Type:
Myeloperoxidase (MPO) is a heme-containing peroxidase most commonly associated with neutrophils and certain other myeloid cells. It plays a critical role in the innate immune response by generating reactive oxygen species (ROS) during the respiratory burst, which can destroy pathogens.

MPO is predominantly expressed in neutrophils and monocytes, where it catalyzes the formation of hypochlorous acid (HOCl) and other ROS from hydrogen peroxide and chloride ions.
The generation of ROS by MPO is essential for antimicrobial defense; however, these reactive molecules can also induce oxidative stress in the tumor microenvironment.

MPO is not typically expressed by tumor cells themselves, but high levels can be found in tumor-infiltrating immune cells (e.g., neutrophils) or in areas of chronic inflammation.

Inflammatory Bowel Disease

The main pathways involved in IBD include intestinal barrier dysfunction, mucus barrier impairment, dysbiosis-driven innate immune activation, and persistent cytokine-mediated inflammation. Key barrier components such as ZO-1, occludin, claudins, and MUC2 are commonly disrupted, increasing epithelial permeability and microbial translocation. This promotes activation of inflammatory hubs including TNF-α, NF-κB, IL-1β, IL-6/STAT3, and IL-23/Th17, while JAK/STAT signaling integrates multiple cytokine inputs that sustain chronic mucosal injury. Together, these pathways drive epithelial damage, immune dysregulation, and failure of mucosal healing in ulcerative colitis and Crohn’s disease

Rank Pathway / Axis Representative Targets / Markers Typical Direction in IBD Main Relevance
1 Intestinal Barrier Integrity / Tight Junctions ZO-1 (TJP1), Occludin (OCLN), Claudins (especially CLDN2, CLDN1) ZO-1 ↓, OCLN ↓, barrier loosened; CLDN2 often ↑ Core barrier failure increases intestinal permeability, microbial entry, and chronic inflammation
2 Mucus Barrier / Goblet Cell Axis MUC2, goblet cells, antimicrobial peptides MUC2 and goblet protection often impaired Weak mucus defense exposes the epithelium to luminal bacteria and antigens
3 TNF-α Inflammatory Axis TNF-α, TNFR1, TNFR2 ↑ Major inflammatory driver and validated therapeutic target in IBD
4 NF-κB Signaling NF-κB, IKK, IκB, COX-2, iNOS ↑ Central transcriptional hub for cytokines, chemokines, and inflammatory amplification
5 IL-23 / Th17 Axis IL-23, IL-23R, IL-17A, IL-22, RORγt ↑ / dysregulated Important bridge between innate and adaptive immune inflammation
6 JAK / STAT Signaling JAK1, JAK2, TYK2, STAT3 ↑ / activated Integrates multiple cytokine signals that sustain mucosal inflammation
7 IL-6 / STAT3 Axis IL-6, IL-6R, gp130, STAT3 ↑ Supports inflammatory persistence, immune-cell survival, and epithelial injury signaling
8 IL-1β / Inflammasome Axis IL-1β, NLRP3, ASC, caspase-1 ↑ Promotes innate inflammation, cytokine escalation, and epithelial damage
9 Microbiota / Dysbiosis / PRR Signaling Dysbiosis, TLRs, MyD88, LPS-related signaling Dysregulated / activated Links altered microbiota to barrier loss and immune activation
10 Oxidative Stress / Redox Imbalance ROS, lipid peroxidation, MPO, antioxidant defenses ↑ oxidative stress Contributes to epithelial injury, inflammatory signaling, and impaired healing
11 Leukocyte Trafficking / Adhesion Integrins, MAdCAM-1, ICAM-1, VCAM-1, chemokines ↑ Drives immune-cell recruitment into inflamed intestinal tissue
12 Epithelial Apoptosis / Restitution / Mucosal Healing Caspases, repair pathways, epithelial proliferation and restitution markers Injury ↑, healing impaired Determines whether mucosal damage resolves or progresses to chronic disease
Rank Natural Product Best Fit in IBD Evidence Level Main Rationale Notes
1 Curcumin Mainly Ulcerative Colitis (UC) Best human evidence Strongest overall adjunctive clinical support among common natural products for active UC Anti-inflammatory; NF-κB / cytokines / oxidative stress; mucosal support
2 Indigo naturalis (Qing Dai) Mainly UC Strong efficacy, safety-limited Good human efficacy signals, but safety concerns lower practical rank Anti-colitic; immune/inflammatory modulation; use caution flag for safety
3 Boswellia serrata UC / colitis Older smaller human trials Suggestive remission data and anti-inflammatory relevance, but evidence base is limited 5-LOX / leukotrienes / inflammation / mucosal protection
4 Aloe vera gel Mild-to-moderate UC Small human trial signal Some human improvement signal, though not as strong as curcumin or indigo naturalis Mucosal soothing / anti-inflammatory / healing support
5 Andrographis paniculata / andrographolide Mostly UC Mixed human, stronger preclinical Mechanistically promising, but human benefit is less consistent NF-κB / cytokines / barrier and anti-inflammatory support
6 Carvacrol Experimental colitis / dysbiosis / barrier dysfunction Preclinical Promising anti-colitis terpene with anti-inflammatory, antioxidant, and microbiota-related effects Dysbiosis / intestinal barrier integrity / NF-κB / oxidative stress
7 Thymol Experimental colitis / barrier dysfunction Preclinical Promising anti-colitis terpene with cytokine suppression and NF-κB-related effects Dysbiosis / intestinal barrier integrity / NF-κB / COX-2 / oxidative stress
8 Carvacrol + Thymol Experimental colitis, dysbiosis, bile-acid modulation Preclinical, mechanistically strong Combination may be especially relevant due to microbiota and bile-acid pathway effects in DSS colitis Bifidobacterium / secondary bile acids / barrier support / anti-colitic signaling
9 Peppermint oil Supportive / experimental colitis / GI symptom relief Mainly preclinical for IBD; stronger IBS evidence Menthol-rich oil with anti-inflammatory, antispasmodic, and possible barrier-supportive effects, but limited direct human IBD evidence Menthol / TRP modulation / cytokines / oxidative stress / GI symptom support
