Course objectives

The objective of the Human Biology course is to develop:

1. The understanding that living systems, including humans, have hierarchically ordered levels of organization with their own specificity and rules that determine biological features and functions.

2. The notion that humans, as a product of biological evolution, are ecologically connected to the development of nature and of the biosphere as a whole.

3. The ability to apply biological rules as scientific theory and methodology of medicine.

4. Practical skills and knowledge of basic biological techniques with medical application.

Course tasks

  • Proficiency in the most important properties and manifestations of the organismal world and humans in particular:
  • molecular and cellular basis of life;

    The present research topics in the Department of Medical Biology are connected with:

    • Investigation of the cellular mechanisms of proliferation and apoptosis.

    • Expression of different antigens (blood group, lysosomals and galectins) in tumor cell lines and in human tumors.

    • Effects of natural and synthetic substances on the induction of immune response and cytokine secretion in vitro.

    • Effects of biological and synthetic preparations on cell cultures in vitro.

    • New disease biomarkers in tumorogenesis.

    • Expression profiles i human diseases personalized molecular medicine.

    There are three research laboratories in the Department of Medical Biology equipped for experimental and diagnostic work in the field of cell and molecular biology and fundamental and clinical immunology.
