XBP-1s, alveolar macrophages and acquired inflammation in Cystic Fibrosis

immuno-oncology - macrophage v2 jpeg 2

While alveolar macrophages play an important role in the first line of defence against pathogens, they may also be involved in the chronic inflammatory state in cystic fibrosis (CF).

 

A recent study suggests that alveolar macrophages might contribute to CF hyper-inflammation through the X-box–binding protein-1 (XBP-1s) pathway. The up-regulation of XBP-1s mediates the secretion of inflammatory factors (cytokines) by alveolar macrophages.

 

This pathway could represent a new therapeutic target for CF, in combination with other therapies.
