Borrelia burgdorferi-infected mice develop acute arthritis that undergoes Ab-mediated resolution. To further investigate the role of B. burgdorferi- specific Abs in Lyme borreliosis, CD40 ligand-deficient (CD40L-deficient) mice were infected with B. burgdorferi. The development and regression of arthritis were similar in CD40L-deficient and control mice. Although CD40L- deficient mice have defects in Ig class switching, infected CD40L-deficient mice developed B. burgdorferi-specific IgG2b Abs. Moreover, the transfer of serum from B. burgdorferi-infected CD40L-deficient animals prevented infection in severe combined immunodeficient mice. These data show that B. burgdorferi-infected CD40L-deficient mice are capable of producing Abs that are protective, despite the inability of these mice to mediate T-dependent immune responses.
