Platelet SHARPIN regulates platelet adhesion and inflammatory responses through associations with αIIbβ3 and LUBAC by Ana Kasirer-Friede et al.
Platelets form hemostatic plugs to prevent blood loss, and they modulate immunity and inflammation in several ways. A key event during hemostasis is activation of…

Cargo-specific recruitment in clathrin- and dynamin-independent endocytosis by Paulina Moreno-Layseca et al.
Spatially controlled, cargo-specific endocytosis is essential for development, tissue homeostasis and cancer invasion. Unlike cargo-specific clathrin-mediated endocytosis, the clathrin- and dynamin-independent endocytic pathway (CLIC-GEEC, CG…

SHANK3 conformation regulates direct actin binding and crosstalk with Rap1 signaling by Siiri I Salomaa et al.
Actin-rich cellular protrusions direct versatile biological processes from cancer cell invasion to dendritic spine development. The stability, morphology, and specific biological functions of these protrusions…

Sortilin-related receptor is a druggable therapeutic target in breast cancer by Hussein Al-Akhrass et al.
In breast cancer, the currently approved anti-receptor tyrosine-protein kinase erbB-2 (HER2) therapies do not fully meet the expected clinical goals due to therapy resistance. Identifying…

Myosin-X and talin modulate integrin activity at filopodia tips by Mitro Miihkinen et al.
Filopodia assemble unique integrin-adhesion complexes to sense the extracellular matrix. However, the mechanisms of integrin regulation in filopodia are poorly defined. Here, we report that…

Zebrafish Embryo Xenograft and Metastasis Assay by Ilkka Paatero et al.
Xenograft models, and in particular the mouse xenograft model, where human cancer cells are transplanted into immunocompromised mice, have been used extensively in cancer studies.…

Talin rod domain-containing protein 1 (TLNRD1) is a novel actin-bundling protein which promotes filopodia formation by Alana R Cowell et al.
Talin is a mechanosensitive adapter protein that couples integrins to the cytoskeleton. Talin rod domain-containing protein 1 (TLNRD1) shares 22% homology with the talin R7R8…
-
Integrin adhesion complexes by Megan R Chastney et al.
Tissue architecture and function are orchestrated by an intricate repertoire of cellular adhesion and signalling receptors, and by the surrounding extracellular matrix (ECM). The essential…

Food for thought: How cell adhesion coordinates nutrient sensing by Hellyeh Hamidi et al.
Cell adhesion controls cell survival and proliferation via multiple mechanisms. Rabanal-Ruiz et al. (2021. J. Cell Biol.https://doi.org/10.1083/jcb.202004010) demonstrate that focal adhesions are key signaling hubs…

A feed-forward loop between SorLA and HER3 determines heregulin response and neratinib resistance by Hussein Al-Akhrass et al.
Current evidence indicates that resistance to the tyrosine kinase-type cell surface receptor (HER2)-targeted therapies is frequently associated with HER3 and active signaling via HER2-HER3 dimers,…

Kinase-Independent Functions of MASTL in Cancer: A New Perspective on MASTL Targeting by James Ronald William Conway et al.
Microtubule-associated serine/threonine kinase-like (MASTL; Greatwall) is a well-characterized kinase, whose catalytic role has been extensively studied in relation to cell-cycle acceleration. Importantly, MASTL has been…
-
Mechano-responsiveness of fibrillar adhesions on stiffness-gradient gels by Nuria Barber-Pérez et al.
Fibrillar adhesions are important structural and adhesive components in fibroblasts, and are required for fibronectin fibrillogenesis. While nascent and focal adhesions are known to respond…

MASTL promotes cell contractility and motility through kinase-independent signaling by Maria Emilia Taskinen et al.
Microtubule-associated serine/threonine-protein kinase-like (MASTL) is a mitosis-accelerating kinase with emerging roles in cancer progression. However, possible cell cycle-independent mechanisms behind its oncogenicity remain ambiguous. Here,…

Fluctuation-Based Super-Resolution Traction Force Microscopy by Aki Stubb et al.
Cellular mechanics play a crucial role in tissue homeostasis and are often misregulated in disease. Traction force microscopy is one of the key methods that…

Integrin Binding Dynamics Modulate Ligand-Specific Mechanosensing in Mammary Gland Fibroblasts by Martina Lerche et al.
The link between integrin activity regulation and cellular mechanosensing of tissue rigidity, especially on different extracellular matrix ligands, remains poorly understood. Here, we find that…

Superresolution architecture of cornerstone focal adhesions in human pluripotent stem cells by Aki Stubb et al.
While it is clear that key transcriptional programmes are important for maintaining pluripotency, the requirement for cell adhesion to the extracellular matrix remains poorly defined.…
-
Filopodia Quantification Using FiloQuant by Guillaume Jacquemet et al.
Filopodia are fingerlike membrane protrusions that are extended by cells in vitro and in vivo. Due to important roles in sensing the extracellular microenvironment, filopodia…

A Negative Feedback Loop Regulates Integrin Inactivation and Promotes Neutrophil Recruitment to Inflammatory Sites by Barry McCormick et al.
Neutrophils are abundant circulating leukocytes that are rapidly recruited to sites of inflammation in an integrin-dependent fashion. Contrasting with the well-characterized regulation of integrin activation,…

Transcytosis route mediates rapid delivery of intact antibodies to draining lymph nodes by Laura Kähäri et al.
Lymph nodes (LNs) filter lymph to mount effective immune responses. Small soluble lymph-borne molecules from the periphery enter the draining LNs via a reticular conduit…
