Currently, there is scarce of evidence suggesting the relationship between motile cilia impairment and the development of pulmonary fibrosis, while several factors dysregulated in IPF have been reported to interfere ciliogenesis or ciliated cell differentiation, such as MMP7 (Yang et al., 2013; Gharib et al., 2013). The gene discussed is MMP7; the disease is pulmonary fibrosis.
