1. 1. Cellular Immune Responses to Cytomegalovirus

   Författare :Anna Karin Lidehäll; Olle Korsgren; Thomas Tötterman; Ineke ten Berge; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cytomegalovirus; cellular immunology; infection; immune responses; congenital infection; CD4 T cells; CD8 T cells; immunosuppressed; Clinical immunology; Klinisk immunologi;

   Sammanfattning : Cytomegalovirus (CMV) is a widespread infection affecting 50-90% of the human population. A typical silent primary infection is followed by life-long persistence in the host under control by virus-specific CD8 (“killer”) and CD4 (“helper”) T cells. LÄS MER

3. 2. Maturation of humoral immune responses : Studies on the effects of antigen type, apoptosis and age

   Författare :Karin Lindroth; Carmen Fernández; Kenneth G.C. Smith; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunology; B cell; humoral immune response; Immunology; Immunologi;

   Sammanfattning : The humoral immune response is dependent on the formation of antibodies. Antibodies are produced by terminally differentiated B cells, plasma cells. Plasma cells are generated either directly from antigen challenged B cells, memory cells or from cells that have undergone the germinal center (GC) reaction. LÄS MER

4. 3. Regulatory aspects of innate immune responses

   Författare :Ahmed El Marghani; Per-Erik Olsson; Peter Kjellén; Muhammad Zafarullah; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Innate immunity; TOM1L1; inflammatory responses; Biology; Biologi;

   Sammanfattning : Activation of innate immunity is regulated by a variety of signaling molecules within the immune cells. The present thesis was aimed to improve our understanding of innate signaling mechanism and their possible use as bio-indicators of exposure and disease. LÄS MER

5. 4. The Immune System in the Oldest-Old : Clinical and Immunological Studies in the NONA Immune Cohort

   Författare :Bengt-Olof Nilsson; Jan Ernerudh; Anders Wikby; Sture Löfgren; Karlis Pauksens; Linköpings universitet; []
   Nyckelord :Elderly; selection; health status; lymphocyte subsets; CD8; CMV; cytomegalovirus; immune risk; immune risk phenotype; IRP; T-cells; interleukin 6; IL-6; survival; mortality; antinuclear antibodies; ANA; ageing; immunosenescence; MEDICINE; MEDICIN;

   Sammanfattning : The oldest-old (people aged 80 or older) constituted 5 % of the population in Sweden in 2000, an increase from 1.5 % fifty years earlier. The immune system undergoes dramatic changes at high age, sometimes referred to as “immunosenescence”. LÄS MER

7. 5. Host-Pathogen Responses during Giardia infections

   Författare :Emma Ringqvist; Staffan Svärd; Patricia Johnson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Giardia; parasite infection; host-parasite releationship; immune activation; virulence factor; immune evasion; Cell and molecular biology; Cell- och molekylärbiologi; Microbiology; Mikrobiologi; mikrobiologi; Microbiology;

   Sammanfattning : Giardia lamblia is a eukaryotic parasite of the upper small intestine of humans and animals. The infecting trophozoite cells do not invade the epithelium lining of the intestine, but attach to the brush border surface in the intestinal lumen. The giardiasis disease in humans is highly variable. LÄS MER
