Bovis calculus sativus (BCS) improves cognitive function after ischemic stroke by enhancing synaptic plasticity through the PKA/CREB/Sirt1/eIF2α pathway. This traditional agent shows potential for treating stroke-induced cognitive impairment.
Area of Science:
- Neuroscience
- Pharmacology
- Traditional Chinese Medicine
Background:
- Bovis calculus sativus (BCS) is a traditional agent with heat-clearing and cognitive-enhancing properties.
- It is used for ischemic stroke with cognitive impairment, but mechanisms require elucidation.
Purpose of the Study:
- To investigate BCS's therapeutic potential for ischemic stroke-induced cognitive impairment.
- To explore its mechanism involving synaptic plasticity and the PKA/CREB/Sirt1/eIF2α pathway.
Main Methods:
- Established a global cerebral ischemia/reperfusion (GCI/R) model in ICR mice.
- Assessed cognitive function using behavioral tests and analyzed hippocampal CA1 region histology.
- Quantified key protein expressions related to synaptic plasticity and signaling pathways via Western blot.
Main Results:
- BCS (10 and 15 mg/kg) significantly improved cognitive performance and preserved neuronal integrity.
- BCS upregulated p-PKA, CREB, and Sirt1, while suppressing the PERK/eIF2α pathway.
- This promoted synaptic remodeling, evidenced by increased PSD95 and SYN1 expression.
Conclusions:
- BCS enhances hippocampal synaptic plasticity via the PKA/CREB/Sirt1/eIF2α pathway.
- This mechanism promotes neuronal survival and improves cognitive function in ischemic stroke models.
- BCS demonstrates potential as a therapeutic agent for stroke-induced cognitive impairment.

Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
