The combined effects of tamoxifen, a competitive inhibitor of estrogen, and type I or II interferons on the proliferation of several human breast cancer cell lines in vitro were examined. Additive antiproliferative effects were observed with interferons and tamoxifen, in two estrogen receptor positive cell lines, MCF-7 and T-47D. In MCF-7 cells neither beta ser interferon, gamma interferon, nor...
We investigated the activity of roxithromycin (RU 965) and gamma interferon alone and in combination in a murine model of toxoplasmic encephalitis. Roxithromycin at a dosage of 35 or 50 mg per mouse per day decreased mortality. Gamma interferon alone significantly prolonged time to death. When combined, the two agents were remarkably synergistic.
Determination of neopterin [D-erythro-6-(1',2',3'-trihydroxypropyl)pterin] in body fluids is a powerful diagnostic tool in a variety of diseases in which activation of cellular immune mechanisms is involved, such as certain malignancies, allograft rejection, and autoimmune and infectious diseases. In vitro, neopterin is released into the supernatant by peripheral blood-derived monocytes/macroph...
The BeWo trophoblast cell line does not constitutively express the tryptophan degrading enzyme indolamine 2,3-dioxygenase (IDO), nor can IDO expression be induced by gamma interferon. This correlates with the inability of BeWo cells to control the growth of Chlamydophila abortus, in contrast to effects observed in HeLa cells treated with gamma interferon.
The case of a previously healthy HIV seronegative woman with disseminated Mycobacterium tuberculosis infection and markedly reduced interferon gamma production is reported here. Complete healing of her disseminated lesions was seen only after addition of subcutaneous interferon gamma to her tuberculosis treatment.
Conventional antifungal therapy was not successful for a critically ill patient who had been hospitalized for 137 days in the intensive care unit with disseminated Coccidioides immitis infection and respiratory failure. The addition of interferon- gamma to the therapeutic regimen resulted in improvement and discharge from the hospital. Adjunctive interferon- gamma used in the successful treatme...
A dose of 75 mg of azithromycin per kg of body weight per day combined with a dose of 2 micrograms of gamma interferon per day and administered for 10 days protected at least 40% of mice infected with a lethal inoculum of Toxoplasma gondii. Azithromycin administered alone protected less than 10% of the mice; gamma interferon had no protective effect.
Labial biopsy specimens from eight patients with primary Sjögren's syndrome (SS), 10 patients with secondary SS, and three healthy controls were studied with monoclonal antibodies identifying HLA class I and class II antigens; interferon-alpha, beta, and gamma; interleukin 2 (IL2); and the IL2 receptor (Tac) among others. In the normal biopsy specimens there was evidence of HLA class I and, to ...
Induction of T helper type 1 responses by a polysaccharide deacetylase from Cryptococcus neoformans.
A 25-kDa cryptococcal deacetylase (d25) was found here to induce cell proliferation, as well as secretion of interleukin 2 and gamma interferon, but not interleukin 4, in spleen cells from d25-immunized or Cryptococcus neoformans-infected mice. The gamma interferon, but not the interleukin 2, response was required for the protective activities of d25 immunization in a murine cryptococcosis model.
