Only three Spike mutations enable murine SARS-CoV-2 infection, which is still strictly ACE2 dependent and causes a COVID-19-like disease in mice with immunopathology-driven lung damage.
The spike protein of SARS-CoV-2 triggers macrophages and epithelial cells to produce excess levels of pro-inflammatory molecules, which can do more harm than good.
Highly specific gene manipulation in mouse thymic epithelial cells (TECs) shows that fine-tuning of β-catenin expression is required for TECs to generate an optimal thymic microenvironment to support T-cell development.

Binding of the translation initiation factor eIF3 to the messenger RNAs encoding the T cell receptor subunits alpha and beta is required to drive a short burst in their translation and promote a strong T cell response.

Infection with Mycobacterium tuberculosis triggers de novo synthesis of polyunsaturated fatty acids by host macrophages, which promote their antimicrobial responses but feed the intracellular pathogen.

A mouse model of inducible inflammasome activation in intestinal epithelial cells reveals separate inflammasome-dependent and -independent cross-presentation pathways for epithelial cell-derived antigen.

Recognition of SARS-CoV-2 spike protein by innate immune sensor TLR2 leads to the induction of inflammatory mediators and constitutes a mechanism for cytokine storm during COVID-19.
Deficiency of capicua, a transcription factor that suppresses autoimmunity, impairs positive and negative selection processes by attenuating TCR signaling in CD4+CD8+ double-positive thymocytes.
