A Role for the Laminin Receptor in Leukocyte Chemotaxis

open access: yesJournal of Leukocyte Biology, 1987
Abstract Previous studies on the mechanism of leukocyte traversal of basement membranes showed that rabbit peritoneal exudate polymorphonuclear cells (PMN) preferentially used laminin, a major constituent of basement membrane, to attach to another component, type IV collagen.

Assays of Leukocyte Chemotaxis

Annual Review of Medicine, 1986
A number of disorders of leukocyte motility and chemotaxis have been reported clinically. In this paper we present a rational approach for testing cell populations for a defect in leukocyte migration and for defining the cellular basis of any abnormality observed. The principles and difficulties of individual and population-type assays are discussed.

Disorders of Leukocyte Chemotaxis

Pediatric Clinics of North America, 1977
The rapid accumulation of inflammatory cells at sites of microbial invasion or neoplastic transformation is a central event in immunologically-mediated host defense. The availability of methodology to accurately quantify leukocyte migration in vitro has allowed the disclosure of previously unrecognized clinical disorders, namely leukocyte dysmotility ...

Leukocyte Chemotaxis and Pyoderma Gangrenosum

International Journal of Dermatology, 1985
Abstract: Leukocyte chemotaxis (in five patient with pyoderma gangrenosum) was studied using a modification of the Boyden chamber method. In all patients the chemotactic response was significantly lower than in the controls. This abnormal chemotaxis was a result of an intrinsic neutrophil dysfunction. No significant difference was detected between the

Chemotaxis of nurse shark leukocytes

Developmental & Comparative Immunology, 1985
Studies were conducted to determine the ability of leukocytes from the nurse shark to migrate in an in vitro micropore filter chemotaxis assay and to determine optimal assay conditions and suitable attractants for such an assay. A migratory response was seen with several attractants: activated rat serum, activated shark plasma, and a pool of shark ...

Protein methylesterase and leukocyte chemotaxis

Molecular Immunology, 1980
Abstract The involvement of protein carboxylmethylesterase in leukotaxis has been studied. The enzyme is localized in the cytosolic fraction of neutrophils. In intact cells the presence of a chemoattractant induces a rapid stimulation of enzymatic activity. An half-maximal stimulation of this activity is induced by a concentration (3 n M ) of peptide
