Rather it seems that RELM quantity features a considerable function in the dynamics of repair, and one particular possibility is the fact that Ym1 is an vital regulator of RELM protein availability.Fig 7. RELM is required for rapid repair from the lungs following infection with N. brasiliensis.

For that reason, we examined the levels of lysyl hydroxylase within the lungs of mice following infection-induced injury in relation to Retnla expression. Expression of lysyl hydroxylase 2b (Lh2b) in the lungs of N. brasiliensis infected wild-type mice at day 4 and day six time points was enhanced relative to uninfected controls (Fig eight) coinciding with tissue repair (Fig 7). Quantification from the area of Lh2b staining revealed a significant reduction in the expression of Lh2b in Retnla +/- and -/- mice at dayFig 8. RELM regulates expression of lysyl hydroxylase 2b through lung repair.
