OX40/TNFRSF4 Protein, Mouse (Biotinylated, HEK293, His-Avi)
OX40 (TNFRSF4), is a receptor for OX40 Ligand. OX40 is preferentially expressed by T cells. OX40 can be activated by OX40 Ligand, thereby functioning as a T cell co-stimulatory molecule. The OX40-OX40 Ligand interaction promotes effector T-cell survival and effectively induces memory T-cell generation, as well as enhances the helper function of Tfh for B cells, and also promotes the differentiation and maturation of DCs. OX40/TNFRSF4 Protein, Mouse (Biotinylated, HEK293, His-Avi) is a recombinant biotinylated mouse OX40 (V20-P211) with C-terminal Avi and His tag, which is produced in HEK293.

Biological Activity
Description
OX40 (TNFRSF4), is a receptor for OX40 Ligand. OX40 is preferentially expressed by T cells. OX40 can be activated by OX40 Ligand, thereby functioning as a T cell co-stimulatory molecule. The OX40-OX40 Ligand interaction promotes effector T-cell survival and effectively induces memory T-cell generation, as well as enhances the helper function of Tfh for B cells, and also promotes the differentiation and maturation of DCs[1][2]. OX40/TNFRSF4 Protein, Mouse (Biotinylated, HEK293, His-Avi) is a recombinant biotinylated mouse OX40 (V20-P211) with C-terminal Avi and His tag, which is produced in HEK293.
Background
OX40 (TNFRSF4), a member of TNFR superfamily, is a receptor for OX40 Ligand. OX40 is preferentially expressed by T cells, but also found in natural killer T cells, natural killer cells, neutrophils, and human airway smooth muscle cells. Mouse OX40 shares 90% aa sequence identity with rat. Mouse OX40 shares <30% aa sequence identity with human[1].
OX40 Ligand can activate OX40 and thereby functioning as a T cell co-stimulatory molecule. The OX40-OX40 Ligand interaction promotes effector T-cell survival and effectively induces memory T-cell generation, as well as enhances the helper function of Tfh for B cells, and also promotes the differentiation and maturation of DCs[1][2].
The interaction between OX40 Ligand with OX40 is essential for the generation of antigen-specific memory T cells, and induces host antitumor immunity[3]. But the over-upregulation of OX40 and OX40L may induce abnormal activation of Tfh cells and excessive production of autoantibodies, which leads to autoimmune disease[1]. For example, OX40 interacts with OX40 Ligand is critical for Th1 and Th2 responses in mice allergic inflammation[4].
In Vitro
OX4 increases expression of RANTES protein in HUVECs[5].
