An obstacle to use of HBE-ALI models for high throughput screening (HTS) has been the severely limited supply of tissue samples from patients with unusual CFTR mutations. We have developed a plate for highly miniaturized, arrayed HBE-ALI cultures suitable for use in automated drug screening and mechanistic studies (μALI Plate). Cells cultured on the μALI Plate exhibit hallmarks of HBE biology including beating cilia and mucus production, but require less than one tenth the number of cells compared to conventional Transwell filters. Cells grown in this manner can be visualized directly from the apical surface by immunohistochemistry without the requirement to image through a filter support. Primary cells grown on the μALI Plate will be useful for testing therapeutic interventions directed towards patients with uncommon CFTR variants. Studies of ion channel function, cilia beat frequency and airway surface liquid depth are currently underway. Among other things, the μALI technology has the potential to facilitate personalized approaches to CF therapy, including drug development.

Inhibition of The Auto-inflammation Suppressor Protein ISG15 Triggers Preeclampsia by Blocking Trophoblast Migration and InvasionPoster
In summary, ISG15 expression levels are crucial for trophoblast morphology and function (migration/invasion). By blocking trophoblast invasion, reduced ISG15 levels could contribute to impaired spiral artery transformation that reduces utero-placental blood flow in preeclampsia. Thus, agents inducing ISG15 expression are likely to be therapeutic in preeclampsia.
