Randomized trial uncovers the role of the SDPR-STK38 axis in regulating alveolar type II cell behavior, suggesting new therapeutic approaches for lung repair.

Key Points

This research aims to understand how the SDPR-STK38 axis affects the balance between proliferation and differentiation in alveolar type II (AT2) cells.
Investigated the effects of SDPR and STK38 in mice and wild-type littermates after LPS-induced lung injury
Analyzed alveolar structure, AT2/AT1 composition, and lung function using histology and lung function tests
Conducted gain- and loss-of-function assays to study the regulation of GSK-3β/cyclin D1 signaling and Notch-Hes1-dependent differentiation.
Mice lacking SDPR exhibited more severe lung injury and worsened lung function compared to wild-type controls.
The SDPR-STK38 axis was found to regulate the proliferation-differentiation balance of AT2 cells through GSK-3β/cyclin D1 and Notch-Hes1 signaling.
SDPR deficiency led to excessive AT2 cell expansion and impaired differentiation into AT1 cells.
