Unfortunately, the misrepresentative term “inhibition” was used in the penultimate paragraph of the above manuscript. The sixth sentence of this section should have read as follows: “The responsible signalling pathways are not fully understood, and could not only be related to transcriptional and post-transcriptional regulation of MKP-1 and calcium-mobilising second messengers [26], but also to altered transcription of proteins that are responsible for airway smooth muscle phenotype, including contractile elements, cytoskeleton, cell surface molecules, and cytokines or mediators with autocrine function [23, 27].” The authors apologise for this error.
