Tebentafusp
Based on 1 publication(s) in Google Scholar
Tebentafusp (IMCgp100) is a bispecific fusion protein to target gp100 peptide-HLA-A*02:01 (a melanoma-associated antigen). Tebentafusp guides T cells to kill gp100-expressing tumor cells via a high affinity T-cell receptor (TCR) binding domain and an anti-CD3 T-cell engaging domain. Tebentafusp leads to inflammatory cytokines and cytolytic proteins production, resulting in the direct lysis of tumour cells.

体外実験
Tebentafusp is an ImmTAC recognizing a peptide derived from the melanoma-specific protein, gp100, presented by HLA-A*0201[3].
Tebentafusp (31 pM, 82 pM, and 131 pM; 16 h) stimulates cytotoxic degranulation activity of PBMC against Mel526 cells rather than gp100-negative A375 cells[3].
Tebentafusp (100 pM; 0-50 h) mediates CD8+ T cell killing despite the presence of regulatory T cells via monitoring caspase 3/7 activation during 40-48 hr[3].
Tebentafusp (100 pM; 0-80 h) triggers cytolysis of melanoma cells by CD4+ T cell subpopulations[3].
Tebentafusp (1, 12, 31, 82, and 131 pM; 24 h or 96 h) increases granzyme B amount, and induces broad cytokine and chemokine release including in both CD4+ and CD8+ cells[3].

Loaded HLA-A*0201 GP100 Complex Protein, Human (Biotinylated, YLEPGPVTA, HEK293, His-Avi, HY-P77754) on NTA biosensor, can bind Tebentafusp with an affinity constant of 7.761E-10 M as determined in BLI assay. -
Flow cytometric analysis of 1×106 Jurkat cells labelling CD3E (red) with Tebentafusp (HY-P99339). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Goat Anti-Human IgG H&L (AF488) (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG1 kappa Isotype Control (HY-P99001, blue) was used as the isotype control.
