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

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

   Sammanfattning : 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.

3. 2. Ultraviolet radiation and cornea

   Författare :Alexander Podskochy; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cornea; UVR; keratocytes; apoptosis; Fas ligand; hyaluronan; biglycan; rabbit; wound healing.;

   Sammanfattning : Background: Acute exposure of the mammalian eye to UVR results in development of photokeratitis after a period of a few hours. Chronic exposure to UVR is associated with an increased risk of several corneal disorders, including pterygium, climatic droplet keratopathy, and climatic proteoglycan stromal keratopathy. LÄS MER

4. 3. Corneal stromal cell responses to traumatic wounds and topical treatments

   Författare :Marina Kulikovska; Per Fagerholm; Neil Lagali; Anders Behndig; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Background. The cornea has unique anatomic, cellular, molecular, and functional features that lead to important mechanistic differences in the process of repair in comparison with what occurs in skin and other organs. The first observable stromal response in corneal wound healing is keratocyte apoptosis. LÄS MER

5. 4. The multifunctional GAP protein YopE of Yersinia is involved in effector translocation control and virulence

   Författare :Elin Isaksson; Hans Wolf-Watz; Joseph Barbieri; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Yersinia; T3SS; YopE; GAP activity; translocation control; virulence; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

   Sammanfattning : The Gram-negative bacterium Yersinia pseudotuberculosis employs a type 3 secretion system (T3SS) to establish infections. The T3SS translocates a diverse set of effector proteins directly into the host cells. LÄS MER

7. 5. Experimental studies of corneal neovascularisation

   Författare :Branka Samolov; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The cornea contains no vessels, which is a prerequisite for the maintenance of its transparency. Vessel ingrowth leads to opacification resulting in visual impairment, sometimes complete blindness. LÄS MER
