HDL, HDL-Associated Enzyme, rHDL, sHDL |
Human Study/Animal Model | Effect on Dendritic Cells | References |
---|---|---|---|
Human studies | |||
HDL | Human dendritic cells | Impaired ability to activate T cells, decreased IFN-γ, IL-12 and TNF-α secretion | [270] |
Animal studies | |||
HDL, HDL-PAF-AH | ApoE/LDL-deficiency mouse model | Increased migration, restored immunologic priming | [266] |
rHDL-containing apoA-I and PC | Mouse BMDCs | Decreased MHC class II, CD40, CD80 and CD86 expression and IL-6, IL-8, IL-12, IL-23, TNF-α and IL-10 secretion; decreased Myd88 mRNA levels | [269] |
sHDL | BMDCs from a hepatocellular carcinoma mouse model | Decreased tumor burden triggered immunogenic cell death and induced maturation of dendritic cells | [271] |
A summary of the effects of HDL, reconstituted and synthetic HDL, as well as HDL-associated enzymes on dendritic cell activation and functional properties is given, as described from human studies utilizing monocyte-derived dendritic cells or studies utilizing animal models. Abbreviations: apoA-I—apolipoprotein A-I; apoE—apolipoprotein E; BMDCs—bone marrow-derived dendritic cells; CD—cluster of differentiation; HDL—high-density lipoprotein; IFN-γ—interferon γ; IL—interleukin; LDL—low-density lipoprotein; MHC—major histocompatibility complex; PAF-AH—platelet-activating factor acetylhydrolase; PC—phosphatidylcholine; rHDL—reconstituted high-density lipoprotein; sHDL—synthetic high-density lipoprotein; TNF-α—tumor necrosis factor α.
