Porcine rotavirus mainly infects primary porcine enterocytes at the basolateral surface
Intestinal epithelium functions as a barrier to protect multicellular organisms from the outside world. It consists of epithelial cells closely connected by intercellular junctions, selective gates which control paracellular diffusion of solutes, ions ...

The treatment of diseases that attack the brain is very difficult, because the delivery of drug molecules to the brain is often hindered by the blood-brain barrier (BBB). So that the drug delivery is not right on the target cell.

Computing the Threshold of the Influence of Intercellular Nanotubes on Cell-to-Cell Communication Integrity [PDF]
We examine the threshold of the influence of the tunneling nanotubes (TNTs) on the cell-to-cell communication integrity. A deterministic model is introduced with the Michaelis-Menten dynamics and the intercellular exchange of substance. The influence of TNTs are considered as a functional perturbation of the main communication and treated as the matrix

Effects of reduced discrete coupling on filament tension in excitable media [PDF]
Wave propagation in the heart has a discrete nature, because it is mediated by discrete intercellular connections via gap junctions. Although effects of discreteness on wave propagation have been studied for planar traveling waves and vortexes (spiral ...

Gap junctions transmit electrical signals in neurons and serve metabolic coupling and chemical communication. Gap junctions are made of intercellular channels with large pores, allowing ions and small molecules to permeate.

Intracellular calcium ([Ca2+]i) is a second messenger molecule critical for numerous intracellular signaling pathways in endothelial cells (ECs). Direct mechanical stimulation imposed on single ECs by a microprobe has been demonstrated to increase [Ca2 ...

Optimality of intercellular signaling: direct transport versus diffusion [PDF]
Intercellular signaling has an important role in organism development, but not all communication occurs using the same mechanism. Here, we analyze the energy efficiency of intercellular signaling by two canonical mechanisms: diffusion of signaling molecules and direct transport mediated by signaling cellular protrusions.

Hydraulic fracturing in cells and tissues: fracking meets cell biology [PDF]
The animal body is fundamentally made of water. A small fraction of this water is freely flowing in blood and lymph, but most of it is trapped in hydrogels such as the extracellular matrix (ECM), the cytoskeleton, and chromatin.

PP2A-B55alpha controls keratinocyte adhesion through dephosphorylation of the Desmoplakin C-terminus
Critical for the maintenance of epidermal integrity and function are attachments between intermediate filaments (IF) and intercellular junctions called desmosomes.
