This chapter explores the intricate interactions between neurons and astrocytes within the nervous system with a particular emphasis on studies conducted in human tissue or with human cells. We specifically explore how neuron-astrocyte interactions relate to processes of cellular development, morphology, migration, synapse formation, and metabolism. These findings enrich our understanding of basic neurobiology and how disruptions in these processes are relevant to human diseases.The study of human neuron-astrocyte interactions is made possible because of transformative in vitro advancements that have facilitated the generation and sustained culture of human neural cells. In addition, the rise of techniques like sequencing at single-cell resolution has enabled the exploration of numerous human cell atlases and their comparisons to other animal model systems. Thus, the innovations outlined in this chapter illuminate the convergence and divergence of neuron-astrocyte interactions across species. As technologies progress, continually more sophisticated in vitro systems will increasingly reflect in vivo environments and deepen our command of neuron-glial interactions in human biology.

While significant progress has been made in understanding the heterogeneity in the NSCs, our understanding of similar heterogeneity among the more abundant transit amplifying progenitors is lagging. Our work on the NPs of the neonatal subventricular zone (SVZ) began over a decade ago, when we used antibodies to the 4 antigens, Lex CD133,LeX,CD140a and NG2 and FACs to classify subsets of the neontal SVZ as either multi-potential (MP1, MP2, MP3, MP4 and PFMPs), glial-restricted (GRP1, GRP2, and GRP3), or neuron-astrocyte restricted (BNAP). Using RNAseq we have characterized the distinctive molecular fingerprint of 4 SVZ neural progenitors and compared their gene expression profiles to those of the NSCs.

During epileptic seizures, brain activity and connectivity undergo dramatic changes. Brain networks transition from a balanced resting state to a hyperactive and hypersynchronous state. However, the mechanisms driving these state transitions remain unclear.

Alcohol use disorders (AUDs) affect substantial populations worldwide and increase the risk of developing cognitive impairments and alcohol-associated dementia. While chronic inflammatory signaling likely plays an important role in alcohol-associated neurological sequalae, the precise mechanisms underlying alcohol-associated neuropathology remain enigmatic. We hypothesize that alcohol leads to neuroimmune dysregulation among neurons, astrocytes, and microglia; and is perpetuated by innate immune signaling pathways involving cell-cell signaling.

A sustained imbalance between excitatory and inhibitory mechanisms within the glutamatergic and GABAergic systems of the cerebral cortex, induced by noxious stimuli, is a fundamental characteristic in the development and maintenance of chronic pain. This review provides a comprehensive summary of the roles and interaction of glutamatergic and GABAergic systems in the processing of chronic pain signals. Specifically, we present a systematic summary of the processing patterns of the cerebral cortex in the cross-modular integration and output of chronic pain information, according to four aspects, molecular, cellular, neural network and behavioral cognition.

As a gatekeeper of antioxidant and anti-inflammatory cell protection, the transcription factor Nrf2 is a promising therapeutic target for several neurodegenerative diseases, leading to the development of Nrf2 activators targeting Keap1-dependent and independent regulatory mechanisms. Astrocytes play a crucial role in regulating neuronal physiology in health and disease, including Nrf2 neuroprotective responses. As neurons require specific conditions for their differentiation and maintenance, most 2D and 3D co-culture systems use medias that are compatible with neuronal differentiation and function, but also ensure astrocyte survival.
