Project description:Whole-genome single-base resolution methylcytosine map reveals profound changes that occur after Lsh deletion during embryonic development in primary WT and Lsh-/- MEFs. Lsh deletion leads to widespread decreases of CG methylation level at uniquely mapped genomic regions compared to wild type, including TSSs at protein-coding genes, and non-coding RNA genes. MethylC-Seq from Mus musculus primary MEFs.

Project description:This study aims to investigate the immunemodulatory effects of excretory-secretory products (ESPs) from the parasite Taenia solium on human macrophages to understand immunopathogenesis of neurocysticercosis (NCC). NCC is an infection of the central nervous system caused by the larvae of T. solium and is a major contributor to acquired epilepsy. Although ESPs from parasites are known to possess immune-modulating properties, the specific mechanisms of their action in NCC remains unclear. Therefore, this expression study seeks to shed light on the exact mechanism by which T. solium ESPs exert their immune-suppressive effects on human macrophages. Understanding this mechanism can provide valuable insights into the pathogenesis of NCC and potentially contribute to the development of novel therapeutic strategies for managing the disease. The study employed miRNA microarray technology to investigate the post-translational effects of excretory-secretory products (ESPs) from Taenia solium on human macrophage function. microRNAs, are small non-coding RNA molecules that play a crucial role in post-transcriptional gene regulation. The aim of study is to identify specific miRNAs that might be responsible for modulating macrophage function. Altered expression of miRNAs can influence the translation and stability of target mRNA molecules, subsequently affecting the production of proteins and the overall function of macrophages, thus affecting immune homeostasis in infection. Understanding the miRNA-mediated regulatory mechanisms involved in the immune response to T. solium infection can contribute to a better understanding of the pathogenesis of neurocysticercosis and potentially uncover novel therapeutic targets for managing the disease.

Project description:We have designed species-specific oligonucleotides which permit the differential detection of two species of cestodes, Taenia saginata and Taenia solium. The oligonucleotides contain sequences established for two previously reported, noncoding DNA fragments cloned from a genomic library of T. saginata. The first, which is T. saginata specific (fragment HDP1), is a repetitive sequence with a 53-bp monomeric unit repeated 24 times in direct tandem along the 1, 272-bp fragment. From this sequence the two oligonucleotides that were selected (oligonucleotides PTs4F1 and PTs4R1) specifically amplified genomic DNA (gDNA) from T. saginata but not T. solium or other related cestodes and had a sensitivity down to 10 pg of T. saginata gDNA. The second DNA fragment (fragment HDP2; 3,954 bp) hybridized to both T. saginata and T. solium DNAs and was not a repetitive sequence. Three oligonucleotides (oligonucleotides PTs7S35F1, PTs7S35F2, and PTs7S35R1) designed from the sequence of HDP2 allowed the differential amplification of gDNAs from T. saginata, T. solium, and Echinococcus granulosus in a multiplex PCR, which exhibits a sensitivity of 10 pg.

Project description:Neurocysticercosis (NCC) is a parasitic infection of the central nervous system caused by Taenia solium larval cysts. Its epidemiology in cysticercosis-nonendemic regions is poorly understood, and the role of public health institutions is unclear. To determine the incidence of NCC and to pilot screening of household contacts for tapeworms, we conducted population-based active surveillance in Oregon. We screened for T. solium infection by examining hospital billing codes and medical charts for NCC diagnosed during January 1, 2006-December 31, 2009 and collecting fecal and blood samples from household contacts of recent case-patients. We identified 87 case-patients, for an annual incidence of 0.5 cases per 100,000 general population and 5.8 cases per 100,000 Hispanics. In 22 households, we confirmed 2 additional NCC case-patients but no current adult intestinal tapeworm infections. NCC is of clinical and public health concern in Oregon, particularly among Hispanics. Public health intervention should focus on family members because household investigations can identify additional case-patients.
