Vitamin C Does Not Boost Immunity—It Refuels the Cells That Kill Pathogens
Vitamin C does not amplify immune function—it restores neutrophil antioxidant capacity between killing events. Approximately 200 mg daily saturates immune…
Brain and Immune System Form Integrated Network, Study Reveals Bidirectional Communication
Neurons and immune cells form an integrated bidirectional network, with neural signals directly regulating immune behavior and immune cytokines reshaping…
How the Brain Controls Inflammation Through the Vagus Nerve
The vagus nerve transmits electrical signals from the brain to the immune system, reducing inflammation through acetylcholine release. Clinical trials…
How the immune system learns to remember threats: the science of innate and adaptive immunity
The immune system operates in two coordinated layers: an immediate innate response acting within minutes, and a slower adaptive response…
How the immune system learns and remembers: innate defenses meet adaptive immunity
The immune system operates as two integrated networks: innate immunity provides immediate broad-spectrum defense within minutes, while adaptive immunity learns…
How Your Immune System Works: A Guide to Its Specialized Cells and Functions
Your immune system is an organized network of specialized cells—dendritic cells, T cells, B cells, and NK cells—each with distinct…
How a single stem cell in bone marrow generates your entire immune system
All blood and immune cells originate from a single pluripotent hematopoietic stem cell in bone marrow. Cytokine signals like IL-3,…
Aging Immune System Fails to Control Gut Microbiome, New Research Shows
New research reveals how the aging immune system fails to control gut microbiome balance, leading to increased inflammation and disease…
