Abstract
Background:
Most of the recent reports suggest that inflammatory mediators play a central
role in the etiopathogenesis of Alzheimer's disease (AD) and that the conditions leading to a chronic
low-grade inflammation, such as stress, depression, obesity and metabolic syndrome, increase the odds
of developing Mild Cognitive Impairment (MCI) and AD. Microglia cells are the main actors in the AD
process: stimuli from the microenvironment may induce microglia cells to switch to a classically activated
inflammatory phenotype M1, or, on the contrary to an alternatively activated M2 phenotype characterized
by the secretion of different types of cytokines. Many attempts are currently being made in
order to delay the progression of AD by reducing inflammatory mechanisms underlying the disease.
Several studies support a relationship among neuroinflammation and nutrients, foods or dietary patterns,
taking into account the synergistic or antagonistic biochemical interactions among nutrients as well as
the different food sources of the same nutrient. Natural antioxidant and anti-inflammatory compounds
found in plant foods, such as fruits, particularly berries (such as strawberry, blueberry, blackcurrant,
blackberry, blueberry and mulberry) have been shown to exert neuroprotective activity. It is still unclear
whether the dietary bioactive compounds enter the Blood Brain Barrier (BBB) playing a direct antiinflammatory
or pro-inflammatory effect on microglia and/or other Central Nervous System (CNS)
cells. Another hypothesis is that they may trigger a peripheral reaction that induce indirectly a CNS' response.
The subsequent synthesis of cytokines may drive microglia polarization by different ways. So,
via an indirect route microglia detects and responds to immune-to-brain signaling.
Conclusion:
This review summarizes current evidence about the potential mechanisms of the interaction
among diet, neuroinflammation and AD.

Abstract
The circulating cells of the immune system are sensitive to environmental contaminants, and effects are often manifested as changes in the cell surface differentiation antigens of affected populations of cells, particularly lymphocytes. In this investigation, we explore the likelihood that variation in the expression of the surface markers of immune cells can be used as an index of exposure to toxic chemicals. We recruited 38 healthy New Jersey men to study pesticides effects: 19 orchard farmers (high exposure); 13 berry farmers (low exposure); and 6 hardware store owners (no exposure). Immunophenotyping was performed assaying the following cell surface antigens: CD2, CD4, CD8, CD14, CD20, CD26, CD29, CD45R, CD56, and PMN. Data were analyzed using univariate and multivariate methods. There were no significant differences among the groups with respect to routine medical histories, physical examinations, or routine laboratory parameters. No striking differences between groups were seen in univariate tests. Multivariate tests suggested some differences among groups and limited ability to correctly classify individuals based on immunophenotyping results. Immunophenotyping represents a fruitful area of research for improved exposure classification. Work is needed both on mechanistic understanding of the patterns observed and on the statistical interpretation of these patterns.

Abstract
Dietary taurine has been shown to protect rat and hamster lung epithelia from acute oxidant injury. One of the earliest morphologic criteria of oxidant injury is the alteration of tight junctions of the peripheral lung airways. In the present study, we have used this criteria to evaluate whether taurine was capable of protecting rat lungs from ozone exposure. Rats were treated for 10 days with 50% taurine in their drinking water, prior to exposure to 2 ppm of ozone for 3 hours. The lungs from rats pretreated with taurine and exposed to ozone were compared to untreated rats exposed to ozone and air-exposed controls. At 2, 6, 12, 24, 48, and 72 hours after exposure to air or ozone, rats were anesthetized and the lungs perfusion-fixed through the right side of the heart with a solution of glutaraldehyde and paraformaldehyde. Light microscopy revealed the typical, mild inflammatory cell infiltrate beginning at 6 hours after ozone exposure in bronchioles, alveolar ducts, and surrounding alveoli which was absent in the lungs of animals treated with taurine. Electron microscopic analysis of thin sections indicated alterations in tight junctions which was confirmed by tracer studies using ruthenium red and lanthanum. Alterations in airway epithelium tight junctions were seen 2 and 6 hours after ozone treatment and only in the 2-hour tissues from animals pretreated with taurine prior to ozone exposure. Freeze-fracture replicas from all exposure groups by electron microscopy revealed that only the 2- and 6-hour groups showed alterations in tight junctions. The alterations were characterized by decreased number of fibrils and breaks in the fibrils. Rats treated with taurine and exposed to ozone exhibited these alterations focally at 2 hours exposure and no changes were noted at 6 hours post ozone exposure. These data confirmed previous findings that injury induced by ozone is transient and that taurine protects the bronchioles from this form of oxidant injury.
