Task: Answer Verification
Input (English): Question: Do adult aortic valve interstitial cells have greater responses to toll-like receptor 4 stimulation?
Answer: Adult AVICs exhibit greater inflammatory and osteogenic responses to TLR4 stimulation. The enhanced responses in adult AVICs are at least partly due to lower levels of Stat3 activation in response to TLR4 stimulation relative to pediatric cells. Stat3 functions as a negative regulator of the TLR4 responses in human AVICs. The results suggest that Stat3 activation (tyrosine phosphorylation) may be protective and that TLR4 inhibition could be targeted pharmacologically to treat calcific aortic valve disease.
Output (English): yes
