Research reveals TLR4 regulates thymic regeneration and lymphocyte output via HSP70-mediated efferocytosis.

This research investigates the role of TLR4 in thymic macrophages and its impact on thymic homeostasis and T cell output.
Utilized inbred mouse strains to examine thymic size and regeneration.
Applied bulk RNA-seq and CUT&RUN profiling to analyze macrophage transcriptional changes.
Employed mass spectrometry to identify TLR4-interacting proteins.
C3H/HeJ mice displayed reduced thymic size and regeneration after injury compared to Tlr4-competent strains.
HSP70 was identified as a protein interacting with TLR4, influencing macrophage efferocytosis.
Therapeutic activation of TLR4 using MPLA enhanced thymic cellularity and efferocytosis.

Lemarquis et al. (2025) studied this question.
