Abstract

Different genetic polymorphisms, particularly in the erythrocyte receptors and immune response-related genes, have been implicated in the development of malaria. With the first immune response to Plasmodium falciparum related to the activity of toll-like receptors (TLRs), we investigated the association of TLR polymorphisms with the clinical outcome of malaria among 662 children in Ibadan, Nigeria. The participants were genotyped for TLR1-rs5743611, TLR1-rs4833095, TLR4-rs4986791, TLR4-rs4986790, TLR6-rs5743810, TLR9-rs187084 and TLR9-rs5743809 using TaqMan real-time PCR probes and analyzed using the Sequenom iPLEX platform. Statistical analyses were performed using PLINK 2.0, Haploview 4.2 and SPSS® 20.0. Overall, the TLR genes were consistent with the Hardy-Weinberg equilibrium. The minor allelic frequency (MAF) of TRL1-rs4833095, TLR4-rs4986790, TLR4-rs4986791, TLR9-rs187084, TLR9-rs5743809 was 0.094, 0.089, 0.011, 0.288, and 0.044, respectively. The CT genotype of TLR1-rs4833095 was significantly associated with increased susceptibility to clinical malaria. Similarly, the GA and CT genotypes of TLR4-rs4986790 and TLR4-rs4986791, respectively, were linked to susceptibility to complicated malaria. TLR9-rs187084 CT was associated with the development of uncomplicated malaria, while TLR6-rs5743809 showed no significant association with malaria. Notably, TLR1-rs5743611 and TLR6-rs5743810 were monomorphic in the population. This study, pioneering in its exploration of TLR polymorphisms among Yorubas', underscores the need for expansive, large-scale investigations involving diverse TLR polymorphisms across multiple malaria-endemic populations.

期刊介绍: Pathogens and Global Health is a journal of infectious disease and public health that focuses on the translation of molecular, immunological, genomics and epidemiological knowledge into control measures for global health threat. The journal publishes original innovative research papers, reviews articles and interviews policy makers and opinion leaders on health subjects of international relevance. It provides a forum for scientific, ethical and political discussion of new innovative solutions for controlling and eradicating infectious diseases, with particular emphasis on those diseases affecting the poorest regions of the world.
