interleukin 1 beta


The protein encoded by IL1B is a member of the interleukin 1 cytokine family. IL-1B is a potent proinflammatory cytokine and important mediator of immune responses mainly produced by monocytes and macrophages. IL-1B activates immune cells such as CD4 and CD8 T cells, upregulates expression of adhesion molecules, and induces expression of a number of other proinflammatory cytokines and other inflammation-associated proteins.


Protein expression analysis

Bone marrow cell supernatant from both wild type (WT) C57BL/6 and Heterozygous B-hIL1B mice were analyzed by ELISA.

When treated with LPS, mouse IL1B was detectable in the WT mice and heterozygous B-hIL1B mice, while human IL1B was detectable in the heterozygous B-hILIB mice, albeit being at a lower level. ND, not detectable. n=3.

Strain specific IL1B expression analysis in homozygous B-hIL1B mice by ELISA.

Bone marrow cell supernatant were collected from WT and  homozygous B-hIL1B mice stimulated with LPS in vivo, and analyzed by ELISA with species-specific IL1B ELISA kit. Mouse IL1B was detectable in WT mice.Human IL1B was exclusively detectable in heterozygous B-hIL1B mice but not WT mice. ND, not detectable.
