Exosomes (EXO) derived from tumour cells have been used to stimulate antitumour immune responses, but only resulting in prophylatic immunity. Tumour-derived heat shock protein 70 (HSP70) molecules are molecular chaperones with a broad repertoire of tumour antigen peptides capable of stimulating dendritic cell (DC) maturation and T-cell immune responses. To(More)
Tumor cell apoptosis induced by radiation therapy results in apoptotic tumor cells and apparition of membrane blebs termed apoptotic bodies (APB). The immune responses induced by apoptotic tumor cells have been extensively studied. However, the role of APB in modulation of tumor immune responses is elusive. In this study, we induced apoptosis in 90%(More)
Chronic myelogenous leukemia is caused by a reciprocal chromosomal translocation of human chromosomes 9 and 22. The resulting fusion protein, p210Bcr/Abl, has enhanced tyrosine kinase activity compared with the normal cellular homologue, p145c-Abl. Expression of this chimeric protein in hematopoietic cell lines results in a rapid progression to growth(More)
Granulocyte-macrophage colony-stimulating factor (GM-CSF) activates a broad range of myeloid cells through binding to high-affinity receptors (GM-CSF-R) consisting of at least two distinct subunits, GM-CSF-R alpha and GM-CSF-R beta. The genes of these GM-CSF-R subunits have been identified recently, but little is known about the regulation of their(More)
Steel factor (SF) synergizes with a variety of hemopoietins to support the growth and differentiation of human progenitor cells. The human factor-dependent cell line MO7 has been used as a model to study the interaction of SF with other growth factors such as GM-CSF, because both factors support the proliferation of this cell line and are synergistic in(More)
