Stimulating the regenerative capacity of the human retina with proneural transcription factors in 3D cultures.

Retinal diseases often lead to degeneration of specific retinal cell types with currently limited therapeutic options to replace the lost neurons. Previous studies have reported that overexpression of or combinations of proneural factors in Müller glia (MG) induce regeneration of functional neurons in the adult mouse retina. Recently, we applied the same strategy in dissociated cultures of fetal human MG and although we stimulated neurogenesis from MG, our effect in 2D cultures was modest and our analysis of newborn neurons was limited.

Adult hippocampal neurogenesis is linked to memory formation In the adult brain, with new neurons in the hippocampus exhibiting greater plasticity during their immature stages compared to mature neurons. Abnormal adult hippocampal neurogenesis is closely associated with cognitive impairment in central nervous system diseases. Targeting and regulating adult hippocampal neurogenesis have been shown to improve cognitive deficits.

Ischemic stroke is a significant global health crisis, frequently resulting in disability or death, with limited therapeutic interventions available. Although various intrinsic reparative processes are initiated within the ischemic brain, these mechanisms are often insufficient to restore neuronal functionality. This has led to intensive investigation into the use of exogenous stem cells as a potential therapeutic option.

The large majority of Alzheimer's disease (AD) cases are sporadic with unknown genetic causes. In contrast, only a small percentage of AD cases are familial, with known genetic causes. Paradoxically, there are only few validated mouse models of sporadic AD but many of familial AD.

Amnesia is a memory disorder marked by the inability to recall or acquire information. Hence, drugs that also target the neurogenesis process constitute a hope to discover a cure against memory disorders. This study is aimed at evaluating the antiamnesic and neurotrophic effects of the aqueous extract of () on in vivo and in vitro models of excitotoxicity.
