In plants, programmed cell death (PCD) is a genetically controlled pathway that eliminates specific cells. It is an integral part of the plant life-cycle from embryogenesis to senescence, and drives ...
Dec. 18, 2024 — Scientists have generated human stem cell models which contain notochord -- a tissue in the developing embryo that acts like a navigation system, directing cells where to build ...
Dec. 20, 2024 — Combining bioinformatics and experimetal approaches, researchers have discovered replication hubs for human norovirus, the leading cause of viral gastroenteritis accounting for ...
“Ergothioneine is made by mushrooms and a few microorganisms, but the human body has a mechanism that specifically imports and accumulates ergothioneine in cells and organelles susceptible to ...
Non-selective macroautophagy is stimulated by starvation. Organelle-specific macroautophagy processes such as mitophagy, pexophagy and ribophagy remove damaged organelles.
Receptors are groups of specialised cells. They detect a change in the environment (stimulus) and stimulate electrical impulses in response. Sense organs contain groups of receptors that respond ...
