1. It Takes Two to Tango : Bacterial heterogeneity and host cell features govern Salmonella infection
Sammanfattning : Salmonella enterica serovar Typhimurium (S.Tm) causes enterocolitis with significant worldwide morbidity and mortality. The general aim of this thesis is to investigate variation in host cell invasion mechanisms used by S.Tm across different host cell contexts, as well as the influence of bacterial cell-cell heterogeneity on invasion-relevant S.

Sammanfattning : The aim of the present thesis was to study how the neuropeptide galanin affects the neurochemistry and functional activity of the cholinergic septohippocampal projection, which plays a pivotal role in learning and memory. This cholinergic system is strongly impaired in Alzheimer's disease and in age-related dementias. LÄS MER
3. Visually guided swimming in box jellyfish: A study of swimming behaviour in response to visual stimuli
Sammanfattning : Most animals use eyes to guide their behaviour. Analysing, and understanding, visually guided behaviours gets more complicated the more advanced the animal gets. Box jellyfish provide a relatively simple system for understanding visually guided behaviours. LÄS MER
Sammanfattning : Several studies suggest profound effects on mood and cognition by neuroactive steroids. Estrogen alone or in combination with antidepressant drugs affecting the serotonin system has been used to treat mood disorders. On the other hand, progesterone is related to negative effects on mood and memory. LÄS MER
Sammanfattning : Pattern-recognition receptors (PRRs) include the cell surface or endosomal membrane localized Toll-like receptors (TLRs) and the cytoplasmic PRRs such as RIG-I-like receptors (RLRs), NOD-like receptors (NLRs) and cytoplasmic DNA receptors (CDRs). Triggering of PRRs culminates in the transcriptional induction of pro-inflammatory cytokines and type I interferons (IFNs) that coordinate protection against pathogens but require tight control to avert inflammatory diseases.
