IL7R expression

These findings highlight the ability of these early PD-1+ TCF-1+ TOX+ stem-like CD8+ T cells to adapt their differentiation trajectory to either an acute or chronic viral infection. Most importantly, our study shows that the host is prepared a priori to deal with a potential chronic infection.

IL7R plays a critical role in shaping TME diversity across cancer types and holds promise as a relevant biomarker for predicting immunotherapy benefits.

Our findings underscore a significant causal relationship between immunophenotypes and endometrial cancer in bidirectional MR analyses. Notably, the CM CD4+%T immunophenotype emerged as potentially crucial in endometrial cancer development.

This study contributes to understanding the mechanisms of Imatinib resistance in CML, proposing IL6R and MYC as pivotal targets for therapeutic strategies. Moreover, the utilization of NIADS v2 enhances our capability to analyze apoptosis and drug responses, contributing to a deeper understanding of CML pathogenesis and treatment options.

Lusvertikimab-mediated in vitro ADCP levels significantly correlated with CD127 expression levels and the reduction of leukemia burden upon treatment of PDX animals in vivo. Altogether, through its dual mode of action and good safety profile, Lusvertikimab may represent a novel immunotherapy option for any CD127-positive ALL, particularly in combination with standard-of-care polychemotherapy.

When applied to HSPCs further induced to differentiate into T cells in an Artificial Thymic Organoid system, our gene editing strategy overcame the T cell developmental block observed in IL7R-SCID patients, while promoting full maturation of T cells with physiological and developmentally regulated IL7R expression. Finally, genotoxicity assessment of the CRISPR/Cas9 platform in HSPCs using biased and unbiased technologies confirmed the safety of the strategy, paving the way for a new, efficient, and safe therapeutic option for IL7R-SCID patients.

This information can provide real-time guidance to patients, families, and providers on expectations. Additionally, CD4+CD127+ cells in the starting material appear to be necessary to overcome high disease burden, suggesting the importance of optimized manufacturing to expand this favorable cell subset.

Our data demonstrate T-bet overexpression improves CD28-costimulated CAR T cell expansion but does little to augment long-term responses and diminishes features associated with capacity for self-renewal. In contrast, T-bet overexpression boosts the potency of 4-1BB-costimulated CAR T cells without impairing persistence, resulting in improved overall efficacy of 4-1BB-costimulated CAR T cell therapies.

In relapse/refractory (R/R) patients, standard of care treatments, including nelarabine, yield response rate of about 20-40% and responses are of short duration...For example, TTOs included Tofacitinib and Venetoclax (Tofa/Ven) in case of IL7R (CD127) expression or IL7R-pathway alterations (IL7RALT), 5-azacytidine and Venetoclax (Aza/Ven) in case of T-ALL/LL with epigenetic regulators alterations (DNMT3A, ASXL1, PHF6, TET2, PRC2, IDH1/2, SRSF2...) or Temsirolimus, Erwinase and Venetoclax (Tem/Erw/Ven) in case of PI3K signaling pathway alterations (PI3KALT)...Twenty-five patients received a TTO, including 14 Aza/Ven (56%), 8 Tofa/Ven (32%), 2 Tem/Erw/Ven (8%) and 1 Trametinib/Ven (4%)...A better knowledge of the oncogenetic landscape of T-ALL, and a close collaboration between clinicians and biologists, resulted in individualized treatment strategies. With a 3 months cumulative incidence of response of 70%, TTOs appear to be a promising approach in R/R T-ALL.

1x106 CAR T cells (figure 2). Conclusions These data suggest that LYL119, which combines c-Jun overexpression, NR4A3 KO, Epi-R protocol, and Stim-R technology, can limit exhaustion, maintain stem-like features, and has potential to provide effective and durable CAR T-cell antitumor activity in patients with ROR1+ solid tumors.

In agreement with these findings, the cytokine binding CD127 was increased in patients with durable response to ICI (p<0.05, Student’s t-test). In this pilot study using pre-treatment biopsies from independent melanoma cohorts, we report that CD127 is associated with a favorable response to immune-checkpoint therapy. A marker of immune-checkpoint therapy response could help improve care for melanoma patients by informing the provision of optimal therapies and minimizing side-effects.

Thus, TCF1CD4 T cells function as disease stem cells and promote chronicity and autonomy of autoimmune tissue inflammation. Remission-inducing therapies will require targeting stem-like CD4 T cells instead of only effector T cells.
