1. Mining the transcriptome - methods and applications
Sammanfattning : Regulation of gene expression occupies a central role in the control of the flow of genetic information from genes to proteins. Regulatory events on multiple levels ensure that the majority of the genes are expressed under controlled circumstances to yield temporally controlled, cell and tissue-specific expression patterns.

2. Chemokines and their role in dopaminergic development
Sammanfattning : The main pathological hallmark in Parkinson s disease (PD) is the progressive loss of dopaminergic (DA) neurons in the substantia nigra (SN), affecting movements such as walking, talking and writing. Today, there is no cure available for PD and existing treatments only provide symptomatic relief, but the prospect of using stem cell based cell replacement therapies for patients with PD have provided new optimism.

3. PDGFB and P53 in brain tumorigenesis
Sammanfattning : Glioblastoma is the most common, and malignant form of brain tumor. It is characterized by a rapid growth and diffuse spread to surrounding brain tissue. The cell of origin is still not known, but experimental data suggest an origin from a glial precursor or neural stem cell. LÄS MER
4. Generation of cells for cell-replacement therapy: Specification of neural precursors in vivo and in neural stem cell cultures
Sammanfattning : Cell replacement therapy of neurodegenerative disorders aims to substitute the degenerating cells with new functional neurons. Clinical trails with patients suffering from Parkinson’s or Huntington’s disease have generated proof-of-principle results that neural precursors taken from the developing human brain can survive upon grafting to the diseased brain and provide long-lasting symptomatic relief.

5. Generation of midbrain dopaminergic neurons in vivo and in vitro: the role of Neurogenin2
Sammanfattning : Parkinsons disease (PD) is a neurodegenerative disorder where dopaminergic neurons of the substantia nigra (SNc) in the mesencephalon are progressively eliminated. The ensuing loss of dopaminergic innervation of the basal ganglia manifests itself as severe motor deficits in PD patients. LÄS MER
