ApoB-Depleted Serum, HDL, HDL-Associated Protein/Lipid, Mimetic Peptide | Human Study/Animal Model | Effect on Eosinophils | References |
---|---|---|---|
Human studies | |||
apoB-depleted serum, HDL | Allergic rhinitis patients, human eosinophils | Inhibited shape change and chemotaxis | [28] |
HDL | Atopic dermatitis patients, human eosinophils | Decreased ability to inhibit shape change and chemotaxis | [34] |
HDL, apoA-I, apoA-IV | Allergic patients, human eosinophils | Decreased chemotaxis, accelerated apoptosis | [29] |
Stable LPC analog Miltefosine | Human eosinophils | Inhibited shape change, CD11b expression, chemotaxis, degranulation, CD63 expression and Ca2+ flux | [253] |
Animal studies | |||
apoA-I, apoA-IV, 5A-peptide | House dust mite-induced asthma mouse model | Decreased bronchoalveolar lavage fluid eosinophils | [29,31,228] |
D-4F | OVA-challenged mouse model | Decreased airway eosinophilia | [255] |
LPC 18:0 | Allergic cell recruitment mouse model | Decreased infiltration into the lungs | [72] |
Stable LPC analog Miltefosine | Allergic cell recruitment; allergic lung inflammation mouse models | Suppressed eosinophil migration into the bronchoalveolar lavage; reduced eosinophil numbers, improved lung resistance | [253] |
A summary of the effects of apoB-depleted serum, HDL, HDL-associated apolipoproteins and lipids, as well as apoA-I mimetic peptides on eosinophil activation and functional properties is given, as described from human studies utilizing primary eosinophils or studies utilizing animal models. Abbreviations: apoA-I—apolipoprotein A-I; apoA-IV—apolipoprotein A-IV; apoB—apolipoprotein B; CD—cluster of differentiation; HDL—high-density lipoprotein; LPC—lysophosphatidylcholine; OVA—ovalbumin.
