    摘要: Recombinant adenoviruses comprising a heterologous DNA sequence coding for glial-derived neurotrophic growth factor (GDNF) are provided. The recombinant adenoviruses are useful in a method of expressing GDNF in a cell, wherein the cell is present in a mammal suffering from Parkinson's disease, comprising infecting said cell with a replication-defective recombinant adenovirus comprising a DNA sequence encoding GDNF operably linked to a promoter by administering the adenovirus into cells of the central nervous system. The recombinant adenoviruses of the invention are also useful in a method of treating Parkinson's disease comprising administering into cells of the central nervous system of a mammal suffering therefrom a replication defective recombinant adenovirus comprising ITRs, an encapsidation sequence and a DNA sequence encoding GDNF operably linked to a promoter, wherein the adenovirus E1 gene is non-functional and GDNF is expressed at a level that provides a therapeutic effect.

    摘要: The present invention relates to a method for the separation of biological objects in a solution which have different viscoelastic properties, wherein said method comprises a filtration step allowing the higher viscoelastic biological objects to pass through the membrane while retaining the lower viscoelastic biological objects above the membrane, and a recovery step wherein the separated lower viscoelastic biological objects are recovered above or onto the membrane and/or the separated higher viscoelastic biological objects are recovered in the filtrate. Advantageously, the biological objects are cells. More advantageously, the recovered cells are viable cells. In one preferred embodiment, the cells are tumor cells. In another preferred embodiment, the cells are fetal cells and the method finds an application in prenatal diagnosis.
