Oil induced autoimmune arthritis

We here present evidence that a novel class of genes encoding regulatory leukocytereceptors may be of clinical importance in autoimmune diseases elicited by environmental exposure to immunoadjuvants, in particular mineral oils. The evidence is based on th e structural identification of the rat Oi...

The early stages of adaptive divergence: the speed of evolution

In this proposed project we will study processes during the early phase of adaptive divergence. Lesjaskogsvatnet was colonized by grayling Thymallus thymallus in 1880 and during 120 years more than 20 demes have been established. Owing to profound tempera ture differences among tributaries, we ex...

Astrocytes - guardians of neuroprotection

Astrocytes are the most abundant cell type in the human cerebral cortex but the focus on these cell types have been far neglected. In the later years it has become apparent that they play important roles in the homeostasis of the brain and evidence now al so suggests that they are essential compo...

A novel signal transduction pathway regulating cell separation processes in plants - the IDA/IDL network and their predicted partners.

Signaling mediated by small peptides is important in cell-to-cell communication. Few peptide ligands involved in cell signaling are known from plants and even less is known about the peptide-ligand-receptor pairs. A group of small putative peptide-ligands have recently been characterized by the ...

Study of cellular distribution and biological functions of neonatal Fc receptor in immune cells

Immunoglobulin G (IgG) is the major class of immunoglobulins and the protein with the longest serum half-life. IgG is also actively transferred to the fetus, giving the full-term fetus IgG levels over maternal levels and protective immunity. The MHC class I related neonatal Fc receptor (FcRn) is...

The role of normal neighbouring keratinocytes and fibroblasts on clonal expansion of oral cancer (stem) cells

Recent studies, including ours, have shown that the invasive behaviour of cancer cells is not solely due to mechanisms intrinsic to the individual tumour cell. Genetic changes of individual cells in a specific tissue are not sufficient for invasive cancer to develop. Rather, there is a vivid cro...
