Abstract

Parkinson's disease (PD) is a neurodegenerative disorder with a complex and multifactorial pathogenesis. This chapter delves into the critical role of astrocytes in PD. Once viewed as supporting cells in the central nervous system, astrocytes have emerged as key players in both maintaining neuronal health and contributing to neurodegeneration in PD. Their functions play a dual role in the progression of PD, ranging from protective functions like secretion of neurotrophic factors and clearance of α-synuclein to detrimental functions like promotion of neuroinflammation. This chapter is structured into three primary sections: the morphological and functional organization of astrocytes, astrocytic calcium signaling, and the role of astrocyte heterogeneity in PD. We provide a detailed exploration of astrocytic organelles, bidirectional astrocyte-neuron interactions, and the impact of astrocytic secretions such as antioxidant molecules and neurotrophic factors. Furthermore, we discuss the influence of astrocytes on non-neuronal cells, including interactions with microglia and the blood-brain barrier (BBB). By examining the multifaceted roles of astrocytes, in this chapter, we aim to bridge basic astrocyte biology with the clinical complexities of PD, offering insights into novel therapeutic strategies. The inclusion of astrocyte biology in our broader research approach will aid in the development of more effective treatment strategies for PD.
