Aging Successfully: The Role of Genetics and Environment in the Era of the Aging-Boom. Potential Therapeutic Implications

2019

Aging is one of the main health-related challenges in the world. The average life expectancy of the global population at birth is increasing up to 72 years, in 2016 and it increases about two years every decade. The healthcare costs in many countries are very high because of the increased number of unhealthy populations, and the consequent increase of severe age-related disabilities [1]. Therefore, the goal of the future should be the achievement of the so-called “health-span” (healthy-life-span), more than the treatment of age-related disease to prevent the collapse of the health system. In order to achieve this objective, it is necessary to identify new targets and biomarkers and to addre…

The role of environmental factors for the onset of restricted mobility outside the home among older adults with osteoarthritis : a prospective cohort…

2017

Objectives The study examines how environmental factors contribute to the onset of restricted mobility outside the home among older adults with osteoarthritis. Methods This is a prospective cohort study of adults aged 50 years and older with osteoarthritis (n=1802). Logistic regression tested the association between the onset of restricted mobility outside the home and health, sociodemographic and perceived environmental barriers (hills and steep slopes, inaccessible public buildings, poor pavement condition, lack of access to public parks or sport facilities, heavy traffic or speeding cars and poor weather). The potential moderating role of environmental barriers on the association between…

Early steps in the European eel (Anguilla anguilla)–Vibrio vulnificus interaction in the gills: Role of the RtxA13 toxin

2015

Vibrio vulnificus is an aquatic gram-negative bacterium that causes a systemic disease in eels called warm-water vibriosis. Natural disease occurs via water born infection; bacteria attach to the gills (the main portal of entry) and spread to the internal organs through the bloodstream, provoking host death by haemorrhagic septicaemia. V.vulnificus produces a toxin called RtxA13 that hypothetically interferes with the eel immune system facilitating bacterial invasion and subsequent death by septic shock. The aim of this work was to study the early steps of warm-water vibriosis by analysing the expression of three marker mRNA transcripts related to pathogen recognition (tlr2 and tlr5) and in…

Wheat amylase trypsin inhibitors drive intestinal inflammation via activation of toll-like receptor 4

2012

Ingestion of wheat, barley, or rye triggers small intestinal inflammation in patients with celiac disease. Specifically, the storage proteins of these cereals (gluten) elicit an adaptive Th1-mediated immune response in individuals carrying HLA-DQ2 or HLA-DQ8 as major genetic predisposition. This well-defined role of adaptive immunity contrasts with an ill-defined component of innate immunity in celiac disease. We identify the α-amylase/trypsin inhibitors (ATIs) CM3 and 0.19, pest resistance molecules in wheat, as strong activators of innate immune responses in monocytes, macrophages, and dendritic cells. ATIs engage the TLR4–MD2–CD14 complex and lead to up-regulation of maturation markers a…

LRP1 modulates APP trafficking along early compartments of the secretory pathway

2008

The amyloid beta peptide (A beta) is a central player in Alzheimer's disease (AD) pathology. A beta liberation depends on APP cleavage by beta- and gamma-secretases. The low density lipoprotein receptor related protein 1 (LRP1) was shown to mediate APP processing at multiple steps. Newly synthesized LRP1 can interact with APP, implying an interaction between these two proteins early in the secretory pathway. We wanted to investigate whether LRP1 mediates APP trafficking along the secretory pathway, and, if so, whether it affects APP processing. Indeed, the early trafficking of APP within the secretory pathway is strongly influenced by its interaction with the C-terminal domain of LRP1. The …

Serving God in a largely theocratic society: rivalry and cooperation between Church and King

2009

Theocracy may be understood in different ways. The meaning mostly used is government by priesthood but we may call that “ecclesiocracy” or “hierocracy.” Here, theocracy will designate government according to God’s prescriptions and wishes—with the specification that the implementation or satisfaction of these prescriptions and wishes should be a public or political rather than a private affair and should involve some degree of coercion. The two meanings are different notably because, in the second, priests need not be the ones, or the only ones, who rule on God’s behalf.

Consensus guidelines for the detection of immunogenic cell death

2014

Apoptotic cells have long been considered as intrinsically tolerogenic or unable to elicit immune responses specific for dead cell-associated antigens. However, multiple stimuli can trigger a functionally peculiar type of apoptotic demise that does not go unnoticed by the adaptive arm of the immune system, which we named "immunogenic cell death" (ICD). ICD is preceded or accompanied by the emission of a series of immunostimulatory damage-associated molecular patterns (DAMPs) in a precise spatiotemporal configuration. Several anticancer agents that have been successfully employed in the clinic for decades, including various chemotherapeutics and radiotherapy, can elicit ICD. Moreover, defect…

ASSOCIATION BETWEEN HELYCOBACTER PYOLRI INFECTION AND PATHOLOGICAL ORAL MANIFESTATIONS

2016

DATA FROM LITERATURE ARE CONTROVERSAL REGARDING THE PRESENCE OF bELICOBACTER PYLORI (HP) IN DENTAL PLAQUE AND ITS ASSOCIATION WITH GASTRIC INFECTION. oNE OF THE POSSIBLE MECHANISMS SUGGETSED FOR RE-INFECTION IS THE RECOLONIZATION WITH HP DENTAL PLAQUE. THE PURPOSE OF THIS REVIEW WAS TO DETERMINE WHETHER DENTAL PLAQUE, POOR ORAL HYGIENE, AND PERIODONTAL DISEASE WERE RISK FACTORS FOR HP INFECTION.

Direct Toll-Like Receptor-Mediated Stimulation of Hematopoietic Stem and Progenitor Cells Occurs In Vivo and Promotes Differentiation Toward Macropha…

2012

Abstract As Toll-like receptors (TLRs) are expressed by hematopoietic stem and progenitor cells (HSPCs), they may play a role in hematopoiesis in response to pathogens during infection. We show here that TLR2, TLR4, and TLR9 agonists (tripalmitoyl-S-glyceryl-L-Cys-Ser-(Lys)4 [Pam3CSK4], lipopolysaccharide [LPS], and CpG oligodeoxynucleotide [ODN]) induce the in vitro differentiation of purified murine lineage negative cells (Lin−) as well as HSPCs (identified as Lin− c-Kit+ Sca-1+ IL-7Rα− [LKS] cells) toward macrophages (Mph), through a myeloid differentiation factor 88 (MyD88)-dependent pathway. In order to investigate the possible direct interaction of soluble microorganism-associated mol…
