Cholesterol Hinders LNP Intracellular Trafficking
2026-09-08
The 2025 study in the International Journal of Pharmaceutics introduces a sensitive nucleic-acid tracking platform to examine how lipid nanoparticle composition controls endocytic trafficking. Its central finding is that higher cholesterol content promotes peripheral early-endosome accumulation, limiting progression through the endolysosomal pathway and reducing cargo delivery efficiency.

Gepotidacin and Staphylococcus aureus Gyrase
2026-09-04
Gibson and colleagues defined how gepotidacin, a first-in-class novel bacterial topoisomerase inhibitor, targets Staphylococcus aureus gyrase through a cleavage mechanism distinct from that of fluoroquinolones. Biochemical assays and crystal structures showed potent inhibition, stable gyrase–DNA complexes, and predominantly single-stranded DNA break formation, providing a mechanistic framework for developing antibiotics that act at a validated but resistance-prone target.

Morin, AMPD2, and Podocyte Energy Failure
2026-09-02
A 2025 study identifies excessive adenosine 5′-monophosphate deaminase activity, particularly AMPD2, as a mechanistic link between fructose exposure, mitochondrial energy disruption, and podocyte injury. Using podocyte cultures and high-fructose-fed rats, the authors show that Morin reduces metabolic and structural abnormalities, supporting AMPD2 as a candidate target in fructose-associated glomerular damage.
