An isolated oxidation-resistant ApoA1 variant dimer includes a first oxidation-resistant ApoA1 variant polypeptide monomer and a second oxidation-resistant ApoA1 variant polypeptide monomer, wherein at least one of the first and the second monomers comprises at least one amino acid substitution of a tryptophan residue for an oxidation resistant amino acid, or a functional fragment or variant thereof. Methods for treating a disease or disorder comprises administering to a subject in need thereof, a therapeutically effective amount of an isolated oxidation-resistant ApoA1 variant dimer, an oxidation-resistant ApoA1 variant monomer, an oxidation-resistant ApoA1 monomer -lipid complex, a lipid complexed oxidation-resistant ApoA1 variant monomer, a lipid complexed oxidation-resistant ApoA1 variant dimer, or combinations thereof to the subject to enhance cholesterol efflux activity in the presence of an oxidant. |
