About

Gijs Kooij is a PI (assistant professor) at the Department of Molecular Cell Biology & Immunology as well as the MS center Amsterdam. His main research focus is to understand the natural process to resolve neuro-inflammation in order to provide new perspectives on the pathogenesis of chronic (unresolved) neuro-inflammatory diseases like multiple sclerosis (MS) and to reveal new treatment opportunities. He recently discovered endogenous lipid mediator circuits in the central nervous system (CNS) and revealed the absence of protective lipid mediators in various disease stages of MS. These findings in combination with personal Vidi (NWO) and Fellowship (Dutch MS society) grants have enabled him to establish his own research group on inflammation-resolution mechanisms in health and disease.

(Re)solving MS: Understand and exploit endogenous protection mechanisms.

Inflammation is a host-protective response when properly orchestrated. Beside immune checkpoints, the inflammatory cascade boasts an additional checkpoint, driven by chemical lipid mediators that induce resolution of inflammation. These novel autacoids, called specialized pro-resolving lipid mediators (SPMs), not only inhibit the inflammatory response, they also actively terminate it, leading to the restoration of tissue homeostasis. Novel sensitive detection methods (i.e. lipidomics) have set the stage to identify and decode these SPMs, which opens new perspectives on the pathogenesis of chronic (unresolved) inflammatory diseases like multiple sclerosis (MS).

By using a state-of-the-art lipidomics and mass-spectrometry imaging approach in combination with primary cell cultures, ex vivo brain slice cultures, in vivo neuro-inflammation models and human post-mortem tissues, we will elucidate in the coming years how altered inflammation-resolving mechanisms underlie MS pathogenesis by investigating both fundamental (Vidi) and clinical (fellowship) aspects. His ultimate goal is to provide novel diagnostic, prognostic and therapeutic opportunities for MS and other chronic (neuro-)inflammatory diseases based on resolution pharmacology (Figure 1).

Figure. Decision paths during neuro-inflammation: chronicity or resolution?
An effectively mounted inflammatory response will also trigger the activation of protective resolution pathways intended to safely terminate the inflammatory cascade and promote healing (1). Failed resolution can extend in time the actions of pro-inflammatory mechanisms resulting in prolonged (chronic) inflammation (2). I here propose that activation of endogenous circuits of resolution through novel resolution-based therapeutics (SPMs) can restore tissue structure and function to return to homeostasis (3).
