The 4Q Principle for Stable mRNA Delivery
2026-09-21
Shi and colleagues proposed a 4Q framework that separates mRNA delivery into vector stability, diffusion, cellular internalization, and intracellular release. Their PBD polycation uses catechol interactions, disulfide reduction, and lipid shielding to improve room-temperature stability while preserving delivery performance.

Fast-Dissociating Antibodies for Single-Molecule Imaging
2026-09-19
Miyoshi et al. developed a semi-automated single-molecule TIRF assay to identify specific monoclonal antibodies with rapid antigen dissociation directly from hybridoma cultures. The resulting Fab probes supported multiplex super-resolution imaging and revealed rapid espin turnover within stable F-actin cores of sensory hair-cell stereocilia.

KCNE4-Dependent Modulation of Kv1.3 Pharmacology
2026-09-15
The reference study shows that the leukocyte auxiliary subunit KCNE4 changes Kv1.3 blocker behavior without measurably changing blocker affinity. Its stoichiometry-dependent slowing of intracellular Psora-4 inhibition highlights why channel composition and kinetic readouts matter when interpreting Kv1.3 pharmacology in immune-cell research.

How Kinase Inhibitors Accelerate p38α Dephosphorylation
2026-09-14
The reference preprint shows that selected kinase inhibitors can do more than block p38α catalytic activity: they can also expose the activation-loop phosphothreonine to WIP1, accelerating dephosphorylation. Structural and biochemical results establish a dual-action mechanism that could guide more selective kinase-inhibitor design, while remaining preliminary for cellular and therapeutic translation.

iRhom2 in Olfaction and Odor-Driven Adaptation
2026-09-14
Azzopardi and colleagues identify iRhom2 as a distinctive regulator in olfactory sensory neurons and connect its expression with odor-dependent changes in olfactory receptor and activity-gene programs. The study combines mouse genetics, transcriptomics, in situ hybridization, and an ectopic receptor model to propose an iRhom2/ADAM17-linked feedback mechanism, while also defining important limits on causal interpretation.
