After the introduction of the slow Wallerian degeneration mouse mutant, it is now believed that neurite degeneration is not a passive process but instead an active process that becomes activated once a threshold of parameters is met.
Morula cells contain inactive prophenoloxidase inside intracellular vacuoles that becomes activated during the process [12], producing melanin, which accumulates as brownish color dots in confined areas of the tunic between interacting ampullae.
The endothelium lining the blood vessels becomes activated during the inflammatory process, resulting in the production of several mediators, the expression of endothelial adhesion molecules, and increased vascular permeability (leakage).
Mechanistically, we showed that FAK becomes activated with TGF-β-mediated induction of EMT, a process that is dependent on Src and β3 integrin.
Once inside the cell, cisplatin becomes activated by the substitution of one or two chloride atoms by water, a process known as aquation.
In complex II, caspase-8 becomes activated and initiates apoptosis.
Receptor (R) binds ligand (L) and becomes activated (RL).
Upon binding of its ligand, Delta4, this receptor becomes activated.
A naïve T cell becomes activated after it encounters antigen.
FAK becomes activated when it is phosphorylated at tyrosine 397 (Y397).
