  1. 21. Beyond AMPA and NMDA: Slow synaptic mGlu/TRPC currents : Implications for dendritic integration

    Författare :Marcus Petersson; Erik Fransén; Abdel El Manira; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transient receptor potential; TRP; metabotropic glutamate receptor; mGlu1 5; dendritic integration; synaptic activation; temporal summation; low-frequency; entorhinal cortex; mathematical model; computational neuroscience; Computer science; Datavetenskap;

    Sammanfattning : In order to understand how the brain functions, under normal as well as pathological conditions, it is important to study the mechanisms underlying information integration. Depending on the nature of an input arriving at a synapse, different strategies may be used by the neuron to integrate and respond to the input. LÄS MER

  3. 22. Development of novel serotonin 5-HT6 and dopamine D2 receptor ligands and MAO A inhibitors - Synthesis, structure-activity relationships and pharmacological characterization

    Författare :Cecilia Mattsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dopamine D2 receptor; serotonin reuptake transporter; monoamine oxidase; 5-HT6 receptor; DOPAC; 5-HIAA; 3-tetrahydropyridine indole; 3-piperidine indole; 3- pyrrolidin-1-ylmethyl chromen-2-one; dopamine D2 receptor;

    Sammanfattning : It is known since the 1950s that enhancement of the levels of the monoamines dopamine (DA), serotonin (5-hydroxytryptamine, 5-HT) and norepinephrine (NE) in the brain will relieve the symptoms of major depression, and current therapies are still based on this mechanism. However, all available antidepressants today are still suffering from slow onset of therapeutic action, as well as adverse effects and lack of efficacy. LÄS MER

  4. 23. Transmigration of Toxoplasma gondii across biological barriers

    Författare :Emily C. Ross; Antonio Barragan; Ildiko Rita Dunay; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Apicomplexa; blood-brain barrier; leukocyte; immune cell; transendothelial migration; cell adhesion molecule; host-pathogen; FAK; integrin; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Toxoplasma gondii is an obligate intracellular parasite that can likely infect all warm-blooded vertebrates, with estimates of up to 30% of the global human population being infected. Although infection with T. gondii is usually asymptomatic or mild, in immunocompromised individuals infection can lead to lethal toxoplasmic encephalitis. LÄS MER

  7. 25. Pharmacological Modulation of Skeletal Homeostasis

    Författare :Niklas U. Andersson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Farmakologi; toxicology; farmakognosi; farmaci; toxikologi; pharmacy; pharmacognosy; Pharmacological sciences; peripheral quantitative computed tomography.; dual energy X-ray absorptiomenty; estrogen; parathyroid hormone; gastrectomy; alendronate; ovariectomy; Bone;

    Sammanfattning : Both ovariectomy (OVX) and gastrectomy (GX) cause osteopenia in several animal species including humans. While the effect of OVX has been ascribed to estrogen deficiency, the underlying mechanism behind GX-induced osteopenia is poorly understood. LÄS MER
