Altered Ca<sup>2+</sup> Homeostasis in Immune Cells during Aging: Role of Ion Channels
Aging is an unstoppable process and begins shortly after birth.

| Summary: | Aging is an unstoppable process and begins shortly after birth. Each cell of the organism is affected by the irreversible process, not only with equal density but also at varying ages and with different speed. Therefore, aging can also be understood as an adaptation to a continually changing cellular environment. One of these very prominent changes in age affects Ca<sup>2+</sup> signaling. Especially immune cells highly rely on Ca<sup>2+</sup>-dependent processes and a strictly regulated Ca<sup>2+</sup> homeostasis. The intricate patterns of impaired immune cell function may represent a deficit or compensatory mechanisms. Besides, altered immune function through Ca<sup>2+</sup> signaling can profoundly affect the development of age-related disease. This review attempts to summarize changes in Ca<sup>2+</sup> signaling due to channels and receptors in T cells and beyond in the context of aging. |
