Sammanfattning : Intensive management and loss of natural disturbance dynamics in boreal forests leads to habitat loss and degradation for forest dwelling species. As a consequence, many species have become threatened, especially those dependent on dead wood. LÄS MER
Sammanfattning : Interplay between adhesion molecules and the cytoskeleton is involved in many aspects of B lymphocyte behaviour during an immune response. Events such as cell polarisation and locomotion, collaboration with T lymphocytes and segregation in secondary lymphoid tissues all include mechanisms that recognise microenvironment and accordingly adjust morphological features of the cell. LÄS MER
Sammanfattning : The larva of the fruit fly Drosophila melanogaster is an excellent model to study the molecular control of innate cellular immune responses. Cellular responses take place, and can be studied, following infestation of the wasp Leptopilina boulardi. This response includes proliferation and activation (differentiation) of the blood cells (hemocytes). LÄS MER
Sammanfattning : The immune system is a complex network of cells and molecules interacting to preserve the integrity and survival of the host by distinguishing self from non-self, and dysregulation of immune cells can lead to immunodeficiency, autoimmunity, and cancer. The cytoskeleton is essential for several important immune cell functions, including proliferation, movement, signaling, and vesicle trafficking. LÄS MER
Sammanfattning : Drosophila melanogaster has been widely used as a model organism to study the immune responses against bacteria, fungi, parasites and viruses. Here, I present a D. melanogaster virus as a model to study persistent virus infections. I have discovered and characterized the Nora virus, a small picorna-like RNA virus able to persistently infect D. LÄS MER
