eIF3e-mediated translational checkpoint maintains immune tolerance and prevents lymphoid malignancy.

These cells, in turn, activate bystander B cells, increase MHC class II expression, and establish a feedforward loop of Eif3e deletion and lymphocyte activation. Despite their hyperactivated state, Eif3e-deficient B cells exhibit impaired proliferation, reduced survival, and defective differentiation.

Cell-count and viability assessment in the study's cell samples used Countstar (model not specified) before single-cell analysis for the immune-cell research.
