2. 1. The role of nitric oxide in cytoskeleton-mediated organelle transport and cell adhesion

   Author : Harriet Nilsson; David Sugden; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Nitric oxide (NO) is a signaling molecule that is produced by many different kinds of cells, and it is known to mediate actions such as blood vessel dilation, communication between nerve cells, and killing of bacteria in infections. The cytoskeleton is involved in many important cellular functions, among them intracellular transport of organelles, migration, and cell division. READ MORE

4. 2. Signaling for color change in melanophores : and a biosensor application

   Author : Annika M. Karlsson; Samuel Svensson; Margareta Wallin; Linköpings universitet; []
   Keywords : color change; melanophores; tyrosine; phosphorylations; melatonin; nitric oxide; MEDICINE; MEDICIN;

   Abstract : Melanophores are dark brown pigment cells located in the skin of fish, amphibia, reptiles, and many invertebrates. The color of the animal can change via rearrangement of pigment granules, melanosomes, in the cells. The dark melanophores can either hide colorful cells so that the animal appears dark, or let through colors from underneath. READ MORE

5. 3. Mechanosensing in the vascular wall - the role of cellular microdomains in vascular remodeling

   Author : Sebastian Albinsson; Kärlfysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; tissue culture; Histologi; cytokemi; histokemi; vävnadskultur; cytochemistry; histochemistry; wall stress; shear stress; hypertension; Histology; differentiation; growth; caveolin; smooth muscle; actin; Fysiologi; Cardiovascular system; Kardiovaskulära systemet;

   Abstract : The vascular wall has a remarkable capacity to adapt to mechanical forces exerted by the intraluminal blood pressure and flow. This includes rapid change in contractile tone as well as chronic alteration of vessel structure if the stimulus persists. Stretch of the intact blood vessel wall promotes growth and contractile differentiation. READ MORE

6. 4. Neuronal apoptosis in excitotoxicity : involvement of nitric oxide and cytoskeletal damage

   Author : Emanuela Bonfoco; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : In the nervous system apoptosis may play an important role in the development of several neurodegenerative diseases. The overall objective of the present work is to investigate at the cellular and molecular levels, the mechanisms by which neurons are signaled to undergo apoptotic cell death after exposure to various effectors, such as nitric oxide (NO) and its byproducts, glutamate, and colchicine.

7. 5. On the Regulation of the Epithelial Paracellular Permeability

   Author : Pia Nybom; Janove Sehlin; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : The epithelia of for instance the small intestine(s) plays a crucial role in the vectorial transport of nutrients and other solutes from the lumen to underlying body fluids, i.e. blood and lymph. READ MORE
