Interleukin-23 subunit alpha is a protein that in humans is encoded by the IL23A gene.[5][6] The protein is also known as IL-23p19. It is one of the two subunits of the cytokine Interleukin-23.

Interleukin-23 (IL-23) is a

Interleukin 12 subunit beta, is used by both IL-23 (where it partners with IL-23p19) and IL-12 (where it partners with IL-12A).[5] A functional receptor for IL-23 (the IL-23 receptor) has been identified and is composed of IL-12R β1 and IL-23R.[7]

Function

Produced by

chemokines
resulting in inflammation.

The expression of IL23A is decreased after AHR knockdown in THP-1 cells and primary mouse macrophages.[8]

Clinical significance

Knockout mice deficient in either p40 or p19, or in either subunit of the IL-23 receptor (IL-23R and IL12R-β1) develop less severe symptoms of experimental autoimmune encephalomyelitis (EAE) and inflammatory bowel disease highlighting the importance of IL-23 in the inflammatory pathway.[9][10]

Discovery

A computational search for IL-12 homologue genes found p19, a gene that encodes a cytokine chain. Experimental work revealed that p19 formed a heterodimer by binding to p40, a subunit of IL-12. This new heterodimer was named IL-23.[11]

Knockdown of AHR decreases the expression of IL23A in THP-1 cells and primary macrophage.[8]
