  1. 1. Rules of engagement - Regulation of complement response in tissue

    Författare :Anas Haider Abu-Humaidan; Infektionsmedicin; []
    Nyckelord :Complement system; Complement activation; Complement regulation; terminal complement complex; Staphylococcus auereus; atopic dermatitis; head and neck cancer; epidermal growth factor receptor; EGFR;

    Sammanfattning : Always in motion and probing for danger, complement proteins are found in every space and notch of the body. Their omnipresence combined with an ability to wreak havoc when activated, mandates a strong leash! The how, when, and where to unleash or constrain the complement response remain partly answered questions, despite the significant progress made in the field in the past 100 years. LÄS MER

  2. 2. The complement system in stherosclerosis and arthritis

    Författare :Linda Persson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :complement; C3; factor B; ASP; atherosclerosis; hyperlipidemia; arthritis;

    Sammanfattning : The complement system plays an essential role in the humoral immune response. Activated complement has diverse functions, including the initiation of inflammation, recruitment of leukocytes, clearance of immune complexes, neutralization of pathogens, regulation of antibody responses and disruption of cell membranes.

  3. 3. NO Effect on Inflammatory Reaction in Extracorporeal Circulation : Ex vivo Studies

    Författare :Mika Lahtinen; Jan Borowiec; Per Venge; Vibeke Videm; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Cardiac surgery; extracorporeal circulation; inflammatory reaction; NO; degranulation; neutrophil; eosinophil; basophil; complement; contact system; coagulation; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Clinical Chemistry; klinisk kemi;

    Sammanfattning : Nitric oxide (NO) is expressed in inflammatory tissues. However, NO effects are controversial in inflammation; NO is described as acting in a dose dependent manner and possess both pro-inflammatory and anti-inflammatory properties. LÄS MER

  4. 4. Effects of Complement Opsonization of HIV on Dendritic Cells : and Implications for the Immune Response

    Författare :Rada Ellegård; Marie Larsson; Jorma Hinkula; Johan D Söderholm; William Paxton; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; HIV; dendritic cells; complement; innate immune response; TLR signaling; T cell activation; NK cells; inflammation; antiviral response; immune evasion;

    Sammanfattning : Dendritic cells are key players during HIV pathogenesis, and shape both the immediate immune response at the site of infection as well as directing the adaptive immune response against the virus. HIV has developed a plethora of immune evasion mechanisms that hijack dendritic cell functions, suppressing their ability to mount an accurate immune response and exploiting them for efficient viral transfer to target T cells.

  5. 5. Antibody Feedback Regulation and T Cells

    Författare :Fredrik Carlsson; Birgitta Heyman; Alf Grandien; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fc receptors; B cell; T cell; antigen presentation; complement receptors; complement; IgE; IgG3; CD23; antibody; Immunology; Immunologi;

    Sammanfattning : Antibodies, passively administered or actively produced, regulate immune responses to the antigen they recognize. This phenomenon is called antibody-mediated feedback regulation. Feedback regulation can be positive or negative, resulting in >1000-fold enhancement or >99% suppression of the specific antibody response. LÄS MER
