Etrolizumab Chemical Properties,Usage,Production
Uses
Etrolizumab (rhuMAb Beta7) is a gut-selective, anti-β7 integrin monoclonal antibody. Etrolizumab is specific targeting of the β7 subunit of α4β7 and αEβ7 integrins with Ki values of 18 nM and 1800 pM for Human α4β7 and Human αEβ7-293, respectively. Etrolizumab can be used in research of inflammatory bowel disease (IBD)[1][2].
in vivo
Etrolizumab (rhuMAb Beta7; 5 mg/kg; i.v.; once; normal female BALB/c mice) decreases β7 integrins on T lymphocytes[2].
Etrolizumab (200 μg (100 μL); i.p.; once) inhibits lymphocyte homing in the CD45RBhigh T cell-reconstituted SCID mouse model of colitis[2].
| Animal Model: | Normal female BALB/c mice (17-21 g)[2] |
| Dosage: | 5 mg/kg |
| Administration: | Intravenous injection; once |
| Result: | Had 98.3% of intraepithelial CD8+ T-cell β7 integrin receptors and 90.0% of intraepithelial CD4+ T-cell β7 integrin receptors after 24 h. |
| Animal Model: | SCID mouse model of colitis[2] |
| Dosage: | 200 μg (100 μL) |
| Administration: | Intraperitoneal injection; once |
| Result: | Blocked lymphocyte recruitment and homing to the inflamed colon. |
IC 50
α4β7; αEβ7
