Inhibition1

  • Exposure order blocks unfamiliar immune cells through receptor-specific inhibitory signals

    Where this hypothesis actsUnfamiliar T cells during their founding activation window in the presence of familiar peptide–MHC ligands

    What is proposedSuppress antagonistic TCR signaling while preserving productive recall stimulation

    With whatProtein or peptide as the agent

    HowSubstitute familiar peptides with variants outside the unfamiliar TCR's mapped antagonist region while retaining equivalent recall stimulation

    Possible resultPossible abolition of the order-dependent persistence deficit in unfamiliar T-cell clones

Rhythm restoration1

  • Incoming immune cells disrupt resident cells’ antiviral signaling through long pauses

    Where this hypothesis actsProtective tissue residents encountering sparse antigen at latent-virus reservoirs during successor recruitment

    What is proposedRestore temporal reliability and reduce prolonged gaps in productive signaling

    With whatNot stated in the record

    HowMake inhibitory contacts less intermittent while retaining their integrated magnitude and matching mean signaling in a calibrated ex vivo system

    Possible resultPossible improvement in local viral control through fewer long signaling gaps
