tumor necrosis factor --> tumour necrosis factor
(Science: cytokine) Originally described as a tumour inhibiting factor in the blood of animals exposed to bacterial lipopolysaccharide or bacille Calmette-Guerin.
Necrosis (neh-CROH-sis) Unplanned cell death caused by outside circumstances, such as traumatic injury or infection. See apoptosis.
necrosis. Death of tissue accompanied by dark brown discoloration, usually occurring in a well-defined part of a plant, such as the portion of a leaf between leaf veins or the xylem or phloem in a stem or tuber.
Tumor Necrosis Factor-alpha (TNF-α)
Large amounts of TNF-α are quickly released by stimulated mast cells. All the cells involved in inflammation have receptors for TNF-α, and are activated by it to synthesize more on their own.
Necrosis
Morphological changes resulting from cell death caused by enzymatic degradation.
necrosis Cell or tissue death.

nectar A sweet, syrupy exudate produced by some flowers as an attractant for pollinators.

Apoptosis is often induced by activation of death receptors (DR) belonging to the tumor necrosis factor receptor (TNFR) family. Examples are Fas (CD95), TNFR-1 and TNFR-related apoptosis-mediated protein (TRAMP).
The periosteum serves as a nidus for the ramification of the vessels previous to their distribution in the bone; hence the liability of bone to exfoliation or necrosis when denuded of this membrane by injury or disease.
