The significance of atypical mononuclear leukocytes

The Journal of Pediatrics, 1962
Summary Atypical mononuclear leukocytes in routine peripheral blood smears from 20 children have been studied and the clinical features of the cases reviewed. There seems reason to believe that these atypical cells are lymphocytes in the process of maturing to histiocytes or monocytes.

Platelet aggregation inhibition by mononuclear leukocytes

Thrombosis Research, 1994
In this study we have investigated the effect of human mononuclear leukocytes (ML) on platelet aggregation. The results obtained demonstrated that coincubation of platelets with nonstimulated ML decreased platelet aggregation induced by collagen or thrombin in a concentration-dependent manner.

Effects of antigens on mononuclear leukocyte chemiluminescence

Immunological Investigations, 1985
Influenza virus and Candida albicans allergenic extract elicit alterations in the oxidative metabolic activity of human mononuclear leukocytes (MNL). MNL preparations (greater than 96% lymphocytes, less than 4% monocytes) exposed in vitro to inactivated influenza virus displayed significantly enhanced oxidative activity, as demonstrated by luminol ...

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).
