Glial growth factor (GGF) is a protein that plays a crucial role in the development and maintenance of glial cells within the nervous system. These specialized cells provide support and insulation to neurons, facilitating their proper functioning. Synonyms for GGF include glial cell line-derived neurotrophic factor (GDNF) and astrocyte-derived trophic factor (ADTF). Both terms are used interchangeably with GGF to describe the same protein and its functions. GDNF and ADTF are essential for promoting the survival, growth, and differentiation of glial cells, thereby contributing to the overall well-being and integrity of the nervous system. These synonyms enhance our understanding of the diverse nomenclature used to refer to this vital protein.
