Selective neutrophil desensitization to chemotactic factors. [PDF]

open access: yesThe Journal of cell biology, 1979
In the presence of extracellular calcium and magnesium, a series of chemotactic oligopeptides and C5a caused aggregation of human polymorphonuclear neutrophils (PMNs). This cellular response developed rapidly and began to reverse 2 min after exposure to the chemotactin.

An optimization of hematopoietic stem and progenitor cell isolation for scientific and clinical purposes by the application of a new parameter determining the hematopoietic graft efficacy.

open access: yesFolia Histochemica et Cytobiologica, 2008
The transplantation of hematopoietic stem and progenitor cells (HSPC) is an established lifesaving therapy. Bone marrow (BM), harvested from heparinized cadaveric organ donors, peripheral blood (PB) and cord blood (CB), are important sources of ...

Mechanistic modeling of light-induced chemotactic infiltration of bacteria into leaf stomata.

open access: yesPLoS Computational Biology, 2020
Light is one of the factors that can play a role in bacterial infiltration into leafy greens by keeping stomata open and providing photosynthetic products for microorganisms.

Chemotactic Deactivation of Human Eosinophils by the Eosinophil Chemotactic Factor of Anaphylaxis

open access: yesExperimental Biology and Medicine, 1975
Purified human eosinophils demonstrate diminished chemotactic responsiveness (deactivation) after incubation with the eosinophil chemotactic factor of anaphylaxis (ECF-A). The deactivation is rapid and selective in that ECF-A deactivated human eosinophils more markedly than neutrophilic or mononuclear leukocytes.

Derivatives of Differentiation-Inducing Factor 1 Differentially Control Chemotaxis and Stalk Cell Differentiation in Dictyostelium discoideum

open access: yesBiology, 2023
Differentiation-inducing factors 1 and 2 (DIF-1 and DIF-2) are small lipophilic signal molecules that induce stalk cell differentiation but differentially modulate chemotaxis toward cAMP in the cellular slime mold Dictyostelium discoideum; DIF-1 ...

Increased migratory activity and cartilage regeneration by superficial-zone chondrocytes in enzymatically treated cartilage explants

open access: yesBMC Musculoskeletal Disorders, 2022
Background Limited chondrocyte migration and impaired cartilage-to-cartilage healing is a barrier in cartilage regenerative therapy. Collagenase treatment and delivery of a chemotactic agent may play a positive role in chondrocyte repopulation at the ...

Neutrophil deficiency increases T cell numbers at the site of tissue injury in mice

open access: yesFEBS Letters, EarlyView.
In wild‐type mice, injury or acute inflammation induces neutrophil influx followed by macrophage accumulation. Mcl1ΔMyelo (neutrophil‐deficient) mice lack neutrophils, and in response to muscle injury show fewer macrophages and exhibit strikingly elevated T‐cell numbers, primarily non‐conventional “double‐negative” (DN) αβ and γδ T cells.

Galectin-9-like from Angiostrongylus cantonensis young adult worms modulates eosinophil chemotaxis in vitro

open access: yesJournal of Microbiology, Immunology and Infection, 2020
Background/purpose: Eosinophils are recruited to the brain of mice after infection with Angiostrongylus canonensis. Several factors produced by infected mice are well known playing the role to chemoattract eosinophils from the blood into the brain.

Inter-Relationship between Chemokines and Mast Cells

open access: yesEuropean Journal of Inflammation, 2010
The inflammatory response is mediated by immunological and chemotactic factors, proteins of the complement system, histamine, serotonin, arachidonic acid products and cytokines.

The role of selected chemokines and their receptors in the pathogenesis and destabilisation of atheromatous plaques in the carotid arteries

open access: yesAktualności Neurologiczne, 2015
Chemokines are cytokines that act selectively on cells and are capable of inducing selective migration of cells in vitro and in vivo. The term was first coined at the 3rd International Symposium on Chemotactic Cytokines in 1992. The name “chemokine” is
