Gut-Lung Dysbiosis Accompanied by Diabetes Mellitus Leads to Pulmonary Fibrotic Change through the NF-κB Signaling Pathway.

Growing evidence shows that the lungs are an unavoidable target organ of diabetic complications. However, the pathologic mechanisms of diabetic lung injury are still controversial. This study demonstrated the dysbiosis of the gut and lung microbiome, pulmonary alveolar wall thickening, and fibrotic change in streptozotocin-induced diabetic mice and antibiotic-induced gut dysbiosis mice compared with controls.

CNTF and Nrf2 Are Coordinately Involved in Regulating Self-Renewal and Differentiation of Neural Stem Cell during Embryonic Development.

There is high risk of fetal neurodevelopmental defects in pregestational diabetes mellitus (PGDM). However, the effective mechanism of hyperglycemia-induced neurodevelopmental negative effects, including neural stem cell self-renewal and differentiation, still remains obscure. Neuropoietic cytokines have been shown to play a vital part during nervous system development and in the coordination of neurons and gliocytes.

Negative impact of hyperglycaemia on mouse alveolar development.

Diabetes mellitus in pregnancy has been known to affect the embryonic development of various systems, including cardiovascular and nervous systems. However, whether this disease could have a negative impact on embryonic respiratory system remains controversial. In this study, we demonstrated that pregestational diabetes mellitus (PGDM)-induced defects in lung development in mice are mainly characterized by the changes in the morphological structure of the lung.
