  2. 21. Integrin-interacting proteins in human cancer progression

    Author : Zhengwen An; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Integrins are the major transmembrane receptors for the extracellular matrix (ECM) which regulate a diverse array of cellular functions crucial to tumor cell migration, invasion, proliferation and survival. Integrins contact the ECM via their N-terminal extracellular domains and connect to the intracellular environment via the C-terminal cytoplasmic domains. READ MORE

  4. 22. Intraovarian mechanisms influencing the human corpus luteum

    Author : Ulrika Ottander; Torbjörn Hillensjö; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Corpus luteum; steroidreceptors; progesterone; LH hCG; PGF2α; ultrasonography;

    Abstract : Introduction: The human corpus luteum (CL) is a transient endocrine gland, only functionally active for about 14 days. Its principal function is to produce and secrete progesterone and thereby support the endometrium for implantation of a blastocyst and prevent rejection of the developing embryo. READ MORE

  5. 23. On the origin of B cells. Elucidating the Role of Tyrosine Kinase Receptors in B Cell Development

    Author : Alya Zriwil; Avdelningen för molekylär hematologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoiesis; B cell development; cytokine; tyrosine kinase receptors;

    Abstract : B cells are essential cells that are part of the adaptive immune system with the capacity to produce antibodies against exogenous antigens. These cells are produced through a process called hematopoiesis, tightly regulated by extrinsic and intrinsic factors. READ MORE

  6. 24. Development of novel DNA vaccine and immunotherapeutic approaches

    Author : Maroof Hasan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Many potential DNA vaccination and immunotherapeutic strategies has been explored in both animal models and human settings in recent years. However, the failure of efficient and safe method development suggests that it is time to rethink, since more innovative approaches are needed for better control of infection and immunotherapy.

  7. 25. Transcriptional regulation of development in time and space

    Author : Daniel W Hagey; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Human development requires the generation of trillions of cells with myriad functions from a single cell. This requires that restriction of stem cell fate competence and proliferation are precisely temporally and spatially patterned as the embryo grows. READ MORE
