Paracellular transport refers to the transfer of substances across an epithelium by passing through the intercellular space between the cells. [1] It is in contrast to transcellular transport , where the substances travel through the cell, passing through both the apical membrane and basolateral membrane .
In contrast, paracellular transport is the transfer of substances across an epithelium by passing through an intercellular space between the cells. It differs from transcellular transport, where the substances travel through the cell passing through both the apical membrane and basolateral membrane; Renal physiology. Transcellular transport is ...
Solvent drag, also known as bulk transport, refers to solutes in the ultrafiltrate that are transported back from the renal tubule by the flow of water rather than specifically by ion pumps or other membrane transport proteins. [1] This is a phenomenon primarily in renal physiology, but it also occurs in gastrointestinal physiology.
Two routes of Ca 2+ absorption are recognized: paracellular transport and transcellular transport (see Figure 4). [55] A high-Ca 2+-diet favors paracellular transport of the ion across the length of the intestine allowing them to pass between the intercellular tight junctions that connect epithelial cells.
WASHINGTON (Reuters) -A massive winter storm moving across the United States will not keep the U.S. Congress from meeting on Monday to formally certify Republican Donald Trump's election as ...
Perhaps the most famous group of spiders that construct funnel-shaped webs is the Australian funnel-web spiders. There are 36 of them and some are dangerous as they produce a fast-acting and ...
Tiny plastic particles have been found throughout the human body, but researchers say they’re just starting to understand the impact.
Although classically known for their role in the prevention of paracellular transport, tight junction proteins also play crucial roles as signaling molecules. Occludin is able to interact with signaling pathways controlling cellular differentiation, and has been shown to travel to the nucleus of cells in which the tight junction has been disrupted.
