In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
Q: Context: Allergic airway inflammation is triggered by allergen exposure through several steps including release of IL-33, which promotes cytokine (IL-5, IL-13) production by type 2 innate lymphoid cells (ILC2s). MicroRNA (miR)-155 has recently been described to regulate adaptive responses in allergic inflammation. However, the role of miR-155 in the regulation of ILC2s remains unexplored.', 'We sought to elucidate the contribution of miR-155 in ILC2 expansion using experimental murine models of allergic airway inflammation.', 'To determine the role of miR-155 in the regulation of ILC2s in allergic airway inflammation, miR-155 deficient (miR-155', 'miR-155 was 10-fold upregulated in WT-derived ILC2s in response to IL-33. Furthermore, miR-155\Question: Is microRNA-155 a critical regulator of type 2 innate lymphoid cells and IL-33 signaling in experimental models of allergic airway inflammation?
A:
Our findings for the first time demonstrate that ILC2s and IL-33 signaling are regulated by miR-155 in allergicairway inflammation.
