Brief synthesis

Professor Michel Salzet is the director of the unit since 1998 and in 2015 of the Inserm 1192 unit PRISM : Proteomique, Réponse Inflammatoire et Spectrometrie de Masse (http://www.laboratoire-prism.fr) at the University of Lille. Professor Michel Salzet received his PhD in Biochemistry at the University of Lille in 1993, where he has the Chair of Immunology since 1997. After his PhD, Professor Michel Salzet worked as Associate Researcher at the Institute of Neurosciences at Stony Brook University (USA), and was subsequently nominated as Senior Research Scientist at the Beth Israel, Mind Body Institute of Harvard Medical School (1998). He became a member of the Institut Universitaire de France in 1998 until 2003. Professor Salzet is an expert in the field of neuroimmunology and proteomics. Professor Michel Salzet is also co-founder of the Start-Up IMABIOTECH (2009), Clic-Imaging platform (2013) and in 2019, Y-Med Company Professor Michel Salzet currently holds 16 patents.

Research Summary

Over the thirty past years, Professor Michel Salzet research activities are dedicated to neuro and onco-immunology through proteomics approaches. He started on the immune response modulation by endocrine factors such as opioids, cannabinoids, morphine and estrogens, and the characterization of their respective receptors in invertebrates and mammals.

He pursued his work by studying the characterization of novel family of antimicrobial peptides which are issued from neuropeptides precursors in leeches and mammals, as well as the understanding of their involvement in the immune response. Therefore, he performed with his collaborators the characterization of the immune factors and to study their function in the brain regeneration of the leech focusing on sensing receptors (TLR, NLR, RLR), their signaling pathway and the involvement of antimicrobial peptides. Then he identified the enzymes involved in neuropeptide precursors processing in immune cells, especially macrophages.

He evidenced the presence of proprotein convertases family in immune effectors organs. Among the member of this family, he studied the role of the proprotein convertase PC1/3 (PCSK1) in the pro-inflammatory factors secretion from macrophages and investigates its intracellular signaling and trafficking showing that PC1/3 is a key regulator of TLR4 and TLR9 traffickiing. He then showed the implication of PC1/3 in modulation of UNC93B, NOGO B and GRAMD4 chaperones. Then, he investigates this enzyme in clinical problematics, through PC1/3 inhibition in macrophages. The objective is to reverse within the tumor microenvironment the macrophages pro-tumoral phenotype to anti-tumoral one through PC1/3 inactivation. Indeed, PC1/3 KO macrophages have been shown to produce anti-tumor factors under LPS, ODN CpG or Placlitaxel stimulation as well as chemoattractants of T helper lymphocytes switching the immune response to TH1.

In parallel, he developed modern biochemistry approaches namely proteomics for the large-scale identification of proteins, MALDI mass spectrometry imaging to obtain their localization from tissue sections and bridged strategies to get large scale identification from limited area on tissue sections (or spatially-resolved microproteomics). Very interestingly, these developments have led to get interested in the characterization of proteins which were not referenced in the protein databanks.

In collaboration with Professor Xavier Roucou he demonstrated the existence of the so-called “alternative proteins” (or ghost proteins) issued from alternative open-reading frames and non-coding regions of mature RNA. Using in silico approaches, more than 10.000 alternatives RNA have been identified and alternative proteins issued also. The function of these ghost proteins is now beginning to be investigated especially in cancer.

Finally, he participates with Professor Isabelle Fournier in the development of a novel instrument for real time in vivo proteomic with clinic applications for guiding surgery.
