Neurodegenerative diseases such as Alzheimer's disease (AD) can be understood in the context of the aging of neuroimmune communication. Although the contribution to AD of the immune cells present in the brain is accepted, the role of the peripheral immune system is less well known. The present review examines the behavior and the function and redox state of peripheral immune cells in a triple‐transgenic mouse model (3×Tg‐AD). These animals develop both beta‐amyloid plaques and neurofibrillary tangles with a temporal‐ and regional‐specific profile that closely mimics their development in the human AD brain. We have observed age and sex‐related changes in several aspects of behavior and immune cell functions, which demonstrate premature aging. Lifestyle strategies such as physical exercise and environmental enrichment can improve these aspects. We propose that the analysis of the function and redox state of peripheral immune cells can be a useful tool for measuring the progression of AD.
