Abstract The Interleukin-6 (IL-6) genetic polymorphism is associated with bronchial asthma,
a number of studies have been conducted to investigate the association between IL-6 gene …

Background Previous studies evaluated the association of IL-4 C33T polymorphism and risk
of bronchial asthma but failed to establish a consistent conclusive association. In the present …

There are controversies on the association between interleukin-13 (IL-13)+ 1923C/T
polymorphism (rs1295686) and the risk of asthma. We performed this study to assess the …

Background Associations between interleukin-13 (IL-13) polymorphisms and asthma risk
remained controversial and ambiguous. Therefore, we performed a meta-analysis to assess …

BACKGROUND AND AIMS: A large number of studies have investigated the correlation
between the interleukin (IL)-4 C-589T and C+ 33T polymorphisms and asthma susceptibility …

BACKGROUND: A number of studies assessed the association of− 589C/T polymorphism in
the promoter region of interleukin-4 (IL-4) with asthma in different populations. However, the …

Objective: The association between the interleukin 4 (IL-4) gene-33C/T polymorphism and
asthma risk is a subject of debate. We conducted a meta-analysis to evaluate the …

Objective: This meta-analysis aims to investigate whether interleukin-12B (IL-12B)−
1188A/C or the promoter polymorphisms may be a risk factor for asthma. Data Sources: Web …

Background Numerous investigations have previously evaluated the association of
interleukin (IL) 4 gene polymorphisms and the risk of asthma, conferring inconsistent results …

Asthma is a serious and hereditary respiratory disorder affecting all age groups. Interleukin-
13 (IL-13) is a central regulator of allergic inflammation. The purpose of the present study …
