Abstract
Oligomer Aβ is the term utilized for multimeric but non-fibrillar forms of amyloid β-protein (Aβ). The most prominent property of oligomer Aβ is considered to be its solubility and structure. Here, we examined the histochemical localization of oligomer Aβ in AD brains. At present, little information is available on the structure and function of cerebral oligomer Aβ. We therefore studied the molecular localization of oligomer Aβ using a newly generated polyclonal mouse antisera against a variant Aβ with a deletion mutation of the 22nd glutamate that we found recently in a patient with familial Alzheimers disease. Intracellular as well as extracellular oligomer Aβ are herein discussed to define their structure and pathological roles in disease.

Diagnostic and therapeutic biomarkers of dementia
Dementia affects 18 million people worldwide. Dementia is a syndrome of symptoms caused by brain disease, usually chronic or progressive, clinically characterized by multiple impairments of higher cortical functions such as memory, thinking, orientation, and learning. In addition, in the course of dementia, cognitive deficits are observed, which often hinder ...read more
