PKR regulates TLR2/TLR4-dependent signaling in murine alveolar macrophages.

abstract：:Extensive tissue remodeling occurs in survivors of acute lung injury, leading to nearly normal histology and physiology in the majority of individuals, whereas others suffer significant impairment due to the development of pulmonary fibrosis. Alveolar epithelial cells play a central role in the repair process. They ar...
