Mn²⁺-Enriched mRNA Nanoparticles for Better Vaccines
2026-08-31
The reference study introduces a manganese-ion strategy that condenses mRNA into a dense core before lipid coating, addressing the limited RNA payload of conventional lipid nanoparticles. The resulting L@Mn-mRNA system nearly doubles mRNA loading, improves cellular uptake, and strengthens vaccine responses while potentially reducing lipid-associated and anti-PEG immune liabilities.

TRPV1+ Nerves Suppress Inflammation via Reflex
2026-08-29
Song et al. identify a somato-autonomic reflex in which stimulation of TRPV1+ peripheral afferents at the nape engages brainstem, adrenal, vagal, and splenic pathways to reduce systemic inflammatory signaling. The study combines pharmacological stimulation, genetic validation, endocrine measurements, and splenic RNA sequencing to connect a defined sensory input with immune regulation.

Ibrexafungerp Against Resistant Candida
2026-08-27
The reference study evaluates ibrexafungerp, also called MK 3118, against 192 clinically derived Candida isolates with phenotypic or genotypic echinocandin resistance. By combining EUCAST susceptibility testing, FKS hotspot sequencing, and wild-type upper limits, it shows that activity is often retained but varies substantially by species and mutation location.
