The Stimulation Of Dendritic Cells By Cationic Lipids, John Peyton Bush
Theses and Dissertations--Medical Sciences
The discovery that cationic lipids can independently stimulate the immune system has generated interest in their potential as vaccine adjuvants. Here, we show that the cationic lipid R-DOTAP can independently stimulate type 1 interferon production in dendritic cells in both primary culture and immortalized cell culture. Levels of type 1 interferon production are cell line-dependent and limited in vitro by lipid-induced cell death. We show that cationic lipids can independently activate TLR-7 and TLR-9, suggesting a mechanism for type 1 interferon induction. This TLR-stimulatory activity is not restricted to R-DOTAP and can be extended to other similar cationic lipids in …
