A newly discovered cholesteryl galactoside from Borrelia burgdorferi

Ben-Menachem, Gil, Kubler-Kielb, Joanna, Coxon, Bruce, Yergey, Alfred, Schneerson, Rachel

Two major glycolipids, which comprise ≈36% of the total lipid mass from Borrelia burgdorferi, the etiological agent of Lyme disease, were investigated. We determined the fatty acid type, sugar...

Poly(γ-d-glutamic acid) protein conjugates induce IgG antibodies in mice to the capsule of Bacillus anthracis: A potential addition to the anthrax vaccine

Schneerson, Rachel, Kubler-Kielb, Joanna, Liu, Teh-Yung, Dai, Zhong-Dong, Leppla, Stephen H., Yergey, Alfred, ...

Both the protective antigen (PA) and the poly(γ-d-glutamic acid) capsule (γdPGA) are essential for the virulence of Bacillus anthracis. A critical level of vaccine-induced IgG anti-PA confers...

Chemical Structure, Conjugation, and Cross-Reactivity of Bacillus pumilus Sh18 Cell Wall Polysaccharide

Kubler-Kielb, Joanna, Coxon, Bruce, Schneerson, Rachel

Bacillus pumilus strain Sh18 cell wall polysaccharide (CWP), cross-reactive with the capsular polysaccharide of Haemophilus influenzae type b, was purified and its chemical structure was elucidated...

Additional Conjugation Methods and Immunogenicity of Bacillus anthracis Poly-γ-d-Glutamic Acid-Protein Conjugates

Kubler-Kielb, Joanna, Liu, Teh-Yung, Mocca, Christopher, Majadly, Fathy, Robbins, John B., Schneerson, Rachel

The capsule of Bacillus anthracis, composed of poly-γ-d-glutamic acid (γDPGA), is an essential virulence factor of B. anthracis. The capsule inhibits innate host defense through its antiphagocytic...

Long-lasting and transmission-blocking activity of antibodies to Plasmodium falciparum elicited in mice by protein conjugates of Pfs25

Kubler-Kielb, Joanna, Majadly, Fathy, Wu, Yimin, Narum, David L., Guo, Chunyan, Miller, Louis H., ...

Malaria is a leading cause of morbidity and mortality, estimated to cause >1 million childhood deaths annually. Plasmodium falciparum causes the most severe form of the disease. There is as yet no...

Effect of the nonreducing end of Shigella dysenteriae type 1 O-specific oligosaccharides on their immunogenicity as conjugates in mice

Pozsgay, Vince, Kubler-Kielb, Joanna, Schneerson, Rachel, Robbins, John B.

Endemic and epidemic shigellosis, an acute invasive disease of the lower intestines, afflicts millions of people worldwide with an estimated one million fatalities per annum at a low infectious dose....

Saccharides cross-reactive with Bacillus anthracis spore glycoprotein as an anthrax vaccine component

Kubler-Kielb, Joanna, Vinogradov, Evgeny, Hu, Haijing, Leppla, Stephen H., Robbins, John B., Schneerson, Rachel

Bacillus anthracis is a spore-forming bacterium that causes anthrax in humans and in other mammals. The glycoprotein BclA (Bacillus collagen-like protein of anthracis) is a major constituent of the...

Synthesis, characterization, and immunogenicity in mice of Shigella sonnei O-specific oligosaccharide-core-protein conjugates

Robbins, John B., Kubler-Kielb, Joanna, Vinogradov, Evguenii, Mocca, Christopher, Pozsgay, Vince, Shiloach, Joseph, ...

Shigellosis, an enteric disease, is on the World Health Organization's priority prevention list. In one study, the Shigella sonnei O-specific polysaccharide (O-SP)-protein conjugate showed 72%...
