abstract background b cells play an important role in the immune system due to production of the immunoglobulin and secreting several cytokines. it has been shown that b cells produced successfully in the presence of stem cell factor (scf) and flt3 ligand (flt3l). il2, il7, and il15 cytokines as  -common family have an essential cytokines may support either synergistically or in an additi...

Hemophagocytic lymphohistiocytosis (HLH) is a rare disorder of the mononuclear phagocytic system, characterised by histiocyte and lymphocyte activation. It can be classified as primary secondary HLH. Primary HLH usually presents in childhood, associated with gene mutations. Secondary adulthood, due to an underlying infection, autoimmune disease or malignancy. We describe case acute hepatitis-A ...

Background: The mammalian target of rapamycin (mTOR) is important in hematopoiesis. Despite the central role of mTOR in regulating the differentiation of immune cells, the effect of mTOR function on cord blood mononuclear cells is yet to be defined. Objectives: To evaluate the effect of mTOR inhibition, using rapamycin on the proliferation and apoptosis of cord blood mononuclear cells, as well ...

The concentration of IgG and IgA was measured in the supernatants of peripheral blood mononuclear cells and of cells harvested from the intestinal lamina propria, which were cultured in vitro in the presence or absence of mitogens. The lamina propria mononuclear cells were harvested by collagenase digestion of macroscopically normal mucosa from 10 fresh surgical resections for carcinoma. Secret...

Phosphorylation of calix[4]arenes imparts an increased solubility and facilitates drastically changed coordination toward lanthanide ions, resulting in mononuclear double–decker complexes.

The chemotactic migration in vitro of peripheral blood, intestinal mucosal, and mesenteric lymph node mononuclear cells has been assessed in patients with colorectal carcinoma. Peripheral blood mononuclear cells of patients exhibited normal chemotaxis. For control patients with non-malignant, non-inflammatory intestinal disease, the chemotaxis of mucosal mononuclear cells was similar to that of...
