The Dominant Source of CD4 + and CD8 + T-Cell Activation in HIV Infection Is Antigenic Stimulation (2009)

Mette D. Hazebergh, Dörte Hamann, Sigrid A. Otto, Frank Miedema, ...

Summary: To distinguish between antigenic stimulation and CD4 + T-cell homeostasis as the cause of T-cell hyperactivation in HIV infection, we studied T-cell activation in 47 patients before and...

T-cell division in human immunodeficiency virus (HIV)-1 infection is mainly due to immune activation: a longitudinal analysis in patients before

Antibodies to mutated citrullinated vimentin and disease activity score in early arthritis: a cohort study (2008)

Ursum, Jennie, Nielen, Markus MJ, Van Schaardenburg, Dirkjan, Van Der Horst, Ann R, Van De Stadt, Rob J, Dijkmans, Ben AC, ...

Abstract Introduction The aim of our study was to investigate the association between arthritic disease activity and antibodies to mutated citrullinated vimentin (anti-MCV), because such a relation...

Deficiency of functional mannose-binding lectin is not associated with infections in patients with systemic lupus erythematosus (2006)

Bultink, Irene EM, Hamann, Dörte, Seelen, Marc A, Hart, Margreet H, Dijkmans, Ben AC, Daha, Mohamed R, ...

Abstract Infection imposes a serious burden on patients with systemic lupus erythematosus (SLE). The increased infection rate in SLE patients has been attributed in part to defects of immune defence....

Evidence that human CD8+CD45RA+CD27– cells are induced by antigen and evolve through extensive rounds of division (1999)

Hamann, Dörte, Kostense, Stefan, Wolthers, Katja C., Otto, Sigrid A., Baars, Paul A., Miedema, Frank, ...

We recently showed that circulating human CD8+ effector cells have a CD45RA+CD27– membrane phenotype. In itself this phenotype appeared to pose a paradox: CD45RA, a marker expressed by...

Distribution of Lymphocyte Subsets in Healthy Human Immunodeficiency Virus-Negative Adult Ethiopians from Two Geographic Locales

Kassu, Afework, Tsegaye, Aster, Petros, Beyene, Wolday, Dawit, Hailu, Ermias, Tilahun, Tesfaye, ...

Immunological values for 562 factory workers from Wonji, Ethiopia, a sugar estate 114 km southeast of the capital city, Addis Ababa, Ethiopia, were compared to values for 218 subjects from Akaki,...

Longitudinal Phenotypic Analysis of Human Immunodeficiency Virus Type 1-Specific Cytotoxic T Lymphocytes: Correlation with Disease Progression

Ogg, Graham S., Kostense, Stefan, Klein, Michel R., Jurriaans, Suzanne, Hamann, Dörte, McMichael, Andrew J., ...

Few studies have examined longitudinal changes in human immunodeficiency virus type 1 (HIV)-specific cytotoxic T lymphocytes (CTL). To more closely define the natural history of HIV-specific CTL, we...

Phenotypic and Functional Separation of Memory and Effector Human CD8+ T Cells

Hamann, Dörte, Baars, Paul A., Rep, Martin H.G., Hooibrink, Berend, Kerkhof-Garde, Susana R., Klein, Michèl R., ...

Human CD8+ memory- and effector-type T cells are poorly defined. We show here that, next to a naive compartment, two discrete primed subpopulations can be found within the circulating human CD8+ T...
