These findings may have implications for the in vivo interactions of PMNL with vascular endothelium, depending on whether the endothelium is exposed to IL-1 of TNFα via the blood on the luminal (apical) surface or via the extravascular space on the abluminal (basal) surface. 展开 关键词: ...
show that basal stem cell progeny seamlessly integrate into a physiologically active barrier epithelium by gestating their future apical surface in a sheltering niche created by a transient occluding junction.doi:10.1038/s41556-023-01116-wAnthony,Galenza...
Our theoretical model to calculate the apical surface epithelial tension in a polarized epithelium from cell–cell adhesion and steady-state active prestress caused by myosin II activity using frequency shifts requires some critical assumptions. An important assumption is that a polarized confluent sheet ...
2,6, B Corthe´sy7, N Cerf-Bensussan1,2,8 and M Heyman1,2,8 In celiac disease, enhanced permeability to gliadin peptides can result from their apico-basal transport by secretory immunoglobulin A1 (SIgA1) binding to the CD71 receptor ectopically expressed at the gut epithelial surface. ...
5). In DA-tube cells of control egg chambers, βPS-Integrin was present on the basal surface and in basal puncta (Fig. 5E and G), and sub-basally on lateral membranes and in large, cytoplasmic puncta (Fig. 5E’ and G’). In DA-tube cells of brL>shi[K44A] egg chambers, we ...
Furthermore, as described above, the current sources oriented radially with respect to the head surface can be picked up only by EEG but not by MEG, while the tangentially oriented sources can be recorded by both EEG and MEG. With regard to the excitatory vs. inhibitory synaptic activity, ...
After the spo- rophytic apical cell ceases its activity, an intercalary region, called the seta, gains meristematic activity and promotes growth of the sporophyte body along the apical-basal axis. Finally, a sporangium is formed on the upper part of the sporophyte body and numerous spores are ...
development of root system: the cell division at the primary root (PR) meristem to add new cells enabling root growth; the generation of lateral roots (LR) to increase the exploratory capacity of the root system; the enlargement of the total surface of PR and LRs through root-hair growth ...
The SA cines (a,c) and three-chamber (b,d) images of a 53-year-old woman with HOCM. High-speed blood flow (white arrow) can be seen in the narrow left ventricular outflow tract preoperatively. The obstruction is relieved after TA-BSM. Part of the basal anterior ventricular septum my...
