Abstract

Neisseria meningitidis serogroup W-135 appears to be a fairly common cause of infection associated with properdin deficiency or dysfunction, and anticapsular antibodies might be protective in these patients. For this reason, bactericidal and opsonophagocytic activities for serogroup W-135 were investigated before and four weeks after vaccination of two properdin-deficient adults with tetravalent meningococcal vaccine. In addition, the response of IgM, IgG and IgA class antibodies to the serogroups A, C, Y and W-135 was determined by ELISA. There was no evidence of poor antibody responses in the properdin-deficient persons. Vaccination promoted classical pathway-mediated killing in serum and opsonization of serogroup W-135 to the same extent as that seen in vaccinated controls. The increase of alternative pathway-mediated killing in the properdin-deficient sera was moderate, but vaccination clearly enhanced alternative pathway-mediated opsonophagocytosis in the sera. It was also shown that vaccination markedly reduced the requirement for properdin in alternative pathway-mediated killing of the meningococci.

Alternative Complement Pathway

The Alternative Complement Pathway is part of the innate immune system, and activation generates membrane attack complexes that kill pathogenic cells. Discover the latest research on the Alternative Complement Pathway.

Antibody-Dependent Cell Cytotoxicity

Antibody-dependent cellular toxicity refers to the lysis of a target cell by a non-sensitized effector cell of the immune system as a result of antibodies binding to the target cell membrane and engaging the Fc receptors on the immune effector cells.

Acute disseminated encephalomyelitis (ADEM) is a rare inflammatory demyelinating disease of the central nervous system. Discover the latest research on acute disseminated encephalomyelitis here.

Antibodies: Complement Activation

The complement system can be activated by antigen-associated antibody. In the classical pathway of complement activation, C1q, C4b, and C3b are all able to bind to the Fc portion of IgG or IgM. Find the latest research on antibodies and complement activation here.
