Two-photon microscopy, combined with chemotaxis assays, synchronized thymocyte selection studies, and flow cytometry analyses, reveal that CCR4 and CCR7 promote medullary entry and central tolerance of immature and mature post-positive selection thymocyte subsets, respectively, with distinct outcomes for central tolerance.

pYtags are novel biosensors that can be used to measure the activity of a receptor tyrosine kinase of interest in live cells with high spatiotemporal resolution and are applied to reveal rapid activity dynamics of EGFR/ErbB2 signaling.

The adaptor protein Grb2 is able to enhance the activity of the cytoplasmic tyrosine kinase Btk through a novel mechanism, revealing a new role for Grb2 in B-cell signaling.

Gene editing to generate precisely matched primary human T cell populations demonstrates that the common autoimmune risk allele in the tyrosine phosphatase, PTPN22, promotes signaling in cells expressing a low-avidity, self-reactive TCR specific for a diabetes-associated self-antigen.

A high-throughput method to profile tyrosine kinases and phosphotyrosine recognition domains reveals new rules for sequence specificity and maps the effects of mutations on the recognition of tyrosine phosphorylation sites.

Transcriptional analyses provide an atlas of how traumatic brain injury and aging shape meningeal cell composition and gene expression.

Cell-intrinsic ceramide concentrations are involved in T cell differentiation and function.

A light-controllable ligand is used to probe where in the signaling cascade T cells discriminate self from non-self.

Eutherian CD4 evolved counterbalancing motifs in the extracellular, transmembrane, and intracellular domains that regulate CD4⁺ T cell responses to peptide antigens presented by class II MHC (pMHCII).

PTPN22 function is regulated by reactive oxygen species, and redox regulation of PTPN22 impacts T-cell-dependent autoimmune inflammation.
