Researchers at ETH Zurich have identified a proteomic signature that could recognize long COVID six months after acute infection. Biologically, the signature indicated that the complement system remained active in patients with long COVID six months after infection. Translationally, it could lead to a diagnostic test for long COVID, and suggests that targeting the complement system could be a therapeutic approach to prevent or treat the disorder.

Alzheimer’s disease (AD) can be divided into five distinct subtypes based on protein expression levels measured in the cerebrospinal fluid (CSF). The subtypes were associated with different genetic risk factors and are likely to benefit from different treatment approaches. Many clinicians, drug developers and the general public still “think of Alzheimer’s as a single disease entity, and that suggests that every patient needs to have the same medication,” Betty Tijms told BioWorld.
