  1. 1. Monocytes and macrophages, with a focus of Crohn's disease

    Författare :Susanne Thiesen; Internmedicin - epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Crohn s disease; Cystatin C; Cytokines; Intestine; Macrophages; Monocytes; Gene-expression;

    Sammanfattning : Monocytes and macrophages are part of the body’s first line of defense, eliminating pathogens by phagocytosis or by releasing a broad array of inflammatory mediators, such as cytokines, chemokines and proteases. In humans, three subsets of monocytes are described with seemingly different functions. LÄS MER

  2. 2. Cancer and Inflammation : Role of Macrophages and Monocytes

    Författare :Alexander Hedbrant; Jonny Wijkander; Dick Delbro; Ann Erlandsson; Anita Sjölander; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M1 macrophages; M2 macrophages; colon cancer; lung cancer; prostaglandin E2; Biomedical Sciences; Biomedicinsk vetenskap;

    Sammanfattning : Macrophages are cells of the innate immune system that can be found in large quantities in cancer tumors and affect cancer progression by regulating growth and invasiveness of cancer cells. There are two main phenotypes of macrophages denoted M1 and M2. LÄS MER

  3. 3. TNFalpha expression in monocytes/macrophages

    Författare :Karolina Andersson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biomedicinska vetenskaper allmänt ; General biomedical sciences; Protein kinase; Macrophage; TNF;

    Sammanfattning : The recognition of microbes or microbial products by leukocytes is a key event in innate immunity. Binding of microbial products to cell surface receptors on phagocytes induce a response that includes the production of inflammatory mediators. One such mediator is the cytokine tumour necrosis factor alpha (TNF). LÄS MER

  4. 4. Eosinophil Cationic Protein : Expression Levels and Polymorphisms

    Författare :Jonas Byström; Helene Rosenberg; Uppsala universitet; []
    Nyckelord :Medical sciences; Eosinophils; Neutrophils; Monocytes; Macrophages; mRNA; eosinophil cationic protein; DNA; polymorphism; Hodgkin Lymphoma; asthma; allergy; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Chemistry; klinisk kemi;

    Sammanfattning : The eosinophil cationic protein (ECP) is usually associated with the eosinophil granulocyte. In this thesis the presence and production of this protein has been studied in two other cells. The circulating monocyte was found to contain ECP mRNA and small amounts of ECP, one thousand times less than that found in the eosinophil. LÄS MER

  5. 5. It Takes Two to Tango : Bacterial heterogeneity and host cell features govern Salmonella infection

    Författare :Viktor Ek; Mikael E. Sellin; Francisco García del Portillo; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Salmonella; swimming; swim pattern; targetting; virulence; invasion; host-pathogen interactions; epithelium; epithelial cells; macrophages; monocytes; monolayer; flagella; genome; genetic; barcoding; discreet-invasion; shape; morphology; antibiotics; persistence; Mikrobiologi; Microbiology;

    Sammanfattning : Salmonella enterica serovar Typhimurium (S.Tm) causes enterocolitis with significant worldwide morbidity and mortality. The general aim of this thesis is to investigate variation in host cell invasion mechanisms used by S.Tm across different host cell contexts, as well as the influence of bacterial cell-cell heterogeneity on invasion-relevant S.
