Bird Models

These models are used to identify the neuroendocrine and neurochemical mechanisms involved in the activation and the sexual differentiation of the brain and reproductive behaviors:

  • Quail and song bird models of endocrine control of sex differences and of the sexual differentation of brain and behavior
  • Quail models of control of reproductive behaviors by steroids and catecholamines
  • Bird models of role of steroids on brain morphology and behavior
  • Song bird models of control by steroid and the impact of social environment on brain plasticity

Transgenic mouse models

To study the sexual differentiation of brain and analyze the neural circuits underlying reproduction, including behavior, researchers at GIGA use different transgenic mouse models such as:

  • Aromatase knock-out (ArKO) mouse model to study the role of oestradiol in the development of female brain
  • Kiss-KO mice: targeted mutation in the Kiss1 gene to study the role of kisspeptin in reproductive physiology and behavior
  • nNOS-KO mice: targeted mutation in the gene encoding the neuronal form of the nitric oxide synthase enzyme, which is important for the production of the gazeous neurotransmitter nitric oxide (NO). This model is also used to study the role of NO in reproductive physiology and behavior
  • Kiss-Cre mice and GnRH-Cre mice: to specifically delete (by viral ablation for example) or stimulate by optogenetics kisspeptin or GnRH neurons and then determine their effects on reproductive physiology and behavior

Neuroanatomical and histochemical studies

Neuroanatomical and histochemical studies are performed on brain tissues, postmortem analyses of patient with disorders of sexual differentiation (DSD) or suffering from gender dysphoria (GD).

Neuroendocrine and neurochemical mechanisms

We have investigated the neuroendocrine and neurochemical mechanisms involved in the activation and the sexual differentiation of the brain, reproductive behaviors and the onset of puberty. More specifically, we have analyzed the impact of endocrine disruptor chemicals (EDC) on puberty onset and hippocampal neurogenesis.

Preclinical imaging

Our GIGA platforms offer advanced preclinical functional and anatomical imaging solutions for a broad spectrum of application fields.

Our range of techniques includes:

Magnetic resonance imaging (MRI) scanners use strong magnetic fields and radio-waves to visualize detailed internal structures. Images are obtained in vivo with very high spatial and temporal resolution, good contrast for brain and soft tissues. MRI can be used in a wide variety of applications including anatomical, functional (fMRI) and molecular imaging for medical diagnosis, staging of disease and for follow-up without exposure to ionizing radiation.

Our system, Agilent MicroMRI 9,4T 310 ASR, is equipped with a technical imaging unit (MINERVE). It ensures the admission and extraction of anesthetic gas, thermoregulation of the study subject and monitoring of vital signs such as respiratory and cardiac frequencies.

Computed Tomography (CT) is a non-destructive technique that yields structural and anatomical high-resolution 3D images with limited or no sample preparation required. This imaging modality complements the metabolic or functional images obtained with PET.

Being equipped with two beds for mice (25 mm) and rats (75 mm), our system, the TriFoil Imaging eXplore CT 120 micro-CT, is designed to visualize, quantify and characterize anatomical parameters in small animals. The system is also equipped with a technical imaging unit (MINERVE), ensuring the admission and extraction of anesthetic gas, thermoregulation of the study subject and monitoring of vital signs such as respiratory and cardiac frequencies.

Positron Emission Tomography (PET) has the sensitivity at picomolar level to visualize molecular processes in 3D. In vivo PET imaging with labelled lead compounds will help to select the best one for clinical trials.

 

The technique allows:

  • The collection of quantitative and dynamic biodistribution data (e.g. micro-dosing studies) at an early stage of the clinical development: dynamic data for in-depth kinetic modeling, online blood measurements and in-brain positron-emission measurements
  • Detailed drug occupancy studies (proof of targets, mechanism, efficacy, pharmacokinetics, biodistribution)
  • Concentration analysis of targeted analytes after having developed and validated a dedicated method using microdialysis, a technique used for continuous measurement of free, bound analyte concentrations in the extracellular fluid. Analytes may include endogenous molecules (e.g. neurotransmitter, hormones, glucose, etc.) to assess their biochemical functions in the body, or exogenous compounds (e.g. pharmaceuticals) to determine their distribution within the body)

We are authorized to conduct research programs with classical (18F-FDG) and original radiotracers. Furthermore, we have developed expertise in experimental design, data collection, correction and modeling for kinetic analysis.

Being equipped with two beds for mice (25 mm) and rats (75 mm), our system, the Siemens Concorde FOCUS 120 micro-PET, is designed to visualize, quantify and characterize anatomical parameters in small animals. The system is also equipped with a technical imaging unit (MINERVE), ensuring the admission and extraction of anesthetic gas, thermoregulation of the study subject and monitoring of vital signs such as respiratory and cardiac frequencies.

Our equipment includes the high-resolution, high-frequency ultrasound imaging system Vevo 2100 (Visualsonics). This is a non-invasive, in vivo micro imaging system, enabling visualization, assessment and measurement of anatomical structures and hemodynamic function in longitudinal studies for small animal phenotyping.

The Xenogen IVIS 200 system is a highly sensitive and flexible system to trace bioluminescent reporter genes both in vivo and in vitro. It allows non-invasive longitudinal monitoring of disease progression, cell trafficking and gene expression patterns in living animals. By performing spectral fluorescence imaging, it allows the simultaneous use of bioluminescence and fluorescence imaging.

Bioluminescence imaging uses the enzyme, luciferase, that can be inserted into the genome of cancer cells or the cells you wish to track. Once these cells are implanted within mice, a tail vein or intra-peritoneal injection of luciferin (luciferase substrate) allows to follow their distribution ex vivo without euthanasia.

Intravital microscopy is an extremely powerful tool that enables imaging several biological processes in living animals. In particular, to analyze:

 

 

  • Recruitment processes of leukocytes and platelets on microvessel endothelia
  • Bacterial adhesion on the microvessel endothelia
  • Thrombi and vascular occlusion formation
  • Lymphocytes migration to lymph nodes and lymphocytes adhesion to endothelia

Our equipment includes a motorized Olympus Cell R (Upright) microscope with EMCCD camera, controlled via the Slidebook software.
