      Interleukin-13 (IL-13) is associated with the production of collagen in airway remodelling of asthma. Yet, the molecular mechanisms underlying IL-13 induction of collagen remain unclear; the aim of this study is to address this issue. IL-13 dose- and time-dependently-induced collagen I production in primary cultured airway fibroblasts; this was accompanied with the STAT6 phosphorylation, and pre-treatment of cells with JAK inhibitor suppressed IL-13-induced collagen I production. Further study indicated that IL-13 stimulated JAK/STAT6-dependent PDGF production and subsequent ERK1/2 MAPK activation in airway fibroblasts, and the presence of either PDGF receptor blocker or MEK inhibitor partially suppressed IL-13-induced collagen I production. Taken together, our study suggests that activation of JAK/STAT6 signal pathway and subsequent PDGF generation and resultant ERK1/2 MAPK activation mediated IL-13-induced collagen I production in airway fibroblasts.

      Forthcoming Special issue.

    • To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".

      Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.

      Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.

      Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
