OVERVIEW

he lessons contained in the course of General Pathology and Immunology are intended to provide a biotechnology student with a general picture of the defense methods implemented by our immune system against etiologic agents and neoplasms. The course also analyzes the pathogenetic mechanisms of inflammatory response and neoplastic transformation.

AIMS AND CONTENT

LEARNING OUTCOMES

In-depth knowledge about the main molecular and cellular mechanisms of the immune response (natural and adaptative) against pathogens and tumors. Knowledge about hypersensitivity reactions and related conditions.

AIMS AND LEARNING OUTCOMES

The part of General Pathology gives in-depth knowledge on the inflammatory process The concepts of angioflogosis and histoflogosis will be defined and characterized. Important aspects of general oncology will be addressed, such as the definitions of oncogene, tumor marker and metastasis. The classification of tumors on the basis of behavior, histogenesis, grading and staging will be defined.

About Immunology, the physiology of the immune system and the peculiar feature of innate and adaptive immune response will be deeply characterized. Finally, some of the principal pathological aspects of immune system will be described.

TEACHING METHODS

These topics are explained by the teacher through PowerPoint presentations and the lessons are shared on Aula Web. However, the teachers always recommend the use of a textbook to expand the overall view of the subjects

EXAMS

EXAM DESCRIPTION

The exam takes place orally in the presence of the teachers of the disciplines concerned.

The student answering to the questions formulated by the teachers must demonstrate to be able to critically discuss all the topics covered by the application.

ASSESSMENT METHODS

Verification of learning through the oral examination allows students to verify the actual acquisition of the expected learning outcomes.

To pass the exam, the student must demonstrate:

- to know the etiological bases and the pathogenetic mechanisms of human diseases and to know how to analyze the main cellular and molecular aspects;

- understand the different immunological mechanisms involved in the immune response and some of the pathologies responsible for defects in the functioning of the immune system (Hypersensitivity reactions).
