TLDR
IL-13 −1055T may show resistance to severe malaria through the alteration of IL-13 production as well as other single-nucleotide polymorphisms in the promoters of IL, IL, and IL-4 genes on the 5q31–33.
Abstract
We examined a possible association of single-nucleotide polymorphisms (SNPs) in the promoters of IL-3, IL-4, and IL-13 genes on the 5q31-33, IL-3 -16T>C, IL-4 -590T>C, and IL-13 -1055C>T, with severity of malaria in 361 adult malaria patients in Thailand. The IL-13 -1055T allele showed a significant association with protection from severe malaria (OR 0.51, 95% CI 0.32-0.80; P=0.0032 by the chi(2) test), while allele frequencies of IL-3 -16T>C and IL-4 -590T>C were not statistically different between mild and severe malaria patients. An IL-13 -1055C>T has been reported to alter the regulation of IL-13 production. Thus, IL-13 -1055T may show resistance to severe malaria through the alteration of IL-13 production.

Th2 Cell-Selective Enhancement of Human IL13 Transcription by IL13-1112C>T, a Polymorphism Associated with Allergic Inflammation

TL;DR: The findings suggest the nuclear milieu dictates the functional outcome of genetic variation in primary human and murine CD4+ Th2 lymphocytes and that increased expression of IL13-1112T in vivo may underlie its association with susceptibility to allergic inflammation.

Insights into the immunopathogenesis of malaria using mouse models.

TL;DR: This review looks in detail at the processes involved in endothelial cell damage leading to syndromes such as cerebral malaria, as well as generalised systemic manifestations such as anaemia, cachexia and problems with thermoregulation of the body.

Proinflammatory and regulatory cytokines and chemokines in infants with uncomplicated and severe Plasmodium falciparum malaria

TL;DR: Elevated levels of proinflammatory and regulatory cytokines and chemokines were generated in infants during and after acute malaria tropica and may prove useful in evaluating either the progression or the regression of malarial disease.

Significant association of KIR2DL3-HLA-C1 combination with cerebral malaria and implications for co-evolution of KIR and HLA.

TL;DR: The results suggest that natural selection has reduced the frequency of the KIR2DL3-HLA-C1 combination in malaria high-endemic populations because of the propensity of interaction between KIR 2DL3 and C1 to favor development of cerebral malaria.

Distinct clinical and immunologic profiles in severe malarial anemia and cerebral malaria in Zambia.

TL;DR: Predictors of severe malarial anemia differed from those of cerebral malaria (thrombocytopenia, herbal medicine, and intravascular hemolysis), and improved preventive and therapeutic measures may need to consider these differences.

The Interaction of Selection and Linkage. I. General Considerations; Heterotic Models.

TL;DR: The results of these investigations were sufficient to show that even for relatively simple cases (two loci, simple symmetrical selective values) linkage might have profound effects on the course of natural selection and, pari passu, natural selection may have major effect on the distribution of coupling and repulsion linkage in a population.

Linkage analysis of IL4 and other chromosome 5q31.1 markers and total serum immunoglobulin E concentrations

TL;DR: Analysis of sib-pair analysis of 170 individuals from 11 Amish families revealed evidence for linkage of five markers in chromosome 5q31.1 with a gene controlling total serum immunoglobulin E (IgE) concentration, and a combination of segregation and maximum likelihood analyses provided further evidence.

Promoter polymorphisms in the chromosome 5 gene cluster in asthma and atopy

TL;DR: Asthma may develop secondary to the transcriptional dysregulation of T lymphocyte-derived cytokines, which contains the genes for interleukins 3, 4, 5,9, 13 and gruntilocyte macrophage-colony stimulating factor (GM-CSF).

Evidence for a locus regulating total serum ige levels mapping to chromosome-5

TL;DR: Evidence for linkage of the IgE phenotype to 5q was obtained by both sib-pair and lod score analysis with evidence for recessive inheritance of high IgE levels from segregation analysis, a major step in mapping genes important in the regulation of allergic responses and the pathogenesis of asthma.
