Clodrosome macrophage scavenger clodronate liposomesProduct Overview

Macrophages are an important component of the immune system, responsible for recognizing, engulfing, and clearing foreign pathogens and cellular debris. They play a crucial role in regulating immune responses, tissue repair, and maintaining homeostasis. Studying the function of macrophages is of great significance for understanding the pathogenesis of various diseases, developing new treatment strategies, and improving clinical efficacy. Macrophages not only participate in the defense against infection, but also play complex and diverse roles in pathological processes such as autoimmunity, tumorigenesis, and cardiovascular disease. By revealing the functional changes of macrophages in different physiological and pathological states, research can provide a basis for the design of new immunotherapy and promote the development of personalized medicine. Therefore, promoting research on macrophage function is an important task in modern medical research and has broad application prospects.

The clearance of macrophages is a powerful research method for comprehensively understanding the function of macrophages under pathological conditions. Clodronate Liposomes are currently a mature, convenient, and economical tool for macrophage clearance, which can effectively remove macrophages from different parts of the body and blood.

Chlorophosphonate salt（Clodronate is a bisphosphonate drug mainly used clinically for cancer induced osteolytic bone metastasis, osteoporosis, and hypercalcemia. Its mechanism of action is that chlorophosphonate is metabolized into non hydrolyzable ATP analogs in cells, inhibiting the ADP/ATP transport mechanism in mitochondria, thereby blocking the mitochondrial respiratory chain and inducing cell apoptosis. However, the drug has low lipophilicity and cannot be transported across cells. After oral or intravenous administration of the free drug, its half-life can be reached within 2 hours, and 80% of the drug is excreted in urine within 48 hours.

Liposomes are spherical vesicles with single or multiple lipid bilayers, mainly composed of phospholipids and sterols. Liposomes themselves have a bilayer structure and are composed of non-toxic components, making them a carrier for transporting molecular substances. They transport molecular substances into cells by binding to the cell membrane.

Chlorophosphonate is encapsulated in the aqueous phase of phospholipids to form chlorophosphonate liposomes, which cannot freely pass through the phospholipid bilayer of liposomes. After injection into the body, chlorophosphate liposomes are engulfed by macrophages. Under the action of lysosomal phosphatase in macrophages, chlorophosphates dissolved in liposomes are gradually released and accumulated in cells. When a certain concentration is reached, macrophages will suffer irreversible damage and induce cell apoptosis. Chlorophosphonates in dead cells are released into the extracellular space and excreted with urine.
