2. 1. Molecular Studies of Mast Cell Migration and Apoptosis : Two Ways of Regulating Mast Cell Numbers at Sites of Inflammation

   Author : Jessica Alfredsson; Gunnar Nilsson; Hans-Uwe Simon; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pathology; mast cell; SCF; IL-3; FcεRI; migration; apoptosis; Bim; Bcl-2; Bcl-XL; Akt; FOXO; MAPK; Patologi; Pathology; Patologi;

   Abstract : Upon activation mast cells release numerous proinflammatory mediators. With this feature, mast cells play an important role in host defense against pathogens, and are involved in tissue remodeling and wound healing. However, in cases of excessive inflammation the effects of mast cells are detrimental. READ MORE

4. 2. Tissue Factor Biological Functions : Coagulation Activity in Microparticles and Signaling with Focus On Migration and Apoptosis

   Author : Mikael Åberg; Agneta Siegbahn; Carl-Henrik Heldin; Teet Velling; Björn Dahlbäck; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue factor; Apoptosis; Migration; Chemotaxis; Simvastatin; Platelet Derived Growth Factor; Cell Signaling; Microparticles; Prostasomes; Trombosis; Coagulation; Prostate Cancer; Breast Cancer; Caspase-3; Caspase-8; NFkappaB; PAR2; Transactivation; Monocytes; Clinical chemistry; Klinisk kemi;

   Abstract : Background: Tissue factor (TF) is a 47 kDa transmembrane glycoprotein known as the main initiator of blood coagulation. TF is over-expressed on many malignant cells and apart from increasing the risk of thrombosis, the presence of TF/FVIIa also promotes the progression of cancer and metastasis by intracellular signaling.

5. 3. Neuropeptides and neurotransmitters in keratocytes : importance in corneal wound healing processes

   Author : Marta Sloniecka; Patrik Danielson; May Griffith; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; substance P; acetylcholine; migration; proliferation; apoptosis; corneal stroma;

   Abstract : Background: The cornea is the outermost transparent layer of the eye and it is responsible for the majorityof the eye’s total focusing power. Keratocytes are the resident cells of the corneal stroma and their function isto produce extracellular matrix components and to take part in corneal healing after injury, which may occurdue to trauma, infection or surgery.

6. 4. Endothelial-leukocyte interactions

   Author : Maria Olofsson; Diabetes - öpatofysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Histology; endothelial cell; leukocyte; apoptosis; mitochondria; heparin binding protein; vascular permeability; E-selectin; migration; rolling; cytochemistry; histochemistry; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur;

   Abstract : This thesis describes early inflammatory responses involving interactions between leukocytes and the endothelial lining of the blood vessel wall. An adhesion molecule, E-selectin, which is upregulated on interleukin-1 activated endothelium, was found to mediate rolling between leukocytes and endothelial cells in vivo. READ MORE

7. 5. The role of Smad7 and TRAF6 in Prostate Cancer Cell Invasion, Migration and Survival

   Author : Maria Ekman; Marene Landström; Carl-Henrik Heldin; Jonas Fuxe; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-beta; cell migration; invasion; apoptosis; Smad7; APC; ATM; TRAF6; p53; PC3U; Medical Cell Biology; Medicinsk cellbiologi;

   Abstract : Transforming growth factor (TGF) β is a tumor suppressor during early tumor development, by inhibiting proliferation and inducing apoptosis. At later stages of cancer, it becomes a tumor promoter, and promotes tumor cell migration and invasion. TGFβ signals via its type II and type I receptors to several downstream signaling pathways.
