Could cross-reactivity rescue Foxp3+ regulatory T cell precursors from thymic deletion?

Abstract:

:Thymocytes that bind with high affinity to peptides displayed by MHC class II (pMHC-II) are deleted while low-affinity binders differentiate into naive CD4+ T cells. However, Foxp3+ regulatory T cells (Tregs) seem to defy this binary choice as their precursors require high-affinity interaction with pMHC-II for maturation in the thymus. Here, we rely on the antigen-specific interpretive framework, SPIRAL (Specific ImmunoRegulatory Algorithm), to propose that Tregs escape thymic deletion by forming dyads with IL-2-producing T cells via antigen cross-reactivity. This interpretation reconciles contradictions related to Treg ontogeny in the thymus and their role in modulating antigen-specific immune responses.
