Possible discovery of mechanism behind mysterious COVID-19 symptoms

The immune system can affect the SARS-CoV-2 spike protein, leading to the production of a misfolded spike protein called amyloid. A new study points to a possible connection between harmful amyloid production and symptoms of COVID-19.

Master’s programme in protein science now open for international students

Linköping University will open its Protein Science master’s programme to international students starting next year. The programme combines theoretical and practical components, with a heavy emphasis on laboratory work.

Alzheimer plaque affects different brain cells differently

Amyloid beta, a protein linked with Alzheimer's disease, has different properties in different cell types in the brains of fruit flies, according to a new study. It seems that certain cell types are hardly damaged at all by amyloid aggregates.

Organisation

Chemistry (KEMI)

The division's research is being performed in the areas of biochemistry, molecular biotechnology, organic chemistry, analytical chemistry, chemical engineering, inorganic chemistry and in physical chemistry, especially computational chemistry.
