Omega 3 precursors of inflammation resolution molecules.

The resolution of inflammation takes place via the action of resolvins, maresins and protectins, the SPMsSpecialized Pro-resolving Mediators.

Among the natural solutions to reduce inflammation, the long chain omega 3 EPA eicosapentaenoic acid and DHA docosahexaenoic acid are currently very popular. They contribute to a healthy and balanced diet and bring many benefits including cardiovascular health, brain development and morale. But their most sought-after effect is to reduce inflammation. Indeed, they are the precursors of certain mediators studied for twenty years, the molecules of the resolution of inflammation.

The inflammatory response, a natural defense mechanism


When we hurt ourselves or when we face viruses or bacteria, to defend ourselves our body sets up an inflammatory reaction. The first signs appear such as redness, swelling, heat and pain, which will gradually increase over time.

Our body manufactures SPMs: specialized mediators of resolution

In parallel with the pro-inflammatory signals, “stop” signals are put in place: these are specialized mediators of resolution also called SPM (Specialized Pro-resolving Mediators). It is a family of lipids among which we find molecules called resolvins, maresins and protectins and which are obtained from fatty acids from food, omega 3 EPA and DHA.

To date, we know:

type E and D resolvins (RvD1, RvD2, RvD5)

maresines (MaR1)

and protectins (PD1, PDx).

Several steps exist in the metabolism of omega 3 to lead to these molecules of very small sizes. Few scientific teams in the world are able to quantify them using spectrometric methods, our partner Ambiotis is one of them.

The following diagram represents the biochemical cascades resulting in PMS from omega 3s that take place in the human body:

Protective role of PMS

These SPMs are produced to enable the complete shutdown of inflammation by the human body. These molecules are produced during the resolution phase of inflammation and prevent the inflammation from persisting chronically or even silently. Indeed, these resolution mediators will:

promote healing and better recovery after infection or injury,

improve healing and prevent fibrosis so that the tissues regain flexibility and functionality,

avoid letting the inflammation take hold and get worse.


How to promote the production of SPM in our body?


As we have seen, SPMs come from the metabolism of EPA and DHA, so it is important to consume enough of them so that the membranes (storage site for fatty acids) of our cells are rich in omega 3 which will be used to manufacture MPS in the event of an attack.

However, not all omega 3s are created equal! They are not all assimilated in the same way. Thus we compared 18 different food sources of EPA and DHA by studying the amount of SPM produced by immune cells subjected to inflammation. And it is not necessarily the richest sources of omega 3 that produce the most PMS!

Based on these experiments, Aloméa laboratories have developed a resolving complex composed of new generation omega 3s aimed at improving the management of inflammation by the human body, without the use of chemical or medicinal alternatives.
