IL4R

IL4R

A gene on chromosome 16p12.1-p11.2 that encodes the alpha chain of the IL4 receptor, a type-I transmembrane protein which can bind IL4 and IL13 to regulate IgE production. ILR4 also binds IL4 to promote differentiation of Th2 cells.

Molecular pathology
Allelic variants in IL4R have been associated with atopy, which is accompanied by allergic rhinitis, sinusitus, asthma and eczema, as well as by Japanese cedar pollinosis.

Secondary outcome measures include progression-free survival, overall survival, and exploratory predictors of outcome assessed by IL4R expression in archived tumor biopsies.
These results might further explain the beneficial effects exerted by miR-125b inhibition in SOD1-G93A microglia and motor neuron survival, thus suggesting that the neuroprotective effect exerted by miR125b inhibition might depend not only on the suppression of toxic mediators among which IL-1[beta] (Figure 2(a)), TNF[alpha], and NOX2 [19], but also on the direct stimulation of M2 parameters such as IL4R, Arg1, and BDNF in ALS microglia.
Asthma is believed to have a strong genetic background, and hundreds of genes have been identified to be related with asthma, including GSTM1, IL10, CTLA-4, SPINK5, LTC4S, IL4R, and ADAM33 [9].

To illustrate this, a 1362-bp fragment corresponding to a part of the IL4r gene from an individual heterozygous at six different positions was prepared by incorporation of R110-dUTP during PCR (31).
The genetic variants of pro-inflammatory cytokines (IL4, IL13, IL10, IL18, TNF, and IFNGR1), the cytokine receptor (IL4R), the genes involved in the IgE/Fc[epsilon]RI pathway (the galectin-3 gene (LGALS3)), and nucleotide-binding oligomerization domain (NOD) gene polymorphisms are also strongly associated with betalactam-induced immediate reactions (Table 2) [67-73].
