(Biyoloji) RNA interference (also called "RNA-mediated interference", abbreviated RNAi) is a mechanism for RNA-guided regulation of gene expression in which double-stranded ribonucleic acid inhibits the expression of genes with complementary nucleotide sequences. Conserved in most eukaryotic organisms, the RNAi pathway is thought to have evolved as a form of innate immunity against viruses and also plays a major role in regulating development and genome maintenance
(Tıp, İlaç) Immune-mediated diseases are conditions which result from abnormal activity of the body's immune system. The immune system may over-react (for example, immune-mediated contact dermatitis) or start attacking the body (for example, autoimmune hemolytic anemia). Autoimmune diseases are a subset of immune-mediated diseases
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is a process of passive transport (as opposed to active transport), with this passive transport aided by integral membrane proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism
(Biyoloji) Receptor-mediated endocytosis (RME), also called clathrin-dependent endocytosis, is a process by which cells internalize molecules (endocytosis) by the inward budding of plasma membrane vesicles containing proteins with receptor sites specific to the molecules being internalized

If someone mediates between two groups of people, or mediates an agreement between them, they try to settle an argument between them by talking to both groups and trying to find things that they can both agree to.
