2. 1. Modulation of B cell access to antigen by passively administered antibodies : an explanation for antibody feedback regulation?

   Author : Hui Xu; Birgitta Heyman; Helena Harris; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgG; IgG3; IgE; suppression; enhancement; epitope masking; antigen transport; antigen presentation; follicular B cells; marginal zone B cells; Immunologi; Immunology;

   Abstract : Antibody responses can be up- or down-regulated by passive administration of specific antibody together with antigen. Depending on the structure of the antigen and the antibody isotype, responses can be completely suppressed or enhanced up to a 1000-fold of what is seen in animals immunized with antigen alone.

4. 2. Anomalies in humoral immunity in the NOD mouse : contribution to the progression of type 1 diabetes

   Author : Radha Thyagarajan; Kristina Lejon; Per-Arne Oldenborg; Susanna Cardell; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 1 Diabetes; NOD mouse; B cells; IgE; TACI; BAFF; immunologi; Immunology;

   Abstract : The non-obese diabetic (NOD) mouse is widely used model Type 1 diabetes (T1D), a chronic inflammatory disease characterized by destruction of the insulin producing β cells in the islets of Langerhans by immune cells. The classical symptoms include increased glucose levels in urine and blood, frequent urination and enhanced thirst. READ MORE

5. 3. Immunoregulation in an experimental model of allergic asthma

   Author : Magnus Korsgren; Avdelningen för klinisk kemi och farmakologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allergic asthma; macrophage migration inhibitory factor; eosinophils; gd T cells; NK1.1 T cells; natural killer cells; immunoglobulins; B cells; innate immunity; allergic airway inflammation; immediate hypersensitivity; Physiology; Fysiologi; Immunology; serology; transplantation; Immunologi; serologi;

   Abstract : In allergic asthma the immune response to antigen is inappropriate, leading to an inflammatory process in the respiratory mucosa. To further elucidate immunological mechanisms involved in the development of such inflammation, control mice and mice deficient in selected cell types or proteins, were used in experimental models of allergic asthma and anaphylaxis.

6. 4. Experimental and Clinical Studies of SLPI, with Special Reference to IgE-Mediated Allergic Reactions

   Author : Ulla Westin; Malmö Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; in situ hybridisation; immunohistochemistry; allergic rhinitis; atopic subjects; IgE-mediated histamine release; mast cell proteases; plasma protease inhibitors; SLPI; human leukocyte proteases; Immunology; serology; transplantation; Immunologi; serologi;

   Abstract : In this study we demonstrated the production of SLPI (Secretory Leukocyte Protease Inhibitor) in serous glands in the nasal mucosa. We have shown that the pattern of the expression of mRNA corresponds to the encoded protein. The encoded protein was detected by immunohistochemical methods and mRNA was discovered by in situ hybridisation. READ MORE

7. 5. Mast cells: bad enemies or good friends? : A study of the effects of IgG immune complexes on mast cell biology

   Author : Lisa M Larsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mast cell; Fc receptor; Apoptosis; Immune complex; Adjuvant; CTA1-DD.;

   Abstract : Mast cells are classically defined as bad enemies to human health due to their critical involvement in IgE-dependent allergy by virtue of the expression of the high affinity IgE receptor, FcgammaRI, on these cells. However, mouse mast cells also express FcgammaRIIB and FcgammaRIIIA, two receptors that bind IgG especially in the form of IgG immune complexes. READ MORE
