Long double-stranded (ds)RNA, a potent stimulator of type I interferon and the innate immune response. In the present study, we demonstrated, for the first time, the efficacy of cationic polystyrene latex nanostructures (clNPs) as a dsRNA carrier, improving cellular delivery and robustly potentiating the immunostimulatory capacity of dsRNA in the ovarian cancer cell line SKOV3. The clNPs complexed with an in vitro transcribed dsRNA molecule, were bound by SKOV3 cells, and had increased cellular association compared to uncomplexed clNPs.

In this chapter, we present a comprehensive overview of four methodologies: electrophoretic mobility shift assay (EMSA), alamarBlue/CFDA-AM cell viability dyes, fluorescence microscopy, and antiviral assays, which collectively are tools to explore interactions between nucleic acids and nanoparticles, and their biological efficacy. These assays provide insights into binding potential, cytotoxicity, and antiviral efficacy of nucleic acid-based nanoparticle treatments furthering the development of effective antiviral therapeutics.

The American Board of Pediatrics launched the Roadmap Project to better support emotional health as part of routine care. We present pilot work in paediatric training programmes to test educational approaches and explore lessons learned.

Immunotherapy is a burgeoning area of cancer treatment, including for breast cancer; these are therapies that harness the power of the immune system to clear cancerous cells. Toll-like receptor 3 (TLR3) is an RNA receptor found in the endosome, and ligands that bind to TLR3 are currently being tested for their efficacy as breast cancer immunotherapeutics.
