EXAMS & QUIZZES

EXAMS

sit-down, written exam; class hours

objective and critical thinking type

QUIZZES

individual, pair, group, class quizzes

written, oral or take-home

no make-up for missed quizzes!


CLASS plenary

CONFERENCE-TYPE OF PAPER PRESENTATIONS

3 PAPERS: VACCINE CHALLENGES (HIV, pandemics, vector-borne or zoonotic diseases)

TASKS: Speakers, Master of Ceremonies, Moderator, Reactors, Technical Group, Logistics Group, Refreshments Group, Press Group, etc

CLASS GRADE: Absent during the presentation is given a ZERO (0) mark


your grade

PFG = lecture (60%) + laboratory (40%) rating

NOTE: This will be the final grade when exempted to take the final exams.

If the student will take the finals the rating will be computed as follows, which should be no lower than 60% or 3.0:

RATING = PFG (80%) + Score in Finals Exam (20%)


OUR TEXTBOOK

Abbas, Abul K. and Andrew H. Lichtman. 2004. Basic Immunology: Function and Disorders of the Immune System. 2nd ed.


POLICIESThe student should be able to pass (PFG = 3.0) both lecture and laboratory component to pass the course

There will be no make-up exams, missed exams will qualify students to take the final examination. The score in the final exam may replace the missed exam. However, in the case of two missed exams, the other exam will have a score of zero (0)

The student should be able to incur a PFG of 2.0 or better to be exempted to take the written final exam

Should the student fail the final exam, an oral removal exam to satisfy the course competencies will be given to pass the course. The grade to be given here shall only be a “pass” (3.0) or “fail” (5.0)

OJT: IMMUNE CELLS


OUR IMMUNE SYSTEMPhysiologic function of the immune system:

prevent infections

eradicate established infections


vaccines: stimulation of our Immune System

OUR IMMUNE SYSTEM


INNATE: immunity which mediates the initial protection against infections

always present in health individuals

block the entry of microbes and rapidly eliminate microbes that do succeed in entering host tissues

ADAPTIVE: immunity which!develop more slowly and mediates innate immunity

more effective defense against infections

specific or acquired

stimulated by microbes that invade tissues

adapts to the presence of microbial invaders

overview: host defense mechanisms


overview: host defense mechanisms


OVERVIEW: HUMORAL & CELL-MEDIATED IMMUNITY


NOTE: ADAPTIVE RESPONSE

Immunity may be induced in an individual by infection or vaccination (active immunity) or conferred on an individual by transfer of antibodies or lymphocytes from an actively immunized individual (passive immunity)


SPECIFICITY & MEMORY


OVERVIEW: PHASES OF ADAPTIVE IMMUNITY


MAJOR CHARACTERS OF THE IMMUNE SYSTEM


THE EFFECTOR FUNCTIONS


When naive lymphocytes recognize microbial antigens and also receive additional ("second) signals induced by microbes, the antigen-specific lymphocytes proliferate and differentiate into effector cells and memory cells

Naive lymphocytes express receptors for antigens but do not perform the functions that are required to eliminate antigens

Differentiation into effector cells and memory cells is initiated by antigen recognition, thus ensuring that the immune response that develops is specific for the antigen
