Reuniens Nucleus (Re) Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The nucleus reuniens (Re) is a midline thalamic nucleus that serves as a critical relay between the hippocampus and prefrontal cortex. It plays a essential role in episodic memory, spatial navigation, and hippocampal-prefrontal cortex synchronization during cognitive processing. [1]

The Reuniens nucleus has distinctive features:
The Reuniens is crucial for hippocampal-cortical communication:
Key differentially expressed genes in Re neurons include:
| Gene | Expression | Function |
|---|---|---|
| CALB1 | High | Calbindin D28k, calcium buffering |
| NTRK2 | High | BDNF receptor, synaptic plasticity |
| HTR2A | Moderate | Serotonin receptor |
| RGS14 | High | Learning and memory regulator |
| SLC17A6 | High | Vesicular glutamate transporter |
| GRIK1 | Moderate | Kainate glutamate receptor |
The study of Reuniens Nucleus (Re) Neurons has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
