Keratinocyte Models for NLRP1 Inflammasome Studies
2026-08-13
Wang, Yazdi, and Panayotova systematically compared primary keratinocytes with HaCaT, HaSKpw, and SVTERT cells for detecting NLRP1 inflammasome activation. Their results show that immortalized models may display stimulus-associated cell death without producing readily measurable NLRP1 activation, supporting primary keratinocytes as the preferred model for mechanistic studies.

Thymosin-β4 Activates Notch/NF-κB in Limb Ischemia
2026-08-11
Lv et al. show that thymosin-β4 enhances endothelial viability, migration, and angiogenic activity in vitro and promotes vascular marker expression in a mouse critical limb ischemia model. Pharmacological inhibition of Notch or NF-κB signaling attenuated these effects, positioning the Notch/NF-κB axis as a mechanistic link between thymosin-β4 and ischemic neovascularization.

hiPSC Intestinal Organoids for Pharmacokinetic Studies
2026-08-10
Saito and colleagues developed a direct three-dimensional culture strategy for generating expandable intestinal organoids from human induced pluripotent stem cells. The organoids could be cryopreserved, differentiated into intestinal epithelial cell types, and used to assess CYP3A-mediated metabolism and P-glycoprotein activity, addressing limitations of animal models and Caco-2 monolayers.
