Aging is accompanied by remodeling of the immune system. With time, this leads to a decline in immune efficacy, resulting in increased vulnerability to infectious diseases, diminished responses to vaccination, and a susceptibility to age-related ...

Extracellular matrix metalloproteinases (MMPs) are a group of proteins that activate substrates by enzymatic cleavage and, on the basis of their activities, have been demonstrated to play a role in ageing.

Immunosenescence of ageing [PDF]
AbstractAgeing is a complex process that negatively impacts the development of the immune system and its ability to function. The mechanisms that underlie these age‐related defects are broad and range from defects in the haematopoietic bone marrow to defects in peripheral lymphocyte migration, maturation and function.

Myocardial Ischemia and Reperfusion Leads to Transient CD8 Immune Deficiency and Accelerated Immunosenescence in CMV-Seropositive Patients [PDF]
Rationale: There is mounting evidence of a higher incidence of coronary heart disease (CHD) in cytomegalovirus (CMV) seropositive individuals. Objective: The aim of this study was to investigate whether acute MI triggers an inflammatory T-cell ...

A dose-ranging study in older adults to compare the safety and immunogenicity profiles of MF59®-adjuvanted and non-adjuvanted seasonal influenza vaccines following intradermal and intramuscular administration [PDF]
Strategies to optimize responses to seasonal influenza vaccination in older adults include the use of adjuvants, higher antigen doses, and intradermal delivery.

Immunosenescence and cancer [PDF]
Age is a major risk factor for many cancers. Although this is usually viewed in the context of the cell biology, we argue here that age-associated changes to immunity may also contribute to the age-associated increasing incidence of most cancers. This is because cancers are immunogenic (at least initially), and the immune system can and does protect ...

Caenorhabditis elegans and probiotics interactions from a prolongevity perspective [PDF]
Probiotics exert beneficial effects on host health through different mechanisms of action, such as production of antimicrobial substances, competition with pathogens, enhancement of host mucosal barrier integrity and immunomodulation.

Senescent cells were recently shown to play a role in aging-related malfunctions and pathologies. This consensus has been facilitated by evidence from senolytic model mice capable of eliminating senescent cells in tissues using well-characterized ...

Evolution of the G+C content frontier in the rat cytomegalovirus genome [PDF]
Within the 230138 bp of the rat cytomegalovirus (RCMV) genome, the G+C content changes abruptly at position 142644, constituting a G+C content frontier. To the left of this point, overall G+C content is 69.2%, and to the right it is only 47.6%.

Global research trends of immunosenescence: A bibliometric study
Background: Immunosenescence, an age-related deficit in immunity, associated with multiple disorders and making the successful aging a challenge. Although nearly 4000 articles have been published, only few review articles have summarized the research ...
