Dynamic remodeling of septin structures fine-tunes myogenic differentiation

iScience
Summary: Controlled myogenic differentiation is integral to the development, maintenance and repair of skeletal muscle, necessitating precise regulation of myogenic progenitors and resident stem cells.

Centrosomal Actin Assembly Is Required for Proper Mitotic Spindle Formation and Chromosome Congression

iScience, 2019
Summary: Cytoskeletal cross talk between actin filaments and microtubules is a common mechanism governing the assembly of cellular structures, i.e., during filopodia formation or cilia organization.

Anticipating the species jump: surveillance for emerging viral threats. [PDF]

, 2012
Zoonotic disease surveillance is typically triggered after animal pathogens have already infected humans. Are there ways to identify high-risk viruses before they emerge in humans? If so, then how and where can identifications be made and by what methods?

ARAP1 Bridges Actin Dynamics and AP-3-Dependent Membrane Traffic in Bone-Digesting Osteoclasts

iScience, 2018
Summary: Bone-resorbing osteoclasts play a central role in bone remodeling and its pathology. To digest bone, osteoclasts re-organize both F-actin, to assemble podosomes/sealing zones, and membrane traffic, to form bone-facing ruffled borders enriched in

Modeling and simulating hierarchies using an agent-based approach [PDF]

, 2005
The notion of complex system covers many different meanings. Socio-economical and ecological systems are typically kind of 'organized complex systems', defined as a middle number of heterogeneous components interacting in an intricate manner and ...

A crosstalk between adhesion and phagocytosis integrates macrophage functions into their microenvironment

iScience
Summary: Phagocytosis is the process of actin-dependent internalization and degradation of large particles. Macrophages, which are professional phagocytes, are present in all tissues and are, thus, exposed to environments with different mechanical ...

Spatial transcriptomic analysis identifies epithelium-macrophage crosstalk in endometriotic lesions

iScience
Summary: The mechanisms underlying the pathophysiology of endometriosis, characterized by the presence of endometrium-like tissue outside the uterus, remain poorly understood.

Calumenin-1 Interacts with Climp63 to Cooperatively Determine the Luminal Width and Distribution of Endoplasmic Reticulum Sheets

iScience, 2019
Summary: The ER is composed of distinct structures like tubules, matrices, and sheets, all of which are important for its various functions. However, how these distinct ER structures, especially the perinuclear ER sheets, are formed remains unclear.

Magnetism, FeS colloids, and Origins of Life

, 2010
A number of features of living systems: reversible interactions and weak bonds underlying motor-dynamics; gel-sol transitions; cellular connected fractal organization; asymmetry in interactions and organization; quantum coherent phenomena; to name some ...

Ultrastructural aspects of ecdysis in the naked dinoflagellate Amphidinium carterae

Protistology, 2019
The stressor-induced ecdysis takes a special place in dinoflagellate biology. During ecdysis, a cell loses the plasmalemma, outer amphiesmal vesicle membrane and, in armored species, thecal plates, becomes immotile, and then amphiesma regeneration occurs.
