Recent Advances in T Cell Signaling in Aging
The immune system of mammalian organisms undergoes alterations that may account for an increased susceptibility to certain infections, autoimmune diseases, or malignancies. Well characterized are age related defect in T cell functions and cell mediated immunity. Although it is well established that the functional properties of T cells decrease with age, its biochemical and molecular nature is...
متن کاملT cell aging
The immune system exhibits profound age-related changes, collectively termed immunosenescence. The most visible of these is the decline in protective immunity, which results from a complex interaction of primary immune defects and compensatory homeostatic mechanisms. The sum of these changes is a dysregulation of many processes that normally ensure optimal immune function. Recent advances sugge...

متن کاملAging of the CD4 T Cell Compartment
Higher morbidity and mortality following infections, particularly influenza, is observed in the elderly population. Because of this, people over 65 years old are often targeted for preventive immunization. Many vaccines, however, are not as effective in generating protective antibodies in older individuals. CD4+ T cells, through their B cell helper functions, play a central role in the humoral ...
متن کاملAging: T cell metabolism within tumors
incidence of cancer increases in the aged partially due to accumulations of genomic mutations, epigenetic dysregulations and the development of chronic inflammatory responses. In US, more than 50% of all cancer cases occur in patients over 65 [1]. Cancer immunotherapy, which has achieved significant breakthroughs in recent years, harnesses the patients' own immune system. However, the immune sy...
