Teplizumab (MGA-031) is a Fc receptor non-binding anti-human CD3 monoclonal antibody. Teplizumab reduces the loss of beta-cell function. Teplizumab can be used in the research of type 1 diabetes[1][2].

Target	CD3[1]
In Vitro	Teplizumab (10 ng/mL-10 μg/mL, 5 days) induces human CD8+ T-cell proliferation[3]. Teplizumab (6 days) increases the expression of CD25 and intracellular CTLA4 on CD8+ cells (freshly isolated PBMCs)[3]. Cell Proliferation Assay[1] Cell Line: Human PBMCs Concentration: 10 ng/mL, 100 ng/mL, 1 μg/mL, 10 μg/mL. Incubation Time: 5 days Result: Induced cell proliferation (measured by incorporation of [3H]thymidine in a 5-day assay.
In Vivo	Teplizumab (0.24 mg/kg, i.p.) induces migration of human CD4 T cells to the lamina propria and ablated the treatment effects of the drug on graft survival in NSG mice[2]. Animal Model: NOD/SCID IL2γc-/- (NSG) mice (a tolergenic humanized mouse model)[1] Dosage: 0.24 mg/kg, 5 μg Administration: Intraperitoneal injection (i.p.) Result: Decreased CD4:CD8 ratio in the peripheral blood from 2.03 to 1.01, p < 0.05. Decreased circulating hCD4 cells in the peripheral blood. Decreased in the proportion of T cells in the bone marrow and lung. Increased in the total number of human CD45+ cells infiltrating the lamina propria of the small intestine.
