1. Apoptosis And Excitotoxicity In The Death of Cultured And Grafted Dopaminergic Neurones
Sammanfattning : Over the past two decades, grafting of embryonic nigral tissue has developed into a feasible therapeutic strategy for Parkinson's disease (PD). It has become apparent that the degree of restoration of dopaminergic neurotransmission by the transplanted cells is highly correlated to the symptomatic relief. LÄS MER
2. Oxidant-induced cell death in lymphocytes: mechanisms of induction and resistance
Sammanfattning : Reactive oxygen species (oxidants, oxygen radicals) produced by the phagocytic NADPH oxidase have pivotal roles in immunity. Patients lacking a functional NADPH oxidase suffer from chronic granulomatous disease, which is characterized by recurring bacterial infections and thus manifesting the importance of reactive oxygen species in host defense against bacteria.

3. Gene regulation by different proteins of TGFβ superfamily
Sammanfattning : The present thesis discusses how gene regulation by transforming growth factor β (TGFβ) family cytokines is affected by post-translational modifications of different transcription factors. The thesis also focuses on gene regulation by transcription factors involved in TGFβ signaling. LÄS MER
4. Post-translational modifications in DNA base excision repair : The roles of CK2 and PARP-1
Sammanfattning : Base lesions and DNA single-strand breaks (SSBs) are very common types of DNA damage. The base excision repair (BER) and single-strand break repair (SSBR) machineries both require a succession of enzymatic events in order to remove these types of endogenous lesions and to restore the DNA.

5. Interplay between Transcription and Homologous Recombination in the Presence of DNA Damage
Sammanfattning : The biochemical processes of DNA repair, replication and recombination compete for the same substrate, the DNA molecule. This competition is natural, as each process requires the same template. In order to resolve possible conflicts between these processes, when they take place on a particular stretch of DNA, certain crosstalk is expected. LÄS MER
