The role of microglia and astrocytes in Alzheimer's disease
Pospíšilová, Eva ; Telenský, Petr (advisor) ; Svoboda, Jan (referee)
Alzheimer's disease is a neurodegenerative disease that affects the central nervous system and is characterized mainly by problems with memory abilities. With the more aging population, the number of patients with this disease is gradually increasing, so Alzheimer's disease research is becoming one of the main priorities of today's health care. Although the research has been going on for more than a century, the exact causes of the Alzheimer's disease are still unclear. For a long time, the main role was attributed to the pathology of amyloid β and tau protein, the basic pathophysiological features of this disease, but in recent years, it has become clear that microglia and astrocytes also play an important role. These glial cells affect the amount of amyloid β and the hyperphosphorylated tau protein, but they are also crucial for maintaining homeostasis of the central nervous system. Activation of microglia and astrocytes in Alzheimer's disease can lead to disruption of the physiological functions of these neuroglia, and thus to problems with the removal of amyloid and tau protein, but also to the induction of chronic neuroinflammation. This work aims to summarize and organize the basic knowledge about the role of microglia and astrocytes in Alzheimer's disease, while focusing mainly on their role...
