The assessment of intracellular cytokines at the single-cell level by flow cytometry has recently become a potent tool in many areas of cell biology and in defining the role of cytokines in various human diseases. Three-color flow cytometry for detection of intracellular cytokines combined with simultaneous determination of lymphocytes (CD3(+) and CD4(+))(More)
In this report we investigated the immunopharmacological role of selective and nonselective phosphodiesterase (PDE) inhibition in regulating the inhibitory-kappaB (IkappaB-alpha)/nuclear factor-kappaB (NF-kappaB) signaling transduction pathway. In fetal alveolar type II epithelial cells, PDE blockade at the level of the diverging cAMP/cGMP pathways(More)
OBJECTIVE To evaluate the influence of the methylxanthine derivative, pentoxifylline, on plasma levels of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1, and IL-6 in prematurely delivered infants with generalized bacterial infections and to assess the effect of this immunomodulating drug on the clinical outcome in newborns with sepsis. DESIGN A(More)
BACKGROUND Severe combined immunodeficiency (SCID) is a syndrome characterized by profound T-cell deficiency. BCG vaccine is contraindicated in patients with SCID. Because most countries encourage BCG vaccination at birth, a high percentage of patients with SCID are vaccinated before their immune defect is detected. OBJECTIVES We sought to describe the(More)
Mendelian susceptibility to mycobacterial diseases (MSMD) is a rare syndrome, the known genetic etiologies of which impair the production of, or the response to interferon-gamma (IFN-γ). We report here a patient (P1) with MSMD whose cells display mildly impaired responses to IFN-γ, at levels, however, similar to those from MSMD patients with autosomal(More)
PROBLEM Antisperm antibodies induced in prepubertal boys with testicular failures were characterized by using four techniques of antibody detection. The reactivity of circulating antisperm antibodies in prepubertal boys and the reactivity of antibodies in sera samples of adult fertile and infertile males were compared against the same sperm antigenic pools(More)
A shot in the arm for cancer treatment: two MUC1 tetanus toxoid vaccines were synthesized and induced a strong immune response in mice. The antibodies elicited by the vaccines show a high selectivity for the tumor cells in mammary carcinoma tissues and also distinguish between tumor tissues at different stages.
The aim of this study was to evaluate the B-cell compartment in the peripheral blood of children with different types of hipogammaglobulinemia: common variable immunodeficiency (CVID), transient hypogammaglobulinemia of infancy (THI), and selective IgA deficiency (SIgAD). We analyzed by flow cytometry the changes in the B-cell subsets with age and showed(More)
We have studied the effect of intravenous immunoglobulins (IVIG) on monocyte subpopulations and cytokine production in patients with CVID. The absolute number of CD14(+)CD16(++) monocytes decreased on average 2.5-fold 4h after IVIG and after 20h returned to the baseline. The cytokine level in the supernatants of peripheral blood mononuclear cells (PBMC)(More)
