In the majority of cases, tau pathology first appears in the memory centres of the brain, known as the entorhinal cortex and hippocampal formation. This has been shown to occur many years before patients have any symptoms of disease.
Within the hippocampal formation, the dentate gyrus plays a special role: it sits at the beginning of a trisynaptic circuit of memory formation, is necessary for encoding multiple inputs for contextual pattern separation [15-17], and supports adult neurogenesis.

The dentate gyrus is an anatomically and functionally well-characterized region of the mammalian hippocampal formation. Due to its position in the hippocampal circuitry, the dentate gyrus exerts control over the information flow and excitability in the hippocampal formation [1].

Explicit memory depends on intact fibers linking dentate granule cells with hippocampal pyramidal cells as well as pathways linking the hippocampal formation with other regions such as the frontal cerebral cortex.
Because we previously demonstrated in albino Swiss mice model of prion disease that astrocytes from the polymorphic layer of dentate gyrus exhibit intense reactive astrocytosis earlier than all other layers of dentate gyrus and that this change was associated with axonal degeneration of mossy fiber, we thought polymorphic layer and CA3 (target of mossy fibers) may exhibit the earliest astroglial pathology of the hippocampal formation of albino Swiss mouse model of prion disease.
Hippocampal formation, which plays a key role in the consolidation and retrieval of episodic and spatial memory, is among the brain structures most vulnerable to cerebral ischemia [4], and impaired hippocampal function is an important factor in the cognitive dysfunction of Alzheimer's disease (AD).
With respect to other receptors, these were generally low in EE, with the HTR3B gene pronounced in the olfactory bulb, hypothalamus, globus pallidus, hippocampal formation, and medulla.
