2. 1. The effects of plasminogen deficiency on the healing of tympanic membrane perforations

   Author : Annika Hansson; Sten Hellström; Diana Berggren; Tor Ny; Magnus von Unge; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tympanic membrane; macrophages; neutrophils; fibrin ogen ; inflammation; keratinocyte migration; wound healing; uPA; tPA; in vitro; Otorhinolaryngology; Otorhinolaryngologi;

   Abstract : The healing of tympanic membrane (TM) perforations is a complex wound healing process including inflammation, migration of keratinocytes and tissue remodelling. Most TM perforations in human heal spontaneously, however some perforations become chronic, and the reason to why is still largely unknown. READ MORE

4. 2. Exploring immune cell functions and ways to make use of them

   Author : Evelina Vågesjö; Mia Phillipson; Michael Hickey; Uppsala universitet; []
   Keywords : leukocytes; neutrophils; macrophages; regulatory T cells; chemokines; VEGF-A; hypoxia; ischemia; muscle; Islets of Langerhans; diabetes; transplantation; wound healing;

   Abstract : In addition to host defense, alternative functions of immune cells are emerging. Immune cells are crucial during healing of injured tissue, in formation of new blood vessels, angiogenesis, and also in maintaining the balance in inflammation having immune regulating functions.

5. 3. Macrophages and neutrophils in tissue homeostasis and recovery from ischemic injury

   Author : Kristel Parv; Mia Phillipson; Gustaf Christoffersson; Per-Ola Carlsson; Stephen Jenkins; Uppsala universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; macrophages; neutrophils; hindlimb ischemia; ischemic disease; mural cells; diabetes mellitus; postnatal β cell maturation.;

   Abstract : Neutrophils and macrophages have functions beyond protection against pathogens. The overall aim of the work presented in this thesis was to identify novel tasks for these innate immune cells in maintaining homeostasis. READ MORE

6. 4. Redox effects on neutrophils in wound healing conducted by wound dressings and hyperbaric oxygen

   Author : Herman Sahlin; Göteborgs universitet; []
   Keywords : neutrophil granulocyte; wound healing; wound dressing; reactive oxygen species; NO; hyperbaric oxygen; bacterial killing;

   Abstract : The increased influx of neutrophils into chronic wounds results in increased production of reactive oxygen species (ROS), nitric oxide (NO) and lipid peroxidation products (LPP), as well as a ROS-induced increase in protease levels. The NO and LPP impair the respiratory burst response of the neutrophils and reduce their capacity to kill bacteria and digest debris. READ MORE

7. 5. Inflammation and neutrophil recruitment in healing of colonic anastomosis

   Author : Peter Månsson; Kirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; experimetnal; anastomotic healing; Inflammation; neutrophil redruitment; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi;

   Abstract : Wound healing is a multistep process with an initial inflammatory response, followed by synthesis of extracellular matrix components and finalized by a repair phase. One main goal was to determine the impact and adhesive mechanisms of neutrophil recruitment in anastomotic healing in the colon. READ MORE
