solutions for targeted drug delivery.
Overview
Macrophages are versatile and highly dynamic immune cells crucial for maintaining tissue homeostasis and orchestrating immune responses. Originating from monocytes that circulate in the blood, they migrate into tissues and differentiate into diverse subsets, each with distinct functions. They act as professional phagocytes, engulfing cellular debris, pathogens, and foreign particles. Beyond phagocytosis, macrophages play pivotal roles in antigen presentation, cytokine secretion, and tissue repair. Their remarkable plasticity allows them to adopt either pro-inflammatory (M1) or anti-inflammatory/repair-promoting (M2) phenotypes, depending on the microenvironmental cues. This plasticity is particularly significant in disease contexts. In tumors, tumor-associated macrophages (TAMs) often adopt an M2-like phenotype, supporting tumor growth, angiogenesis, immunosuppression, and metastasis. Conversely, in chronic inflammatory diseases, dysregulated macrophage activity can perpetuate tissue damage. Understanding and manipulating macrophage behavior is therefore a critical goal in immunotherapy and regenerative medicine.

Creative Biolabs' Macrophage Targeting Solution
Creative Biolabs' precision delivery platform centers on our macrophage-homing agents. These engineered units are constructed for incorporation into diverse carriers, including lipid-based nanocarriers (LNPs), liposomal vesicles, or exosomal bodies. Carriers undergo functionalization with targeting agents – specialized ligands identifying macrophage-abundant receptor complexes or membrane signatures. Uptake mechanisms involve initial nanoscale passive homing, succeeded by active receptor-mediated internalization upon agent-marker engagement. This binding instigates macrophage internalization, securing confined payload transport. Our architectural framework enables adaptable customization for varied investigative and therapeutic objectives.
Passive Targeting
Precisely sized nanoparticles (100-200 nm) are capable of passively amassing in areas of compromised vasculature, such as tumors or inflamed tissues, due to the Enhanced Permeability and Retention (EPR) effect. Subsequently, macrophages, being highly phagocytic cells, readily consume these amassed particles.

Active Targeting
Our macrophage-targeting module development is founded on active targeting, a process of modifying delivery systems with particular ligands. These ligands attach to receptors overexpressed on the surface of macrophages or certain macrophage subsets, thereby ensuring accurate cellular recognition and absorption.

Macrophage 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 macrophages, 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.
Creative Biolabs' diverse library of targeted modules provides unparalleled flexibility in achieving precise macrophage delivery. Each module type offers distinct advantages in terms of specificity, stability, and ease of conjugation to our various delivery systems.
Key Macrophage Surface Markers
Macrophage populations are remarkably diverse, exhibiting distinct phenotypes and functions depending on their tissue microenvironment and activation state. By understanding these specific markers, we can design and synthesize targeting modules that bind with unparalleled specificity.

Our macrophage targeting module is a core component of our advanced delivery system, engineered for precise interaction with macrophage surface receptors. It typically consists of a high-affinity ligand (e.g., a peptide, antibody fragment, or carbohydrate) specifically chosen for its binding to a target marker like CD206, SR-A, or CD36, conjugated to a linker that facilitates stable attachment to the delivery vehicle (liposomes, exosomes, micelles, polymer nanoparticles, etc.). This modular approach allows for flexibility and optimization.
