Human Interleukin-36 Alpha, IL1F6 ELI

Cytokine that binds to and signals through the IL1RL2/IL-36R receptor which in turn activates NF-kappa-B and MAPK signaling pathways in target cells linked to a pro-inflammatory response.

Part of the IL-36 signaling system that is thought to be present in epithelial barriers and to take part in local inflammatory response; similar to the IL-1 system with which it shares the coreceptor IL1RAP.

Seems to be involved in skin inflammatory response by acting on keratinocytes, dendritic cells and indirectly on T-cells to drive tissue infiltration, cell maturation and cell proliferation.

In cultured keratinocytes induces the expression of macrophage, T-cell, and neutrophil chemokines, such as CCL3, CCL4, CCL5, CCL2, CCL17, CCL22, CL20, CCL5, CCL2, CCL17, CCL22, CXCL8, CCL20 and CXCL1, and the production of proinflammatory cytokines such as TNF-alpha, IL-8 and IL-6.

In cultured monocytes upregulates expression of IL-1A, IL-1B and IL-6.

In myeloid dendritic cells involved in cell maturation by upregulating surface expression of CD83, CD86 and HLA-DR.

In monocyte-derived dendritic cells facilitates dendritic cell maturation and drives T-cell proliferation.

May play a role in proinflammatory effects in the lung.
