Muscle-specific function of the centronuclear myopathy and Charcot-Marie-Tooth neuropathy-associated dynamin 2 is required for proper lipid metabolism, mitochondria, muscle fibers, neuromuscular junctions and peripheral nerves [PDF]
The ubiquitously expressed large GTPase Dynamin 2 (DNM2) plays a critical role in the regulation of intracellular membrane trafficking through its crucial function in membrane fission, particularly in endocytosis.

Ubiquitination in Control of EGF Receptor Endocytosis [PDF]
Growth factors and growth factor receptors comprise a signaling network regulating cell differentiation and growth. Tightly regulation of this network is important to avoid excessive signaling and cell growth, which may result in cancer.

This study employs sc‐RNA sequencing, genetics, and phenotyping to systematically map the cell‐type‐specific immune responses triggered by flg22. It reveals FLS2‐dependent transcriptional reprogramming in epidermal and mesophyll cells, and uncovers crosstalk between immune and hypoxia signaling pathways.

Toxoplasma and Plasmodium protein kinases: roles in invasion and host cell remodelling [PDF]
Some apicomplexan parasites have evolved distinct protein kinase families to modulate host cell structure and function. Toxoplasma gondii rhoptry protein kinases and pseudokinases are involved in virulence and modulation of host cell signalling.

Synaptic Vesicle Dynamics sans Dynamin [PDF]
The neuron-specific guanosine triphosphatase dynamin 1 has been hypothesized to be critically required for pinching off synaptic vesicles during endocytosis. In a recent publication in Science, Ferguson et al. describe a series of experiments demonstrating an unexpectedly selective requirement of dynamin 1 in synaptic vesicle endocytosis only during ...

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis
Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

Background Lymphotoxin β receptor (LTβR) is a member of tumor necrosis factor receptor (TNFR) superfamily which regulates the immune response. At the cellular level, upon ligand binding, the receptor activates the pro-inflammatory NF-κB and AP-1 pathways.

Endogenous CCL2 neutralization restricts HIV-1 replication in primary human macrophages by inhibiting viral DNA accumulation [PDF]
Macrophages are key targets of HIV-1 infection. We have previously described that the expressionof CC chemokine ligand 2 (CCL2) increases during monocyte differentiation to macrophages and it is furtherup-modulated by HIV-1 exposure.

Dynamin and receptor‐mediated endocytosis [PDF]
The internalization of receptor‐bound ligands involves concentration of cell surface receptors in specialized areas of the plasma membrane and subsequent formation of clathrin‐coated vesicles. The complex process of invagination, constriction and budding of clathrin‐coated vesicles employs the coordinated actions of several proteins.

Nanoscale Spatial Organization of ARC High‐ and Low‐Order Assemblies at Excitatory Synapses
ARC (Activity‐Regulated Cytoskeleton‐Associated protein) mediates synaptic plasticity by forming nanoscale assemblies in neurons. Using super‐resolution microscopy and time‐resolved anisotropy with targeted tagging, the study reveals low‐order ARC assemblies at synapses colocalizing with AMPARs, semi‐circular structures at endocytic zones, and 60–80 nm
