Dendritic Cell Migration: An Essential Step in Initiating Adaptive Immunity Across Tissues

open access: yesImmunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Immune surveillance of tissues is primarily carried out by dendritic cells (DCs), which act as sentinels for the adaptive immune system. To accomplish this task, DCs migrate from tissues to regional lymph nodes, or from blood‐exposed regions of the spleen to the white pulp, to prime T cell responses. DC migration is a tightly regulated process

Atypical protein kinase C (PKCzeta/lambda) is a convergent downstream target of the insulin-stimulated phosphatidylinositol 3-kinase and TC10 signaling pathways. [PDF]

open access: yes, 2004
Insulin stimulation of adipocytes resulted in the recruitment of atypical PKC (PKCzeta/lambda) to plasma membrane lipid raft microdomains. This redistribution of PKCzeta/lambda was prevented by Clostridium difficile toxin B and by cholesterol depletion ...

Rho GTPases show differential sensitivity to nucleotide triphosphate depletion in a model of ischemic cell injury [PDF]

open access: yes, 2003
Rho GTPases are critical for actin cytoskeletal regulation, and alterations in their activity may contribute to altered cytoskeletal organization that characterizes many pathological conditions, including ischemia. G protein activity is a function of the

Regulator of G‐Protein Signalling Protein AaRgs2 Negatively Regulates Appressorium‐Like Formation of Alternaria alternata Induced by Pear Cutin Monomer via the AaRgs2‐AaGα1‐AaAC Module

open access: yesMolecular Plant Pathology, Volume 27, Issue 1, January 2026.
AaRgs2 negatively regulates appressorium‐like formation of A. alternata induced by pear cutin monomer via the AaRgs2‐AaGα1‐AaAC module. ABSTRACT Pathogenic fungi have developed complex and specific infection strategies to invade host tissues successfully.

Characterization of ROP GTPase-activated Arabidopsis receptor-like cytoplasmic kinases (RLCK class VI_A) [PDF]

open access: yes, 2011
Plants have to respond and adapt to a variety of continuously changing environmental factors in order to establish an appropriate developmental strategy to ensure survival. There are ample data showing that protein phosphorylation/dephosphorylation plays

Development of a fluorogenic sensor for activated Cdc42 [PDF]

open access: yes, 2011
Cdc42, a member of the Rho GTPase family, is a fundamental regulator of the actin cytoskeleton during cell migration. To generate a sensor for Cdc42 activation, we employed a multi-pronged approach, utilizing cysteine labeling and expressed protein ...

CDC42 and Rac1 control different actin-dependent processes in the Drosophila wing disc epithelium. [PDF]

open access: yes, 1995
Cdc42 and Rac1 are members of the rho family of small guanosinetriphosphatases and are required for a diverse set of cytoskeleton-membrane interactions in different cell types.

A Rho family GTPase controls actin dynamics and tip growth via two counteracting downstream pathways in pollen tubes. [PDF]

open access: yes, 2005
Tip growth in neuronal cells, plant cells, and fungal hyphae is known to require tip-localized Rho GTPase, calcium, and filamentous actin (F-actin), but how they interact with each other is unclear.

Mechanical Signaling: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

open access: yesMedComm, Volume 6, Issue 12, December 2025.
In this review, we summarize cell–ECM interactions and delve into the complex mechanotransduction. We introduce advanced research methods and emerging clinical tools used to study cellular mechanical phenotypes, mechanotransduction, and disease progression. Additionally, we analyze the role of mechanical biomarkers in the development and progression of
