Role of glutathione metabolism in host defense against Borrelia burgdorferi infection Immunology and Inflammation

In this study, we investigated how infection with the Lyme disease-causing bacterium Borrelia burgdorferi (Bb) affects host metabolic pathways and how these metabolic pathways may impact host defense. First, metabolome analysis was performed on human...

Ticks and mosquitoes don’t care about COVID-19 safety protocols. They don’t care that people are trying to squeeze out the last moments of this restrictive summer by getting outdoors, hiking, or just sitting on their decks at night and feeling something that’s close to normal. COVID-19 has commanded our attention and caused people to adapt their behaviors to prevent one major health concern, but it doesn’t mean others have been eliminated. “Masks and social distancing will do nothing to protect you from what ticks and mosquitoes potentially carry,” says Dr. Todd Ellerin, director of infe...

AbstractBorreliosis (Lyme disease) is a spirochetal disease caused by the species complex ofBorrelia burgdorferi transmitted byIxodes spp. ticks. Recorded to be the most common tick ‐borne disease in the world, the last two decades have seen an increase in disease incidence and distribution, exceeding 360 000 cases in Europe alone. If untreated, infection may cause skin symptoms, arthritis, neurological or cardiac complications. Borrelia spirochetes have developed strategies to evade the mammalian host immune system. These include the complement system, which is an important first‐line defence mechanism against invadin...

We report the results of gene expression profiling via RNA-sequencing of primary human choroid plexus epithelial cells in vitro that were infected with Borrelia burgdorferi, the causative agent of Lyme disease. Epithelial cells were cultured with B. burgdorferi for 48 hours prior to RNA isolation. Following high-throughput sequencing via Illumina HiSeq 4000, a total of 258 differentially expressed genes were identified. Subsequent data analysis indicates an inflammatory and immune response generated by the epithelial cells following infection, marked by chemotactic cytokines and interferon stimulated genes. Several genes a...

We examined the effect of a positive serostatus at baseline for selected pathogens associated with chronic infections (Helicobacter pylori,Borrelia burgdorferi sensulato,Toxoplasma gondii, cytomegalovirus, Epstein-Barr virus, herpes simplex virus 1/2, and human herpesvirus 6) on all-cause mortality with multivariable parametric survival models. We found a reduced survival time in individuals with a positive serostatus forHelicobacter pylori (accelerated failure time (AFT) − 15.92, 95% CI − 29.96; − 1.88), cytomegalovirus (AFT − 22.81, 95% CI − 36.41; −&...

Compared to the standard two-tiered testing (STTT) algorithm for Lyme disease serology using an enzyme immunoassay (EIA) followed by Western blotting, data from the United States suggest that a modified two-tiered testing (MTTT) algorithm employing two EIAs has improved sensitivity to detect early localized Borrelia burgdorferi infections without compromising specificity. From 2011 to 2014, in the Canadian province of Nova Scotia, where Lyme disease is hyperendemic, sera submitted for Lyme disease testing were subjected to a whole-cell EIA, followed by C6 EIA and subsequently IgM and/or IgG immunoblots on sera with EIA-pos...
