Extracellular Vesicles and Immune System in Ageing and Immune Diseases

Nutrition and Immune System

تداوم سلامتی انسان با سیستم ایمنی بدن مرتبط است. این سیستم از بافتهای متنوع، سلولها و عواملی تشکیل شده است که از بدن در مقابل آنتی ژنهای مضر و پاتوژنها حفاظت می کند. سلولهای ایمنی در زمان وجود عفونت جهت محدود کردن ضایعات سلولی و بافتی، تجمع می یابند. یک شبکه نظارت متشکل از سلولهای ایمنی در تشخیص سلولهای غیر طبیعی عمل می کنند. توانایی بدن در محافظت از خود در برابر عوامل خارجی، بخصوص باکتریها، و...

Ageing and the Immune System

Decreases in immune responsiveness with age are thought to contribute to the increased incidence and severity of infectious disease among the elderly. Several interventions, including exercise, have been proposed to restore immune function in older populations. The findings from some, but not all studies, support the possibility that exercise may attenuate immunosenescence. In recent years, the...

Extracellular Membrane Vesicles and Immune Regulation in the Brain

The brain is characterized by a complex and integrated network of interacting cells in which cell-to-cell communication is critical for proper development and function. Initially considered as an immune privileged site, the brain is now regarded as an immune specialized system. Accumulating evidence reveals the presence of immune components in the brain, as well as extensive bidirectional commu...

Ageing, defence mechanisms and the immune system.

Of all the systems in the body, the immune system is probably the best understood, both in mechanistic terms and in the ways in which it changes during ageing. Studies of the ageing immune system (immuno gerontology) can be traced back to the early part of this century (and even earlier), and the literature has burgeoned in the last three decades. Perhaps the first publication was of the invest...
