The aim of the present study was to determine whether lipoarabinomannan (LAM), in combination with Freund's incomplete adjuvant (FIA), was able to improve cell-mediated and antibody-mediated immune responses against ovalbumin (OVA) in cattle. Twenty-three calves were assigned to four treatment groups, which were subcutaneously immunized with either OVA plus FIA, OVA plus FIA and LAM from Mycoba...

Cell-mediated immunity is critical to host defenses against the fungal infection cryptococcosis. Here, two functions critical to effective cell-mediated immunity (CMI), lymphoproliferation and cytokine release, were studied in Cryptococcus neoformans-stimulated peripheral blood mononuclear cells (PBMC) from seven healthy donors (controls) and two patients with cryptococcosis. PBMC responses to ...

T-cell lymphoproliferation are less frequent than B-cell and have some particular clinical features. We present a patient presenting with a reversible cutaneous and blood T-lymphocyte clonal expansion this case may be closed to the drug hypersensitivity syndrome.

Chronic myelocytic leukemia (CML) may display a lymphoproliferative phase (lymphoid blast crisis) that is generally of B cell phenotype. Since lymphoproliferative disorders may occur following bone marrow transplantation (BMT), it may be difficult to distinguish posttransplant relapse of CML lymphoid blast crisis from de novo lymphoproliferation. Lymphoid blast crisis cells from a patient with ...

autoimmune lymphoproliferative syndrome (alps) is a rare, inherited disorder of immune dysregulation secondary to defective lymphocyte apoptosis. this leads to uninhibited proliferation of lymphoid tissue manifesting with lymphadenopathy, hepatosplenomegaly, autoimmune cytopenia, and an increased risk of lymphoid malignancy. we report a 2 year old boy with fever, generalized lymphadenopathy, he...

Plasma for patients with primary type IV or V hyperlipoproteinemia inhibited [3H]thymidine incorporation by cultured mononuclear leukocytes. This previously unreported abnormality affected mononuclear leukocytes from patients with type IV or V hyperlipoproteinemia and from normal subjects. Patient cells incorporated [3H]thymidine normally when washed and incubated in medium containing normal pl...
