The effect of azathioprine on the kinetics of peripheral blood monocytes and peritoneal macrophages was studied in normal mice and in mice in which an inflammatory reaction was provoked.

The average duration of some phases of the cell cycle of monocyte precursors can be estimated indirectly from 3 HT labeling data of monocytes in the blood. If samples of blood are drawn at closely spaced periods after a pulse of 3 HT, the resulting labeling pattern in the rat (Whitelaw et al., ) and man (Meuret, ) resembles a series of overlapping by: Moreover, incubation of normal monocytes with AIDS serum or plasma induced CD16 expression which correlated with serum TGF-beta levels (r =P less than ) and was inhibited with a.

Blood Advances is a semimonthly medical journal published by the American Society of Hematology. It is the first journal to join the Blood family in 70 years and is a peer-reviewed, online only, open access journal. Under the direction of founding editor-in-chief Robert Negrin, MD, Stanford University Medical Center, Stanford, CA, the inaugural issue debuted on Novem Abstract.

The similarities found between morphological, cytochemical, and functional characteristics of mononuclear phagocytes, combined with knowledge about the origin and kinetics of these cells, led to the concept of the mononuclear phagocyte system (MPS) (van Furth et al.

).Cited by: Abstract. The cytochemical demonstration of peroxidatic (PO) activity is often used in studies on monocytes and macrophages. This reaction makes it possible to distinguish between resident (= tissue) macrophages on the one hand and monocytes and monocyte-derived cells on the other, since resident macrophages have PO activity in the rough endoplasmic reticulum (RER) and the nuclear envelope Cited by: Publisher Summary.

This chapter describes methods Identification and kinetics of monocytes in normal rat blood. book the isolation and in vitro maintenance of human blood monocytes. The methods have been designed to produce a pure population of blood monocytes in suspension form derived from between 10 and ml of blood and to allow the culturing of the cells for periods up to four months.

Effect of IL on cytokine production. To study the effect of exogenous IL on IL-1β, IL-6, IL (p40), and TNF-α production, THP-1 cells were stimulated with 1 μg of L-OspA or LPS per ml in the presence or absence of various concentrations (,1, 10, and ng/ml) of human Cited by:   Transplantation of CMP gave rise to all myeloerythroid but not any lymphoid progeny (except for rare B cells), while MEP gave only red cells and platelets, and GMP gave rise only to granulocytes, monocytes, and cells of the macrophage lineage, as well as all types of dendritic cells.

The identification of various subsets of monocytes has allowed researchers to address the in vivo rele vance of human monocytes by studying mouse monocytes. Inflammation, trauma and immune stimuli all cause an increased recruitment of monocytes to peripheral tissues, aiding in host defense and tissue repair (Taylor, Martinez-Pomares et al.

(A) Normal PBMCs from 60 ml of blood were equally divided for three analyses. Monocytes were separated from lymphocytes by adherence to plastic, then further activated by incubation in culture. Total time in culture is by:   Aim: To determine the characterisation of hyalocytes: the origin, phenotype, and turnover in the rodent.

Methods: To characterise the ultrastructure and distribution of hyalocytes, transmission and scanning electron microscopy was performed in rat eyes. Immunophenotypical analysis was performed by either anti-ED1 or ED2 antibodies.

To examine the origin of the hyalocytes, the chimeric mice Cited by: With Zanvil Cohn (–), van Furth identified blood monocytes as the precursors for tissue macrophages and bone marrow as the source of monocytes.

Because normal red blood cells have a lifetime in the circulation of approximately four months, it can take months for folate-deficient individuals to develop the characteristic megaloblastic anemia.

The liver is one of the largest organs in the body, weighing up to kg ( lb.) in adults [].Interestingly, although this can constitute only ~% of body weight, the liver receives around 25% of the cardiac output [].The liver is located in the upper right portion of the abdominal cavity, beneath the diaphragm and on top of the stomach, right kidney, and by: There was evidence for a concentration-related effect of UFP exposure on the percentage of blood monocytes.

In addition, monocyte expression of CD54 (ICAM-1) decreased after exposure in a concentration-response pattern (p=), with the greatest effect occurring at 0 and hours after exposure, and the differences resolved at 21 hours after. SUMMARY Professional phagocytes (polymorphonuclear neutrophils and monocytes/macrophages) are a main component of the immune system.

These cells are involved in both host defenses and various pathological settings characterized by excessive inflammation. Accordingly, they are key targets for immunomodulatory drugs, among which antibacterial agents are promising Cited by:
