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

PLoS 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.

Denervated Schwann cells attract macrophages by secretion of leukemia inhibitory factor (LIF) and monocyte chemoattractant protein-1 in a process regulated by interleukin-6 and LIF [PDF]

, 2002
Injury to peripheral nerves results in the infiltration of immune cells, which remove axonal- and myelin-derived material. Schwann cells could play a key role in this process by regulating macrophage infiltration.

Monitoring Phosphoinositide Fluxes and Effectors During Leukocyte Chemotaxis and Phagocytosis

Frontiers 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.

A randomized double blinded placebo controlled clinical trial for the evaluation of green coffee extract on immune health in healthy adults

Journal of Traditional and Complementary Medicine, 2022
Background: The immune system functions to protect the host from a broad array of infectious diseases. Here, we evaluated the in vitro immunomodulatory effects of green coffee extract (GCE), and conducted a double-blinded, randomized and placebo ...

Preinfection in vitro chemotaxis, phagocytosis, oxidative burst, and expression of CD11/CD18 receptors and their predictive capacity on the outcome of mastitis induced in dairy cows with Escherichia coli. [PDF]

, 1997
Four to 6 wk after parturition, 12 cows in second, fourth, or fifth lactation were experimentally infected in one gland with Escherichia coli. The capacity of chemotaxis, phagocytosis, oxidative burst, and expression of CD11/CD18 receptors to predict the

Focal MMP-2 and MMP-9 Activity at the Blood-Brain Barrier Promotes Chemokine-Induced Leukocyte Migration

Cell Reports, 2015
Although chemokines are sufficient for chemotaxis of various cells, increasing evidence exists for their fine-tuning by selective proteolytic processing. Using a model of immune cell chemotaxis into the CNS (experimental autoimmune encephalomyelitis [EAE]

Skap2 is required for β2 integrin-mediated neutrophil recruitment and functions. [PDF]

, 2017
Integrin activation is required for neutrophil functions. Impaired integrin activation on neutrophils is the hallmark of leukocyte adhesion deficiency (LAD) syndrome in humans, characterized by impaired leukocyte recruitment and recurrent infections. The

Psoriasis and Leukocyte Chemotaxis.

Journal of Investigative Dermatology, 1987
Transepidermal migration of leukocytes, with resultant formation of microscopic or macroscopic sterile subcorneal pustules is a phenomenon characteristically noted in psoriasis and related sterile pustular dermatoses. It is natural to assume the presence of potent neutrophil chemotactic substances in the subcorneal portion of the lesional epidermis ...

Neutrophil swarms require LTB4 and integrins at sites of cell death in vivo [PDF]

, 2013
Neutrophil recruitment from blood to extravascular sites of sterile or infectious tissue damage is a hallmark of early innate immune responses, and the molecular events leading to cell exit from the bloodstream have been well defined1,2. Once outside the

Identification and validation of candidate genes dysregulated in alveolar macrophages of acute respiratory distress syndrome [PDF]

PeerJ, 2021
Background Acute respiratory distress syndrome (ARDS) is a common cause of death in ICU patients and its underlying mechanism remains unclear, which leads to its high mortality rate. This study aimed to identify candidate genes potentially implicating in
