Research activities

Research projects are buttressed by those of INSERM unit U935 (formerly EA3805), which was recently labeled (on its site in Poitiers) with the title “Malignant and therapeutic stem cells”. In basic and translational research , the unit is specialized in the study of malignant stem cells in two pathologies: chronic myeloid leukemia (CML) and glioblastoma.


The team studies the mechanisms of genetic instability in the leukemic stem cells at the origin of resistances in mouse and human stem cell models. It also explores the mechanisms of anti-CML anti-leukemia immunity.  In collaboration with CIC INSERM 802, it is developing new tests for detection and quantification of leukemic stem cells in patients treated with tyrosine kinase inhibitors. With regard to glioblastomas, techniques for isolation and quantification of tumor-initiating cells are being developed, as are techniques for targeting these cells with new drugs (collaboration with the neurosurgery, medical oncology, radiotherapy and pathological anatomy departments…).

As concerns the modeling of future cell therapies, the unit is developing experimental models using cell programming techniques, particularly in transversal programs (collaboration with INSERM U1082, Inra, CIC 802) and in collaboration with the pluripotent stem cell platform of Université Paris Sud 11.

The projects are supported by: phRC, STIC, Ligue, Fondation contre la leucémie, ARC, CGO, région Poitou Charentes, association Sport et Collection.

Inflammation, allergy and cytokine laboratory 

Diagnosis and follow-up

  • specialized examinations at the Biochemistry / Immunology interface:
  • electrophoresis (serum, urine, CRL, Hb)
  • quantitative assay of inflammatory proteins, immunoglobulins, complement, cytokines and protein deposits
  • functional exploration of the complement
  • allergy exploration  (specific IgE antibodies and mediators)

Research activities

Research activity in direct connection with the Litec (university laboratory specialized in inflammation, epithelial tissues and cytokines) EA 4331: Project centered on the study of: 1) the mechanisms inducing tissue inflammation (cytokines, bacteria); 2) the interaction of inflammatory cells with attacked tissues; 3) tissue repair; 4) regulation of these different mechanisms by cytokines.
Immunology laboratory 

Diagnosis and follow-up

Activities pertain mainly to the diagnosis of autoimmune diseases, lymphoproliferative disorders (myeloma, Waldenstrom’s disease, chronic lymphocitic leukemia) or infectious processes:

  • Screening of monoclonal immunoglobulins that is essential to the diagnosis and monitoring of  lymphoproliferative syndromes. Immunoelectrophoresis, immunofixation and immunoblot of serum and urines. This activity is associated with that of the reference center for rare diseases and deposition diseases  (amylosis, Randall’s disease, etc).
  • Detection and determination of antibody specificities in a number of autoimmune diseases by indirect immunofluorescence, ELISA, immunodot.
  • Assessment of in vitro anti-mycobacterial T-response by tests studying the production of IFN-g in response to stimulation by the highly specific antigens of Mycobacterium tuberculosis; tuberculosis diagnosis tests. These tests shall be replacing the tuberculin skin test.

Research activities

The laboratory’s research activities are buttressed by those of Inserm UMR 935: “Leukemic and therapeutic stem cells”. The research themes revolve around the pathogenesis of chronic myeloid leukemia (CML), the study of normal stem cells and control of the disease by the immune system.

Clinical pharmacology and hemovigilance 

Diagnosis and follow-up

Transfusion safety, hemovigilance and biovigilance
In association with the EFS (the French blood establishment), the hemovigilance cell ensures transfusion safety (coverage of needs, safety of blood products from donor to recipient, traceability). As for hemovigilance (set up in 1996), it is a monitoring system that records and analyzes any incidents occurring during or following a transfusion, and institutes corrective measures.  The incidents are centralized by the AFSSAPS (French agency for sanitary safety of health products).
Biovigilance is a surveillance system for organ and tissue grafts; incidents are centralized by the agency of biomedicine and the AFSSAPS.

The hemovigilance unit formalizes the actions undertaken by the CSTH (transfusion and hemovigilance safety committee); it works in close association with the “health care quality and safety” commission.

Research activities

The hemovigilance cell conducts epidemiological studies focused in the qualitative aspects of transfusion procedures and indications for transfusion.

Virology and mycobacteriology laboratory 


Diagnosis and follow-up

The virology medical unit (MU) includes 3 activity sectors; cellular virology, molecular virology and immunoserology; taken together, they ensure diagnosis, therapeutic monitoring and epidemiological surveillance of viral diseases.


Molecular virology, which enables detection and quantification of viral genomes as well as genotyping and characterization of the mutations resisting antiviral treatments, has undergone pronounced development over recent years, and now constitutes one of the laboratory’s major activities.

The department is certified for antenatal diagnosis and detection of the influenza viruses necessitating level 3 biological safety, and it coordinates diagnosis of influenza and respiratory infections for the Poitou-Charentes region in the “flu infection observation group”(GROG).

The department constitutes a reference center in virology. It benefits from strong regional attractiveness, with close to 30% of requests coming from outside.

Research activities

The group is focused on the human papillomavirus (HPV) infection implicated in some cancers (cervical, anal, oropharyngeal).


Diagnosis and follow-up

The mycobaceteriology medical unit provides diagnosis, therapeutic monitoring and epidemiological surveillance of mycobacterial infections (+ anti-tuberculosis drug resistance), chlamydia infection, mycoplasms and rickettsial infection.

In accordance with legislation, the department is equipped with a level 3 biological safety laboratory and constitutes a mycobacteriology reference center on a regional level.
