In this study, genistein, a selective protein tyrosine kinase (PTK) inhibitor, inhibited peripheral blood mononuclear cell (PBMC) proliferation and interleukin-2 production from cultures that were stimulated with phytohemagglutinin (PHA), phorbol 12-myristate 13-acetate (PMA) plus A23187, or PHA plus PMA, and genistein effectively blocked the PHA plus IL-2-induced PBMC proliferation. Further, w...

Peripheral blood mononuclear cells (PBMC) harbored TT virus (TTV) of genotypes (3 and 4) different from those (1 and 2) of free virions in plasma of the same individuals. PBMC may act as a reservoir, and TTV of particular genotypes might have tropism for hematopoietic cells.

Methods We introduced Vpu start codon mutation and point substitution in p17 Gag matrix (L30E) in HIV-1 pNLAD8 through PCR. Progeny viruses were produced in two cell-types: 293T and HeLa by transfection. Infectivity potential of Vpu+/Vpuviruses carrying Gag (L30E) mutation was assessed in TZM-bl cell line and their replication potential in peripheral blood mononuclear cells (PBMC) and monocyte-...

background: atherosclerosis, a chronic inflammatory disease of the vessel wall is characterized by local and systemic immune responses to a variety of antigens. oxidized low-density lipoprotein (oxldl) is considered as an important determining factor in the pathogenesis of atherosclerosis. objective: the purpose of this study was to investigate the degree of peripheral blood mononuclear cells (...

The induction of IL-12 and IL-10 production by the immunomodulatory C3 binding glycoprotein (C3bgp) was studied on human peripheral blood mononuclear cells (PBMC). Isolated PBMC from healthy human donors were cultured 24 hours with C3bgp isolated from Cuscuta europea. We studied also the influence of C3bgp on the cytokine production in LPS-, PHAand PWM-stimulated PBMC. The levels of these cytok...

Figure 1. Detection of Borna disease virus (BDV)–specific nucleic acid in peripheral blood mononuclear cells (PBMC) of a man with chronic fatigue syndrome (CFS), by nested and seminested polymerase chain reaction assays. Lanes: A, BDV-negative PBMC; B, BDV-specific amplicates from PBMC of patient with CFS; M, size marker (100-bp DNA ladder). Demonstration of Borna Disease Virus Nucleic Acid in ...

Replication of measles virus was restricted in human peripheral blood mononuclear cells (PBMC). However, in in vitro-infected, unstimulated cells, active synthesis of viral RNA and proteins occurred, while the release of infectious virus could not be detected. Stimulation with PHA caused a productive infection cycle comparable to the lytic infection. Replication of viral RNA was demonstrated in...

Introduction Enthesitis Related Arthritis Category of Juvenile Idiopathic Arthritis (JIA-ERA) is the most common category of JIA seen in Asian Indians. Transcriptome analysis is a useful tool to analyse pathways involved in disease pathogenesis. Peripheral blood mononuclear cells (PBMC) and SFMC analysis showed involvement of innate immune cells in JIA-ERA. However PBMC/SFMC have variable numbe...

Previous reports showed that granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood mononuclear cells (G-PBMC) are hyporesponsive to alloantigen compared with control PBMC. In the current study, neutralizing antibodies to interleukin-10 (IL-10) increased the proliferative response of G-PBMC to alloantigen by 50. 14% (+/- 12.79%; n = 8), whereas the proliferative response of co...

White-tailed deer (Odocoileus virginianus) are reservoirs for Mycobacterium bovis in northeast Michigan, USA. Production of nitric oxide (NO) by activated macrophages is a potent mechanism of mycobacterial killing. The capacity of macrophages to produce NO, however, varies among mammalian species. The objective of this study was to determine if mononuclear cells from white-tailed deer produce n...
