ANIMAL BIOLOGY LABORATORY

Research directions

  • • Modulation of the humoral and cell immune response under the action of various dietary factors (e.g. bioactive compounds: polyphenols, unsaturated fatty acids, fibre); alternative feed sources (agrifood residues/by-products, natural additives, etc.);
  • • Evaluation of the effects of feed contaminants (e.g. mycotoxins) on animal and human health, support for the development of national and European regulations on the maximal level of mycotoxin tolerance in feeds for farm animals.
  • • Evaluation of the effect of various dietary compounds (e.g. polyphenols) or contaminants (e.g. fungal/non-fungal) on the gastrointestinal tract, as first absorption barrier and immune defence; in vitro studies (culture of epithelial, blood, renal, hepatic cells, etc.), in vivo (pig, poultry, etc.) and ex vivo (intestine, mesenteric lymph nodes and Payer plates) resulted from trials on farm animals; nutrigenomics and proteomics studies;
  • • Adaptation and development of methods of enzymatic biochemistry; activity evaluation for enzymes with primordial role in metabolism and oxidative stress
  • • Adaptation and development of methods/techniques to dose contaminants (mycotoxins).

 

COMPARTMENTS OF THE LABORATORY OF ANIMAL BIOLOGY:

 

COMPARTMENT FOR CELL CULTURES:

Performing in vitro experiments using:
- primary cells (lymphocytes, monocytes, neutrophils), blood cells and cells from immune organs (spleen, lymph nodes)
- lines of intestinal, renal and hepatic cells: pig (IPEC-1, LLCPK) and human (CaCO2, Hepa)

 

 

COMPARTMENT OF MOLECULAR BIOLOGY:

analysing the gene expression of different biomarkers playing an important role in the metabolic and physiologic processes taking place in cells and tissues (blood, organs, muscles, milk); PCR/qPCR/qPCR array applications to determine the gene expression for: cytokines/enzymes/signalling molecules/proteins/receptors, etc.;

 

 

COMPARTMENT OF BIOCHEMISTRY (PROTEOMICS):

Investigating, by biochemical techniques, electrophoresis, western blot and ELISA, the profile and concentration of different proteins/glycoproteins/phosphoproteins from blood, cells and tissues: e.g. immunoglobulins/cytokines/signalling molecules/proteins/milk/other proteins

 

 

COMPARTMENT OF PHYTOCHEMISTRY:

Investigating bioactive compounds (e.g. polyphenols) from natural extracts and feeds, by determining their antioxidant activity, concentration, UV-Vis spectrum and inhibition of pro-oxidant enzymes (lipoxygenase, etc.).

 

 

The Laboratory of Animal Biology evaluates the sanitary-veterinary quality of raw materials used in animal feeding by: Mycotoxicological analyses – fast mycotoxins screening
