"Paracellular" Pronounce,Meaning And Examples

"Paracellular" Meaning

The term "paracellular" refers to the movement of molecules or ions across a cell membrane through the spaces between cells, rather than through the cell membrane itself. In other words, it describes the diffusion of substances through the intercellular clefts or tight junctions, which are the areas between adjacent cells where the cell membranes are tightly apposed. This process is important in many physiological and pathological contexts, including the transport of nutrients and waste products across epithelial barriers, the regulation of blood pressure, and the progression of certain diseases.

"Paracellular" Examples

Paracellular

The term "paracellular" refers to the space between epithelial cells, where substances can pass through. Here are five usage examples:

In this type of filter, the pores are designed to allow molecules to pass through the paracellular space, while blocking larger particles. ([Engineering context])
The team used confocal microscopy to visualize the paracellular pathway of uptake of nanoparticles by epithelial cells. ([Scientific context])
The discovery of the paracellular pathway of sugar transport revolutionized our understanding of nutrient absorption. ([Medical context])
The researchers proposed that the paracellular clearance of toxins could be an effective treatment for certain diseases. ([Scientific context])
