1. 6. Novel Insights into Haematopoietic Stem Cell Regulation and Function

   Författare :Sarah Warsi; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haematopoiesis; Haematopoietic stem cell; Stem cell regulation; Haematopoietic stem cell transplantation;

   Sammanfattning : The haematopoietic stem cell (HSC) is a somatic stem cell essential for life long haematopoiesis; HSCs have the capability to differentiate into all mature types of blood cells and can also undergo self-renewal to maintain their own numbers. They also have the potential to reconstitute a complete haematopoietic system following HSC transplantation, also known as bone marrow transplantation, which is used to treat many haematopoietic disorders.

3. 7. Generating Dendritic Cells by Direct Cell Reprogramming. Merging cellular reprogramming with immunology towards the development of novel cancer immunotherapies

   Författare :Fábio Fiúza Rosa; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dendritic Cell; Direct Cell Reprogramming; Single-cell analysis; Immunotherapy;

   Sammanfattning : Cell fate reprogramming towards pluripotency or alternative somatic cell-types has highlighted the plasticity of adult somatic cells, providing new technologies to generate desired cell types for tissue repair or for disease modeling. There is momentum to bring these concepts to immunology by specifying unique immune cellular identities that set in motion immune responses. LÄS MER

4. 8. Hematopoiesis: Functional Insights by Cell Fate Conversion

   Författare :Martin Wahlestedt; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Blood cell formation, or hematopoiesis, is maintained by rare hematopoietic stem cells (HSCs) residing in the bone marrow (BM). HSCs may self-renew (the process whereby HSCs replicate to produce new HSCs) to preserve their own numbers, as well as initiate a highly coordinated hierarchical differentiation process that results in the production of mature effector blood cells.

5. 9. Exploring Cellular Dynamics : From Vesicle Tethering to Cell Migration

   Författare :Parham Ashrafzadeh; Johan Kreuger; Jonas Fuxe; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; cancer; cell migration; exocyst complex; exocytosis; FGD5; lipid rafts; plasma membrane; receptor trafficking; VEGFR2;

   Sammanfattning : Cells in the body communicate with each other in order to cooperate efficiently. This communication is in part achieved by regulated secretion of signaling molecules, which when released from a cell may activate receptors present at the plasma membrane of an adjacent cell. Such signals affect both cell fate and behavior. LÄS MER

7. 10. Radiation response in human cells : DNA damage formation, repair and signaling

   Författare :Ann-Sofie Gustafsson; Bo Stenerlöw; Andrzej Wojcik; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA damage; DNA repair; DSB; NHEJ; DNA-PK; ionizing radiation; heat-labile sites; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap;

   Sammanfattning : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. LÄS MER
