PLGA Microspheres for Controlled Corticosteroid Delivery
2026-09-30
This 2026 Pharmaceutics study shows that PLGA microsphere size, surface chemistry, and ester stability jointly control corticosteroid transport through articular cartilage. Its combination of bovine explants, HPLC-based degradation analysis, and transport modeling provides a practical framework for designing more predictable intra-articular delivery systems.

Biomimetic Models for Pulmonary Drug Permeability
2026-09-29
This 2025 study compares mass-spectrometry-coupled immobilised artificial membrane liquid chromatography and open-tubular capillary electrochromatography as biomimetic models of pulmonary drug permeability. Its findings clarify when each platform reflects lipid partitioning, electrostatic interactions, and structural effects, supporting more informed high-throughput screening in respiratory drug research.

PXDN–LDHA Signaling Drives Glioblastoma Glycolysis
2026-09-29
The reference study identifies PXDN as a glycolysis-associated driver of glioblastoma progression and links its effects to LDHA expression. By combining transcriptomic network analysis with cellular and in vivo validation, the work provides a mechanistic framework for studying PXDN–LDHA signaling while highlighting important limits for clinical translation.

Mouse Lung Organoid Kit: Lung-Targeted RNA Models
2026-09-28
The Mouse Lung Organoid Kit provides a biologically relevant framework for evaluating lung-targeted RNA delivery beyond simple monolayers. This article explains how organoid assays can translate the tripod-like lipid findings from a recent LNP study into more informative decisions about uptake, editing, toxicity, and experimental progression.

Adipose-Neural Signaling in EAT-Related Arrhythmia
2026-09-28
Fan et al. use a stem cell-based coculture model to show how epicardial adipose tissue may promote arrhythmia through a leptin–sympathetic neuron–NPY pathway, with downstream Y1R, NCX, and CaMKII involvement. Patient observations support the clinical relevance of this axis, while the study’s intervention results identify candidate mechanisms rather than established treatments.

Recombinant Human IL-15 for T-Cell Workflows
2026-09-27
Build reproducible T-cell and NK-cell culture assays with a defined, tag-free cytokine and a concentration range anchored to the product’s reported bioactivity. The guide also explains how IL-15 can support cell-handling workflows around CREATE gene-editing studies—without confusing a culture supplement with an editing component.

Cleavage-Resistant TREM2 Restores Macrophage Efferocytosis
2026-09-26
Dong et al. engineered a cleavage-resistant TREM2 receptor that preserves and amplifies macrophage signaling when inflammation promotes ADAM17-mediated receptor shedding. In mouse models of MASH and atherosclerosis, macrophage-targeted delivery of its mRNA improved apoptotic-cell clearance and reduced inflammation, providing a therapeutic proof of concept that still requires further validation.

Diclofenac Organoid Assays: Separate Exposure from Effect
2026-09-25
Diclofenac organoid assays can reveal how intestinal exposure and cyclooxygenase inhibition shape inflammatory readouts—but only when pharmacokinetics are distinguished from pharmacodynamics. This article develops an assay-interpretation framework grounded in human iPSC-derived intestinal organoid research.

Vitamin C (Ascorbic Acid): Research Evidence
2026-09-25
Vitamin C (ascorbic acid) is a water-soluble research compound studied in cancer models and in a cellular model of cochlear senescence. The available evidence includes dose-associated CT26 tumor-cell effects reported in product information and a 2024 study linking protection of D-galactose-treated HEI-OC1 cells to reduced ROS/NF-κB signaling.

ERAD Hijacking Enables Membrane Protein Degradation
2026-09-24
Song et al. introduce ERAD-engaging chimeras (ERADECs), a targeted protein degradation strategy that redirects the ER-associated degradation machinery to selected proteins, including transmembrane PD-L1. The study reports potent PD-L1 degradation and tumor-suppression effects in vivo, while also indicating that the approach may extend beyond membrane targets; its broader utility and translational scope still require careful evaluation.

Amiloride (MK-870): A Boundary Test for Endocytosis
2026-09-24
Amiloride (MK-870) is a useful probe for sodium-channel physiology, but its value in uptake studies depends on asking the right mechanistic question. This article interprets a negative amiloride result in grass carp reovirus research and shows how to use inhibitor evidence without overclaiming pathway specificity.

Hydrocortisone Butyrate: From GR Biology to Delivery
2026-09-23
Hydrocortisone butyrate offers a useful way to investigate glucocorticoid receptor biology in skin inflammation models. New PLGA microsphere findings add a translational dimension: particle size and surface chemistry can shape corticosteroid transport and ester stability, reminding researchers to measure exposure as carefully as biological response.

Cepharanthine Inhibits Endometriosis in Organoids and Mice
2026-09-23
The reference study evaluates Cepharanthine, a biscoclaurine alkaloid, across immortalized stromal cells, patient-derived endometrial organoids, and a murine peritoneal endometriosis model. Its results connect reduced lesion growth with G0/G1 arrest, DNA-damage signaling, impaired DNA repair, and mitochondrial apoptosis, while also illustrating the value of organoids for translational drug testing.

Surrogate BBB Model Corrects Lysosomal Trapping
2026-09-22
Hu and colleagues developed a high-throughput blood-brain barrier surrogate using paired LLC-PK1-MOCK and LLC-PK1-MDR1 Transwell cultures. By combining permeability, efflux, recovery, and lysosomal-trapping correction, the model improved prediction of unbound brain distribution and offered a practical strategy for early CNS drug screening.
