CTLA4 Signaling Pathway
CTLA4 (cytotoxic T-lymphocyte–associated antigen 4, aka CD152) is a transmembrane
protein member of the immunoglobin superfamily. This protein receptor plays a key role in
downregulating immune responses (e.g. inhibit T-cell activation).
Since CTLA4 has a much higher affinity for B7, this competitive binding could prevent signals from CD28-B7 binding.
CTLA4 may also inhibit T-cell activation through the dephosphorylation of TCR-signaling
proteins or the interference with Akt signaling.

ProSci has developed SARS-CoV-2 pseudoviruses with a luciferase reporter allowing researchers to
quickly build their own neutralization and inhibitor interaction assays. These pseudovirues have
been engineered to lack the appropriate coding for the virus to replicate.
