In recent years, the important role of microglia in synapse formation, elimination, and plasticity is gradually being recognized. Synapses are the main communication mode between neurons. They undergo constant changes in quantity and plasticity throughout the life cycle, which is the basis of learning and memory. Microglia are highly motile, branched forms that monitor the microenvironment of the central nervous system (CNS) and promote synapse formation and maturation. They recognize and phagocytose redundant synapses through specific phagocytosis receptors. Furthermore, microglia regulate synaptic plasticity by releasing various effectors. The roles of microglia on synapses ensure the proper function of neural networks. Synaptic dysfunction and microglia activation are common features in CNS disorders, such as Alzheimer's disease, Parkinson's disease, ischemic stroke, cerebral hemorrhage, traumatic brain injury, multiple sclerosis, and epilepsy. Highly heterogeneous microglia exhibit diverse functions in these diseases and participate in disease progression by exacerbating or inhibiting synaptic dysfunction, in addition to neuroimmune and inflammation. In this article, we summarize the role of microglia on synapses under physiological conditions and in CNS disorders. We highlight the possible mechanisms by which microglia regulate synapse function in CNS disorders and how this affects the progression of the diseases.

Various stressors trigger the integrated stress response (ISR) signaling, whose highly conserved mechanism is primarily aimed at protecting a stress-exposed cell to cope as safely as possible with such stressful conditions. On the contrary, if a cell is unable to cope with excessive stress, the ISR can induce apoptosis. The ISR mechanism, whose main stage is the inhibition of translation machinery in favor of the synthesis of specific proteins, including the transcription factors ATF3, ATF4, CEBPA, and CEBPB, which function only as dimers and determine the uniqueness of the ISR response in each individual case, thus ensures different outcomes of the ISR. Inhibition of global protein synthesis is achieved through phosphorylation of eIF2α by PERK, HRI, PKR, or GCN2. To date, a number of compounds have been developed that modulate the ISR, including activators and inhibitors of the abovementioned ISR kinases as well as modulators of p-eIF2α dephosphorylation. They target different ISR stages, allowing a broad ISR modulation strategy. At the same time, there are no drugs that are both exceptionally safe and effective for the treatment of several neurological diseases, so there is an urgent need for new approaches to the treatment of these disorders.

Several studies have demonstrated that epigenetic mechanism play a pivotal role in the development and progression of epilepsy. This review provides a comprehensive overview of epigenetic regulation and its role in epilepsy. We emphasize the specific role of epigenetic regulation, including DNA methylation, non-coding RNA, and histone modification in the epilepsy. Finally, we discuss the potential applications of epigenetic regulation in the etiology research, drug development, and personalized therapy of epilepsy, along with the technical and theoretical challenges that need to be addressed in epigenetic research. Epigenetic mechanisms have emerged as a promising avenue for understanding the pathogenesis and treatment of epilepsy. However, to thoroughly grasp its potential implications for the clinical management of this disease, a deeper understanding of the role of epigenetics in TLE is essential.
