  2. 11. Xylem cells cooperate in the control of lignification and cell death during plant vascular development

    Author : Sacha Escamez; Hannele Tuominen; Andrew Groover; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Xylem; Arabidopsis; programmed cell death; tracheary element; xylem vessel; autophagy; metacaspase; lignin; secondary cell wall; chromatin; gene expression;

    Abstract : The evolutionary success of land plants was fostered by the acquisition of the xylem vascular tissue which conducts water and minerals upwards from the roots. The xylem tissue of flowering plants is composed of three main types of cells: the sap-conducting tracheary elements (TE), the fibres which provide mechanical support and the parenchyma cells which provide metabolic support to the tissue.

    Abstract : Stroke is a major cause of death and adult disability in the western world. Most often, stroke is caused by the occlusion of a brain artery. Within the perfusion territory of the occluded vessel, various degrees of necrotic and delayed programmed cell death will occur if the occlusion persists, leading to expanding tissue damage.

    Abstract : The woody tissues serve to stabilise plants, store nutrients and translocate water and minerals. The formation of wood, or ’secondary xylem’, follows a well-defined developmental gradient which is initiated by cell division activity in the vascular cambium. READ MORE

  6. 14. Molecular mechanisms of cell death and cell clearance

    Author : Katharina Klöditz; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Programmed cell death (PCD) is a naturally occurring event in multicellular organisms. It is part of the development as well as ensuring tissue homeostasis and cellular turnover. READ MORE

  7. 15. Biogenesis, function and regulation of the type III secretion translocon of Yersinia pseudotuberculosis

    Author : Salah I. Farag; Matthew S Francis; Jörgen Johansson; Åke Forsberg; Luís Jaime Mota; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yersinia pseudotuberculosis; type III secretion system; translocation; translocon; regulation; bacteria-eukaryotic cell contact; cytokine profiling;

    Abstract : Many Gram negative bacteria use type III secretion systems to cross-talk with eukaryotic cells. Type III secretion system assembly and function is tightly regulated. READ MORE
