Human cytomegalovirus (HCMV) replicates in several cell types throughout the body, causing disease absence of an effective immune response. Studies on HCMV require cultured human cells and tissues due to species specificity. In these studies, we investigated impact infection developing three-dimensional cortical organoid tissues, with specific emphasis cell-type-dependent calcium signaling. Calcium signaling is essential function during neural differentiation development. We observed that...

Sonic Hedgehog (SHH) is a driver of embryonic patterning that, when corrupted, triggers developmental disorders and cancers. SHH effector responses are organized through primary cilia (PC) that grow retract with the cell cycle in response to extracellular cues. Disruption PC homeostasis corrupts regulation, placing significant pressure on pathway maintain ciliary fitness. Mechanisms by which robustness ensured SHH-stimulated cells not yet known. Herein, we reveal crosstalk circuit induced...

Mutations in the actin-binding gene Filamin-A have been linked to non-syndromic myxomatous valvular dystrophy and associated mitral valve prolapse. Previous studies by our group traced adult defects back developmental errors interstitial cell-mediated extracellular matrix remodeling during fetal gestation. Mice deficient exhibit enlarged leaflets at E17.5, subsequent progression a phenotype is observed two months. For this study, we sought define mechanisms that contribute degeneration...
