  2. 2. Computational Modelling of Early Olfactory Processing

    Author : Malin Sandström; Anders Lansner; Jeanette Hällgren Kotaleski; Thomas Nowotny; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; olfaction; olfactory system; olfactory bulb; olfactory receptor neuron; synchronization; CaMKII; mathematical modelling; lukt; luktsystemet; luktbulben; synkronisering; CaMKII; matematisk modellering; Computer science; Datavetenskap;

    Abstract : Chemical sensing is believed to be the oldest sensory ability. The chemical senses, olfaction and gustation, developed to detect and analyze information in the form of air- or waterborne chemicals, to find food and mates, and to avoid danger. READ MORE

  3. 3. The Role of miRNA in Neurogenesis and Cell Specification

    Author : Malin Åkerblom; Molekylär neurogenetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; miRNA; microRNA; miR-124; miR-9; miR-125; adult neurogenesis; neural stem cells; cell specification; microglia; lentiviral vectors; olfactory bulb; olfactory bulb interneurons;

    Abstract : Only a few decades ago, it was generally believed that gene expression was controlled in a unidirectional way, i.e. DNA was transcribed into RNA, which simply acted as a messenger molecule used to produce the protein that executed cellular functions. READ MORE

  4. 4. Regulatory mechanisms in olfactory system assembly and function

    Author : Carolyn Marks; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The mammalian sense of smell relies on the detection of odorants by a large family of G protein coupled receptors, encoded by ~1300 different genes in mice (Buck and Axel, 1991; Zhang et al., 2007). These odorant receptors (ORs) are expressed in olfactory sensory neurons (OSNs) in the main olfactory epithelium (MOE). READ MORE

  5. 5. The Regulatory Role of microRNAs in the Mouse and Human Brain

    Author : Rebecca Petri; Molekylär neurogenetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microRNA; Argonaute; AGO-RIP; let-7; miR-125; adult neurogenesis; olfactory bulb; autophagy; transposable elements; LINE-2; Huntington’s disease;

    Abstract : microRNAs (miRNAs) are 20-24 nucleotides small, single-stranded, non-coding RNAs. They associate with Argonaute (AGO) proteins and exert their function by inhibition or degradation of messenger RNAs. READ MORE
