Another study revealed that PFD might have the potential to reduce the generation of proinflammatory cytokines by stopping the action of p38 MAP Kinase in B lymphocytes, introducing a new potential in PFD for lung fibrosis, as migration and activation of fibroblasts can occur due to the inflammatory process started by B‐cell‐derived cytokines.53 Here, MAPK14 is linked to pulmonary fibrosis.
