The emerging role of Notch pathway in ageing: Focus on the related mechanisms in age-related diseases
2016
Notch signaling is an evolutionarily conserved pathway, which is fundamental for the development of all tissues, organs and systems of human body. Recently, a considerable and still growing number of studies have highlighted the contribution of Notch signaling in various pathological processes of the adult life, such as age-related diseases. In particular, the Notch pathway has emerged as major player in the maintenance of tissue specific homeostasis, through the control of proliferation, migration, phenotypes and functions of tissue cells, as well as in the cross-talk between inflammatory cells and the innate immune system, and in onset of inflammatory age-related diseases. However, until …
Thinking of future as an older individual increases perceived risks for age‐related diseases but not for COVID‐19
2022
Actively thinking of one's future as an older individual could increase perceived risk and risk aversion. This could be particularly relevant for COVID-19, if we consider the common representation of the risk of being infected by COVID-19 as associated with being older. Increased perceived risk could bear consequences on the adoption of preventive behaviours. Thus, we investigated whether increasing the salience of individuals' future as an older adult would impact on their perceived risk for COVID-19 and medical conditions varying for age-relatedness. One hundred and forty-four Italian adults (Mage = 27.72, range: 18–56) were randomly assigned to either a future as older adult thinking or …
Ageing, longevity, exceptional longevity and related genetic and non genetics markers: panel statement
2018
In May 2012, a group of scientists and clinicians met in Athens (Greece) to consider the relevance of ageing, longevity, exceptional longevity and related genetic and non genetic markers. During this meeting, we firstly reviewed recent epidemiological and clinical studies on ageing, longevity and exceptional longevity, briefly analysed the ageing theories and discussed successful and unsuccessful ageing also taking into account the evolutionary perspective. Secondly, we considered the three phenotypes based on the definition of ageing, longevity and exceptional longevity and the associated biomarkers. Third, we discussed proposed treatments suitable to counteract or slow down ageing. Finall…
Age-Related Inflammation: the Contribution of Different Organs, Tissues and Systems. How to Face it for Therapeutic Approaches
2010
A typical feature of ageing is a chronic, low-grade inflammation characterized by a general increase in the production of pro-inflammatory cytokines and inflammatory markers ("inflamm-ageing"). This status may slowly damage one or several organs, especially when unfavorable genetic polymorphisms and epigenetic alterations are concomitant, leading to an increased risk of frailty together with the onset of age-related chronic diseases. The contribution of different tissues (adipose tissue, muscle), organs (brain, liver), immune system and ecosystems (gut microbiota) to age-related inflammation ("inflamm-ageing") will be discussed in this review in the context of its onset/progression leading …
Gender-Related Immune-Inflammatory Factors, Age-Related Diseases, and Longevity
2010
This review discusses the role of estrogens as pro- or antiinflammatory players in immune-inflammatory responses. In particular, their role in Alzheimer’s disease (AD), an example of immune-inflammatory disease, is discussed briefly. AD is a progressive neurodegenerative disease, which in Western societies accounts for the majority of cases of clinical senile dementia. However, sexual dimorphism of diseases may also depend on factors independent of sex hormones (i.e., a gender effect), as demonstrated by our data on differential longevity in females and males. In fact, differences in mortality between men and women are not only a question of sex that refers to biological differences, but ra…
Circulating miRNAs in Successful and Unsuccessful Aging. A Mini-review
2019
Aging is a multifactorial process that affects the organisms at genetic, molecular and cellular levels. This process modifies several tissues with a negative impact on cells physiology, tissues and organs functionality, altering their regeneration capacity. The chronic low-grade inflammation typical of aging, defined as inflammaging, is a common biological factor responsible for the decline and beginning of the disease in age. A murine parabiosis model that combines the vascular system of old and young animals, suggests that soluble factors released by young individuals may improve the regenerative potential of old tissue. Therefore, circulating factors have a key role in the induction of …
Low Grade Inflammation as a Common Pathogenetic Denominator in Age-Related Diseases: Novel Drug Targets for Anti-Ageing Strategies and Successful Age…
2010
Nowadays, people are living much longer than they used to do, however they are not free from ageing. Ageing, an inexorable intrinsic process that affects all cells, tissues, organs and individuals, is a post-maturational process that, due to a diminished homeostasis and increased organism frailty, causes a reduction of the response to environmental stimuli and, in general, is associated to an increased predisposition to illness and death. However, the high incidence of death due to infectious, cardiovascular and cancer diseases underlies a common feature in these pathologies that is represented by dysregulation of both instructive and innate immunity. Several studies show that a low-grade s…
Proceedings of the Symposium “Updates in Pathobiology: Causality and Chance in Ageing, Age-related diseases and Longevity”
2017
The Symposium "Updates in Pathobiology: Causality and Chance in Ageing, Age-related diseases and Longevity" was held on March 24 in Palermo, 2017 (Sala delle Capriate, Palazzo Chiaramonte Steri), the day after exams for obtaining the title of PhD in Molecular Medicine and Biotechnology XXIX, Cycle (Coordinator Prof. Calogero Caruso) by seven PhD candidates; four of them have been awarded the title of Doctor Europaeus.
Endothelial Progenitor Cells A New Real Hope?
2017
Chronic inflammatory diseases, such as cardiovascular diseases (CVDs), diabetes, Alzheimer’s disease (AD) and cancer, have a disproportionate prevalence with advancing age owing to the continuous growth in the aging population. This condition determines several medical, economic and social problems due to the dramatic increase in the number of affected individuals, who are not autonomous. Thus, research efforts are centred around reducing and/or delaying the onset and progression of these diseases by researching new strategies for early prevention and diagnosis. In this context, understanding the mechanisms involved in the tissue, organ protection and repair are imperative for the developme…
