Multistep denaturation of Borrelia burgdorferi OspA, a protein containing a single-layer beta-sheet.
Outer surface protein A (OspA) from the Lyme disease spirochete, Borrelia burgdorferi, is a dumbbell-shaped protein in which two globular domains are connected by a three-stranded beta-sheet segment that is solvent-exposed on both faces. Previous studies showed that the whole protein, including the single-layer beta-sheet, is highly rigid. To elucidate the folding mechanism and the role of the ...
متن کاملSafety, immunogenicity, and efficacy of Borrelia burgdorferi outer surface protein A (OspA) vaccine: A meta-analysis.
INTRODUCTION Lyme borreliosis, caused by Borrelia burgdorferi sensu stricto in the United States and by several Borrelia species in Europe and Asia, has a great impact on the health of the global population. There are human vaccines available, such as the outer surface protein A (OspA) vaccine, but still more evidence is needed to verify its function. We investigated the safety, immunogenicity,...
متن کاملRelationship between immunity to Borrelia burgdorferi outer-surface protein A (OspA) and Lyme arthritis.
Antibiotic-refractory Lyme arthritis may result from Borrelia burgdorferi-induced autoimmunity in affected joints. Such patients usually have certain HLA-DRB1 molecules that bind an epitope of B. burgdorferi outer-surface protein A (OspA₁₆₃₋₁₇₅), and cellular and humoral immune responses to OspA are greater in patients with antibiotic-refractory arthritis than in those with antibiotic-responsiv...
متن کاملModulation of lymphocyte proliferative responses by a canine Lyme disease vaccine of recombinant outer surface protein A (OspA).
The modulation of human lymphocyte proliferative responses was demonstrated with a recombinant outer surface protein A (OspA) vaccine preparation for the prevention of Borrelia burgdorferi infection. After exposure to either the unaltered vaccine preparation or OspA prepared in saline, normal lymphocyte responses to the mitogens concanavalin A, phytohemagglutinin-M or pokeweed mitogen, or the a...
متن کاملExpression and Purification of Recombinant Outer Surface Protein D of Borrelia burgdorferi
To carry out the immunological experiments on the serum of Multiple Sclerosis (MS) patients, based on a correlation between Borrelia burgdorferi infection and contracting MS autoimmune disease the outer surface protein D (OspD) of the bacterium was expressed and purified. A clone containing the OspD gene in pET11a expression vector under the control of T7 promoter was transformed to the bacteri...
