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

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 ...

Post-translational regulation of neuronal differentiation

Jaipreet Singh Loomba

Glycosphingolipids (GSLs) are amphipathic lipid moieties that make up only 3% of the total lipid content of the cell and are almost exclusively expressed at the Plasma Membrane(PM). They are key drivers of signalling hotspots known as âlipid-raftsâ as ...

Structural basis for recognition of RALF peptides by LRX proteins during pollen tube growth

Sarah Wehrle

Plant reproduction relies on the highly regulated growth of the pollen tube for sperm delivery. This process is controlled by secreted RALF signaling peptides, which have previously been shown to be perceived by Catharanthus roseus RLK1-like (CrRLK1Ls) mem ...

Transmembrane Prolines Mediate Signal Sensing and Decoding in Bacillus subtilis DesK Histidine Kinase

Matteo Dal Peraro, Luciano Andres Abriata

Environmental awareness is an essential attribute of all organisms. The homeoviscous adaptation system of Bacillus subtilis provides a powerful experimental model for the investigation of stimulus detection and signaling mechanisms at the molecular level. ...

Cell culture-based biosensing techniques for detecting toxicity in water

The significant increase of contaminants entering fresh water bodies calls for the development of rapid and reliable methods to monitor the aquatic environment and to detect water toxicity. Cell culture-based biosensing techniques utilise the overall cytot ...

Effect of N-Terminal Myristoylation on the Active Conformation of Gα

Ursula Röthlisberger, Siri Camee van Keulen

G proteins are part of the G-protein-coupled receptor (GPCR) signal transduction cascade in which they transfer a signal from the membrane-embedded GPCR to other proteins in the cell. In the case of the inhibitory G-protein heterotrimer, permanent N-termin ...

Differential signaling networks of Bcr-Abl p210 and p190 kinases in leukemia cells defined by functional proteomics

Romain Hamelin, Sandrine Madeleine Suzanne Georgeon, Oliver Hantschel, Sina Maren Reckel

The two major isoforms of the oncogenic Bcr-Abl tyrosine kinase, p210 and p190, are expressed upon the Philadelphia chromosome translocation. p210 is the hallmark of chronic myelogenous leukemia, whereas p190 occurs in the majority of B-cell acute lymphobl ...

Functional Perturbation of the Gab2 Multiprotein Complex by High-affinity SH2-binding Monobodies in Chronic Myelogenous Leukemia

Emel Basak Gencer Akçok

Chronic myeloid leukemia is characterized by a reciprocal chromosomal translocation between chromosome 9 and 22, resulting in the expression of the Bcr-Abl oncoprotein. Despite the great improvement in patient survival using tyrosine kinase inhibitors (TKI ...

3D niche microarrays for systems-level analyses of cell fate

Matthias Lütolf, Adrian Ranga, Samy Gobaa, Katarzyna Mosiewicz, Andrea Negro, Yuya Okawa

The behaviour of mammalian cells in a tissue is governed by the three-dimensional (3D) microenvironment and involves a dynamic interplay between biochemical and mechanical signals provided by the extracellular matrix (ECM), cell–cell interactions and solub ...

A Parkinson's disease gene regulatory network identifies the signaling protein RGS2 as a modulator of LRRK2 activity and neuronal toxicity

Patrick Aebischer, Bernard Schneider, Liliane Glauser, Darren Moore, Klodjan Stafa, Julien Dusonchet

Mutations in LRRK2 are one of the primary genetic causes of Parkinson's disease (PD). LRRK2 contains a kinase and a GTPase domain, and familial PD mutations affect both enzymatic activities. However, the signaling mechanisms regulating LRRK2 and the pathog ...
