Does sTAT3-mediated astrogliosis protect myelin development in neonatal brain injury?
These results suggest that myelin development is regulated by a mechanism involving crosstalk between microglia and oligodendrocyte progenitors. Reactive astrocytes may modify this signaling in a STAT3-dependent manner, preventing the pathological expression of TGFβ-1 in microglia and the impairment of oligodendrocyte maturation.
CRT delivery at long term is feasible despite PS at the target LV site. PS management is mandatory in about 12.3% of patients at FU, with 6.6% remaining symptomatic. Symptoms improve at FU when a PS-LV>3V is achieved. Further improvement in lead manufacturing and pacing electronics are awaited to meet this clinical need.
