Beta-selection: abundance of TCRbeta-/gammadelta- CD44- CD25- (DN4) cells in the foetal thymus. [PDF]

, 2007
Expression of TCRbeta and pre-TCR signalling are essential for differentiation of CD4- CD8- double negative (DN) thymocytes to the CD4+ CD8+ double-positive (DP) stage.

Disruption of Treg Homeostasis in Rheumatoid Arthritis via Ferroptosis‐Mediated ETC Collapse and TXK‐STAT3/PLCγ1 Activation

Advanced Science, EarlyView.
In rheumatoid arthritis, synovial Tregs accumulate but are functionally impaired due to iron overload‐induced ferroptosis. This triggers mitochondrial dysfunction and TXK tyrosine kinase‐mediated signaling, leading to Treg destabilization and inflammation.

Ex vivo and in vivo CRISPR/Cas9 screenings identify the roles of protein N-glycosylation in regulating T-cell activation and functions

eLife
Cytotoxic CD8+ T-cells play central roles in tumor immunotherapy. Understanding the mechanisms that regulate development, differentiation, and functions of cytotoxic CD8+ T-cells leads to the development of better immunotherapies.

Studies on the role of Coronin 1 and the actin cytoskeleton in T cell signaling and survival [PDF]

, 2009
Calcium ions (Ca2+) function as universal second messengers in most if not all eukaryotic cells, including the cells of the immunesystem. Ca2+ signals are required for the proper activation of lymphocytes, such as T-lymphocytes, their proliferation ...

Pharmacologic Modulation of ARID3A with Rimegepant Reactivates Type I Interferon Signaling and Sensitizes Triple‐Negative Breast Cancer to PD‐1 Blockade

Advanced Science, EarlyView.
This study identifies ARID3A as a key immunosuppressive transcription factor in TNBC. Its inhibition activates the type I IFN pathway, boosting CD8+ T cell infiltration and sensitizing tumors to anti‐PD‐1. The FDA‐approved migraine drug Rimegepant targets ARID3A, enhances immunotherapy efficacy in preclinical models, and establishes a druggable axis to

The role of coronin 1 during cell mediated immune responses [PDF]

, 2013
Coronin 1 is one of 7 mammalian isoforms member of the evolutionary conserved WD40-repeat proteins that are involved in a variety of activities such a cell migration and cytokinesis.

Tumor‐Intrinsic ARHGEF3 Enhances Antitumor Immunity by Promoting T‐Cell Infiltration and Limiting Myeloid Cell‐Mediated Immunosuppression

Advanced Science, EarlyView.
ARHGEF3 is broadly downregulated across human cancers and correlates with patient prognosis. Tumor‐intrinsic ARHGEF3 activates the RHOA–ROCK–PTEN cascade to inhibit AKT signaling, thereby promoting chemokine‐driven T‐cell infiltration and relieving lipid‐mediated myeloid immunosuppression.

Vaccine-induced T cell receptor T cell therapy targeting a glioblastoma stemness antigen

Nature Communications
T cell receptor-engineered T cells (TCR-T) could be advantageous in glioblastoma by allowing safe and ubiquitous targeting of the glioblastoma-derived peptidome.

Optimization of B Cell Responses in Human Immune System Mice Through Organoid Based Screening

Advanced Science, EarlyView.
Human immune system (HIS) mice show limited B cell responses to immunization. Using HIS mouse spleen organoids, this study identifies cytokine combinations and innate immune signals that drive human B cell expansion, differentiation, and class‐switch. Applying these signals in vivo through temporal separation enables antigen‐specific IgG responses and ...

The T cell receptor sequence influences the likelihood of T cell memory formation

Cell Reports
Summary: The amino acid sequence of the T cell receptor (TCR) varies between T cells of an individual’s immune system. Particular TCR residues nearly guarantee mucosal-associated invariant T (MAIT) and natural killer T (NKT) cell transcriptional fates ...
