Pathophysiology of ILD

{{{ Q01 }}}

{{{ Q02 }}}

IGF-binding protein 3 (IGFBP-3)

IGF-binding protein 5 (IGFBP-5)

Upregulation of Egr-1 (early growth response protein 1)

Regulates transforming growth factor (TGF)-β

Induction of syndecan-2 (SDC2)

Activation,proliferation, and migration of fibroblast to the site of injury

Fibroblasts

Altered PTEN (phosphatase and tensin homologue)/Akt axis

Acquire contractile stress fibres

Inactivates Fox (forkhead box) O3a

Protomyofibroblast,composed of cytoplasmic actins

Pleural mesothelial cells (PMCs)

Downregulation of cav-1 and Fas expression

De novo expression of α-SMA

TGF-β1-dependent mesothelial–mesenchymal transition

Fibroblast resistant to apoptosis

Myofibroblasts

Different ranges of contractions mediated by RhoA/Rho-associated kinase

Changes in intracellular calcium concentrations

Lock step mechanism of cyclic and contractile events

{{{ K04 }}}

Excess ECM production

Exerting traction force
