    摘要: The present invention relates to liposomes for drug delivery, wherein a liposome includes molecules of at least one desired drug distributed within an aqueous phase in the interior of the liposome and wherein the liposome further includes molecules of the same or of another drug attached to either or both sides of the liposomal membrane. More specifically, the invention relates to liposomes, wherein at least a part of the molecules of a desired drug bear a functional group that is reactive with a functional group present in at least one lipid fraction, and wherein the drug is covalently linked to the membrane lipids by chemical bonding, e.g. by ester bonding of a hydroxyl group of a lipid molecule and an acidic residue of the drug. In a preferred embodiment, the desired drug is a glycoprotein such as erythropoietin. The invention further relates to a method of manufacture of said liposomes and to pharmaceutical compositions containing them.

    摘要: The present invention relates to neutralizing anti-HIV-1 antibodies, particularly to mAb 4E10-IgG1, which has an HIV-1 neutralizing potency comparable to the one of mAb 2F5 and 2G12. 4E10-IgG1 binds to a novel conserved epitope (NWFDIT) C-terminal of the ELDKWA epitope recognized by 2F5.1 appears that both epitopes are cryptic epitopes within a region that may be accessible in a virus-cell fusion intermediate state only. 4E10-IgG1 potently neutralizes tissue culture adapted strains but also primary isolates of different clades, including A, B, C, D, and E, inclusing viruses that were found to be resistant to 2F5. None of the tested isolates was resistant to both anti-gp41-antibodies. The invention therefore also relates to peptides containing the 4E10 epitope and to compositions made thereof, as well as to anti-idiotypic antibodies that are reactive with the paratope of 4E10-IgG1, to compositions containing an antiidiotypic antibody optionally in combination with a peptide containing the 4E10 epitope, and to anti-HIV-1 compositions comprising 4E10-IgG1, optionally in combination with another neutralizing antibody such as 2F5 and/or 2G12.
