Type 2 inflammation in asthma can result in increased exacerbations and decreased lung function3


 

El asma alérgico está mediado por la respuesta inmune Tipo 23

IL-4 and IL-13 promote class switching of B cells to produce
IgE and play an important role in allergic inflammation in asthma3,5-7

Adapted from Froidure A et al, 2016,5
and Robinson D et al, 2017.3

IL-4 and IL-13 increase expression of the
high-affinity IgE receptor FcεRI, which results in
increased IgE/anti-IgE mediated histamine release7

Tipo 2 con roles

superpuestos.3

ILC2, type 2 innate lymphoid cells; TSLP, thymic stromal lymphopoietin.
