Mold & Your Brain Mold & Your Brain: How Mycotoxins Impact Cognitive Health Some molds produce toxins called mycotoxins . While they don’t “invade” the brain, they can affect the blood–brain barrier —the protective layer surrounding your brain. Why It Matters A compromised barrier allows immune signals to trigger inflammation in the brain, which may lead to: Brain fog Anxiety Sensory sensitivity (light, sound) Fatigue that feels “neurological” How It Happens Mycotoxins make t

Mycotoxins & Cellular Efflux Mycotoxins and Cellular Efflux Pump Suppression One of the least discussed yet highly consequential effects of chronic mold exposure is its impact on cellular efflux transporters , particularly ATP-dependent pumps such as P-glycoprotein (P-gp)  and other ABC transporters. These transporters are located in cell membranes throughout the body, including the gut lining, liver, blood–brain barrier, kidneys, and immune cells. Their role is not classical
