Advice
• for successful learning• and passing the exam
Immunology
Lectures (15)
Labs (10)
Seminars (20)
• independent subject (separated from Microbiology)• winter semester• 45 hours during 15 week
Seminars, Labs and Lectures are integral parts of the course
Student are allowed to be absent on seminar or lab twiceduring the semester
Textbook
Basic Immunology: Functions and Disorders of the Immune System- Authors: Abbas AK, Lichtman AH.- Publisher: Elsevier- 3rd edition updated, 2011
.ppt presentations and authorised supplementary material (available on web site)
Activity during the course (seminars, labs and lectures) through activity points
Continuous assessment
Colloquium – divided in three separate mini-tests after every 4 weeks (5th, 9th and 13th week)
Presence on lectures noted separately
Final test
Test (multiple choice – 1 correct answer out of 4)
- first: in the 5th week (first 4 chapters from the textbook)
- second: in the 9th week (chapters 5 to 8)
-third: in the 13th week (chapters 9 to 12 plus immunological methods and vaccines)
Colloquium
15 minutes per mini test
It consists of 30 questions in total (divided into 3 mini tests with 10 questions each)
1 point for each correct answer (max 30 points)
Threshold for passing the final test is 36 points (50% plus 1)
Final test
70 points in total
consists of:
• 20 multiple choice questions with one correct answer out of four (2 points for each correct answer, max. 40 points)
• 5 fill-in questions where correct word should be filled in the blanks (max. 20 points)
• 2 questions that require short answers up to five sentences (max. 10 points)
Final mark in Immunology
For the passing of the Immunology exam the minimum of 51 points (out of 100) should be collected on condition that the 50% of points plus one (minimally 36) has been reached in the final test
Note: If the student collected less than 15 points in colloqium (i.e. 50%), he/she must perform better than 36 in the final test
100 points in total
51-60 6 (six)61-70 7 (seven)71-80 8 (eight)81-90 9 (nine)91-100 10 (ten)
Activity points (max. 10 points) are added only if the minimum of 51 points has been reached

Principle mechanisms of innate and adaptive immunity
Mechanisms of adaptive immunity
- acquired throughout a lifetime of an individual
- result of previous contact with pathogen
- present in vertebrates
Properties of adaptive immunity
- diversity and specificity
- memory
- clonal expansion
- autotolerance
- specialization
- stimulation of mechanisms of innate immunity
Types of adaptive immunity
Phases of adaptive immune response
Types of lymphocytes
Lymphoid organs
Lymph node structure
