PG - 139-42 LID - 10.1016/j.neulet.2008.09.044 [doi] AB - Tumor necrosis factor-alpha (TNF-alpha) is a pro-inflammatory cytokine that plays an important role in the inflammatory process that can be observed in Alzheimer's disease (AD) brain. Different functional promoter polymorphisms within genes modulating inflammation have been demonstrated to elevate the AD risk; thus, we studied five common variations within the promoter region of the TNF-alpha gene in 609 subjects (253 AD patients and 356 controls). No positive associations were found, confirming the greater part of previous studies. Moreover, we also investigated the combined haplotypes of the five different polymorphisms without finding a positive association. Thus, the present investigation does not support the proposal that common nucleotide variations in the TNF-alpha gene can influence the development of AD at least in Italian population.
