Increasing age has been associated with an insufficient protection following vaccination and an increased incidence and severity of infectious diseases. The predicted acceleration of global population aging will accentuate the need to understand the mechanisms that drive the age-related decline of the immune system and to, eventually, identify strategies to lower the burden of infectious diseases in elderly people. One type of immune cell appears to be most dramatically affected by the aging process: T lymphocytes. Age-related changes of the bone marrow and the thymus microenvironment lead to a decreased thymic output of functional, naïve T lymphocytes. As T lymphocytes are key players of the adaptive immune system, this research topic will summarize our current understanding on how aging affects the microenvironmental niches and molecular networks that are important for the generation, survival and function of naïve, memory and effector T lymphocytes. This research topic will also address the impact of aging on the different T lymphocyte lineages, such as regulatory T cells and Th17 cells and how age-related changes of the microenvironment affect organ- and tissue-resident memory T lymphocytes. Eventually, the identification of a set of markers for immunosenescence would facilitate the design and application of more specific therapies and improved vaccines and vaccination strategies for elderly people, thereby increasing life and health span.

This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact

This Special Issue of Cells on “Insulin-Like Growth Factors in Development, Cancers and Aging” provides a collection of modern articles dealing with the role of insulin-like growth factors (IGF1) in cancer biology, aging and development. Featured articles explore basic and clinical aspects of the IGF1 system, including post-genomic analyses as well as novel approaches to target the IGF1 receptor (IGF1R) in oncology. The present Special Issue highlights some of the most important topics in the broad area of IGF research, including the role of IGF1 in aging and longevity, attempts to target the IGF1 axis in oncology, the role of IGF-binding proteins, structural aspects of IGF-II, etc. We trust that this assembly of articles will be of great help to students, basic researchers and practitioners.

Over the last 100 years, the numerous advances in science, the improved sanitary conditions and a decline in poverty have led to an increase in life expectancy. As a result, in the coming years, the number of over-65s will triple, and the over-80s will be the fastest growing portion of the population.However, an increased lifespan is associated with an increase in chronic diseases, such as cardiovascular disease, diabetes, cancer, sarcopenia, and degenerative disorders. Therefore, ideally, increased lifespan should be associated to a better healthspan, which is the period one individual is living in good health.Based on evidence that aging is a multifaceted phenomenon, resulting from one or more failures at the molecular, cellular, physiologic, and functional levels, age-related diseases are difficult therapeutic targets.Data on the correlation between the quality of one’s diet and life expectancy, and the application of calorie restriction regimens, or of micronutrients, antioxidants and functional foods in the diet make nutrition, together with exercise, a natural weapon to combat age-related diseases and improve healthspan.
