HT1080/4-1BB Stable Reporter Cell Line

Functional analysis of 4-1BBL on HT1080/4-1BB cells by measuring IL-8 release.

HT1080/4-1BB Stable Reporter Cell Line

4-1BB is a member of the tumor necrosis factor (TNF) receptor family. Its alternative names are tumor necrosis factor receptor superfamily member 9 (TNFRSF9), CD137 and induced by lymphocyte activation (ILA). It is currently of interest to immunologists as a co-stimulatory immune checkpoint molecule. 4-1BB can be expressed by activated T cells, but to a larger extent on CD8 than on CD4 T cells. In addition, CD137 expression is found on dendritic cells, follicular dendritic cells, natural killer cells, granulocytes and cells of blood vessel walls at sites of inflammation. The best characterized activity of 4-1BB is its costimulatory activity for activated T cells. Crosslinking of 4-1BB enhances T cell proliferation, IL-2 secretion, survival and cytolytic activity. Further, it can enhance immune activity to eliminate tumors in mice.

HT1080 is derived from human fibrosacoma biopsy. It is highly active in NF-kB signaling pathway which is necessary for immune responses. HT1080 cells overexpressed with 4-1BB are significantly increased in immune response indicated by elevated production of IL-8.
