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

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

   Abstract : 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. READ MORE

4. 2. Humoral immune responses to allergens in early childhood

   Author : Kaja Julge; Örjan Strannegård; Sirje Velbri; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Sensitivity to eight standardized allergen extracts (Solu-Prick SQ, ALK, Hørsholm, Denmark) was assessed in 1580 schoolchildren. The prevalence of atopic sensitization among these 10-12-year-old children was 3--4 times lower in Estonia (8.1-14.3%) than in Sweden (24. READ MORE

5. 3. Feedback Enhancement of Immune Responses by IgE, IgM, and IgG3 Antibodies

   Author : Zhoujie Ding; Birgitta Heyman; Eva Severinson; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgE; IgM; IgG3; antibody responses; T-cell responses; antigen transportation; antigen presentation; complement; complement receptors 1 and 2; Immunologi; Immunology;

   Abstract : Antibodies can enhance or suppress the immune responses against their specific antigens. This phenomenon is known as antibody-mediated feedback regulation. We have studied the mechanisms underlying IgE-, IgM-, and IgG3-mediated enhancement of immune responses in mouse models using intravenous immunization. READ MORE

6. 4. Puumala hantavirus : immune responses and vaccines

   Author : Cristina de Carvalho Nicacio; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Hantavirus; Puumala virus; nucleocapsid protein; neutralizing antibodies; Fab fragment; combinatorial library; phage-display; IgA; cellular immunity; cross-protection; intranasal vaccination;

   Abstract : Hantaviruses (family Bunyaviridae) is a group of closely related zoonotic rodent-borne viruses that are transmitted to humans through inhalation of infected rodent excreta. They cause hemorrhagic fever with renal syndrome (HFRS) or hantavirus pulmonary syndrome (HPS) with varying degree of severity depending on the causative virus. READ MORE

7. 5. Mechanisms for immune escape in epithelial ovarian cancer

   Author : Pernilla Israelsson; Ulrika Ottander; Lucia Mincheva-Nilsson; Eva Lundin; Ivan Nagaev; Karin Sundfeldt; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human; ovarian cancer; high-grade serous cancer; EOC; HGSC; HGSOC; tumor microenvironment; immune escape; immune suppression; cytokines; exosomes; NKG2D; MICA B; ULBP1-3; DNAM-1; surgery; obstetrik och gynekologi; Obstetrics and Gynaecology;

   Abstract : Tumors develop mechanisms to subvert the immune system, constituting immune escape. Epithelial ovarian cancer (EOC), the deadliest of all gynecological malignancies, uses a variety of mechanisms to undermine immune surveillance, aiding its establishment and metastatic spreading.
