Knockdown of PDPN in astrocytes reduces hippocampal inflammation in T2DM mice.

ABSTRACT:

Aims

Individuals with type 2 diabetes mellitus (T2DM) are at-risk for developing vascular dementia (VaD). Hyperglycemia leads to the activation of astrocytes. These activated cells produce proinflammatory mediators like cytokines or chemokines, that cause cerebrovascular damage. Previous sequencing showed Pdpn's high expression in activated stellate cells and possible inflammation involvement. Our study aims to reveal its role in T2DM-induced hippocampal inflammation in VaD.

Methods

Firstly, we will validate the expression of the Pdpn gene in T2DM astrocytes via qPCR and Western blot. Subsequently GFAP-specific promoter adeno-associated virus(AAV)carrying interfering sequence was used to knockdown the key gene in astrocytes of T2DM mice. Then the step-down test
