Selective Induction of Apoptosis in Antigen-Presenting Cells in Mice by Parapoxvirus ovis

Selective induction of apoptosis in antigen-presenting cells in mice by Parapoxvirus ovis.

Viruses have evolved numerous mechanisms to avoid host immune reactions. Here we report a mechanism by which Parapoxvirus ovis (PPVO) interferes with antigen presentation. PPVO (orf virus) causes orf, an acute skin disease of sheep and goats worldwide. Importantly, PPVO can repeatedly infect its host in spite of a vigorous inflammatory and host immune response to the infection. We demonstrate i...

Apoptosis induction in acute promyelocytic leukemia cells through upregulation of CEBPα by miR-182 blockage

MicroRNAs (miRNAs) involved in regulation of the genes. The CCAAT/enhancer-binding protein-α (CEBPα) is a crucial transcription factor for normal hematopoiesis and cell cycle that frequently disrupted in human acute myeloid leukemia (AML). The miR-182 up-regulation in several malignant diseases such as AML was reported, in the other hand bioinformatics analysis revealed CEBPα targeted by miR-18...

Cytokine Secretion in Monocytes and Peripheral Immune Cells: Induction of Parapoxvirus Ovis (Orf Virus) on Human Immunomodulatory Effects of Inactivated

Induction of apoptosis in human tumor cell lines by platelets

Introduction: It has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. The effect of platelets on the induction of apoptosis in tumor cells is largely unknown. Materials and methods: To investigate this effect, two human hematologic cell lines, K562 and Daudi, were independently faced with unstimulated and thromb...
