Exploring the role of cGAS-STING-mediated inflammation in age-associated neurodegeneration and antitumor immunity

Natasha Ella Samson

Inflammation stands as a dynamic and intricate biological process, promoting vital defence mechanisms against harmful stimuli, including infections and injuries, to drive pathogen clearance and healing. On one hand, these responses can manifest acutely and ...

Countering T cell exhaustion and senescence for enhanced adoptive T cell therapies against solid tumors

Yang Zhao

CAR-T cell therapy has shown remarkable success in treating hematopoietic malignancies, but its efficacy in solid tumors is limited by T cell dysfunction, including exhaustion and senescence. In this study, we designed metabolically armored CAR-T cells to ...

Disruption of stem cell niche-confined R-spondin 3 expression leads to impaired hematopoiesis

Freddy Radtke, Ute Koch

Self-renewal and differentiation of stem and progenitor cells are tightly regulated to ensure tissue homeostasis. This regulation is enabled both remotely by systemic circulating cues, such as cytokines and hormones, and locally by various niche-confined f ...

Resistance mechanism to Notch inhibition and combination therapy in human T cell acute lymphoblastic leukemia

Linlin Cao

T cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological malignancy caused by acquisition of genetic alterations during T-cell development. The 5-year overall survival of pediatric T-ALL patients has improved considerably over the past 30 ...

Notch1-driven T-ALL chromatin landscape is regulated by Tcf1 in hematopoietic progenitors

Mateusz Waldemar Antoszewski

Notch1 receptor signaling is essential for T cell fate specification and physiological thymic T lymphocyte development. Its dysregulation and oncogenic activation are detected in almost 80% of pediatric patients suffering from T cell acute lymphoblastic le ...

Notch Signaling - a Booster of Chronic Lymphocytic Leukemia During Initiation and Disease Progression

Delphine Maude Tardivon

Chronic lymphocytic leukemia (CLL) is a B cell malignancy and represents the most common leukemia in adults within the Western world. This disease mainly affects the elderly, with a median age of diagnosis over 70. The disease course is highly variable amo ...

Targeting the oncogenic signaling of the transcription factor STAT3 with potent and selective monobody inhibitors

Grégory La Sala

Many targeted cancer therapies fail to improve the overall survival of patients. Limitations involve low drug selectivity and the rapid development of resistance. Moreover, the majority of oncogenic drivers presently remain considered as undruggable as th ...

Sirt6 deletion in bone marrow-derived cells increases atherosclerosis - Central role of macrophage scavenger receptor 1

Johan Auwerx

Aims: Sirtuin 6 (Sirt6) is a NAD(+)-dependent deacetylase that plays a key role in DNA repair, inflammation and lipid regulation. Sirt6-null mice show severe metabolic defects and accelerated aging. Macrophage-foam cell formation via scavenger receptors is ...

The Periostin/Integrin-alpha v Axis Regulates the Size of Hematopoietic Stem Cell Pool in the Fetal Liver

Jörg Hülsken

We earlier showed that outside-in integrin signaling through POSTN-ITGAV interaction plays an important role in regulating adult he-matopoietic stem cell (HSC) quiescence. Here, we show that Itgav deletion results in increased frequency of phenotypic HSCs ...

Allosteric regulation and targeting of Bruton's tyrosine kinase (Btk) in B-cell lymphoma

Daniel Pereira Duarte

Bruton's tyrosine kinase (Btk) is a key component of BCR signaling required for B-cell maturation and activation. Loss-of-function mutations throughout the Btk protein cause human X-linked agammaglobulinemia (XLA), a heritable genetic disorder characterize ...
