Summary: Rabies virus infects N2a cells in a manner dependent on microtubule integrity as well as the function of dynein and kinesin. Microtubule-depolymerizing drugs, dynein inhibitors, and disruption of kinesin function can all hinder Rabies virus infection.

Summary: The study demonstrates an antagonistic mechanical balance within the dynein-kinesin microtubular motor system, where dynein activity drives inward compaction of the microtubular network, while kinesins bundle and expand MTs into giant circular bands. This balance controls the 3D architecture, mechanics, and cell-microenvironment interactions of cells through orthogonal mechanisms of MT network reorganization.

Summary: Microtubules are essential for various cellular functions and mutations in tubulin genes can lead to a range of diseases collectively known as tubulinopathies. Recent studies have shown that these mutations also affect microtubule-associated proteins (MAPs), which play important roles in microtubule regulation. In this review, we analyze the disease mechanisms caused by tubulin mutations on MAP binding and discuss how genetic variation can be utilized to identify novel MAPs.

Summary: Cells are the smallest building blocks of living organisms, and often undergo cytoplasmic streaming to compensate for physical constraints in large cells. This phenomenon is driven by molecular motors and plays important roles in various cell types. Additionally, intercellular flow transports cytoplasmic materials for rapid oocyte growth.

Summary: In this review, the authors explore the regulation of intraflagellar transport (IFT) in cilia from three different perspectives: the motor track, motor proteins, and kinases. By discussing these factors, the authors provide mechanistic insights into IFT regulation in cilia and suggest directions for future research.

Summary: Neuronal migration is a crucial process in brain development. Nesprin-2, a nuclear membrane protein, acts as an adapter to facilitate the movement of neuronal nucleus along microtubule tracks. Recent evidence suggests that Nesprin-2 plays a pivotal role in mediating bidirectional neuronal nuclear movements.

Summary: This study reports that microtubules can physically couple motor movement in the absence of detectable short-range interactions. The long-range microtubule-mediated coupling mechanism may affect the binding kinetics and mechanochemistry of motors, providing new forms of collective motor behavior.

Summary: Peroxisomes are essential organelles involved in metabolic processes, requiring both long- and short-range trafficking for optimal positioning in cells. This review examines the mechanisms of peroxisomal distribution, with a focus on regulatory overlaps between mitochondrial and peroxisomal trafficking, as well as the role of mitochondrial Rho-GTPase Miro in peroxisomal dynamics. Additionally, it discusses pathological and pharmacological conditions affecting peroxisomal positioning, along with highlighting gaps in current knowledge and suggesting future research directions.

Summary: Tight junctions play a crucial role in maintaining the integrity and permeability of the intestinal epithelial barrier. Disruption of tight junction formation or integrity can lead to various gastrointestinal diseases. The mechanism of intracellular transport of tight junction proteins remains unclear and requires further study.

Summary: Active matter systems generate ordered structures and avoid equilibrium through energy consumption. However, the translation of microscopic parameters to observed mesoscopic properties remains unclear. Investigating the motor-microtubule interactions, this research explores the impact of these interactions on coherent structures. The findings provide insights into the influence of microscopic motor properties on collective motor-microtubule assemblies.

Summary: Cell migration requires various proteins that interact with the cytoskeleton. Sperm flagella protein-1 (Spef1) is a multifunctional protein that interacts with cytoskeletal structures. It plays important roles in flagellar and ciliary motility, microtubule binding and stability, regulation of cell polarity, and maintenance of actin-based structures during cell migration.
