Lithium treatment and human hippocampal neurogenesis

Project description:Lithium is a first-line treatment for bipolar disorder, where it acts as a mood-stabilizing agent. Although its precise mechanism remains unclear, neuroimaging studies have shown that lithium accumulates in the hippocampus and that chronic use amongst bipolar disorder patients is associated with larger hippocampal volumes. Here, we tested the chronic effects of low (0.75 mM) and high (2.25 mM) doses of lithium on human hippocampal progenitor cells and used immunocytochemistry to investigate the effects of lithium on cell parameters implicated in neurogenesis. Corresponding RNA-sequencing and gene-set enrichment analyses were used to evaluate whether genes affected by lithium in our model overlap with those regulating the volume of specific layers of the dentate gyrus. We observed that high-dose lithium treatment in human hippocampal progenitors increased the generation of neuroblasts (P ≤ 0.01), neurons (P ≤ 0.01), and glia (P ≤ 0.001), alongside the expression of genes which regulate the volume of the molecular layer of the dentate gyrus. This study provides empirical support that adult hippocampal neurogenesis and gliogenesis are mechanisms that could contribute to the effects of lithium on human hippocampal volume.

Spatial transcriptomics analysis of adult hippocampal neurogenesis in the human brain

Project description:Adult hippocampal neurogenesis (AHN) has been extensively characterized in rodent models, but its existence in humans remains controversial. We sought to assess the phenomenon in post-mortem human hippocampal samples by combining spatial transcriptomics and fluorescent in situ hybridization. We detected very few cells expressing neural stem cell- and proliferation-specific genes in the human dentate gyrus (DG) from childhood to middle age, suggesting very low levels of hippocampal neurogenesis throughout life. However, we observed at all ages a significant number of DG cells expressing the immature neuronal marker DCX. The majority of DCX+ cells displayed an inhibitory phenotype, while the remainder were non-committed or excitatory in nature. Overall, our study investigates for the first time the extent of AHN in the human brain with spatial transcriptomic tools and reveals important insight into the distribution and phenotype of cells expressing neurogenesis markers in the adult human hippocampus.

Microglia actively remodels adult hippocampal neurogenesis through the phagocytosis secretome

Project description:During adult hippocampal neurogenesis, the majority of newborn cells undergo apoptosis and are rapidly phagocytosed by resident microglia in order to avoid disturbing the surrounding neurons. Here, we propose that phagocytosis is not merely a passive process of corpse removal but has an active role in maintaining adult hippocampal neurogenesis. First, we found that neurogenesis was disrupted in three defective microglial phagocytosis KO models in vivo (P2Y12, MerTK/Axl , GPR34). We then followed an in vitro approach to perform a transcriptomic analysis of microglial phagocytosis and identified genes involved in metabolism, chromatin remodeling, and neurogenesis-related functions. Finally, we determined that the phagocytic microglia secretome limits the production of new neurons both in vivo and in vitro. Our data suggest that reprogrammed phagocytic microglia acts as a sensor of local cell death, modulating the balance between cell proliferation and cell survival in the neurogenic niche, supporting the long-term maintenance of adult hippocampal neurogenesis.

Microarray analysis of the leukocyte global gene expression profile following lithium treatment

Project description:To further development of our gene expression approach to lithium pharmacodynamics, we have employed whole genome microarray expression profiling as a discovery platform to identify genes with the potential to distinguish lithium pharmacodynamics across an exposure range relevant for medical decision-making in lithium therapy. 8 healthy male subjects participated in this study. Lithium was prescribed for 2 weeks, enough to reach a therapeutic serum concentration (0.6-1.0mM). Leukocyte counts and serum lithium concentrations were determined at baseline (before medication), after 1 week and 2 weeks medication and post-2-weeks (2 weeks after stopping medication). Gene expression profiling was performed at each time point using Agilent G4112F Whole Human Genome arrays containing approximately 44,000 probe sets. Some of the candidate gene expressions were also determined by real-time PCR. Lithium-induced gene expression in human blood was measured at baseline, after 1 week and 2 weeks of treatment, and after 2 weeks after stopping medication. 4 independent experiments were performed (baseline, 1wk, 2wk, after 2wk) using mixed samples from each donor.

Mediator Med23 regulates adult hippocampal neurogenesis

Project description:we provide evidence that Med23 is involved in the regulation of adult hippocampal neurogenesis in mouse. Med23-deficient NSCs in the SGZ display faster self-renewal activity possibly by reducing cell cycle length, but neuroblasts, immature and mature new-born neurons are reduced.
