Iodine and Immunity: How Balance Affects Your Immune System

According to a narrative review published in the journal Nutrients by researchers at the University of Guelph and ImmunoCeutica Inc., iodine intake follows a narrow U-shaped relationship that dictates how the micronutrient influences immune defenses across humans and domesticated mammals. While adequate intake supports leukocyte metabolism and thyroid-driven immunity, both chronic deficiency and sustained excess … Read more

New Immune Receptor Identified as Key Driver of Organ Aging

Stanford Medicine researchers have identified a primary driver of biological aging: the failure of tissue-resident macrophages to clear senescent, or “zombie,” neutrophils from the body. According to a study published July 16 in Science, blocking a specific pro-inflammatory receptor, EP2, on these immune cells rejuvenated organ function and reduced age-related frailty in mice. This discovery … Read more

Why Autoimmunity Increases With Age: The Role of Senescent Immune Cells

Immune aging, or immunosenescence, triggers a decline in the body’s ability to fight infections and tumors while simultaneously increasing the risk of chronic inflammation and autoimmune diseases. According to a review published in the Journal of Clinical Investigation, the human immune system reaches a critical inflection point around age 50, where molecular signatures of aging … Read more
