Developmental checkpoints in stem/progenitor cells are critical to the determination, commitment and differentiation into distinct lineages. Cancer cells often retain expression of lineage-specific checkpoint proteins, but their potential impact in cancer remains elusive. T lymphocytes mature in the...

Cross-linking mass spectrometry and Targeted cross-linking mass spectrometry for a TCR blocking human monoclonal antibody targeting HLA-A*11:01
ORGANISM(S): Homo Sapiens (human) 
To identify the molecular bases for divergence in differentiation programs of naïve CD8 T cells, we monitored gene expression profile of CD8+ T cells from BM3.3 transgenic mice during responses to TCR ligands of different avidity (full response with antigen presenting cells from C57BL/6 mice , parti...

LQF of 3x FLAG PTPN22 WT Jurkat cells compared to S325A and S325E KI mutant Jurkat cells. WT or KI lines were stimulated with or without TCR engagement for 5 min.

Differentiating PD-1 + TCF-1 + stem-like CD8 T cells towards a distinct effector T cell population with enhanced anti-tumor and anti-viral efficacy by delivering an engineered IL-2 variant through PD-1 mediated cis-targeting; Single time point at termination (day 3 after 2nd Ab therapy); Tumor model...

3x FLAG tagged PTPN22 were immunoprecipitated from Jurkat cells stimulated by TCR for 5min, and the proteins were eluted by FLAG peptides. This study aims to explore the phosphorylation sites on PTPN22 phosphatase, identifying two phosphorylation sites Ser325 and Ser449.

Notch1 signaling is an important regulator of cell fate in early stages of T cell development. Because Notch receptors can function redundantly, we sought an approach for inhibiting all endogenous Notch signaling in thymocytes. Upon ligand engagement, Notch receptors undergo two successive proteo...

Processed single-cell datasets from Pdcd1-CreERT2 × Rosa26-tdTomato fate-mapping mice bearing subcutaneous LLC allografts and treated with CTX, anti-PD-1, or both. We provide count matrices, cell-level annotations, and per-cell TCR clonotypes; raw reads for transcriptome, sample-tag, and TCR librari...
