Glial cell line-derived neurotrophic factor and is the first member of the GDNF family of ligands (GFL) found. Glial cell line-derived neurotrophic factor has been shown to interact with GFRA2 and GDNF family receptor alpha 1. GDNF has regenerative properties for brain cells and showed potential as treatment for Parkinson's disease - monkeys with an induced form of Parkinson's disease showed less trembling when treated with the drug, and neuronal fibres grew in part of the human brain exposed to the drug. However progress to a treatment is hampered by the problem of delivering the drug to brain cells through the blood-brain barrier in human.
Human germline engineering by their pseudonyms, Lulu () and Nana (). Human germline engineering Human germline engineering is the process by which the genome of an individual is edited in such a way that the change is heritable. This is achieved through genetic alterations within the germinal cells, or the reproductive cells, such as the oocyte and spermatogonium. Human germline engineering should not be confused with gene therapy. Gene therapy consists of altering somatic cells, which are all cells in the body that are not involved in reproduction. While gene therapy does change the genome of the targeted cells, these cells are not
