Autolus Therapeutics Announces Publication in Molecular Therapy Nucleic Acids
One such inhibitory factor is Fas ligand (FasL), which binds to the Fas receptor (CD95) on the surface of an activated T cell and triggers the CAR T cell to die by apoptosis.
- One such inhibitory factor is Fas ligand (FasL), which binds to the Fas receptor (CD95) on the surface of an activated T cell and triggers the CAR T cell to die by apoptosis.
- The research group at Autolus tested several Fas chimeras which consist of the extracellular domain of Fas fused to the intracellular domain from different TNF receptor superfamily members.
- Expression of these chimeras in a CAR T cell not only blocks apoptosis triggered by FasL, but results in co-stimulation, which promotes CAR T cell survival and proliferation.
- These data support the potential of this Fas-CD40 chimera to render T cell therapies resistant to FasL-mediated cell death and improve their effectiveness against solid tumors.
