Antilymphocyte and antithymocyte globulins (ALG) are currently used as immunosuppressive agents in clinical transplantation and for the treatment of severe aplastic anemia. ALG contain a mixture of antibodies that recognize Tand B-cell-specific antigens but mostly nonlineage-specific molecules. We reported previously that ALG could inhibit the proliferation of activated B cells and B cell lines...

BACKGROUND Fibrodysplasia ossificans progressiva is a heritable disorder of connective tissue characterized by congenital malformation of the great toes and postnatal formation of ectopic bone. Although the disorder was first described more than 300 years ago, the genetic defect and pathophysiology remain unknown. Bone morphogenetic proteins are potent bone-inducing morphogens that participate ...

2-Chlorodeoxyadenosine (CdA), an adenosine-deaminase-resistant purine deoxynucleoside, is markedly toxic toward human T-lymphoblastoid cell lines in vitro and is an effective agent against L1210 leukemia in vivo. The present studies have examined the toxicity, and in some cases, metabolism, of CdA in (1) multiple established human cell lines of varying phenotype, (2) leukemia and lymphoma cells...
