  1. 1. Functional properties of antibodies in resistance against HIV-1 infection

    Författare :Claudia Devito; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : During the last years a few populations who remain uninfected despite repeated HIV-1 viral exposures have been described. Several mechanisms were suggested to be associated with this natural resistance including HIV-1-specific cell- mediated and humoral immune responses, as well as mutations affecting receptors for virus entry.

  3. 2. Functional studies on the interaction of immunoglobulins with HIV-2 envelope

    Författare :Samer Sourial; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HIV; Glycoprotein; Antibodies lgA IgG; V3; CD4; Neutralization; Immunization;

    Sammanfattning : Infection with HIV-2 has a much more limited geographic distribution than HIV-1, being less readily transmitted and is generally less pathogenic. The role of immunoglobulins in defence against pathogens in different body compartments is known, where IgG is the principal isotype in the blood and extracellular fluid while lgA predominates in the mucosal compartment.

  4. 3. HIV-induced humoral immune response with specific relevance to IgA

    Författare :Pia Skott; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :HIV; secretory lgA; neutralizing antibodies; mucosal immunity;

    Sammanfattning : Human Immunodeficiency Virus (HIV) transmission occurs primarily after hetero- and homosexual contact and across mucosal surfaces. The immune response in mucosal tissues is typified by secretory immunoglobulin A (SIgA), which is the predominant lg class in human external secretions. LÄS MER

  5. 4. Puumala hantavirus : immune responses and vaccines

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

    Sammanfattning : 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. LÄS MER

  7. 5. Diagnostic methods for demonstration of intrathecal synthesis of immunoglobulines within the central nervous system

    Författare :Sten Öhman; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This thesis is based upon studies of quantitative and qualitative determinations of immunoglobulins A, G, and M (lgA, IgG, and IgM) in cerebrospinal fluid (CSF) and in serum. Inflammatory diseases, such as multiple sclerosis and infections (e.g. LÄS MER
