Abstract
OBJECTIVE(S) This study aimed investigate association of HLA-DRB1 and cytokine polymorphisms with red blood cell(RBC) alloimmunization in Brazilian Myelodysplastic syndrome(MDS) patients with prior exposure to RBC transfusion. BACKGROUND MDS patients are at risk RBC alloimmunization due to chronic RBC transfusion. However, differences in immune response of MDS transfused patients are not completely known. METHODS/MATERIALS A retrospective cohort of 87 polytransfused patients with MDS including 28 alloimmunized (PA) and 59 non-alloimmunized (PNA) was evaluated in three Brazilian reference hospitals. HLA-DRB1genotype was performed by polymerase chain reaction (PCR)-SSOP (Luminex platform) and cytokine polymorphisms analysed by PCR and TaqMan assays. RESULTS While HLA-DRB1 allele frequencies did not differ between groups, IL17A 197G > A SNP and IL4 polymorphisms showed significant correlation with RBC alloimmunization. IL17A 197A allele A and AA genotype were significantly more frequent in PA than PNA(A, 46.4% versus 27.1%, p = 0.012; OR = 2.3; 95%CI = 1.1-4.9; AA, 25% versus 6.8%, p = 0.041; OR = 6.2; 95%CI 1.3-30.8). Moreover, significant association of alloimmunization to Rh antigens with IL17A 197A allele and AA genotype was also identified in PA group(A, 45% versus 27.1%, p = 0.036; OR = 2.5; 95% CI 1.1-5.7; AA, 30% versus 6.8%, p = 0.042; OR = 7.9; 95%CI 1.5-42.3). Genotype A1A2 of IL4 intron 3 was overrepresented in PA(50% versus 16.9%, p = 0.009; OR = 4.97; 95%CI 1.6-15.5). Similarly, IL4-590 CT genotype was overrepresented in PA(53.6% versus 28.8%, p = 0.049; OR = 3.3; 95%CI 1.2-9.3). CONCLUSIONS This study showed no association regarding HLA-DRB1 alleles for RBC alloimmunization risk or protection, however the IL17A 197G>A, IL4 intron 3 and IL4 590C>T SNP was significantly associated to RBC alloimmunization risk in this cohort of Brazilian MDS patients.

Abstract
Backgrounds Breast cancer (BC) is one of the most widespread cancers globally. Understanding the etiology of BC may help in determining the various risk factors involved in its malignancy. Certain genetic mutations are considered to play a key role in increasing the risk of BC. Objectives In this study, we explored the correlation between a variable number tandem repeat (VNTR) polymorphism in the IL-4 gene and BC. Methods PCR and subsequent gel electrophoresis were used to genotype this variant in 360 Jordanian women (180 BC patients and 180 controls). In addition, phenotype–genotype analysis was carried out. Results Our findings illustrate that there is no significant relationship between the variant genotypes in the IL-4 gene and BC among Jordanian females. Other than body mass index and tumor differentiation (p< 0.05), none of the clinical and pathological parameters of BC patients exhibited any association with the variant genotypes. Conclusions From this study, we propose that the IL-4 genetic variant does not impact BC development and progression but that it could influence the disease prognosis.

[PMID: 28615046 PMCID: PMC5471687 DOI: 10.1186/s40101-017-0142-x] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2017] [Accepted: 06/01/2017] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Despite the fact that insertions/deletions (INDELs) are the second most common type of genetic variations and variable number tandem repeats (VNTRs) represent a large portion of the human genome, they have received far less attention than single nucleotide polymorphisms (SNPs) and larger forms of structural variation like copy number variations (CNVs), especially in genome-wide association studies (GWAS) of complex diseases like polygenic obesity. This is exemplified by the vast amount of review papers on the role of SNPs and CNVs in obesity, its related traits (like anthropometric measurements, biochemical variables, and eating behavior), and its related complications (like hypertension, hypertriglyceridemia, hypercholesterolemia, and insulin resistance-collectively known as metabolic syndrome). Hence, this paper reviews the types of INDELs and VNTRs that have been studied for association with obesity and its related traits and complications. These INDELs and VNTRs could be found in the obesity loci or genes from the earliest GWAS and candidate gene association studies, like FTO, genes in the leptin-proopiomelanocortin pathway, and UCP2/3. Given the important role of the brain serotonergic and dopaminergic reward system in obesity susceptibility, the association of INDELs and VNTRs in these neurotransmitters' metabolism and transport genes with obesity is also reviewed. Next, the role of INS VNTR in obesity and its related traits is questionable, since recent large-scale studies failed to replicate the earlier positive associations. As obesity results in chronic low-grade inflammation of the adipose tissue, the proinflammatory cytokine gene IL1RA and anti-inflammatory cytokine gene IL4 have VNTRs that are implicated in obesity. A systemic proinflammatory state in combination with activation of the renin-angiotensin system and decreased nitric oxide bioavailability as found in obesity leads to endothelial dysfunction. This explains why VNTR and INDEL in eNOS and ACE, respectively, could be predisposing factors of obesity. Finally, two novel genes, DOCK5 and PER3, which are involved in the regulation of the Akt/MAPK pathway and circadian rhythm, respectively, have VNTRs and INDEL that might be associated with obesity. SHORT CONCLUSION In conclusion, INDELs and VNTRs could have important functional consequences in the pathophysiology of obesity, and research on them should be continued to facilitate obesity prediction, prevention, and treatment.

Abstract
Background & objectives: Interleukin-1 (IL-1) is one of the pro-inflammatory cytokines that plays a main role in the regulation of immune and inflammatory responses. Interleukin 4 (IL-4) as an anti-inflammatory cytokine regulates balance between Th1 and Th2 immune responses. This study was undertaken to investigate the IL-1β and IL-4 genes polymorphisms in patients with systemic lupus erythematosus (SLE) and also association between the polymorphisms and susceptibility to SLE. Methods: One hundred and sixty three SLE patients and 180 healthy controls were genotyped for the IL-4 VNTR (variable number tandem repeat), IL-1β C-511T and IL-1β T-31C polymorphisms by polymerase chain reaction (PCR) or PCR-RFLP (restriction fragment length polymorphism) method. Results: The frequencies of CC genotype and C allele of the IL-1β T-31C polymorphism were significantly (P<0.01) lower in SLE patients than controls. Moreover, the frequencies of RP1/RP2 genotype and RP2 allele of IL-4 VNTR polymorphism were significantly (P<0.05) higher in the SLE patients. No association was observed between IL-1β C-511T polymorphism and increased risk of SLE. We observed increased frequency of CT and TT genotypes of IL-1β C-511T polymorphism in SLE patients with malar rash compared to SLE patients without this manifestation. Interpretation & conclusions: The present findings suggest that IL-1β T-31C and IL-4 VNTR polymorphisms but not IL-1β C-511T polymorphism may contribute in SLE pathogenesis. In addition, CT and TT genotypes of IL-1β C-511T polymorphism were associated with SLE.

Abstract
Interleukin-1 receptor antagonist (IL1RA) intron 2 86 bp repeat and interleukin-4 (IL4) intron 3 70 bp repeat are variable number tandem repeats (VNTRs) that have been associated with various diseases, but their role in obesity is elusive. The objective of this study was to investigate the association of IL1RA and IL4 VNTRs with obesity and adiposity in 315 Malaysian subjects (128 M/187 F; 23 Malays/251 ethnic Chinese/41 ethnic Indians). The allelic distributions of IL1RA and IL4 were significantly different among ethnicities, and the alleles were associated with total body fat (TBF) classes. Individuals with IL1RA I/II genotype or allele II had greater risk of having higher overall adiposity, relative to those having the I/I genotype or I allele, respectively, even after controlling for ethnicity [Odds Ratio (OR) of I/II genotype = 12.21 (CI = 2.54, 58.79; p = 0.002); II allele = 5.78 (CI = 1.73, 19.29; p = 0.004)]. However, IL4 VNTR B2 allele was only significantly associated with overall adiposity status before adjusting for ethnicity [OR = 1.53 (CI = 1.04, 2.23; p = 0.03)]. Individuals with IL1RA II allele had significantly higher TBF than those with I allele (31.79 ± 2.52 versus 23.51 ± 0.40; p = 0.005). Taken together, IL1RA intron 2 VNTR seems to be a genetic marker for overall adiposity status in Malaysian subjects.

Abstract
BACKGROUND The reason for the difference in susceptibility to red blood cell (RBC) alloimmunization among patients with sickle cell disease (SCD) is not clearly understood and is probably the result of multiple factors. Our hypothesis is that genetic polymorphisms are associated with RBC alloimmunization. STUDY DESIGN AND METHODS We investigated the possible association of susceptibility to RBC alloimmunization with polymorphisms of HLA and cytokines genes in 161 SCD patients prior exposed to RBC transfusion. Cytokine gene polymorphisms were analyzed by polymerase chain reaction (PCR) and TaqMan assays. HLA Class I genotyping was performed using PCR-specific sequence of oligonucleotides. Polymorphism frequencies were compared using the Fisher's exact test. RESULTS Our results revealed increased percentage of the A allele and the GA genotype of the TNFA -308G/A cytokine among alloimmunized patients when compared to nonalloimmunized patients (A allele, 16.4% vs. 6.8%, p = 0.004; GA genotype, 32.8% vs. 11.7%, p = 0.0021). In addition, the IL1B -511T allele and the IL1B -511TT and CT genotype frequencies were overrepresented among alloimmunized patients (T allele, 53.0% vs. 37.5%, p = 0.0085; CT + TT genotypes, 81.82% vs. 60.87%, p = 0.0071). In relation to HLA Class I, we found a higher frequency of HLA-DRB1*15 among patients alloimmunized to Rh antigens when compared to nonalloimmunized patients (15.63% vs. 6.98%, p = 0.044). CONCLUSION Brazilian SCD patients with the TNFA, IL1B, and HLA-DRB1 gene polymorphisms were at increased risk of becoming alloimmunized by RBC transfusions. These findings may contribute to the development of future therapeutic strategies for patients with SCD with higher susceptibility of alloimmunization.

Abstract
Diabetic polyneuropathy and cardiovascular autonomic neuropathy are common and disabling complications of diabetes. Although glycaemic control and cardiovascular risk factors are major contributory elements in its development, diabetic neuropathy recognizes a multifactorial influence and a multiplicity of pathogenetic mechanisms. Thus genetic and environmental factors may contribute to its susceptibility, each with a modest contribution, by targeting various metabolic and microvascular pathways whose alterations intervene in diabetic neuropathy pathogenesis. This review is aimed at describing major data from the available literature regarding genetic susceptibility to diabetic neuropathies. It provides an overview of the genes reported as associated with the development or progression of these complications, i.e. ACE, MTHFR, GST, GLO1, APOE, TCF7L2, VEGF, IL-4, GPX1, eNOS, ADRA2B, GFRA2, MIR146A, MIR128A. The identification of genetic susceptibility can help in both expanding the comprehension of the pathogenetic mechanisms of diabetic nerve damage and identifying biomarkers of risk prediction and response to therapeutic intervention.

Abstract
OBJECTIVE Immune thrombocytopenic purpura (ITP) is an acquired autoimmune disorder caused by the production of antiplatelet antibodies. These autoantibodies opsonize platelets for splenic clearance, resulting in low levels of circulating platelets. Interleukin 4 (IL4) and interleukin 10 (IL10) are important immunoregulatory cytokines mainly produced by macrophages, monocytes, T cells, B cells, and mast cells. Our study was aimed at detecting the frequency of IL4 (VNTR intron 3) and IL 10 (-627) gene polymorphisms in Egyptian ITP children as genetic markers for ITP risk and clarifying their possible role in the pathogenesis of ITP as well as their correlation with the clinical presentation and laboratory data. METHODS IL4 (VNTR intron 3) and IL10 (-627) gene polymorphisms were studied in 70 ITP patients and 50 age- and sex-matched healthy controls using polymerase chain reaction-restriction fragment length polymorphism assay (PCR-RFLP). RESULTS IL4 RP2 and IL10 A alleles were detected more frequently among ITP patients compared to controls. A statistically significant difference was observed in IL10 and IL4 gene polymorphism distribution between acute and chronic ITP patients, with higher A allele and RP2 allele among chronic ITP patients versus acute ITP patients. Combined polymorphisms of IL4 and IL10 genes were associated with greater risk of ITP. CONCLUSION IL4 and IL10 gene polymorphisms may contribute to susceptibility for ITP in children.

Abstract
Autoimmune thyroid diseases (AITD) including Graves' disease (GD) and Hashimoto's thyroiditis (HT) are complex genetic diseases. Cytokines IL-1B and IL-4 play a role in the pathogenesis of AITD. This study was conducted on Tunisian patients with GD or HT to investigate the association of IL-1B and IL-4 gene polymorphisms with the risk and the prognosis of AITD. A total of 358 healthy controls and 341 patients with AITDs (249 HT and 92 GD) were genotyped for IL-1B+3953C/T and IL-4 intron 3 VNTR polymorphisms. A significant association was found between IL-1B+3953C/T polymorphism and GD or HT, both in the dominant and additive models. The IL-1B+3953T allele was associated with GD (p = 0.0003, OR = 1.93, CI = 1.34-2.78) and HT (p = 0.009, OR = 1.43, CI = 1.09-1.88). The IL-4 VNTR polymorphism was associated only with HT risk both in additive (p = 0.03, OR = 0.31, CI = 0.11-0.86) and recessive (p = 0.03, OR = 3.04, CI = 1.13-8.17) models. No significant association was found between IL-1B+3953C/T polymorphism and change in the serum concentrations of TSH and FT4 in GD and HT patients. In HT patients, the IL-1B+3953T allele (p = 0.009, OR = 0.42, CI = 0.22-0.83) and the IL-1B+3953T/T genotype (p = 0.03, OR = 0.21, CI = 0.04-1.07) were more frequent in the absence than in the presence of an anti-TPO antibody. The proportion of HT patients with the P1P2 genotype of the IL-4 gene was significantly higher in the absence than in the presence of the anti-TPO antibody (p = 0.04, OR = 0.39, CI = 0.17-0.89). These preliminary results suggest that IL-1B and IL-4 gene polymorphisms may be associated with GD and HT susceptibility and may represent prognostic factors for predicting the severity of HT.

Systemic lupus erythematosus (SLE) represents a challenging autoimmune disease from a clinical perspective because of its varied forms of presentation. Although broad-spectrum steroids remain the standard treatment for SLE, they have many side effects and only provide temporary relief from the symptoms of the disease. Thus, gaining a deeper understanding of the genetic traits and biological pathways that confer susceptibility to SLE will help in the design of more targeted and effective therapeutics. Both human genome-wide association studies (GWAS) and investigations using a variety of mouse models of SLE have been valuable for the identification of the genes and pathways involved in pathogenesis. In this Review, we link human susceptibility genes for SLE with biological pathways characterized in mouse models of lupus, and discuss how the mechanistic insights gained could advance drug discovery for the disease.

Abstract
Background Interleukin-4 (IL-4) is best known as an important mediator and modulator of immune and inflammatory responses. Hepatocellular carcinoma (HCC) is a typical inflammation-related cancer, and genetic variations in the IL-4 gene may be associated with the risk of hepatitis B virus (HBV)-related HCC. However, few studies have been conducted on their association. Objectives To clarify the effects of IL-4 gene polymorphisms on the risk of HBV-related HCC, two common variants, −590C/T (rs2243250) and −33C/T (rs2070874), and their relationship with HBV-related disease risk were investigated in a Chinese population. Methods IL-4 −590C/T and −33C/T polymorphisms were examined in 154 patients with HBV-related HCC, 62 patients with HBV-induced liver cirrhosis (LC), 129 patients with chronic hepatitis B (CHB), and 94 healthy controls, using the polymerase chain reaction-restriction fragment length polymorphism method and DNA sequencing. Results Overall, no significant differences were observed regarding the IL-4 −590C/T and −33C/T polymorphism genotypes, alleles, or haplotypes between the patient groups and the healthy controls. However, the CC genotypes of IL-4 −590C/T and −33C/T polymorphisms were observed to be significantly associated with CHB in subgroup analysis in males [CC versus TT (OR: 4.193, 95% CI: 1.094–16.071, P = 0.037; and OR: 3.438, 95% CI: 1.032–11.458, P = 0.044) and CC versus TT+CT (OR: 4.09, 95% CI: 1.08–15.49, P = 0.038; and OR: 3.43, 95% CI: 1.04–11.28, P = 0.042)]. Conclusions These findings suggest that genetic variants in IL-4 −590C/T and −33C/T polymorphisms may be a risk factor for CHB in Chinese males but not for HBV-related LC or HCC.

Abstract
Preeclampsia (PE) is a pregnancy-specific disorder that results in maternal mortality and morbidity. Growing evidence indicated that cytokines are involved in the pathogenesis of PE and interleukin-4 VNTR polymorphism could be implicated in altering the PE risk. The aim of this study was to evaluate the possible association between IL-4 VNTR polymorphism and susceptibility to PE in Iranian population for the first time. Genetic polymorphism was evaluated in 192 PE and 186 healthy control women by polymerase chain reaction method. We found that the VNTR polymorphism of IL-4 gene has significantly increased the risk of preeclampsia (RP2/RP1 versus RP1/RP1, OR, 2.8 [95% CI, 1.7 to 8.8]; P = 0.0001 and RP2/RP2 versus RP1/RP1; P = 0.002). The results showed that carriage of IL-4 VNTR RP2 allele has positive association with preeclampsia susceptibility.

Abstract
OBJECTIVE Studies investigating the association between interleukin (IL)-4 gene promoter -590C/T (rs2243250) polymorphism and autoimmune diseases report conflicting results. To derive a more precise estimation of the relationship, a meta-analysis was performed. METHODS A systematic literature search was conducted to identify relevant studies. Pooled odds ratio (OR) with 95% confidence interval (CI) was used to estimate the strength of association. RESULTS A total of 6001 cases and 6788 controls from 24 studies were analysed. Significant association of the C allele of IL-4 rs2243250 polymorphism with rheumatoid arthritis (RA) was detected (odds ratio (OR) = 0.696, 95% confidence interval (CI) = 0.601-0.807). Stratification by ethnicity indicated an association between the IL-4 rs2243250 polymorphism and RA in Caucasians. Furthermore, the overall ORs of the associations between the C allele and multiple scleorosis (MS) were 1.340 (95% CI = 1.102-1.630). However, we failed to reveal any association between IL-4 rs2243250 polymorphism and systemic lupus erythematosus (SLE), type 1 diabetes (T1D) or Graves' disease (GD). CONCLUSIONS The present study suggests that the IL-4 rs2243250 polymorphism might be associated with genetic susceptibility to autoimmune diseases, including RA and MS.

Abstract
BACKGROUND A case-control study was conducted to evaluate the role of IL-4 VNTR polymorphism in asthma that has been associated with various inflammatory diseases worldwide. This is the first case-control study conducted in India, investigating the role of IL-4 VNTR polymorphism in asthma pathogenesis. METHODS A case-control study was performed with a total of 824 adult subjects, inducting 410 asthma patients and 414 healthy controls from North India. The genotypes were identified by polymerase chain reaction. RESULTS Statistical analysis for the IL-4 VNTR polymorphism revealed that the Rp1 allele was significantly associated with asthma with OR=1.47, 95% CI (1.11-1.94) and p=0.005. The Rp1/Rp1 homozygous mutant genotype posed a high risk towards asthma with OR=2.39, 95% CI (0.96-6.14) and p=0.040. The Rp2/Rp1 heterozygous genotype also posed a risk towards asthma with OR=1.39, 95% CI (1.00-1.94) and p=0.040. Most of the phenotypic traits were significantly associated with the disease. CONCLUSIONS IL-4 VNTR polymorphism is a high risk factor for asthma in the studied North Indian population.

Abstract
OBJECTIVE Interleukin-4 (IL-4) is a strong chondroprotective cytokine and polymorphisms within this gene may be a risk factor for osteoarthritis (OA). We aimed to investigate genotype and allele frequencies of IL-4 gene intron 3 variable number of tandem repeats (VNTR) polymorphism in patients with knee OA in a Turkish population. METHODS The study included 202 patients with knee OA and 180 healthy controls. Genomic DNA was isolated and IL-4 gene 70 bp VNTR polymorphism determined by using polymerase chain reaction (PCR) with specific primers followed by restriction fragment length polymorphism (RFLP) analysis. RESULTS Our result show that there was statistically significant difference between knee OA patients and control group with respect to IL-4 genotype distribution and allele frequencies (p=0.000, OR: 0.20, 95% CI: 0.10-0.41, OR: 0.22, 95% CI: 0.12-0.42, respectively). CONCLUSIONS Our findings suggest that there is an association of IL-4 gene intron 3 VNTR polymorphism with susceptibility of a person for development of knee OA. As a result, IL-4 gene intron 3 VNTR polymorphism could be a genetic marker in OA in a Turkish study population. This is the first association study that evaluates the associations between IL-4 gene VNTR polymorphism and knee OA.

Abstract
OBJECTIVE Interleukin (IL)-4 is a key cytokine in humoral and adaptive immunity. This study aimed to evaluate the association of IL-4 genetic variants (-590C>T and VNTR in intron 3) with the risk and prognosis of oral and pharyngeal squamous cell carcinoma (OPSCC). DESIGN A total of 1215 subjects, which included 623 healthy controls and 592 OPSCC cases (463 oral squamous cell carcinoma (OSCC) and 129 pharyngeal squamous cell carcinoma (PSCC) cases), were recruited. The genotypes were determined by TaqMan real-time assay and PCR-based assay. RESULTS The IL-4 genotypes at locus -590C>T and intron 3 VNTR were not correlated with increased risk of OSCC, PSCC, and OPSCC, with the exception of early-stage OPSCC (at -590C>T: T/T vs. C/C+C/T, adjusted odds ratio (AOR)=1.42, 95% CI: 1.02-1.98; at intron 3 VNTR: RP1/RP1 vs. RP2/RP2+RP2/RP1, AOR=1.46, 95% CI: 1.05-2.04). Compared with other IL-4 diplotypes, the T,RP1/T,RP1 diplotype was associated with an increased risk of OPSCC (AOR=1.37, 95% CI: 1.03-1.81), particularly early-stage OSCC (AOR=1.43, 95% CI: 1.02-2.00), PSCC (AOR=2.35, 95% CI: 1.06-5.19), and OPSCC (AOR=1.52, 95% CI: 1.10-2.11). Interactions between the IL-4 diplotype and the alcohol drinking status were found to contribute to the risk of early-stage OPSCC (p=0.024). In addition, the T,RP1/T,RP1 diplotype was correlated with better disease-specific survival (T,RP1/T,RP1 vs. other diplotypes, adjusted hazard ratio=0.70, 95% CI: 0.50-0.97). CONCLUSION The T, RP1/T, RP1 diplotype of IL-4 was associated with an increased risk but favourable prognosis of OPSCC.

Abstract
Diabetic peripheral neuropathy (DPN) is a common disease. It is one of the late complications of diabetes mellitus. DPN can lower the quality of life by causing severe painful clinic symptoms. The aim of this study is to evaluate interleukin (IL)-4 gene variable number of tandem repeat (VNTR) polymorphism on DPN in Turkish population. Two hundred and twenty-seven DPN patients and 241 controls were enrolled in this study. Genomic DNA was isolated and genotyped using polymerase chain reaction analyses for the IL-4 gene intron 3 VNTR polymorphism. The distribution of genotype frequencies of IL-4 gene intron 3 VNTR polymorphism was statistically different between DPN patients and control group (p = 0.001). The frequency of P1 and P2 alleles was statistically different between DPN patients and control group (p = 0.00009). The results of this study suggested that intron 3 VNTR polymorphism of the IL-4 gene plays an important role in the occurrence of DPN in the Turkish population.

Abstract
OBJECTIVE Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosal diseases, with a multifactorial etiopathogenesis, an interaction between predisposing factors and/or systemic conditions and immunological components in genetically predisposed subjects. Although there is no clear genetic mode of inheritance, there is evidence that inheritance of specific gene polymorphisms may predispose individuals to RAS. The purpose of the present study was to investigate a possible association between the functional interleukin 4 (IL4) VNTR genetic polymorphism and RAS in a sample of Turkish patients. METHODS The study included 145 unrelated patients with a clinical diagnosis of RAS and 150 unrelated healthy controls. Genomic DNA was isolated and IL4 gene 70 bp VNTR polymorphism determined by using polymerase chain reaction (PCR) with specific primers. RESULTS The distribution of genotype and allele frequencies of IL4 gene intron 3 VNTR polymorphism was statistically different between RAS patients and control group (p<0.0001 and p<0.0001, respectively) P2P2 genotype and P2 allele were also found to be protective with a lower risk for susceptibility to RAS (p<0.0001). CONCLUSION The results of this study suggest that intron 3 VNTR polymorphism in the IL4 gene is associated with RAS susceptibility in Turkish population.

Abstract
OBJECTIVE Genetic risk factors are known to contribute to the etiology of multiple sclerosis (MS). Interleukin (IL)-4 gene polymorphisms have been associated with immune-mediated diseases. The aim of this study was to explore the frequency of IL-4 gene intron 3 VNTR (variable number tandem repeat) polymorphism in a cohort of Turkish patients with MS. METHODS The study included 125 patients with MS and 160 healthy controls. Genomic DNA was isolated and genotyped using polymerase chain reaction (PCR) analyses for the IL-4 gene intron 3 VNTR polymorphism. RESULTS The distribution of genotype and allele frequencies of IL-4 gene intron 3 VNTR polymorphism was statistically different between MS patients and control group (p = 0.003 and p = 0.002, respectively). There were no statistically significant association between IL-4 VNTR polymorphism and clinical and demographical characteristics of MS patients. CONCLUSION The results of this study suggest that intron 3 VNTR polymorphism of the IL-4 gene was positively associated with predisposition to develop MS in Turkish population.

Abstract
Rheumatoid arthritis (RA) is a chronic, systemic inflammatory disease that mainly affects the joints. Polymorphic variations of the cytokine genes and MTHFR gene have received attention as potential markers of susceptibility, severity, and/or protection in RA. The aim of this study was to investigate the MTHFR C677T and IL-4 70bp VNTR variation in Turkish patients with RA and evaluate if there was an association with clinical features, especially ocular involvement, in RA patients. The study included 297 persons (147 patients with RA and 150 healthy controls). Genomic DNA was isolated and genotyped using PCR assay for the MTHFR gene C677T and IL-4 gene 70bp VNTR polymorphisms. Our results show that there was statistically significant difference between the groups with respect to IL-4 genotype (p=0.01) and allele frequencies (p<0.002). There was no statistical significant difference in the genotype frequencies MTHFR gene, but allele frequencies showed statistically significant association (p=0.01). When we examined MTHFR and IL-4 genotype frequencies according to the clinical characteristics, we found that there was a difference between MTHFR genotypes and ocular involvement but it is not to a statistical significant degree (p=0.09). In the combined genotype analysis, MTHFR/IL-4 CCP2P2 combine genotype was estimated to have protective effect against RA, CTP1P2 combine genotype was found to be risk for RA. Our findings suggest that there is an association of IL-4 gene 70bp VNTR polymorphism and MTHFR C677T polymorphism with susceptibility of a person for development of RA.

Abstract
OBJECTIVES Cervical cancer is rated the second most common malignant tumor globally and is etiologically linked to human papillomavirus infection. Interleukin-4 (IL-4) and IL-10 are cytokines with anti-inflammatory properties. The purpose of this study was to determine the relationship of different alleles of IL-4 and IL-10 genes with risk of cervical cancer among passive smokers and users of oral contraceptives. MATERIALS AND METHODS We investigated the association of cervical cancer with 2 anti-inflammatory cytokine genes IL-4 and IL-10 using a case-control study. The study sample comprised 200 cases of cervical cancer and an equal number of matched controls who were investisgated by variable number of tandem repeat and Restriction Fragment Length Polymorphism analysis. RESULTS In this study we observed that the Rp1/Rp2 genotype of IL-4 marginally increased the risk of developing cervical cancer [odds ratio (OR), 1.3; 95% confidence intervals (CI), 0.45-3.64; P=0.8]. In case of passive smokers we also found a marginal increase in the risk for cervical cancer with AC and combined AC+CC genotypes (OR, 1.7; 95% CI, 0.90-3.34; P=0.1; and OR,1.7; 95% CI, 0.90-3.17; P=0.1, respectively). However, a nonsignificant association was observed between use of oral contraceptives and risk of cervical cancer with anti-inflammatory cytokine genotypes. CONCLUSIONS This study suggests that passive smokers among North Indian women having IL-4 Rp1/Rp2 and IL-10 (AC) genotypes had an increased risk for developing cervical cancer.

Abstract
BACKGROUND Vitiligo is an acquired pigmentary disorder resulting from loss of melanocytes. Interleukin (IL)-4 has been shown to stimulate B-cell proliferation, to regulate immunoglobulin class switching (IgG1 and IgE) and to promote T-cell development. Polymorphisms in the IL4 gene are known to increase its expression, thereby implicating its role in vitiligo susceptibility. OBJECTIVES To explore intron 3 VNTR (IVS3) and -590 C/T (rs2243250) promoter polymorphisms in the IL4 gene and to correlate them with the IL4 transcript, serum IL-4 and IgE levels to achieve genotype-phenotype correlation in patients with vitiligo from Gujarat. A replication study was done in a North Indian population. METHODS The case-control study was performed to investigate these polymorphisms in 505 patients and 744 controls in Gujarat, and 596 patients and 397 controls in North India by polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism analysis. IL4 transcript levels were monitored by real-time PCR. Serum IL-4 and IgE levels were measured by enzyme-linked immunosorbent assay and electrochemiluminescence immunoassay, respectively. RESULTS The genotype frequencies differed significantly between patients with generalized vitiligo and controls for both the polymorphisms in both populations. Allele frequencies significantly differed between patients with generalized vitiligo and controls for both the polymorphisms in the population from Gujarat. Interestingly, genotype and allele frequencies for -590 C/T single nucleotide polymorphism were significantly different between patients with localized vitiligo and controls in both the populations. The study revealed significantly increased IL4 mRNA, serum IL-4 and IgE levels in patients from Gujarat. Age of onset analysis of disease in patients suggested that the TTR2R2, TTR1R2 and CTR2R2 haplotypes had a profound effect in the early onset of the disease. CONCLUSIONS Our results suggest that these polymorphisms of the IL4 gene may be genetic risk factors for susceptibility towards vitiligo and the upregulation of the IL4 transcript, protein and IgE levels in individuals with susceptible haplotypes reveal the crucial role of IL-4 in the pathogenesis of vitiligo.

Abstract
BACKGROUND AND OBJECTIVES Immune system-related factors are important in the pathogenesis of multiple sclerosis (MS). Interleukin 4 (IL-4) as a helper T cell (2TH) cytokine is involved in the regulation of immune responses. Hence, this study was designed to explore the association between MS and polymorphisms in the -590 region of IL-4. DESIGN AND SETTING A descriptive study at Rafsanjan University of Medical Sciences, Rafsnajan from September 2009 to August 2010. PATIENTS AND METHODS Blood samples were collected from 100 MS patients and 150 healthy controls on EDTA precoated tubes. DNA was extracted and analyzed for IL-4 polymorphisms using restricted fragment length polymorphism in patients and controls. Demographic data were also collected by a questionnaire that was designed specifically for this study. RESULTS We observed a significant difference in the C/C, T/C, and T/T genotypes of the -590 region of IL-4 between patients with MS and healthy controls (P<.001). CONCLUSIONS We conclude that functional polymorphisms of IL-4 possibly play a crucial role in the pathogenesis of MS.

Abstract
SLE is an autoimmune disease that is not uncommon in Malaysia. In contrast to Malays and Indians, the Chinese seem to be most affected. SLE is characterized by deficiency of body's immune response that leads to production of autoantibodies and failure of immune complex clearance. This minireview attempts to summarize the association of several candidate genes with risk for SLE in the Malaysian population and discuss the genetic heterogeneity that exists locally in Asians and in comparison with SLE in Caucasians. Several groups of researchers have been actively investigating genes that are associated with SLE susceptibility in the Malaysian population by screening possible reported candidate genes across the SLE patients and healthy controls. These candidate genes include MHC genes and genes encoding complement components, TNF, FcγR, T-cell receptors, and interleukins. However, most of the polymorphisms investigated in these genes did not show significant associations with susceptibility to SLE in the Malaysian scenario, except for those occurring in MHC genes and genes coding for TNF-α, IL-1β, IL-1RN, and IL-6.

Abstract
AIM Colorectal cancer is associated with inflammatory bowel disease. The mechanisms of how different genetic make-ups of cytokines might influence the individual susceptibility to develop particular types of tumours are still unknown. The authors analysed the association between genetic polymorphisms in cytokine/cytokine receptor genes and the risk of colorectal cancer in a Korean population. METHOD The authors assessed polymorphisms of the interleukin: IL-1, IL-1R, IL-2, IL-4, IL-4R, IL-10, transforming growth factor (TGF)-β1, IFN-γ genes in Korean patients with colorectal cancer (n = 170) and in a normal healthy control group (n = 130) to investigate the association between theses cytokine gene polymorphisms and the risk of colorectal cancer. RESULTS The IL-4R 1902*T allele was found to be associated with an increased risk of colon cancer (P < 0.01, OR = 2.0) and rectal cancer (P < 0.05, OR = 1.8). The IL-4R 1902*C allele was associated with a decreased risk of both colon cancer (P < 0.01, OR = 0.51) and rectal cancer (P < 0.05, OR = 0.5). The TFG-β1 10*T allele was found to be associated with an increased risk of colon cancer (P < 0.00, OR = 2.3) and the TFG-β1 10*C allele with a decreased risk of colon cancer (P < 0.00, OR = 0.43). CONCLUSION These results suggest that the genetic polymorphisms of IL-4R and TGF-β1 are associated with the risk of colorectal cancer in a Korean population.

Abstract
An imbalance between T Helper 1 (TH1) and T Helper 2 (TH2) cytokine production is important for the pathogenesis of systemic lupus erythematosus (SLE). We aimed to investigate gene—gene associations of TH1 and TH2 cytokines genes in Chinese patients with SLE. Twenty single nucleotide polymorphisms (SNPs) in eight cytokines genes were genotyped in 110 SLE patients and 138 healthy controls in a case—control association study. The minor allelic frequencies of interleukin4(IL4) -590 T/C, -33 T/C, 9241C/G, and IL10 -592 A/C were significantly increased in SLE patients compared with those in controls (p < 0.05). None of the separate 20 SNPs showed significant association with SLE after Bonferroni correction. An IL4 haplotype -590C/-33C/9241G/14965C was significantly associated with SLE (odds ratio 3.7, 95% confidence interval [CI] 1.5—8.9, p = 0.004, Bonferroni-corrected p = 0.024). A borderline significant three-locus gene—gene interaction among IL4 9241 C/G, IL4 -33 T/C, signal transducer and activator of transcription 6, IL4-induced (STAT6) 2892 C/T was detected by a multifactor dimensionality reduction test (p = 0.051). However, the presence of two at-risk genotypes lead to increased risk of SLE for two-locus interaction using logistic regression method. The risk of SLE increased significantly when a subject has two at-risk genotypes for IL4 -590C and STAT6 2892C (odds ratio, 3.24, 95% CI 1.5—7.0, p = 0.003, Bonferroni-corrected p = 0.009), IL4 -33C and STAT6 2892C (odds ratio 3.06, 95% CI 1.4— 6.7, p = 0.005, Bonferroni-corrected p = 0.015), as well as IL4 9241G and STAT6 2892C (odds ratio 3.34, 95% CI 1.6—7.1, p = 0.002, Bonferroni-corrected p = 0.006). Further, plasma IL-4 concentrations were significantly lower in SLE patients than in healthy controls (1.59 + 3.53 versus 5.67 + 11.28 pg/ml, p = 0.042). These results indicated that IL4 and STAT6 genes might be involved in the etiology of SLE and potentially increased SLE risk through their interaction effect in Chinese patients.

Abstract
OBJECTIVES The polarization of Th1/Th2 towards Th1 contributes to the pathogenesis of idiopathic thrombocytopenic purpura (ITP). Cytokines may play crucial roles in the pathogenesis of ITP. The purpose of this study was to investigate whether the interferon (IFN)-gamma +874(A/T) and interleukin-4 (IL-4) variable number of tandem repeats (VNTR) in intron3 polymorphisms may be responsible in part for genetic susceptibility to ITP. METHODS Genotyping of IFN-gamma +874A/T and IL-4 intron3 VNTR was performed in 196 patients with ITP and 128 healthy individuals by polymerase chain reaction sequence-specific primers and direct PCR respectively. RESULTS There was no association between IFN-gamma +874A/T and IL-4 intron3 VNTR polymorphism and ITP risk when all patients, as a group, were analyzed. When the patients were subdivided into two groups: childhood ITP and adult ITP, no statistical differences were found in the genotype and allele frequencies of IFN-gamma +874A/T and IL-4 intron3 VNTR between the two groups and the controls. Similar results were observed between acute childhood ITP, chronic childhood ITP, acute adult ITP or chronic adult ITP and the controls. CONCLUSION These polymorphisms were distributed similarly between the patients with ITP and the controls, demonstrating that these two candidate gene polymorphisms are not attributed to ITP susceptibility.

Abstract
Interleukin (IL)-18, an important mediator of innate and adaptive immunity, plays multiple roles in chronic inflammation, in autoimmune diseases, in a variety of cancers and in number of infectious diseases. IL-18 promoter polymorphisms have been also noted associated with various inflammatory diseases. We investigated the association of IL-18 promoter polymorphisms (-656T/G, -607A/C and -137C/G) with systemic lupus erythematosus (SLE) in Taiwan Chinese patients and controls. Six haplotypes (hts) were identified from the three promoter polymorphisms. The genotype distribution of the ht1 (GCC), ht2 (TAC), ht4 (GAC) and ht5 (TCC) were different in patients and controls (P<0.002). Moreover, the haplotype and genotype frequencies of ht1 were significantly increased in patients with discoid rash (P=0.045, odds ratio (OR): 2.01, 95% confidence interval (CI): 1.01-4.00; P=0.027, OR: 5.13, 95% CI: 1.41-18.68). In addition, the homozygous genotype ht1/ht1 was significant increased in patients with serositis (P=0.015, OR: 9.78, 95% CI: 1.55-61.73). These observations suggest that the three promoter polymorphisms contribute to the genetic background of SLE pathogenesis.

Abstract
Interleukin-4 (IL-4) and interleukin-4 receptor (IL-4R) modulate inflammation and are associated with the colorectal adenoma-carcinoma progression and the metastatic capacity. IL-4 also causes a dose-dependent reduction of proliferation in colorectal cancer cells. The aim of the study was to evaluate whether genetic variants within IL4 and IL4R could affect the individual risk to develop colorectal cancer. We genotyped all the polymorphisms coding for an aminoacidic change in IL4R and we used a haplotype-tagging SNP approach for IL4. We carried out a case-control association study by genotyping, with the 5' nuclease assay, two common SNPs within IL4 (-588C>T, Ex1-168G>A) and five SNPs within IL4R (I75V, C431R, S436L, S503P, Q576R) in 377 cases of colorectal cancer and 326 controls from Spain. No statistically significant association between the SNPs investigated and colorectal cancer risk was found, as main effects. When the sub-analyses were carried out, the homozygotes for IL4 -588C>T or for Ex1-168G>A showed an increased risk for colon cancer only, with the odds ratios of 4 (95% CI 0.97-16.6; P-interaction=0.016 and 4.66 (95% CI 1.16-18.77; P-interaction=0.023), respectively. Moreover, women showed a significant increased risk associated to the IL4 rare alleles and this was clearly greater than that in men (for Ex1-168G>A: OR=1.96; 95% CI=1.11-3.47; P-interaction=0.006). However, when sub-groups are analysed, the findings should be taken with caution for the weakening of the statistical power.

Abstract
Systemic lupus erythematosus (SLE) is a complex polygenic autoimmune disease characterized by the presence of anti-nuclear autoantibodies (ANAs) that are often detectable years prior to the onset of clinical disease. The disease is associated with a chronic activation of the immune system, with the most severe forms progressing to inflammatory damage that can impact multiple organ systems in afflicted individuals. Current therapeutic strategies poorly control disease manifestations and are generally immunosuppressive. Recent studies in human patient populations and animal models have associated elements of the innate immune system and abnormalities in the immature B lymphocyte receptor repertoires with disease initiation. A variety of cytokines, most notably type I interferons, play important roles in disease pathogenesis and effector mechanisms. The genetic basis for disease susceptibility is complex, and analyses in humans and mice have identified multiple susceptibility loci, several of which are located in genomic regions that are syntenic between humans and mice. The complexities of the genetic interactions that mediate lupus have been investigated in murine model systems by characterizing the progressive development of disease in strains expressing various combinations of susceptibility alleles. These analyses indicate that genetic epistasis dramatically impact disease development and support the feasibility of identifying molecular pathways that can suppress disease progression without completely impairing normal immune function.

Abstract
Because fibromyalgia (FM) is often comorbid with anxiety, and monoamine oxidase A (MAOA) was reported to be associated with anxiety, we determine if there is MAOA gene polymorphism associated with FM patients. Moreover, interleukin 4 (IL-4) was found to be an important cytokine participating in the immunologic pathway of T-helper 2 (Th-2) cells, in this study, we search if the genetic polymorphism of IL-4 intron3 could be demonstrated in FM patients. The genotype of sixty-two FM patients was compared with that of control subjects. The polymorphism of IL-4 intron3 variable number of tandem repeats (VNTR) was demonstrated by performing the genomic polymerase chain reaction (PCR) and analyzing the length of PCR product. Furthermore, the MAOA 941 G to T polymorphism was also determined by PCR-RFLP (restriction fragment length polymorphism) analysis. The MAOA 941 position genotype polymorphism between FM and control subjects was found neither statistically different in male (p=0.60) or female (p=0.52), nor total allelic frequency (p=0.52). Similarly, the difference of IL-4 intron3 polymorphism between FM and control was neither existing in genotype (p=0.06), nor allele frequency (p=0.07). The result suggests either the genetic linkage between FM and anxiety or that between FM and immunologic diseases are weak. Accordingly, the MAOA 941 position and IL-4 intron3 polymorphisms are not susceptible markers to predict FM.

Abstract
Trichloroethylene (TCE)-induced severe generalized dermatitis (SGD) is considered to be a contact allergic disease and is dependent on a cell-mediated immune response. Little is known about its pathogenesis. Several lines of evidence suggest that tumour necrosis factor (TNF) and interleukin 4 (IL-4) are involved in the immunological and inflammatory reactions. To investigate the relation between polymorphisms of TNF and the IL-4 gene and the risk of TCE-induced SGD, a case-control study was conducted consisting of 111 patients diagnosed with SGD and 152 TCE-exposed workers without SGD. Polymerase chain reaction-restriction fragment length polymorphism was used to detect the polymorphisms of TNF-alpha (G-238A, G-308A), TNF-beta (intron 1) and IL-4 (C-590T). Logistic regression was applied to calculate the odds ratios (OR) and 95% confidence intervals. The results reveal that the frequency of TNF alpha-308 wild allele in cases was significantly higher than that in control subjects (p=0.049). Individuals with a heterozygous genotype of TNF alpha-308 were associated with the decreased risk of TCE-induced SGD relative to the homozygous genotype (OR=0.398, 95% CI=0.164-0.967). No significant differences in the allele and genotype frequencies could be demonstrated at any other polymorphic loci among both groups. The finding of a possible contribution of a TNF-alpha genetic polymorphism is a primary result because the pathogenesis of TCE-induced SGD is complex and likely to involve the interaction of a number of genes. A further study should be conducted to illustrate the influence of a link between certain relevant alleles in the assessment of genetic susceptibility

Abstract
Interleukin 4 (IL-4) stimulates and amplifies the inflammatory response, stimulates collagen synthesis in fibroblasts, promotes the progression to fibrosis and has been shown to inhibit the production of several inflammatory cytokines in the development of bronchopulmonary dysplasia (BPD) and airway hyperreactivity. We aimed to investigate whether IL-4 polymorphisms in ventilated preterm infants were associated with BPD. BPD was defined as infants who remained dependent on active respiratory support or oxygen supplementation at 36 weeks postconceptional age. A case-control study of 224 preterm infants (<30 weeks) who had respiratory distress syndrome and needed intermittent mandatory ventilation (IMV) were undertaken between January 1999 and December 2003. The typing of each genetic polymorphism was performed by polymerase-chain-reaction-based restriction analysis. Genotype distribution and allelic frequencies were compared between ventilated preterm infants who developed BPD and those who did not and the duration of IMV. The demography of these ventilated BPD and non-BPD preterm infants was not different. We observed no significant differences in genotype distribution or allelic frequency of the IL-4 intron 3 or IL-4 promoter polymorphisms between ventilated preterm infants who developed BPD and who did not. There was no significant association of the genotype or allelic frequency of IL-4 polymorphism with duration of IMV. We conclude that neither IL-4 intron 3 nor the 590 promoter polymorphism is a useful marker for predicting the susceptibility to BPD in ventilated Taiwanese preterm infants.

Abstract
Immune thrombocytopenic purpura (ITP) is an immune-mediated disorder. We investigated the polymorphisms of interleukin (IL)-4 intron 3, IL-6 (-572 G/C), and IL-10 (-627 C/A) in 50 children with acute ITP, 30 children with chronic TIP, and 100 healthy individuals. There were significant differences in the RP1/RP2 genotype proportion (P = 0.04) and the RP2 allelic frequency (P = 0.03) of IL-4 intron 3 and the A/C genotype proportion (P = 0.01) of IL-10 (-627) between children with chronic ITP and controls. This finding suggests that the IL-4 intron 3 and IL-10 (-627) polymorphisms contribute to the susceptibility of developing childhood chronic ITP.

Abstract
OBJECTIVES To determine the circulating levels of Th1 and Th2 cytokines in patients with systemic lupus erythematosus (SLE) and to elucidate their association with disease activity and autoimmune response. METHODS We included 52 patients and 25 healthy controls. Serum levels of tumor necrosis factor (TNF) alpha, interferon (IFN) gamma, interleukin (IL)-12p70, IL-10, and IL-4, as well as anti-DNA, -Ro, -La, -RNP, and -Sm antibodies were determined by enzyme-linked immunosorbent assay. Disease activity was recorded according to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and classified as very active (SLEDAI > or = 13), moderately active (SLEDAI: 3-12), or inactive (SLEDAI < or = 2). RESULTS The mean age of the patients was 34.2 +/- 12.6 years, and the mean duration of disease was 4.9 +/- 7.6 years. Twelve patients (23%), 20 patients (34.5%), and 20 patients (34.5%) had highly, moderately, and inactive SLE, respectively. Levels of IFN-gamma, TNF-alpha, and IL-12 were significantly higher in patients than in healthy controls (P <.03), as well as the IL-12/IL-10, IL-12/IL-4, IFN/IL-10, IFN/IL-4, TNF/IL-10, and TNF/IL-4 ratios (P <.01), suggesting a major participation of Th1 over Th2 cytokines. Nevertheless, a direct correlation between Th1 (IFN-gamma and TNF-alpha) and Th2 (IL-4 and IL-10) cytokines was observed in patients (r >.5, P <.01), indicating a mutual Th1-Th2 participation. TNF-alpha levels and the TNF/IL-10 ratio were higher in patients with inactive disease compared with patients with very active disease and controls (P <.04). IL-12 levels and IL-12/IL-4, as well as IL-12/IL-10, ratios were higher in patients with very active disease than in those with inactive SLE and controls (P <.01). IL-10 levels were associated with anti-DNA, anti-Ro, and anti-La response (P <.01). CONCLUSION Our results suggest that TNF-alpha could be a protective factor in SLE patients, whereas IL-12p70 participates in disease activity and IL-10 influences the autoimmune response (autoantibody production).

Abstract
Allergic asthma is caused by genetic and environmental factors that interact to determine disease susceptibility and severity. Several lines of evidence suggest that the interleukin (IL-4 gene and the IL-4-receptor alpha (IL-4Ralpha) gene are involved in the development of atopic diseases. We sought to determine whether two polymorphism sites in IL-4 and IL-4Ralpha chain were associated with allergic asthma in a Chinese population. We obtained DNA and clinical data from allergic asthma patients, which were compared with those of a group of healthy control subjects. The subjects were genotyped for the IL-4 C-590T promoter polymorphism and the IL-4R alpha chain Q576R by polymerase chain reaction-restriction fragment length polymorphism. The results showed that the IL-4 C-590T was not associated with allergic asthma in a Chinese population. However, the IL-4R alpha chain 576R/R was significantly increased in allergic asthma patients compared with control subjects (chi2 = 21.16; p < 0.01), and also total plasma immunoglobulin E (IgE) level was increased in allergic asthma patients. These data suggest that the IL-4R alpha chain 576R/R genotypes confer genetic susceptibility to allergic asthma in Chinese.

Abstract
Recent advances in cytokine biology have led to novel approaches to the treatment of inflammatory diseases. In this article, we review recent data regarding the role of functional polymorphisms in the genes encoding the prototypic Th1 cytokine interferon gamma and Th2 cytokine interleukin 4 in multifactorial disorders. We have compared genetic data across a heterogeneous assortment of such conditions using a 'haplotype tagging' approach, and demonstrate that cytokine gene association studies are instrumental in the identification of specific disease states or clinical manifestations that are probably caused by genetically determined aberrant cytokine expression. Some of these new findings suggest cytokine effects that go beyond a classical Th1-Th2 dichotomy. Thus, we propose that this information could provide novel targets for immunotherapy and, in particular, might facilitate the identification of clinical subgroups of patients who, by virtue of their genetic constitution at these cytokine gene loci, are more likely to benefit from cytokine agonist or antagonist therapy.
