Quantification Analysis of Dot Blot Assays for Human Immunodeficiency Virus Type 1 and 2 Antibodies
Objective Dot Blot (DB) assay provides highly specific results, but usually not reliable for quantification of antibody production. The need for a more objective DB assay to provide a better definition of the immune status, against HIV antigens, promoted this study to be done to develop a quantitative DB assay. Material and Methods Dot blot (DB) strips for antibodies directed to human immuno...
متن کاملEVALUATION OF CELLULAR IMMUNE RESPONSES TO AMASTIGOTE SOLUBLE Leishmania major ANTIGENS IN RECOV ERED CASES OF CUTANEOUS LEISHMANIASIS
This study was performed in order to define the cellular immune response of 12 recovered cutaneous leishmaniasis subjects to different soluble antigens of the amastigote form of Leishmania major. A soluble leishmanial antigen preparation (SLA) derived from highly-purified amastigotes from infected nude mice was fractionated by Mono Q column using Fast Protein Liquid Chromatography (FPLC) s...
متن کاملReal-time PCR assay for clinical management of human immunodeficiency virus-infected patients with visceral leishmaniasis.
To evaluate the usefulness of a real-time PCR for Leishmania DNA in the diagnosis and follow-up of patients with human immunodeficiency virus type 1 (HIV-1) and Leishmania coinfection, Leishmania DNA levels were measured in whole peripheral blood from 25 HIV-infected patients with clinical features suggestive of visceral leishmaniasis. Leishmania DNA was detected in 10 of 25 patients with micro...
متن کاملApoptotic induction induces Leishmania aethiopica and L. mexicana spreading in terminally differentiated THP-1 cells.
Leishmaniasis develops after parasites establish themselves as amastigotes inside mammalian cells and start replicating. As relatively few parasites survive the innate immune defence, intracellular amastigotes spreading towards uninfected cells is instrumental to disease progression. Nevertheless the mechanism of Leishmania dissemination remains unclear, mostly due to the lack of a reliable mod...
متن کاملIndications of the protective role of natural killer cells in human cutaneous leishmaniasis in an area of endemicity.
The role of natural versus acquired immunity to Leishmania aethiopica infection in humans is the focus of our studies. We found in previous studies that mononuclear cells from nonexposed healthy Swedish donors responded to Leishmania antigen stimulation by proliferation and gamma interferon production. The main cell type responding was CD3- CD16/56+ natural killer (NK) cells. These findings led...
