Generation of monocytes-derived dendritic cells from chicken blood for in vitro studies
Commonly used acronym: DENDRICHICK
Scope of the method
- Animal health
- Regulatory use - Routine production
- Translational - Applied Research
- In vitro - Ex vivo
- Animal derived cells / tissues / organs
- dendritic cells
- Dendritic cells isolation
The purpose of the present development is to use avian MoDCs to implement a cellular platform to increase understanding of the immune responses induced by various antigens of interest (e.g. vaccine candidates) and evaluate their immunogenic potential. Considering the difficulty to work on dendritic cells (DCs) isolated ex vivo, we developed a protocol for using in vitro-generated chicken monocyte-derived dendritic cells (MoDCs). Plastic-adherent peripheral blood mononuclear cells (PBMCs) isolated from specific-pathogen free (SPF) chickens are cultured with GM-CSF and IL-4 for 5 days at 41°C in 5% CO2 atmosphere. Following antigen-induced maturation (e.g. LPS, polyinosinic-polycytidylic acid, viral antigens, etc.), typical DC morphology is confirmed by microscope. The endocytic capacity and the expression of surface expression of mannose receptor C-type 1-like B, MHC-II, myeloid markers CD11c, DEC205, and co-stimulatory molecules CD40, CD80, CD86 by MoDCs at different maturation states are assessed by flow cytometry.
- Biosafety cabinet,
- Cell incubator,
- Flow cytometer.
- Still in development
Pros, cons & Future potential
- - Poorly invasive (MoDCs used in place of bone marrow-derived DCs);
- - Makes it possible to assess the response to an antigen in a large number of individuals and thus evaluate individual variability.
Antibodies for cell characterization are not all commercially available.
- - Selection of immunopotentiating agents (e.g. adjuvants) during vaccine development;
- - Antigen-pulsed MoDCs will be co-cultured with naïve purified T cells to characterize cell-mediated responses triggered by vaccine candidates in vitro.
