Abstract

Tumor necrosis factor (TNF) is a cytokine produced mainly by activated monocytes/macrophages. We review here data obtained in four experimental models analyzed in our laboratory: cerebral malaria, graft-versus-host disease, BCG infection, and bleomycin-induced pulmonary fibrosis. We have shown that the triggering of these pathological conditions requires activation of T lymphocytes and overproduction of TNF, since these syndromes are associated with increased production of TNF mRNA and can be prevented either by T-cell depletion or by in vivo administration of neutralizing anti-TNF antibodies. These observations suggest that TNF is a central mediator in various immunopathological conditions and thus widen the field of T-cell mediated pathology.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
