Abstract:
Reversible pegylated drugs are provided by derivatization of free functional groups of the drug selected from amino, hydroxyl, mercapto, phosphate and/or carboxyl with groups sensitive to mild basic conditions such as 9-fluorenylmethoxycarbonyl (Fmoc) or 2-sulfo-9-fluorenylmethoxycarbonyl (FMS), to which group a PEG moiety is attached. In these pegylated drugs, the PEG moiety and the drug residue are not linked directly to each other, but rather both residues are linked to different positions of the scaffold Fmoc or FMS structure that is highly sensitive to bases and is removable under physiological conditions. The drugs are preferably drugs containing an amino group, most preferably peptides and proteins of low or medium molecular weight. Similar molecules are provided wherein a protein carrier or another polymer carrier replaces the PEG moiety.
Abstract:
A method for treating a disease, disorder, condition or injury of the Central Nervous System (CNS) in a subject in need thereof, comprising administering to said subject a therapeutically effective amount of an active ingredient, such as a non-encephalitogenic or weakly encephalitogenic combination of a Th1 adjuvant and a CNS-specific antigen, causing activation of the choroid plexus of said subject and maintaining said activation by reducing immunosuppression and establishing Th1-type immune response at the choroid plexus thus allowing either anti-inflammatory immune cells or immune cells which acquire a healing phenotype at the cerebrospinal fluid to pass through the choroid plexus, and accumulate at a site of damage in the CNS caused by said disease, disorder, condition or injury is provided.
Abstract:
An autonomous synthetic programmable device adapted to determine a cell state according to one or more different predefined markers, comprising a transcription machinery and a regulatory element for regulating said transcription machinery, said regulatory element comprising at least three different binding regions, each binding region binding a different transcription factor and each binding region corresponding to a different predefined marker, wherein the regulatory element permits said transcription machinery to provide a transcription output if and only if all three different transcription factors are absent and wherein each transcription factor is capable of blocking transcription by said transcription machinery and hence blocking said transcription output.
Abstract:
A method of treating a renal, hepatic or enzyme-deficiency disorder in a subject in need thereof is disclosed. The method is effected by transplanting into the subject tissue derived from a human or porcine, kidney or liver, the kidney or liver being at a selected gestational stage.
Abstract:
Methods of isolating distinct specific cell types within mixed populations of cells. Methods of isolating specific cell types among pancreatic cells, particularly from human islets of Langerhans. Markers and combinations thereof for use in methods of isolating insulin producing islet beta cells for treatment of diabetes.
Abstract:
A method of treating an inflammatory disease is disclosed. The method comprises administering to the subject a therapeutically effective amount of a polypeptide comprising a pro-domain of TNF-alpha converting enzyme (TACE), said polypeptide being devoid of a catalytic domain of said TACE, said polypeptide comprising a modification at a site selected from the group consisting of R58, R56 and K57 which renders said polypeptide resistant to furin degradation said polypeptide being capable of downregulating an activity of TACE, thereby treating the inflammatory disease.
Abstract:
Polynucleotides and polypeptides which participate in influenza virus infection of cells and nucleic acid molecules, which include a polynucleotide sequence capable of specifically binding the polypeptides of the present invention. Also provided are methods of using such nucleic acid molecules, polynucleotides and antibodies directed thereagainst for diagnosing, treating and preventing influenza virus infection.
Abstract:
Isolated polynucleotides and polypeptides encoded therefrom are provided. These include mutated PON enzymes with increased, modified or substantially the same substrate specificity as compared to respective wild-type PON. Also provided are kits and methods using these enzymes.
Abstract:
The present invention provides a method of treating a disease in a subject in need thereof via non-syngeneic graft administration without or with reduced concomitant graft rejection. The method comprises administering to the subject a therapeutically effective graft being non-syngeneic with the subject, and a dose of tolerogenic cells being non-syngeneic with both the subject and the graft for preventing or reducing graft rejection in the subject, thereby treating the disease in the subject
