1. 1. Mechanisms Underlying the Specification of Definitive Hematopoiesis

   Författare :Rita Alves; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GATA2; mitotic bookmarking; HSC; transcription factors; reprogramming;

   Sammanfattning : Hematopoietic stem cells (HSCs) maintain blood through self-renewal and differentiation. Although HSC transplantation is the only cure for various blood disorders, generating and maintaining HSCs in vitro remains challenging, partly due to a limited understanding of the cellular and molecular mechanisms underlying human HSC ontogeny.

3. 2. Pathways that govern hematopoietic stem cell fate

   Författare :Matilda Billing; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :hematopoies; Hematopoietic stem cell; TGF beta; Smad signaling; GATA2; p57;

   Sammanfattning : Hematopoietic stem cells (HSCs) compose a rare population of undifferentiated cells, residing in the bone marrow of adult individuals, ensuring life-long maintenance and replenishment of the blood system. This fantastic achievement is possible owing to two special characteristics of the HSCs: their ability to make copies of themselves (self-renew), and their capacity to differentiate to all lineages of the blood system.

4. 3. Influence of serotonin-related genes on behavior and body weight

   Författare :Jessica Bah Rösman; Göteborgs universitet; []
   Nyckelord :Serotonin; Genes; anorexia nervosa; premenstrual dysforia; body weight; suicide; polymorphism; HTR2C; SLC6A4; GATA2; HTR3B;

   Sammanfattning : Rationale: The neurotransmitter serotonin has been implicated in the regulation of normal behaviors, including food intake, and attributed importance for a variety of common psychiatric conditions, including major depression, suicidal behavior, eating disorders and premenstrual dysphoria. The purpose of these studies was to explore the possible influence of genetic variation in serotonin-related genes on a) body weight, b) binding capacity of the serotonin transporter in the brain of suicide attempters and c) a disorder for which numerous findings suggest serotonin to play a key role, i.

5. 4. Programming Blood Cell Fates. Insights from Direct Lineage Conversion and Development

   Författare :Sandra Capellera Garcia; Avdelningen för molekylärmedicin och genterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic development; Erythropoiesis; Megakaryopoiesis; Direct Lineage Conversion;

   Sammanfattning : Red blood cells (RBC) and platelets constitute the non-immune branch of the hematopoietic system and are responsible for the vital functions of transporting oxygen to the tissues and clotting blood vessel injuries, respectively. These cells are produced during embryonic development and throughout life through a process called hematopoiesis which is tightly regulated by extrinsic and intrinsic factors. LÄS MER

7. 5. On the influence of serotonin- and sex steroid-related genetic variation on mood, anxiety, personality, autism and transsexualism

   Författare :Susanne Henningsson; Göteborgs universitet; []
   Nyckelord :serotonin; 5-HTTLPR; TPH2; 5-HT3; sex steroids; androgen receptor; estrogen receptor; genetics; gene-gene interaction; social phobia; anxiety; premenstrual dysphoric disorder; depression; personality; autism; transsexualism; amygdala; emotional perception; life events;

   Sammanfattning : Background: The neurotransmitter serotonin has been related to mood and anxiety, and variation in genes that encode important members of the serotonergic system may hence affect mood- and anxiety-related traits. Sex steroids influence brain development, and variation in genes encoding androgen and estrogen receptors, or enzymes needed for sex steroid synthesis, may be of importance for both personality traits and risk for psychiatric disorders.
