Targeting the Epigenetic Regulator CBX5 Promotes Fibroblast Metabolic Reprogramming and Inhibits Lung Fibrosis.

Idiopathic pulmonary fibrosis (IPF) is characterized by the sustained activation of interstitial fibroblasts leading to excessive collagen deposition and progressive organ failure. Epigenetic and metabolic abnormalities have been shown to contribute to the persistent activated state of scar-forming fibroblasts. However, how epigenetic changes regulate fibroblast metabolic responses to promote fibroblast activation and progressive fibrosis remains largely unknown.

Investigating the Triple Code Model in numerical cognition using stereotactic electroencephalography.

The ability to conceptualize numerical quantities is an essential human trait. According to the "Triple Code Model" in numerical cognition, distinct neural substrates encode the processing of visual, auditory, and non-symbolic numerical representations. While our contemporary understanding of human number cognition has benefited greatly from advances in clinical imaging, limited studies have investigated the intracranial electrophysiological correlates of number processing.
