“We searched pathogenic bacteria for a self-assembled protein nanoarchitecture that could serve as a new antigen-delivery vehicle,” says Sangyong Jon of the Korea Advanced Institute of Science ...

Bacteria are ubiquitous microscopic organisms capable of rapid growth. While beneficial strains like lactic acid bacteria ...

Bacteria have evolved antibody-binding proteins, such as staphylococcal protein A and streptococcal protein G, to evade host immunity. A study now identifies a new antibody-binding protein in ...

More information: Bacterial ClpB heat-shock protein, an antigen-mimetic of the anorexigenic peptide α-MSH, at the origin of eating disorders, Translational Psychiatry, October 2014 DOI: 10.1038 ...

New research from the University of Cincinnati demonstrates how specially engineered bacteria taken orally can operate as a delivery system for antiviral therapies and vaccines. The research, led ...

Most engineered bacteria keep their therapeutic cargo inside the cell, but vaccines work best when antigens are presented to the immune system. The UC team therefore displayed viral proteins on the ...

This is why a single dose of a bacterial vaccine can contain many different antigens. For instance, the “20” in Pfizer’s PREVNAR 20 pediatric pneumonia vaccine refers to the 20 unique ...

Upon conducting further analyses, the team found that treating dendritic cells with valeric acid led to an increase in the uptake of soluble proteins, insoluble beads, and Staphylococcus aureus ...

Antigen vs antibody: the basics. An antigen is any substance that prompts your body to trigger an immune response against it. Antigens include allergens, bacteria and viruses. Antibodies are Y-shaped ...

Omniose, a company developing polysaccharide conjugate vaccines against serious bacterial threats, has been awarded a $3.6 million grant for the devel ...
