Anti-thymocyte globulin (ATG) provides effective therapy for many patients with aplastic anemia, and its mechanism of action has been presumed to be secondary to lymphocytotoxicity. However, our studies of lymphocyte function in aplastic anemia show marked abnormalities of lymphokine production,
Trypanosomosis has been associated with immunosuppression, anemia and oxidative damage while selenium possesses both immunostimulatory and antioxidative effects. This study was designed to assess the effect of dietary selenium supplementation on parasitemia, anemia, survival pattern and serum
Therapy with antilymphocyte globulin (ALG) has been shown to be effective in restoring hematopoiesis to some patients with aplastic anemia. It would be useful to have a method for predicting those likely to be responders versus nonresponders. The mode of immunostimulatory action of ALG is of
Antilymphocyte globulin (ALG) and antithymocyte globulin (ATG) have an established role in the treatment of severe aplastic anaemia. The response rate ranges from 40% to 80%. Its mode of action is believed to be complement dependent lysis of immunocompetent cells which inhibit haemopoietic
BACKGROUND
Allogeneic blood transfusion is common in the treatment of neonatal anemia of prematurity or anemia due to multiple phlebotomies. The immune response of neonates to passenger leukocytes from allogeneic red cells was investigated.
METHODS
Fourteen infants (4 male, 10 female) prospectively
Antilymphocyte globulin is an immunoglobulin preparation prepared from heterologous serum after the animal (horse or rabbit) has been immunised with human lymphocytes, obtained from the thymus (antithymocyte globulin, ATG) or thoracic duct (antilymphocyte globulin, ALG). The rationale for the use of
Three moderately to broadly recognized equine infectious anemia virus (EIAV) peptides that contained helper T-lymphocyte (Th) 1 epitopes were previously identified. Although lipopeptide immunization was only weakly immunostimulatory in a preliminary study, as measured by T-lymphocyte proliferation
Loading of the major histocompatibility complex (MHC) class I molecule with peptide is mediated by the multimeric peptide-loading complex in the ER where the glycoprotein tapasin (TAPBP) is required for stabilization of the complex and for control of peptide loading onto MHC class I. To expand our
BACKGROUND
Multiple myeloma (MM) is an incurable disease characterized by clonal plasma cell proliferation and overproduction of monoclonal paraprotein, hypercalcemia, renal failure, anemia, osteolytic bone lesions, and infections. Melphalan, a nitrogen mustard, is an alkylating agent synthesized in
As an alternative to recombinant protein administration, ex vivo gene-modified cells may provide a novel strategy for systemic delivery of therapeutic proteins. This approach has been used in preclinical and clinical studies of a plethora of pathological conditions, including anemia, hemophilia and
Celiac disease is a common autoimmune disorder that has genetic, environmental, and immunologic components. It is characterized by an immune response to ingested wheat gluten and related proteins of rye and barley that leads to inflammation, villous atrophy, and crypt hyperplasia in the intestine.
Hemangiomas and lymphangiomas are two main types of angiomatous disease that occur most commonly in infancy and childhood. Most hemangiomas resolve spontaneously, but some endanger vital structures such as the lung, as in pulmonary hemangiomatosis, a rare and universally fatal disease. Occasionally,
Antithymocyte globulin (ATG) is an effective treatment in patients with severe aplastic anemia (SAA). Its mechanism of action remains unclear, although it has been assumed to be immunosuppressive. However, ATG has also been shown by several laboratories to be immunostimulatory. Recently,
Interleukin-21 (IL-21), a pleiotropic immunostimulatory type I cytokine, has anticancer effects in animal models. Preclinical studies designed to assess the safety of recombinant human IL-21 (rIL-21) for use in phase I oncology studies are described. The rIL-21 (≤3.0 mg/kg per dose) was given
In a pilot study the safety and therapeutic effects of an immunostimulatory intralymphatic treatment with natural human interleukin-2 (IL-2) in combination with zidovudine were evaluated in nine patients with AIDS. Therapy with IL-2 consisted of one subcutaneous injection of 0.1 microgram/kg IL-2,
