Dendritic cells (DCs) are a type of antigen-presenting cell which plays an essential role in the immune system. To clarify the influences of ionizing radiation on the differentiation to DCs, we focused on human peripheral blood monocytes and investigated whether X-irradiated monocytes can differentiate into DCs. The non-irradiated monocytes and 5 Gy-irradiated monocytes were induced into immatu...

Monocytes consist of two well-defined subsets, the Ly6C+ and Ly6C- monocytes. Both CD11b+ myeloid cells populations have been proposed to infiltrate tissues during inflammation. While infiltration of Ly6C+ monocytes is an established pathogenic factor during hepatic inflammation, the role of Ly6C- monocytes remains elusive. Mice suffering experimental African trypanosome infection die from syst...

Abstract Ceramide kinase (CERK) phosphorylates ceramide to produce ceramide-1-phosphate (C1P), which is involved in the development of metabolic inflammation. TNF-? modulates inflammatory responses monocytes associated with various disorders; however, underlying mechanisms remain not fully understood. Here, we investigated role CERK TNF-?-induced monocytes. Our results show that disruption acti...

The levels and activity of tissue transglutaminase were studied in human peripheral blood monocytes during differentiation into macrophages in vitro. The enzyme was present at low levels in freshly isolated monocytes (less than 20 ng/mg cell protein) but increased 50-fold during 10 d of adherent culture in autologous serum, reaching levels of 0.1% of total cellular protein. The rate of appearan...

BACKGROUND Three different subsets of circulating human monocytes, CD14brightCD16- (classical), CD14brightCD16+ (intermediate), and CD14dimCD16+ (non-classical) have been recently identified. It has been reported that CD14brightCD16+ monocytes are increased in rheumatoid arthritis (RA). However, the role of each monocyte subset in the pathogenesis of RA is still unclear. The purpose of this stu...

INTRODUCTION Both nonclassical and intermediate monocytes have been implicated in different inflammatory conditions. We hypothesized that these monocytes would increase during pregnancy, a condition associated with generalized activation of inflammatory responses and that they would increase even more during preeclampsia, in which inflammatory responses are further stimulated. In the present st...

In humans circulating monocytes include classical (CD14 ++ CD16 - ), intermediate + ) and non-classical/alternative monocytes, which in turn can be activated via the or alternative pathway. Pregnancy is accompanied by significant changes monocyte compartment, manifested an increase number of including proportion a change their function. However, functional properties subsets during gestation re...

introduction: studies have shown that insufficient recovery between sessions causes immune suppression. the aim of this study was to investigate the effect of repeated bouts resistance and endurance exercise on blood leukocytes, lymphocytes, neutrophils, monocytes count and plasma cortisol levels in athlete girls. materials and methods: 9 athlete girls (ages, 20-25 years), participated in the s...
