IL15

Related reading

IL15 encodes a cytokine involved in the survival and activity of immune cells, including natural killer cells and memory CD8 T cells. Its receptor system includes IL15RA.

IL15RA

Related reading

IL15RA encodes the alpha receptor component for IL-15. It helps present IL-15 to responding immune cells, supporting communication that is important for particular lymphocyte populations.

Gene referenceSep 23, 2026

IL16

Related reading

IL16 encodes interleukin-16, a cytokine involved in attracting and influencing immune cells, including CD4-expressing cells. Its recruitment role helps separate it from other numbered interleukins.

Gene referenceSep 23, 2026

IL17A

Related reading

IL17A encodes interleukin-17A, a cytokine involved in defense at tissue barriers and inflammatory signaling. It belongs to the Th17 pathway, which is supported by signals including IL-23.

Gene referenceSep 23, 2026

IL18

Related reading

IL18 encodes interleukin-18, a cytokine that can promote interferon-gamma responses in the appropriate immune context. Its receptor includes components encoded by IL18R1 and IL18RAP.

Gene referenceSep 23, 2026

IL1B

Related reading

IL1B encodes interleukin-1 beta, a cytokine involved in inflammatory responses and fever. Its production and activation are regulated processes, not simply an on/off consequence of having a common SNP.

Gene referenceSep 23, 2026

IL22

Related reading

IL22 encodes a cytokine that acts on tissues such as epithelial barriers. It can support barrier defense and repair, while its effects depend on the tissue and inflammatory setting.

Gene referenceSep 23, 2026

IL2RA

Related reading

IL2RA encodes the alpha chain of the interleukin-2 receptor, also called CD25. It is involved in immune activation and regulatory T-cell biology; a soluble receptor measurement is distinct from a DNA result.

Gene referenceSep 23, 2026

IL33

Related reading

IL33 encodes interleukin-33, a signal that can act as an alarmin during tissue stress and promote type 2 immune responses. It belongs in a different functional group from chemokines that recruit cells.
