Structural study of mucosal antibody reveals unexpected host-pathogen interactions
Secretory Immunoglobulin A (SIgA), the predominant human mucosal antibody, can bind to bacterial surface proteins and trigger an immune response to...

“Buckle up and hold on tight!” Study discovers how bacterial pathogens stick to surfaces better when they encounter fluid flow
Host tissues and medical devices are ideal surfaces for bacterial pathogens to colonize and infect. Fluid flow is thought to flush bacteria off these surfaces, but University of Illinois researchers have found that some bacteria can strengthen their adhesion to the surface when flow is applied.

New research challenges longstanding assumptions of evolutionary metal preferences
Thomas Kehl-Fie, a professor of microbiology in the School of Molecular & Cellular Biology, and collaborator Kevin Waldron, a professor at the Institute of Biochemistry & Biophysics in Warsaw, Poland, have found that have found that in response to the immune system restricting metal...

Context matters: Whitaker combines her passions for microbiology and education to better understand our world
Microbes, human beings, and the many systems we inhabit, from farms to factories and hospitals to high schools, are all connected. Working in natural environments, research labs, and local communities, Rachel Whitaker has been...

Scientists discover a small immune system that packs a big punch
A recent study by a team of researchers at the University of Illinois Urbana-Champaign has discovered a unique immune system in bacteria composed of a single enzyme that destroys a broad range of bacterial viruses (known as phages). Their findings were published in Cell Host & Microbe.

Machine-learning model can distinguish antibody targets
A new study from the School of Molecular & Cellular Biology shows that it is possible to use the genetic sequences of a person’s antibodies to predict what pathogens those antibodies will target. Reported in the journal Immunity, the new approach successfully differentiates between antibodies...

Researchers characterize the function of PaeA, a protein involved in Salmonella virulence
The regulation of polyamines is essential for the physiological function of organisms. Simplistically, polyamines are organic cations that interact with RNA, including ribosomes and translational machinery. Both the lack of and an excess of polyamines confer lethal phenotypes, though the molecular...

Researchers examine the biological role of epigenetic regulator Brd4 in inflammasome activation
Inflammasomes play a critical role in the innate cellular immune response to pathogen infection. The inflammasome, a cytosolic multiprotein complex, recognizes substrates produced during infection or tissue damage, and triggers an inflammatory response by releasing the proinflammatory cytokine IL-...
