MMP-9 is an important marker for those suffering with CIRS from Biotoxin/Mold exposure. However, it is also a great for identifying inflammation associated with some of the most common chronic illnesses out there, including Autoimmune Diseases, Heart Disease, Cancer, and even chronic stress. But certain genes can make you more susceptible.
MMP9: Why is it important?
MMP-9 is one of a class of zinc-dependent enzymes called Matrix metalloproteinases (MMPs), which are involved in the body’s natural process of tissue repair and replacement. MMP-9‘s protein breakdown properties help stimulate the immune response that initiates development and may exacerbate disease progression (R).
Physiologically, MMP-9 plays a role in normal tissue growth and repair processes such as neurite growth, embryonic development, blood vessel creation, ovulation, wound healing, and bone formation (R).
MMP9 Destroys the Blood Brain Barrier (BBB)
Inhibitors of MMPs have been shown to restore Blood Brain Barrier (BBB) integrity (R).
Conditions & Situations With Increased MMP9
- Cancer (in blood) (R) – including Breast Cancer (R)
- Inflammatory diseases, including CIRS (mold exposure) (R)
- IBD (Crohn’s, Colitis) (R)
- Emotional Stress (R)
- Obesity – Higher MMP-9 levels are found in obese subjects (R, R2) and MMP-9 is correlated with BMI (R).
- Neuropathic pain – MMP9 is critical for neuropathic pain (R)
- Heart disease (atherosclerosis, etc…) (R). In heart attack models, MMP-9-deficient mice showed reduced rupture rate (R).
- High blood pressure (R)
- Arthritis (R) – in affected tissue (R). The activation of MMP-9 production in tissue decreases collagen synthesis rates (R).
- Diabetes (R)
- Multiple sclerosis – lesions are correlated with MMP9 levels (R). In individuals experiencing an exacerbation of MS, MMP9 was found to be elevated in the spine (R). Furthermore, treatment with an MMP inhibitor halted the progression of MS in animal models (R).
- Alzheimer’s (R)
- Lupus (in blood) (R)
- Sjogren’s (in tear producing glands) (R)
- Systemic sclerosis (in blood) (R)

- Growth & Development (R)
- Wound healing (R)

Activators of MMP9
MMP-9 is secreted by a wide number of cell types, including neutrophils, macrophages, and connective tissue cells (R). Macrophages (the scavenger type of white blood cells) are a potent source of MMP-9 (R).
- Psychological, emotional stress and activation of the nervous system (R) – causes neutrophils to release MMP9.
- Fungal toxins (T-2 toxin) (R)
- Amyloid beta (R, R2)
- TGF beta1 (R)
- VEGF (R) – MMP-9 also increases VEGF (R).
- NGF (potentiates) (R). MMP9 also potentiates nerve growth factor neurite growth (R)
- Angiotensin II (via Nf-kB, EGF and MAPK) (R)
- Aldosterone (via NF-κB) (R)
- Osteopontin (R)
- Nf-kB (R)
- Reactive oxygen species (ROS) (via NF-κB) (R)
- IL-1b (R)
- TNF (R) – especially potent
- Other MMPs, including MMP-2, -3, -13, -17, and -26 (R, R2, R3, R4)
- Plasmin (R)
- Urokinase-type plasminogen activator (uPA) (R)
- Tissue-type plasminogen activator (R)
- Heat shock protein 60 (HSP60) (in white blood cells) (R)
- Epidermal growth factor (EGF), basic FGF (connective tissue growth factor), PDGF (Platelet derived growth) (R)
- All protein degrading enzymes released from neutrophils promote MMP-9 activation (R)
