Host Defense Peptide LL-37-Mediated Chemoattractant Properties, but Not Anti-Inflammatory Cytokine IL-1RA Production, Is Selectively Controlled by Cdc42 Rho GTPase via G Protein-Coupled Receptors and JNK Mitogen-Activated Protein Kinase

Frontiers in Immunology, 2018
The human host defense peptide LL-37 promotes immune activation such as induction of chemokine production and recruitment of leukocytes. Conversely, LL-37 also mediates anti-inflammatory responses such as production of anti-inflammatory cytokines, e.g ...

Many-body effects in tracer particle diffusion with applications for single-protein dynamics on DNA [PDF]

, 2015
30% of the DNA in E. coli bacteria is covered by proteins. Such high degree of crowding affect the dynamics of generic biological processes (e.g. gene regulation, DNA repair, protein diffusion etc.) in ways that are not yet fully understood. In this paper, we theoretically address the diffusion constant of a tracer particle in a one dimensional system ...

Analysis of Rho GTPase signalling pathways regulating epithelial morphogenesis [PDF]

, 2010
Rho GTPases are molecular switches controlling many aspects of cell behaviour, including cell cycle progression, cell division, migration and morphology. The activity of Rho proteins is regulated by conformational changes induced by binding of guanine

Dynamic Plasma Membrane Topography Linked With Arp2/3 Actin Network Induction During Cell Shape Change

BioEssays, EarlyView.
Cell shape changes underlie animal development, physiology, and disease. The cell surface is mechanosensitive to the microenvironment and cytoskeleton activities, which generate plasma membrane topographies recognized and affected by Arp2/3 actin network induction pathways to remodel cell shape during immune cell migration, neural progenitor cell ...

Distinct CED-10/Rac1 domains confer context-specific functions in development. [PDF]

PLoS Genetics, 2018
Rac GTPases act as master switches to coordinate multiple interweaved signaling pathways. A major function for Rac GTPases is to control neurite development by influencing downstream effector molecules and pathways.

Effects of decreased Rac activity and malignant state on oral squamous cell carcinoma in vitro.

PLoS ONE, 2021
Rac proteins, members of the Rho family of small GTP-binding proteins, have been implicated in transducing a number of signals for various biological mechanisms, including cell cytoskeleton organization, transcription, proliferation, migration, and ...

Interaction of G protein Gβγ dimers with small GTP‐binding proteins of the Rho family

FEBS Letters, 1996
Gβγ dimers of heterotrimeric G proteins have been shown to be important for the translocation of cytosolic proteins to membranes. The involvement of Gβγ in those signaling processes mediated by small GTP‐binding proteins of the Rho family was studied using purified proteins.

Regulation of polarised growth in fungi [PDF]

, 2008
Polarised growth in fungi occurs through the delivery of secretory vesicles along tracks formed by cytoskeletal elements to specific sites on the cell surface where they dock with a multiprotein structure called the exocyst before fusing with the ...

A Proteomics Profiling Reveals the Neuroprotective Effects of Melatonin on Exogenous β‐amyloid‐42 Induced Mitochondrial Impairment, Intracellular β‐amyloid Accumulation and Tau Hyperphosphorylation in Human SH‐SY5Y Cells

Cell Biology International, EarlyView.
ABSTRACT Alzheimer's disease (AD) is prevalent in the elderly population and characterized by the intracellular accumulation of neurofibrillary tangles (NFTs), composed of tau proteins, and extracellular deposition of beta‐amyloid protein (Aβ). The present study aimed to investigate the neuroprotective effects of melatonin on Aβ42‐induced AD‐like ...
