    摘要: The present invention provides for liposomal vectors which inhibit inflammation and/or enhance expression of transferred genes. It is based, at least in part, of the discovery that vectors comprising a nucleic acid carrying a gene of interest and a cationic liposome containing an immunosuppressive agent induce lower levels of inflammatory cytokine relative to conventional lipolex vectors, as well as on the discovery that a component may be incorporated into the liposome which enhances expression of the gene of interest.

    摘要: The present invention provides pharmaceutical compositions and methods for the instillation of lipid vehicles comprised of liposomes containing sphingomyelin or sphingomyelin metabolites to prevent, manage, ameliorate and/or treat disorders involving neuropathic pain and aberrant muscle contractions, such as what occurs in bladder hyperactivity disorders such as interstitial cystitis (IC) in animals or humans in need thereof. Also provided is a liposome-based delivery of drugs, e.g., antibiotics, pain treatments and anticancer agents, to the bladder, genitourinary tract, gastrointestinal system, pulmonary system and other organs or body systems. In particular, liposome-based delivery of vanilloid compounds, such as resiniferatoxin, capsaicin, or tinyatoxin and toxins, such as botulinum toxin is provided for the treatment of bladder conditions, including pain, inflammation, incontinence and voiding dysfunction.

    摘要: Liposomes containing phosphatidylethanolamine, palmitoyl homocysteine or oleic acid or palmitic acid, fuse rapidly when the pH of the medium is reduced below 7. Liposome fusion was measured by (a) mixing of the liposomal lipids as shown by resonance energy transfer, (b) gel filtration and (c) electron microscopy. The presence of phosphatidylethanolamine or acid addition esters thereof in the liposomes greatly enhances fusion; whereas the presence of phosphatidylcholine inhibits fusion. During fusion of liposomes containing phosphatidylethanolamine:palmitoyl homocysteine (8:2), almost all of the encapsulated calcein is released. Inclusion of cholesterol (40%) in the liposomes substantially decreases leakage without impairing fusion. Those pH sensitive liposomes are fused to deliver biologically active molecules such as DNA, into living cells.
