Anna Wójcik-Gładysz’s team studies the neuromodulatory effects of neuropeptides and peripheral hormones involved in appetite regulation on animal growth and reproduction. In recent years, work has focused on the activity of the gastrointestinal hormones ghrelin and obestatin and their participation in the regulation of gene and protein expression of key hormones of the gonadotrophic and somatotrophic axis in the hypothalamic-pituitary system. Another objective of the team is the action of BDNF in depressive disorders associated with obesity, which simultaneously generate irregularities in the functioning of the gonadotrophic axis. Research is conducted on sheep, which is not a typical model for application research; however, the obtained results provide valuable and unique information that forms the basis for further research, leading to a better understanding of the processes underlying such disorders as anorexia and bulimia.
Research interest:
Neuroendocrinology, hormone regulation, animal physiology.

Anna Antuszewicz (Antushevich H.) graduated with honors from the Grodno State Agrarian University in Belarus (BSc) and the Warsaw University of Life Sciences SGGW, Faculty of Animal Science in Poland (MSc, PhD). She obtained her DSc (habilitation) in 2017). Currently, she is a professor at the the Department of Genetic Engineering at the Kielanowski Institute of Animal Physiology and Nutrition, Polish Academy of Sciences (Jabłonna, Poland). Her research interests concentrate on: 1) the role of adipose tissue and regulatory peptides in gastrointestinal tract functioning (intestinal epithelium maturation, digestive enzymes secretion, inflammation); 2) the role of adipose tissue in bacterial adhesion to enterocytes (in vitro experiments); 3) the role of fecal microbiota transplantation in gastrointestinal disease therapy. Also, she is involved in studies concerning the effect of endotoxin-induced inflammation on the hypothalamic-pituitary-gonadal axis in ewes.
Research interests:
Gastrointestinal tract physiology, inflammatory bowel diseases, regulatory peptides, bacterial adhesion, obesity, fecal microbiota transplantation.

Małgorzata Białek holds a PhD in agricultural sciences, having graduated from the Faculty of Human Nutrition and Consumption Sciences of the Warsaw University of Life Sciences. Since 2016 she has been working at the Kielanowski Institute of Animal Physiology and Nutrition, Polish Academy of Sciences, firstly as a research assistant and then as an assistant professor. Her scientific interests are focused on conjugated fatty acids (CLA and CLnA isomers): methods of analysis, metabolism and mechanisms of actions, under both physiological and pathological conditions. She has also been working on assessing the effects of dietary supplementation of both laboratory and farm animals with bioactive compounds (fish oil, pomegranate seed oil, carnosic acid, seleno-compounds, lycopene) on the lipids profile, enzyme activity, antioxidant status and content of the elements in selected tissues.
Lipidomics, conjugated fatty acids – metabolism and mechanisms of actions under physiological and pathological conditions, peroxidation, chromatography, chemometrics.
