At present few vaccine candidates exists against potentially pandemic influenza virus infections. We provide compelling evidence that a targeted fusion protein based on the CTA1-DD adjuvant and containing tandem repeats of the matrix protein 2 (M2e) ectodomain epitope, CTA1-3M2e-DD, confers strong protective immunity against a potentially lethal challenge infection with influenza virus in mice. The...
Recent delayed matching studies have demonstrated that maintaining trial-unique stimuli in working memory modulates activity in temporal lobe structures. In contrast, most previous studies that focused on the role of the prefrontal cortex (PFC) used familiar stimuli. We combined fMRI with a delayed-match-to-sample (DMS) task in humans that allowed us to manipulate stimulus pre-exposure (trial-unique...
Semantic event sequencing is the ability to plan ahead and order meaningful events chronologically. To investigate the neural systems supporting this ability, an fMRI picture sequencing task was developed. Participants sequenced a series of four pictures presented in random order based on the temporal relationship among them. A control object discrimination task was designed to be comparable to the...
We recently developed a novel immunomodulating gene fusion protein, CTA1-DD, that combines the ADP-ribosylating ability of cholera toxin (CT) with a dimer of an Ig-binding fragment, D, of Staphylococcus aureus protein A. The CTA1-DD adjuvant was found to be non-toxic and greatly augmented T cell dependent and independent responses. Following injection it binds to both naı̈ve and memory B cells and...
