The Tea4-PP1 landmark promotes local growth by dual Cdc42 GEF recruitment and GAP exclusion. [PDF]

, 2014
Cell polarization relies on small GTPases, such as Cdc42, which can break symmetry through self-organizing principles, and landmarks that define the axis of polarity.

A Cdc42/RhoA regulatory circuit downstream of glycoprotein Ib guides transendothelial platelet biogenesis

Nature Communications, 2017
Blood platelets are produced by large bone marrow (BM) precursor cells, megakaryocytes (MKs), which extend cytoplasmic protrusions (proplatelets) into BM sinusoids.

Parallel Genome‐Wide CRISPR Screens Reveal SORL1 and ZFYVE19 as Sequential Host Determinants of Salmonella Infection

Advanced Science, EarlyView.
To distinguish how Salmonella invades cells vs how it survives long‐term, a parallel CRISPR screening platform is developed. This approach reveals the host proteins that the bacterium exploits at different stages of infection. The study identifies SORL1 as a novel host factor for invasion and demonstrates that blocking it with an antibody effectively ...

GPCRs in CAR‐T Cell Immunotherapy: Expanding the Target Landscape and Enhancing Therapeutic Efficacy

Advanced Science, EarlyView.
Chimeric antigen receptor T cell therapy faces dual challenges of target scarcity and an immunosuppressive microenvironment in solid tumors. This review highlights how G protein‐coupled receptors can serve as both novel targets to expand the therapeutic scope and functional modules to enhance CAR‐T cell efficacy.

Relation of CDC42, Th1, Th2, and Th17 cells with cognitive function decline in Alzheimer's disease

Annals of Clinical and Translational Neurology, 2022
Objective Cell division cycle 42 (CDC42) regulates neurite outgrowth, neurotransmitter, and T help (Th) cell‐mediated neuroinflammation, while its clinical implication in Alzheimer's disease (AD) is not clear.

Caveolin-1 Phosphorylation Is Essential for Axonal Growth of Human Neurons Derived From iPSCs. [PDF]

, 2019
Proper axonal growth and guidance is essential for neuron differentiation and development. Abnormal neuronal development due to genetic or epigenetic influences can contribute to neurological and mental disorders such as Down syndrome, Rett syndrome, and

Anosmin-1 modulates fibroblast growth factor receptor 1 signaling in human gonadotropin-releasing hormone olfactory neuroblasts through a heparan sulfate-dependent mechanism [PDF]

, 2004
Defects of either anosmin-1 or fibroblast growth factor receptor 1 (FGFR1) are known to underlie hereditary Kallmann's syndrome (KS), a human disorder of olfactory and gonadotropin-releasing hormone (GnRH) neuronal ontogeny.

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 ...

Early Radial Extracorporeal Shockwave Stimulation on Proximal Tibial Circular Osteotomy Site Enhanced Heterotopic Skin Wound Healing via Small Extracellular Vesicles

Advanced Science, EarlyView.
A schematic diagram of the mechanism where small extracellular vesicles mediate the enhancement of heterotopic wound healing by radial extracorporeal shockwave stimulation at a proximal tibial osteotomy site. ABSTRACT Wound healing represents a complex biological process necessitating innovative therapeutic approaches, particularly for chronic wounds ...

Monogenic deficiency in murine intestinal Cdc42 leads to mucosal inflammation that induces crypt dysplasia

Genes and Diseases
CDC42 controls intestinal epithelial (IEC) stem cell (IESC) division. How aberrant CDC42 initiates intestinal inflammation or neoplasia is unclear. We utilized models of inflammatory bowel diseases (IBD), colorectal cancer, aging, and IESC injury to ...
