“To compensate for this immunological deficit, breast milk contains a multitude of components that work together in a synergistic fashion to supply a compensatory immune "system." This system confers both active and passive immunity to protect the growing infant.”

“One source of TLR4-mediated innate immune activation is thought to be chronic exposure to lipopolysaccharide by certain conditions, such as intestinal permeability. In many ways, the immune system's response to lipopolysaccharide via TLR4 is a canonical example of innate immune activation in response to common pathogens.”

“At rest, one signaling molecule (IL-2) was slightly lower, and there was no broad increase in inflammatory cytokines. The immune system wasn't more inflamed at baseline after urolithin A supplementation, but it was more primed to respond.”

“Interestingly, acute activation of the immune system can temporarily reduce inflammation and its accompanying depressive symptoms. In this clip, Dr. Charles Raison describes the complex relationship between inflammation and depression.”

“T helper, type 2 (Th2) cells coordinate with eosinophils, mast cells, and other immune cells to attack extracellular pathogens such as parasites. However, when the immune system reacts abnormally, these immune cells play a central role in the development of allergies to foods, pets, pollen, and other environmental triggers.”

“Vitamin D also increases T-regulatory cells, which play a major role in keeping the immune system in check, particularly when it comes to autoimmune diseases. Vitamin D inhibits the production of proinflammatory cytokines, which can play a role in a cytokine storm.”

“Interferons are responsible for the hallmark symptoms of an infection: fever, muscle pain, and "flu-like" symptoms. SARS-CoV-2 – the virus that causes COVID-19 – attempts to evade the immune system by suppressing the interferon response.”

“In early-stage cancer, the initial suppression of autophagy may help prevent attracting undue attention from the immune system but may facilitate ongoing transformation. In later-stage cancer, autophagy may help cancer cells survive within the hostile tumor microenvironment.”

“An infant's immune system is the last of the biological systems to develop, taking months or even years to match an adult's capacity for defense.”

“Vitamin C also appears to boost the immune system by promoting the proliferation of T cells and preventing T cell death. T cells play a major role in driving an immune response against pathogens such as bacteria or viruses.”
