11. Risk factors and comorbidity in primary Sjögren’s syndrome
Sammanfattning : Primary Sjögren’s syndrome is an autoimmune disease, in which the immune system targets the exocrine glands. The disease is characterized by inflammation and dysfunction of the salivary and lacrimal glands, leading to dry eyes and mouth. The etiopathogenesis of autoimmune diseases is not entirely known.

12. Interplay between mitochondria, primary cilium, diabetes and its complications
Sammanfattning : Diabetes is one of the major health problems of the 21st century. Dysfunction of the insulin secreting pancreatic β-cell together with insulin resistance is central to the pathogenesis of type 2 diabetes mellitus (T2DM). The cause of the disease and the underlying mechanisms linking hyperglycemia to diabetes complications are still unclear. LÄS MER
13. Modulation of AMPA glutamate receptor functions in primary neuronal cultures
Sammanfattning : Primary neuronal cultures were used to investigate the properties of AMPA receptors and functional consequences of their activation, as well as AMPA receptor desensitization and possibilities for its modulation. We established the presence and spontaneous functional activity of AMPA receptors in cerebellar granule and cortical cell cultures. LÄS MER
14. Mechanisms for the Influence from Ice Nucleus Aerosols on Clouds and their Indirect Effects: Cloud Modelling
Sammanfattning : The role of multiple groups of primary biological aerosol particles (PBAPs) as ice nucleating particles (INPs), and of ice formation processes such as time-dependent freezing of various INPs, and various secondary ice production(SIP) mechanisms in overall ice concentration has been evaluated in a range of cloud systems by simulating them numerically with the state-of-the-art ‘Aerosol-Cloud’ (AC) model in a 3D mesoscale domain. Also, the mechanismsof aerosol indirect effects (AIEs) arising from anthropogenic INPs, and the responses to these AIEs from time-dependent INP freezing and SIP processes are investigated in the simulated clouds.

15. Germinal centers : why and why not? The humoral response in primary immunodeficiency
Sammanfattning : An efficient and regulated immune system is required for protection against pathogens. B cells are required for a humoral response. For a sustained humoral response against pathogens germinal center (GC) reactions are required. In the GC reaction, B cells with antigen-specific B cell receptors are selected and expanded. LÄS MER
