Let’s explore “Interleukins”

CD40LG encodes CD40 ligand, which binds CD40 and supports communication needed for effective antibody responses. It is on the X chromosome, which changes how some genetic results must be interpreted.

CXCL13 is a chemokine that attracts cells expressing CXCR5, including B cells. This pairing helps organize immune-cell traffic in lymphoid tissues and some chronic inflammatory settings.

CXCL8 is the gene for IL-8, a chemokine involved in recruiting and activating neutrophils. IL-8 is the protein nickname; CXCL8 is the gene name a DNA report may use.

CXCR5 encodes the receptor for CXCL13. This receptor helps guide B cells and certain T cells toward locations where organized immune responses develop.

DDAH1 encodes an enzyme that breaks down asymmetric dimethylarginine, or ADMA. ADMA inhibits nitric oxide synthase; DDAH1 is part of its clearance system, not the inhibitor itself.

HMGB1 normally has functions inside the cell nucleus. When released outside cells in particular settings, it can act as a damage-associated molecular pattern, or DAMP, participating in inflammatory signaling.

IFNG encodes interferon gamma, a cytokine involved in cellular immune defense and activation of macrophages. It differs from the Th2 signals more often emphasized in allergic responses.

IL10 encodes interleukin-10, a cytokine that can limit inflammatory responses and help prevent excessive immune-mediated tissue damage. Immune balance includes resolving a response as well as starting one.

IL12B encodes the p40 subunit shared by IL-12 and IL-23. This makes it an intersection between immune pathways rather than a stand-alone measure of one cytokine.

IL13 encodes interleukin-13, a cytokine involved in Th2 immune responses, mucus-related processes and tissue remodeling. It overlaps with some IL-4 functions but is not the same signal.

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 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.
