Bovine Respiratory Syncytial Virus Nanovaccine Induces Long-Lasting Humoral Immunity in Mice.

With limited therapies and vaccines available, human respiratory syncytial virus (HRSV) has a significant negative health impact on all age groups but particularly on infants, young children, and older adults. Bovine respiratory syncytial virus (BRSV) is pathogenically and antigenically similar to HRSV. Building upon previous studies using a BRSV nanovaccine coencapsulating multiple proteins, this work demonstrates the development and comparative evaluation of a coencapsulated nanovaccine to a cocktail nanovaccine formulation composed of polyanhydride nanoparticles encapsulating BRSV postfusion (F) glycoprotein and CpG ODN 1668 coadjuvant delivered simultaneously with nanoparticles encapsulating BRSV attachment glycoprotein (G) and CpG ODN 1668.

A single rare σ70 variant establishes a unique gene expression pattern in the E. coli pathobiont LF82.

LF82, an adherent-invasive Escherichia coli (AIEC) pathobiont, is associated with Crohn's disease, an inflammatory bowel disease of unknown etiology. Although AIEC phenotypes differ from those of 'commensal' or pathogenic E. coli, work has failed to identify genetic features accounting for these differences.

Next-generation nanovaccine induces durable immunity and protects against SARS-CoV-2.

While first generation SARS-CoV-2 vaccines were effective in slowing the spread and severity of disease during the COVID-19 pandemic, there is a need for vaccines capable of inducing durable and broad immunity against emerging variants of concern. Nanoparticle-based vaccines (i.e.

Inhibiting the cGAS-STING Pathway in Ulcerative Colitis with Programmable Micelles.

Ulcerative colitis is a chronic condition in which a dysregulated immune response contributes to the acute intestinal inflammation of the colon. Current clinical therapies often exhibit limited efficacy and undesirable side effects. Here, programmable nanomicelles were designed for colitis treatment and loaded with RU.

Study Transportation of Drugs within Newly Established Murine Colon Organoid Systems.

The development of 3D organoids of the small intestine is a tremendous breakthrough in drug development and biological research. However, the development of colonic organoids (i.e.
