Immunoglobulin-regulated expression of Borrelia burgdorferi outer surface protein A in vivo.
Borrelia burgdorferi, the agent of Lyme disease, down-regulates outer surface protein A (OspA), which is abundantly expressed in ticks, during infection of the mammalian host. In this study we examined the signals that may be responsible for maintaining the OspA-negative state of spirochetes during infection. Transcription of ospA mRNA was found in tissues of C3H-severe combined immunodeficient...
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...

متن کاملIdentification of Two Epitopes on the Outer Surface Protein A of the Lyme Disease Spirochete Borrelia burgdorferi
A murine IgM monoclonal antibody (MA-2C6) with κ-light chains directed against an antigenic determinant of outer surface protein A (OspA) of the Lyme disease spirochete, Borreliaburgdorferi, is produced. This antibody could bind specifically to OspA antigen of several isolates of B. burgdorferi, but not to the non-Lyme disease bacteria such as T. pallidum and B. hermsii. Antibody MA-2C6 was pur...
متن کاملInhibition of Borrelia burgdorferi-tick interactions in vivo by outer surface protein A antibody.
Borrelia burgdorferi outer surface protein (Osp) A is preferentially expressed by spirochetes in the Ixodes scapularis gut and facilitates pathogen-vector adherence in vitro. Here we examined B. burgdorferi-tick interactions in vivo by using Abs directed against OspA from each of the three major B. burgdorferi sensu lato genospecies: B. burgdorferi sensu stricto, Borrelia afzelii, and Borrelia ...
