Effect of FTA on the expression of OX40, 4-1BB, and 4-1BBL in bovine PBMCs infected with BVDV.(A) Relative mRNA expression of OX40, 4-1BB, and 4-1BBL cultured with medium alone, FTA, BVDV, and BVDV plus FTA at 24, 48, 72 h in bovine PBMCs. (B) The 4-1BB protein express by western blot (left panels) and ratio of 4-1BB band intensity to that of GAPDH (right panels). 4-1BB protein in PBMCs was collected from the indicated PBMCs cultures at 24, 48, and 72 h after stimulation. Expression of GAPDH was measured as an internal control. Data are presented as the means ± SEM of three independent experiments. *P < 0.05, **P < 0.01, ***P < 0.001.

Background: 4-1BB/TNFRSF9/CD137

4-1BB is an inducible T cell surface protein belonging to the TNF receptor superfamily. It is alternatively known as TNFRSF9, CD137, and ILA. The 255 amino acid human 4-1BB is a type I transmembrane protein having in its extracellular domain four of the cysteine-rich motifs that are characteristic of the TNF receptor superfamily. The 30 kDa glycoprotein exists both as a monomer and as a dimer on T cells. The human and mouse proteins share 60% amino acid identity. 4-1BB is absent from naive T cells, but it is upregulated and continually expressed following T cell activation. The natural ligand, 4-1BBL, is a member of the TNF superfamily and is expressed on activated antigen presenting cells including dendritic cells, macrophages, and B cells. Cross-linking of 4-1BB by 4-1BBL or by agonistic antibodies transmits a potent co-stimulatory signal that enhances the effect of other activating signals such as PHA or anti-CD3 antibodies. 4-1BB signals through the
TFAF2‑NIK pathway resulting in activation of NF-kappa B and ultimately promoting proliferation and survival of T cells.
