Ss disease cause deficits in olfaction, however it is currently unknown how natural and pathological aging impact the detection of social odors which might contribute to the impoverishment of social behavior at old age further worsening overall health. In particular at neuronal level the altered function of cell cycle proteins may affect synaptic plasticity rather than cell duplication.Normal aging and many age-related disorders such as Alzheimer’ It is possible that p53 conformers may occur in the presence of misfolded molecules such as, but not limited to, beta amyloid. Moreover we found that the tertiary structure of p53 and the sensitivity to p53-dependent apoptosis are affected by low concentrations of soluble beta amyloid, the peptide that accumulates in AD brain but also present in peripheral tissues. As a result of such conformational change, p53 partially loses its activity and may become unable to properly activate an apoptotic program when cells are exposed to a noxious stimulus. Within this reference frame we studied p53 in aged controls and demented patients finding that with aging there is an increase of mutant like conformation state of p53 in peripheral blood cells, which is more pronounced in AD patients. The paper is mainly focused on one of such proteins, p53 which has been recently shown to be involved in aging and Alzheimers Disease (AD).

Aging in higher animals may be influenced by the balance of cell survival versus death, a decision often governed by checkpoint proteins in dividing cells. Aging, dementia and cancer share a critical set of altered cellular functions in the response to DNA damage, genotoxic stress, and other insults.

The latter two are the major contributors to illness burden for the aged. Altered response to drugs, cardiovascular and metabolic alterations, cancer and dementia are among the age associated ailments.
