Unlocking Hidden Potential: Exploring the Complexities of Signaling in Immune Cell Activation to Optimize CAR Therapy

Mathieu Girardin

Chimeric antigen receptors (CARs) are synthetic, transmembrane proteins that trigger immune cell signaling following their engagement. They have been first utilized in T cells and later in natural killer (NK) cells to redirect their cytotoxicity toward a s ...

Keap 1: The new Janus word on the block

Yimon Aye

Here we draw insights from the latest serendipitous findings made on the opposing roles of a proposed drug-target protein Keap1. We weigh up how natural reactive electrophiles and electrophilic small-molecule drugs in clinical use directly impinge on seemi ...

Dendritic cell cross-dressing and tumor immunity

Michele De Palma, Amaia Martinez Usatorre

In addition to direct and cross-presentation, dendritic cells (DCs) can present tumor antigens (TAs) to T cells via a hitherto poorly understood mechanism called "cross-dressing." DC cross-dressing involves the acquisition of preformed peptide-major histoc ...

Akt Is S-Palmitoylated: A New Layer of Regulation for Akt

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

The protein kinase Akt/PKB participates in a great variety of processes, including translation, cell proliferation and survival, as well as malignant transformation and viral infection. In the last few years, novel Akt posttranslational modifications have ...

The E protein-TCF1 axis controls gamma delta T cell development and effector fate

Freddy Radtke

TCF1 plays a critical role in T lineage commitment and the development of alpha beta lineage T cells, but its role in gamma delta T cell development remains poorly understood. Here, we reveal a regulatory axis where T cell receptor (TCR) signaling controls ...

Notch signaling promotes disease initiation and progression in murine chronic lymphocytic leukemia

Freddy Radtke, Ute Koch, Jessica Sordet, Nadine Fournier, Marianne Nkosi, Delphine Maude Tardivon, Mateusz Waldemar Antoszewski

NOTCH1 gain-of-function mutations are recurrent in B-cell chronic lymphocytic leukemia (B-CLL), where they are associated with accelerated disease progression and refractoriness to chemotherapy. The specific role of NOTCH1 in the development and progressio ...

C-reactive protein and white matter microstructural changes in COVID-19 patients with encephalopathy

Alessandra Griffa

Encephalopathy is a neurological complication of COVID-19. The objective of this exploratory study is to investigate the link between systemic inflammation and brain microstructural changes (measured by diffusion-weighted imaging) in patients with COVID-19 ...

Myeloid Cells Orchestrate Systemic Immunosuppression, Impairing the Efficacy of Immunotherapy against HPV+ Cancers

Douglas Hanahan, Nadine Fournier, Mélanie Louise Tichet, Melody Swartz, Stephan Wullschleger, Gabriele Galliverti

Cancers induced by human papillomaviruses (HPV) should be responsive to immunotherapy by virtue of expressing the immunogenic oncoproteins E6/E7. However, advanced forms of cervical cancer, driven by HPV, are poorly responsive to immune response-enhancing ...

Btk SH2-kinase interface is critical for allosteric kinase activation and its targeting inhibits B-cell neoplasms

Matteo Dal Peraro, Florence Pojer, Sandrine Madeleine Suzanne Georgeon, Maria Josefina Marcaida Lopez, Oliver Hantschel, Allan Joaquim Lamontanara, Tim Kükenshöner, Daniel Pereira Duarte, Grégory La Sala

Bruton's tyrosine kinase (Btk) is critical for B-cell maturation and activation. Btk loss-of-function mutations cause human X-linked agammaglobulinemia (XLA). In contrast, Btk signaling sustains growth of several B-cell neoplasms which may be treated with ...

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 ...

Targeting small molecule drugs to T cells with antibody-directed cell-penetrating gold nanoparticles

Francesco Stellacci, Ahmet Bekdemir, Ye Yang

We sought to develop a nanoparticle vehicle that could efficiently deliver small molecule drugs to target lymphocyte populations. The synthesized amphiphilic organic ligand-protected gold nanoparticles (amph-NPs) were capable of sequestering large payloads ...

Live imaging screen reveals that TYRO3 and GAK ensure accurate spindle positioning in human cells

Pierre Gönczy, Coralie Busso, Benita Wolf

Proper spindle positioning is crucial for spatial cell division control. Spindle positioning in human cells relies on a ternary complex comprising G alpha i1-3, LGN and NuMA, which anchors dynein at the cell cortex, thus enabling pulling forces to be exert ...

Targeted protein degradation through cytosolic delivery of monobody binders using bacterial toxins

Oliver Hantschel, Nadine Eliane Schmit, Katyayanee Neopane

Monobodies are small engineered binding proteins that, upon expression in cells, can inhibit signaling of cytosolic oncoproteins with outstanding selectivity. Efficacy may be further increased by inducing degradation of monobody targets through fusion to t ...

Selective Targeting of SH2 Domain–Phosphotyrosine Interactions of Src Family Tyrosine Kinases with Monobodies

Florence Pojer, Oliver Hantschel, Nadine Eliane Schmit, Tim Kükenshöner

The binding of Src-homology 2 (SH2) domains to phosphotyrosine (pY) sites is critical for the autoinhibition and substrate recognition of the eight Src family kinases (SFKs). The high sequence conservation of the 120 human SH2 domains poses a significant c ...

The corepressor NCOR1 regulates the survival of single-positive thymocytes

Johan Auwerx

Nuclear receptor corepressor 1 (NCOR1) is a transcriptional regulator bridging repressive chromatin modifying enzymes with transcription factors. NCOR1 regulates many biological processes, however its role in T cells is not known. Here we show that Cd4-Cre ...

New immunomodulatory roles of lymphatic endothelium and implications for immunotherapy

Efthymia Vokali

The lymphatic system serves a critical role in fluid homeostasis, lipid metabolism and immune surveillance. The growing appreciation of its implication in various diseases challenges the conventional view of lymphatics as a passive transport system. Tradit ...
