   Sammanfattning : Sex differences in the human body affect many different organs and tissues, some of them have an effect on the human brain and its development. In the developing nervous system, sex differences can bias the number or functionality of neurons, glial cells or synapses. As a result, neural networks might develop with a sex-specific bias.

3. 12. The role of PKC in neuronal differentiation and in regulation of the actin cytoskeleton during neurite outgrowth

   Författare :Ulrika Trollér; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytogenetics; Genetik; cytogenetik; Rho-family; actin cytoskeleton; neurite; differentiation; PKC; regulatory domain; Genetics;

   Sammanfattning : Protein kinase C (PKC) is a family of serine/threonine kinases subgrouped into classical (α, βI, βII, γ), novel (δ, ε, η, θ) and atypical (ζ, ι/λ) isoforms. PKC can be activated by phorbol esters, and prolonged treatment of neuroblastoma cells has been shown to induce neuronal differentiation with neurite outgrowth and increased expression of neuronal genes.

4. 13. Derivation, propagation and differentiation of human stem and progenitor cells

   Författare :Mathilda Zetterström Axell; Göteborgs universitet; []
   Nyckelord :Human embryonic stem cells; neural progenitor cells; stem cells; differentiation; propagation; migration; cell culturing; rostral migratory stream; electrospun scaffolds;

   Sammanfattning : Neuronal loss is a common feature of many neurological disorders, including stroke, Parkinson’s disease, Alzheimer’s disease and traumatic brain injury. Human embryonic stem cells (hESCs) and hESC-derived neural progenitors (NPs) may provide a number of new ways for studying and treating diseases and injuries in the brain. LÄS MER

5. 14. Generation of midbrain dopaminergic neurons in vivo and in vitro: the role of Neurogenin2

   Författare :Elin Andersson; Neurobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; Medicin människa och djur ; cell replacement; Parkinson?s; dopamine; neuronal specification; development; mesencephalon; TH; neuronal differentiation; proneural genes; transcription factors; bHLH; neurospheres; stem cell; progenitor cell;

   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

7. 15. The role of nuclear envelope proteins in chromatin organization, differentiation and disease

   Författare :Cecilia Bergqvist; Einar Hallberg; Philippe Collas; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nuclear envelope proteins; chromatin organization; epigenetics; differentiation; quantitative image analysis; Samp1; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

   Sammanfattning : In eukaryotes the genetic material is separated from the cytoplasm by the nuclear envelope (NE), consisting of the outer and inner nuclear membrane, the nuclear lamina and the nuclear pores. The genetic material is highly structured with transcriptionally inactive heterochromatin enriched at the nuclear periphery and transcriptionally active euchromatin in the nuclear interior.
