The main aim of this course is to introduce students to the normal and pathological function of the immune system. The focus is on the explanation of physiological processes that enable normal functioning of certain subtypes of immune cells in a nonspecific and specific immune response, as well as on the explanation of pathophysiological mechanisms leading to disorders of normal immune processes, as well as on the possibilities for therapeutic action to the immune response. Teaching tasks imply enabling the student to connect basic knowledge of immunology and pathophysiology of the immune system with the teaching of physiology and pathophysiology, microbiology and parasitology, pathology, infectious disease, oncology and epidemiology (vaccination), therefore, qualifying the student to apply immunological cognition in clinical medicine.
