After further study of larger numbers of patients, quantifying prostaglandin-d-synthase/transthyretin complex in CSF may be useful in the diagnosis of Alzheimer disease, possibly in the early stages of the disease.
Taken together, we suggest that TTR-MT1/2 complexes may be functionally significant not only in healthy conditions but also in Abeta deposition in Alzheimer disease, thereby providing a novel potential therapeutic target.
To examine the neuroprotective role of TTR, we investigated the conjugated forms of TTR with cysteine (Cys) and cysteinglycine (CsyGly) in the CSF of 39 probable Alzheimer's disease (AD)-affected subjects and in a cohort of subjects without cognitive impairment (27 subjects).
