Abstract
Carbon nanotubes (CNTs) are quite attractive as drug delivery vehicles for targeted organ, tissue and systemic therapy. However, how these drug-laden CNTs interact with components of the immune system can have profound effect on the intended outcome of the drug delivery. For instance, the nature of interaction between CNTs and immune cells, such as phagocytes, can lead to rapid elimination of the nanoparticles from the systemic circulation, and thus, interfere with specific delivery. Furthermore, engagement of phagocytic cells with CNTs can activate a string of innate immune pathways, precipitating in an inflammatory response and modulation of adaptive immune system. Therefore, understanding the interactions between nanoparticles and immune system is essential for their strategic and specific use for in vivo delivery. Since innate immune system offers the first line of defense and clearance mechanism against non-self and altered self, we have shown via a string of studies that the complement system sees the molecular pattern on pristine and derivatised CNTs. CNTs that activate the complement are phagocytosed more efficiently and induce an anti-inflammatory response as compared to non-complement activating CNTs. Thus, pattern recognition and complement deposition can determine the fate of CNT-mediated drug delivery. This concept is now being exploited, using recombinant forms of soluble innate immune humoral factors immobilized on various CNTs, to target glioblastoma, graft rejection and allergy.
