Mononuclear phagocytes and dendritic leukocytes in the skin

Clinics in Dermatology, 1996
P arasitic microorganisms have evolved to become dependent on other organisms for their successful life cycle. This is achieved through a variety of interactions with defined tissues, cells, and molecules of the parasite-carrier organisms (hosts/reservoirs, vectors).

Humoral Mediators of Chemotaxis of Mononuclear Leukocytes

Journal of Infectious Diseases, 1972
In-vitro studies of chemotaxis of mononuclear leukocytes (MNLs) were performed to characterize humoral mediators governing the accumulation of these cells at inflammatory sites. Two humoral factors that attract MNLs in vitro were found. The first was a heat-labile factor (mol wt, 90,000) present in untreated guinea-pig serum and plasma.

Glucocorticoid Receptor in Circulating Mononuclear Leukocytes

Endocrinology, 1979
Binding of [3H]dexamethasone ([3H]Dex) and [3H]cortisol to normal female goat mononuclear leukocytes (MNL) was studied at 4 and 20 C. Dissociation studies of [3H]Dex and [3H]cortisol from MNL after 3 h of incubation at 20 C indicated the presence of at least two components; a small pool with a dissociation rate constant (kOfr) of 15 ± 8 x 10-3 min-1 ...

The Influence of Mononuclear Leukocytes on the Chemotactic Responsiveness of Polymorphonuclear Leukocytes of Bovines

Journal of Veterinary Medicine, Series B, 1990
SummaryPolymorphonuclear leukocytes (PMN) isolated from the blood of bovines which do not react with an influx of cells into the milk upon intramammary administration of low doses of endotoxin (Group II), show a diminished chemotactic activityin vitroas compared to PMN of bovines which do respond to intramammary endotoxin administration (Group I; 8 ...

Production of immunoreactive growth hormone by mononuclear leukocytes

The FASEB Journal, 1988
In the present study, we evaluated whether mononuclear leukocytes could synthesize and secrete growth hormone (GH) in vitro. By using RNA slot blot analysis, we detected maximum spontaneous levels of specific GH mRNA in the cytoplasm of rat leukocytes after a 4‐h incubation.

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 ...
