Mutated tau, amyloid and neuroinflammation in Alzheimer disease—A brief review

This review discussed the importance of mutated tau, amyloid and neuroinflammatory factors and microglia in Alzheimer disease. In particular tau, CD4 and TNF alpha were included in the review and the colocalizations of these factors were highlighted. It is important to realize the Alzheimer disease may result from the interactions of these factors. Some of these factors may coexist at the same region and at the same time e.g. mutated tau and amyloid in plaques. A summary scheme of etiology leading to the disease was included.
