Summary
GP(33-41) TFA, a 9-aa-long peptide, is the optimal sequence of the GP1 epitope of lymphocytic choriomeningitis virus. GP(33-41) TFA can upregulate H-2D b molecules at the RMA-S (Db Kb) cell surface with a SC 50 of 344 nM [1] .
In Vitro
GP(33-41) TFA sensitizes MC57 and T2-D
b
cells to lysis with ED
50
s of 0.9±0.6 and 2.5±0.7 nM

.
The interaction between T cell receptors (TCR) and peptide-major histocompatibility complex (pMHC) antigens can lead to varying degrees of agonism (T cell activation), or antagonism. The P14 TCR recognises the lymphocytic choriomeningitis virus (LCMV)-derived peptide, GP(33-41) (KAVYNFATC), presents in the context of H-2D
