Three-Dimensional Animated Videos Improve Caregiver Craniosynostosis Education.

Craniosynostosis management involves various surgical options early in a patient's life. Nevertheless, few three-dimensional (3D) tools exist to help caregivers comprehend craniosynostosis anatomy and surgical options. This study aims to assess the efficacy of 3D animated videos for enhancing craniosynostosis education in caregivers.

In Vivo Stimulation of Therapeutic Antigen-Specific T Cells in an Artificial Lymph Node Matrix.

T cells are critical mediators of antigen-specific immune responses and are common targets for immunotherapy. Biomaterial scaffolds have previously been used to stimulate antigen-presenting cells to elicit antigen-specific immune responses; however, structural and molecular features that directly stimulate and expand naïve, endogenous, tumor-specific T cells in vivo have not been defined. Here, an artificial lymph node (aLN) matrix is created, which consists of an extracellular matrix hydrogel conjugated with peptide-loaded-MHC complex (Signal 1), the co-stimulatory signal anti-CD28 (Signal 2), and a tethered IL-2 (Signal 3), that can bypass challenges faced by other approaches to activate T cells in situ such as vaccines.
