BRS3(PM1) - NF-kB Signalling Regulation
1. Definition
Regulation of the NF-kB inflammatory transcription pathway that drives pro-inflammatory gene expression.
Within BRS3, this PM captures one of the core inflammatory-control nodes through which diet can influence transcriptional inflammatory tone rather than simply downstream symptoms or biomarker expression [1][2].
2. Intervention Breakdown
Food-State Dominant
3. Functional Role
↓ inflammatory transcriptional activation
4. Mechanistic Basis
Summary
BRS3(PM1) links polyphenol-rich, omega-3-supported, and gut-supportive food patterns to lower NF-kB-driven inflammatory signalling within BRS3(FM1) - Anti-Inflammatory Signalling Tone [1][2].
NF-kB signalling and inflammatory transcription
(NF-kB as an inflammatory control node)
NF-kB regulates expression of multiple pro-inflammatory genes and sits upstream of broader cytokine and immune-signalling responses relevant to BRS3 inflammatory tone.
(Dietary modulation context)
Polyphenol-rich foods, omega-3 intake, and lower-endotoxemia meal patterns may help reduce signalling pressure on this pathway, especially when repeated as part of a stable dietary pattern rather than used as isolated bolus inputs [1][2].
(Cross-system context)
Because endotoxin exposure and barrier integrity shape inflammatory signalling burden, this PM also depends partly on gut-linked context imported through cross-BRS dependencies listed in §5.3.
5. Underlying Mechanisms and Requirements
5.1 Co-factors
- polyphenols
- omega-3
- magnesium
5.2 KCs (Key Constraints)
5.3 Cross-BRS Links
- BRS5(PM3) - Gut Barrier / Tight Junction Integrity
6. Dietary Levers
Diet
- NF-kB-modulating polyphenols ← berries, green tea, extra virgin olive oil
- EPA/DHA ← oily fish
- Fibre-rich whole-food patterns ← legumes, oats, vegetables
7. Lifestyle Levers
Lifestyle
- Reducing ultra-processed food exposure may help lower postprandial inflammatory burden where this PM is relevant.
- Regular meal timing and stable daily dietary patterning matter more than isolated anti-inflammatory meals.
8. Scoreable Inputs & Modulation Signals
This PM is scoreable through food-state and nutrient signals relevant to inflammatory signalling tone.
Scoreable Input Categories
| Input Category | Example Inputs | PM1 Relevance |
