TET2 regulates early and late transitions in exhausted CD8+ T-cell differentiation and limits CAR T-cell function

This study shows that targeting TET2 in CAR T-cells improves their anti-tumor responses by limiting terminal exhaustion and enhancing therapeutic potential.

In Vitro Modeling of CD8 T Cell Exhaustion Enables CRISPR Screening to Reveal a Role for BHLHE40

The paper establishes an in vitro model of CD8 T cell exhaustion and uses CRISPR screening to identify BHLHE40 as a regulator of T cell exhaustion differentiation.

The pseudokinase Trib1 regulates the transition of exhausted T cells to a KLR+ CD8+ effector state and its deletion improves checkpoint blockade

This study shows that deleting Trib1 shifts exhausted T cells to a KLR+ CD8+ effector state, enhancing viral clearance and checkpoint inhibitor response.

Prior vaccination enhances immune responses during SARS-CoV-2 breakthrough infection with early activation of memory T cells followed by production of potent neutralizing antibodies

Distinct Heterogeneity in the Naive T cell Compartments of Children and Adults

The study identifies age-related differences in naive T cell compartments between children and adults, showing distinct molecular reprogramming in CD4 and CD8 subsets.

Enhanced STAT5a activation rewires exhausted CD8 T cells during chronic stimulation to acquire a hybrid durable effector like state

This study shows that enhancing STAT5a activation in exhausted CD8 T cells rewires their epigenetic state to become a hybrid durable effector-like population with improved tumor control.

Longitudinal single cell transcriptional and epigenetic mapping of effector, memory, and exhausted CD8 T cells reveals shared biological circuits across distinct cell fates

This study maps transcriptional and epigenetic changes in CD8 T cell differentiation using scRNA-seq and scATAC-seq, revealing shared biological circuits across effector, memory, and exhausted cell fates.

Signaling through FcγRIIA and the C5a-C5aR pathway mediates platelet hyperactivation in COVID-19

This study identifies FcγRIIA and C5a-C5aR pathways as mediators of platelet hyperactivation in COVID-19 patients, showing their role in thrombotic complications.

Efficient recall of Omicron-reactive B cell memory after a third dose of SARS-CoV-2 mRNA vaccine

Divergent clonal differentiation trajectories of T cell exhaustion

This study identifies divergent clonal differentiation trajectories of T cell exhaustion during chronic viral infection, showing that TCR signal strength determines terminal or KLR Tex fates.

mRNA Vaccination Induces Durable Immune Memory to SARS-CoV-2 with Continued Evolution to Variants of Concern

This study shows that mRNA vaccination generates durable immune memory against SARS-CoV-2 and variants of concern, with continued evolution of B and T cell responses for at least 6 months.

Rapid induction of antigen-specific CD4+ T cells guides coordinated humoral and cellular immune responses to SARS-CoV-2 mRNA vaccination

This study shows that mRNA vaccination rapidly induces antigen-specific CD4+ T cells, which coordinate humoral and cellular immune responses, with booster doses enhancing T cell responses in naive individuals.

In vivo CRISPR screening identifies Fli1 as a transcriptional safeguard that restrains effector CD8 T cell differentiation during infection and cancer

The paper identifies Fli1 as a transcriptional regulator that limits effector CD8 T cell differentiation during infection and cancer, showing its deletion enhances TEFF responses and immunity.

Deep immune profiling of COVID-19 patients reveals patient heterogeneity and distinct immunotypes with implications for therapeutic interventions

The paper identifies distinct immunotypes in COVID-19 patients through high-dimensional cytometry, linking them to disease severity and potential therapeutic implications.

Chronic viral infection promotes early germinal center exit of B cells and impaired antibody development.

This study shows chronic viral infection disrupts GC B cell fate decisions, leading to early exit and impaired antibody development.
