Figure 1 The inhibitory effect of mAbs 5G7, 14F10 and 1A11 on BACE1 in the BACE1 MBP-C125Swe experiment. The substrate is the fusion protein of maltose binding protein (MBP) and the carboxy-terminal 125 amino acids of human APP containing the Swedish double mutation, and the IC50 is three The mAbs were 0.47 nM (5G7), 0.46 nM (14F10) and 0.76 nM (1A11).
Figure 2 The regulation of BACE1 activity in the mcaFRET experiment, the substrate is the small molecule FRET peptide MCA-SEVENLDAEFRK(Dnp)-RRRR—NH2, the IC50 (or EC50) of the three mAbs are 0.06 nM (5G7), 1.6 nM (14F10 ) and 0.38 nm (1A11).
Figure 3 MAb 1A11 inhibits BACE1 activity in SH-SY5Y/APPwt cells. SH-SY5Y/APPwt cells were treated with 300 nM MAbs 1A11, 5G7 and 14F10 in PBS. PBS was used as negative control, while complex BACE1 inhibitor was used as positive control (CT+). After 24 hours of treatment, Aβ and sAPPβ in the conditioned medium were analyzed by Western blot, and MAb 1A11 treatment reduced the production of Aβ and sAPPβ.
Figure 4 MAb 1A11 inhibits BACE1 activity in primary cultured mouse neurons.
Primary cultured neurons were transduced with human APPwt by Semliki forest virus and treated with 100 nM MAb 1A11, MAb 5G7 and MAb 14F10 (dissolved in PBS). PBS was used as a negative control, while a BACE1 compound inhibitor was used as a positive control. After 24 hours of treatment, conditioned media and cell extracts were analyzed by Western blot. MAb 1A11 treatment strongly inhibited the production of Aβ, sAPPβ and CTFβ.
Figure 5 Antigen-binding fragment (Fab) of MAb 1A11 inhibits BACE1 activity in primary cultured mouse neurons.
Primary cultured neurons were transduced with human APPwt by Semliki forest virus and treated with 200 nM Fabs produced by MAb 1A11, MAb 5G7 and MAb 14F10 (dissolved in PBS). After 24 hours of treatment, conditioned media and cell extracts were analyzed by Western blot. The Fab of MAb 1A11 strongly inhibits the production of Aβ, sAPPβ and CTFβ.
