Core Tip

Core Tip: Astrocytes are a part of neuroglia with extremely diverse morphology and functions. They participate in numerous physiological processes, such as regulation of axonal growth and support, blood-brain barrier formation, immune responses as well as functioning in higher cognitive functions, including memory. Since modern research has confirmed the morphological diversity of astrocytes both in vitro and in vivo, they remain in the centre of investigation.
