Platelet aggregating substance from mononuclear leukocytes

Prostaglandins, Leukotrienes and Medicine, 1986
Human peripheral blood mononuclear leukocytes (ML) in suspension stimulated with arachidonic acid (AA) were able to induce platelet aggregation. Shape change followed by first and second wave aggregation was the pattern of the platelet response. ML not treated with AA did not induce platelet aggregation nor did AA done at the concentration employed ...

C5a: A Chemotactic Factor for Mononuclear Leukocytes

The Journal of Immunology, 1971
Abstract Cleavage of guinea pig C5 results in the release of a biologically active fragmentation product (C5a) which enhances vascular permeability, contracts smooth muscle and is chemotactic for guinea pig and rabbit polymorphonuclear leukocytes (PMNs).

Interleukin‐1 and tumor necrosis factor production by tumor‐associated mononuclear leukocytes and peripheral mononuclear leukocytes in cancer patients

International Journal of Cancer, 1988
AbstractThe production of interleukin‐I (IL‐I) and tumor necrosis factor (TNF) by tumor‐associated mononuclear leukocytes (TAML) and peripheral mononuclear leukocytes (PBML) from 9 otherwise untreated patients with a variety of malignancies (lung, sarcoma, stomach, renal) was assessed.

Determination of beta adrenoceptor density on rabbit mononuclear leukocytes

Journal of Pharmacological Methods, 1988
The purpose of the present study was to devise a technique for the isolation of a relatively homogeneous mononuclear leukocyte (MNL) preparation from rabbit whole blood and determine the density and affinity of beta-adrenoceptors on MNL. A modified method based upon that by Böyum was developed to maximize isolation of MNL from red blood cells (RBC ...

MIGRATION INHIBITION OF HUMAN LEUKOCYTES MIXED WITH PHYTOHEMAGGLUTININ‐PREINCUBATED MONONUCLEAR LEUKOCYTES

Allergy, 1975
An in vitro test able to demonstrate phytohemagglutinin (PHA)-induced migration inhibition of human peripheral blood leukocytes was investigated. The migration inhibition was demonstrated by the agarose migration technique. Purified mononuclear leukocytes which had been incubated for 30 min with PHA, then washed and added to non-separated leukocytes ...

Effects of endothelial cells and mononuclear leukocytes on platelet aggregation

Haematologia, 2000
Although normal vascular endothelium prevents adhesion and aggregation of platelets by the release of nitric oxide (NO) and prostacyclin, the endothelium exposed to oxidized low density lipoprotein (LDL) may be damaged, damage that may include a reduction in its secretory capacity.

The production of growth hormone by subpopulations of rat mononuclear leukocytes

Cellular Immunology, 1991
In this study we analyzed the production of GH mRNA and secretion of GH by purified subpopulations of rat lymphoid cells. The data demonstrate that mononuclear leukocytes from various tissues, including spleen, thymus, bone marrow, Peyer's patches, and peripheral blood, all have the ability to produce GH mRNA and secrete GH.

Corticosteroid receptors and lymphocyte subsets in mononuclear leukocytes in aging

American Journal of Physiology-Endocrinology and Metabolism, 1992
Plasma cortisol and aldosterone levels and number of related receptors in mononuclear leukocytes were measured in 49 healthy aged subjects (62-97 yr) and in 21 adult controls (21-50 yr). In all subjects, in addition, lymphocyte subsets were determined as an index of corticosteroid action.

Depressed Mononuclear Leukocyte Chemotaxis in Thermally Injured Patients

The Journal of Immunology, 1977
Abstract Microbial infection is the leading cause of morbidity and mortality in thermally injured patients. Since normal mononuclear leukocytes (MNL) function is essential in host defense, the chemotactic response of MNL from 25 thermally injured patients was evaluated in vitro.

Mononuclear leukocytes in the newt limb blastema: in vitro behavior

The International Journal of Developmental Biology, 1994
Since the precise interactions of the various newt limb blastema cell types (pleiomorphic, bipolar, signet and multinucleated cells) with one another are difficult to ascertain in vivo, in this study we describe the in vitro behavior and interactions of these cell types with one another.
