DbpA, but not OspA, is expressed by Borrelia burgdorferi during spirochetemia and is a target for protective antibodies.
DbpA is a target for antibodies that protect mice against infection by cultured Borrelia burgdorferi. Infected mice exhibit early and sustained humoral responses to DbpA and DbpB, suggesting that these proteins are expressed in vivo. Many antigens expressed in mammals by B. burgdorferi are repressed in vitro at lower growth temperatures, and we have now extended these observations to include Db...
متن کاملRoles of OspA, OspB, and flagellin in protective immunity to Lyme borreliosis in laboratory mice.
Vaccination with recombinant outer surface protein A (OspA) has been shown to protect mice from infection with Borrelia burgdorferi, the Lyme disease agent. To determine whether antibodies to B. burgdorferi proteins other than OspA are involved in protective immunity, antibodies to OspA were removed from protective anti-B. burgdorferi serum; the residual serum was still protective. Absorption o...
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 کاملClonal polymorphisms of outer membrane protein OspB of Borrelia burgdorferi.
The outer membrane protein OspB of Borrelia burgdorferi, the Lyme borreliosis agent, differs in relative molecular weight (Mr) among strains. To determine whether antigenic variation occurs in B. burgdorferi, a cell population of the human isolate HB19 was cloned first by being diluted in broth and then by being plated on agar medium. Several clones were obtained and characterized by polyacryla...
متن کاملProtective niche for Borrelia burgdorferi to evade humoral immunity.
The Lyme disease spirochete, Borrelia burgdorferi, is an extracellular microbe that causes persistent infection despite the development of strong immune responses against the bacterium. B. burgdorferi expresses several ligand-binding lipoproteins, including the decorin-binding proteins (Dbps) A and B, which may mediate attachment to decorin, a major component of the host extracellular matrix du...
