Immunoglobulin G binding activity of Brucella abortus.

Abstract:

:A Brucella abortus protein with a molecular weight of 50 kDa has been shown to bind bovine immunoglobulin G from healthy, brucellosis-free animals. The Brucella immunoglobulin G binding molecule appears to be a protein, since it is susceptible to proteolysis. The protein is presumed to be located on the cell surface, since intact cells precipitate bovine immunoglobulin G. Examination of other species of Brucella shows that all Brucella species and strains tested express the protein. B. abortus cells also bound immunoglobulin G from other animal species. These included cat, chicken, dog, guinea pig, horse, human, mouse, rat, sheep, swine, and turkey but not immunoglobulin G from goat or rabbit.

  • CD4 regulation in human lymphoid non-T-cells: a role for the silencer element.

    abstract::In humans, the CD4 molecule is expressed on a subset of T-cells and at various levels on myeloid and lymphoid cells. The mechanisms regulating human CD4 gene expression are yet poorly understood. We speculated that the CD4 silencer, which operates in CD8+ T-cells to repress CD4 expression, could be responsible for CD4...
