Syk-mediated translocation of PI3Kδ to the leading edge controls lamellipodium formation and migration of leukocytes [PDF]

open access: yes, 2007
The non-receptor tyrosine kinase Syk is mainly expressed in the hematopoietic system and plays an essential role in β2 integrin-mediated leukocyte activation.

Combined Antiplatelet Therapy Reduces the Proinflammatory Properties of Activated Platelets

open access: yesTH Open, 2021
The cause of atherothrombosis is rupture or erosion of atherosclerotic lesions, leading to an increased risk of myocardial infarction or stroke. Here, platelet activation plays a major role, leading to the release of bioactive molecules, for example ...

Optogenetic control of receptors reveals distinct roles for actin- and Cdc42-dependent negative signals in chemotactic signal processing

open access: yesNature Communications, 2021
Here the authors use optogenetic tools to directly measure spatial signal processing in leukocyte chemotaxis. Their results reveal the importance of multiple negative feedback loops for maintaining spatial information in chemotaxis.

CCR2 acts as scavenger for CCL2 during monocyte chemotaxis. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Leukocyte migration is essential for effective host defense against invading pathogens and during immune homeostasis. A hallmark of the regulation of this process is the presentation of chemokines in gradients stimulating leukocyte chemotaxis

Role of insulin hormone in modulation of inflammatory phenomena [PDF]

open access: yesEinstein (São Paulo), 2011
Evidence demonstrates the involvement of hormones in thedevelopment of inflammatory response. Inflammation evokes markedstructural alterations of microvasculature, besides migration ofleukocytes from microcirculation to the site of lesion.

Modeling leukocyte-leukocyte non-contact interactions in a lymph node. [PDF]

open access: yesPLoS ONE, 2013
The interaction among leukocytes is at the basis of the innate and adaptive immune-response and it is largely ascribed to direct cell-cell contacts. However, the exchange of a number of chemical stimuli (chemokines) allows also non-contact interaction ...

An Agent-Based Interpretation of Leukocyte Chemotaxis in Cancer-on-Chip Experiments

open access: yesMathematics, 2022
The present paper was inspired by recent developments in laboratory experiments within the framework of cancer-on-chip technology, an immune-oncology microfluidic chip aiming at studying the fundamental mechanisms of immunocompetent behavior. We focus on

Combined boyden-flow cytometry assay improves quantification and provides phenotypification of leukocyte chemotaxis. [PDF]

open access: yesPLoS ONE, 2011
Chemotaxis has been studied by classical methods that measure chemotactic and random motility responses in vitro, but these methods do not evaluate the total number and phenotype of migrating leukocytes simultaneously.

Monitoring Phosphoinositide Fluxes and Effectors During Leukocyte Chemotaxis and Phagocytosis

open access: yesFrontiers in Cell and Developmental Biology, 2021
The dynamic re-organization of cellular membranes in response to extracellular stimuli is fundamental to the cell physiology of myeloid and lymphoid cells of the immune system.
