BACKGROUND
Hepatitis B virus infection remains an important global health concern despite the availability of safe and effective prophylactic vaccines. Limitations to these vaccines include… (More)

Bacterial biofilm formation is a complex developmental process involving cellular differentiation and the formation of intricate 3D structures. Here we demonstrate that exposure to ferric chloride… (More)
Amyloid is a distinct β-sheet-rich fold that many proteins can acquire. Frequently associated with neurodegenerative diseases in humans, including Alzheimer's, Parkinson's and Huntington's diseases,… (More)
T17 (T-helper-17) cytokine responses have been recently recognized as an important component for the protective immunity produced by vaccination. However, the mechanism by which immune adjuvants… (More)
Many bacteria can assemble functional amyloid fibers on their cell surface. The majority of bacterial amyloids contribute to biofilm or other community behaviors where cells interact with a surface… (More)
While the nasal mucosa is a potentially useful site for human immunization, toxin-based nasal adjuvants are generally unsafe and less effective in humans. Safe mucosal adjuvants that activate… (More)
Burkholderia cepacia complex (Bcc) are opportunistic bacteria associated with life-threatening illness in persons with cystic fibrosis. Once Bcc colonization is established, these… (More)
To elucidate mechanisms involved in M cell uptake and transcytosis of Vibrio cholerae, we used an in vitro model of human M-like cells in a Caco-2 monolayer. Interspersed among the epithelial… (More)
Nasal administration of an oil-in-water nanoemulsion (NE) adjuvant W805EC produces potent systemic and mucosal, Th-1- and Th-17-balanced cellular responses. However, its molecular mechanism of action… (More)
Curli amyloid fibers are the major protein component of the extracellular matrix produced by Enterobacteriaceae during biofilm formation. Curli are required for proper biofilm development and… (More)
