'''Adenosine A2B receptor'''

The '''Adenosine A2B receptor''' (pronounced: a-den-o-seen A2B re-cep-tor), also known as '''ADORA2B''', is a type of [[Adenosine receptor]] that is encoded by the ADORA2B gene in humans.

==Etymology==
The term "Adenosine" is derived from the Greek words "adenos" meaning "gland" and "ine" a suffix used in chemistry to denote a specific type of compound. The "A2B" part of the name refers to the specific subtype of the receptor.

==Function==
The Adenosine A2B receptor is one of four subtypes of adenosine receptors (A1, A2A, A2B, and A3) and has its own unique role in the body. It is activated by the [[neurotransmitter]] adenosine and plays a crucial role in many physiological processes such as [[vasodilation]], [[inflammation]], and [[immune response]].

==Related Terms==
* [[Adenosine]]: A nucleoside composed of a molecule of adenine attached to a ribose sugar molecule.
* [[Receptor (biochemistry)]]: A protein molecule that receives chemical signals from outside a cell.
* [[Neurotransmitter]]: Endogenous chemicals that enable neurotransmission.
* [[Vasodilation]]: The widening of blood vessels.
* [[Inflammation]]: A part of the complex biological response of body tissues to harmful stimuli.
* [[Immune response]]: A reaction of cells and fluids of the organism in response to the presence of a substance which is not recognized as a constituent of the body itself.
