Spontaneous clearance of hepatitis C virus in an interleukin 28B favorable genotype highly prevalent area

from the first reference is, ‘‘Undifferentiated and differentiated MSC do not elicit alloreactive lymphocyte proliferative responses and modulate immune responses. The findings support that MSC can be transplantable between HLA-incompatible individuals.’’ The abstract of the second reference mentions, ‘‘In vitro data suggest that MSCs have low inherent immunogenicity as they induce little, if any, proliferation of allogeneic lymphocytes. Instead, MSCs appear to be immunosuppressive in vitro. They inhibit T-cell proliferation to alloantigens and mitogens and prevent the development of cytotoxic T-cells. In vivo, MSCs prolong skin allograft survival and have several immunomodulatory effects, which are presented and discussed in the present study. Possible clinical applications include therapy-resistant severe acute graft-versus-host disease, tissue repair, treatment of rejection of organ allografts and autoimmune disorders.’’
