Leptin targets spatially diverse neurons

Leptin is a hormone that is secreted by fat and signals the need to stop eating and increase energy expenditure via leptin receptors (LepR). Various hunger and reward centers in the brain contain different LepR expressing neurons. The primary leptin center is the well-studied arcuate nucleus. Other hypothalamic nuclei are …

Characterising social stress responsive ventral tegmental area neurons

In this study published at Frontiers in Behavioral Neuroscience, Ioannis Koutlas and colleagues of the Meye lab, use the expression of immediate-early genes to characterize social-stress activated neuronal subsets in the ventral tegmental area. They show that cells of different molecular identities (dopaminergic, GABAergic, glutamatergic and combinatorial neurons) that are …

Cellular diversity of the developing mouse Habenula

The habenula (Hb) plays a key role in processing reward information and mediating aversive responses to negative stimuli. In the recent issue of Cell Reports, Lieke van de Haar and colleagues have revealed how the cellular diversity of the mouse habenula is formed during development. In the work title “Cellular …

Astrocyte function in early-stage Alzheimer’s disease on GLIA

Astrocytes are literally the star cells of our brains! PhD candidate Christiaan Huffels, from the group of Elly Hol, recently published a study on astrocyte function in early-stage Alzheimer’s disease in the scientific journal GLIA. Alzheimer’s Disease is the main form of dementia in the elderly, characterised by the accumulation …
