Role Of Regulatory T Cells In The Development And Progression Of Lyme Disease In Balb/C Mice, Kaitlyn Nielsen
Role Of Regulatory T Cells In The Development And Progression Of Lyme Disease In Balb/C Mice, Kaitlyn Nielsen
Theses and Dissertations
Lyme disease, caused by Borrelia burgdorferi, is an increasingly important public health concern, with tens of thousands of new cases being diagnosed each year, even in previously non-endemic areas. It is known that symptoms of Lyme disease are caused by an inflammatory immune response initiated to aid in clearance of the pathogen. Left unchecked, these inflammatory responses can potentially increase tissue damage, leading to increased disease severity. Mechanisms responsible for the control of the inflammatory response to infection with B. burgdorferi are not entirely understood. Evidence exists that regulatory T (Treg) cells, a population of Foxp3-expressing CD4+ T cells known …
Regulatory Mechanisms In Borrelia Burgdorferi-Induced Arthritis, Emily Siebers Hansen
Regulatory Mechanisms In Borrelia Burgdorferi-Induced Arthritis, Emily Siebers Hansen
Theses and Dissertations
Lyme arthritis is a common symptom of Lyme borreliosis that involves inflammation of the synovial joints. Elucidating the immune events involved in Lyme arthritis is complicated by the fact that not all individuals infected with B. burgdorferi develop arthritis. Additionally, Lyme arthritis manifests in different severities between affected individuals. It is known that an inflammatory response is initiated by B. burgdorferi infection and that inflammatory T cells contribute to the development of arthritis. However, the anti-inflammatory mechanisms that regulate the pathogenic T cells’ response are not entirely understood. Here, the hypothesis that a dysregulated immune response results in an excessive …

Lyme arthritis is a debilitating joint disorder that arises from Lyme disease, which is a result of infection by the spirochete Borrelia burgdorferi. Antibiotics are the traditional treatment for Lyme disease, but chronic arthritis may persist in some patients despite antibiotic treatment. Therefore, other forms of treatment for Lyme arthritis are needed. Photobiomodulation (PBM) using red or near-infrared light, with wavelengths between 630 …
Role Of Interleukin-17 In The Adaptive Immune Response In Lyme Arthritis, Emily Siebers
Role Of Interleukin-17 In The Adaptive Immune Response In Lyme Arthritis, Emily Siebers
Theses and Dissertations
Lyme arthritis is a devastating symptom of Lyme borreliosis that causes severe inflammation of the synovial joints. Interleukin-17 (IL-17) plays a role in the pathogenesis of various arthritides, including, possibly, Lyme arthritis, by causing the expression of genes involved in the production of inflammatory cytokines by synoviocytes. However, the cellular sources of IL-17 in the context of Borrelia burgdorferi infection are unknown, as are the effects of these cells on the development of arthritis and stimulation of humoral immunity through the production of borreliacidal antibodies. Using multiple models of Lyme arthritis, the hypothesis that IL-17 produced by CD4+ cells contributes …
