PROTECTION FROM DISEASE/INFECTIOUS DISEASE

THE CELLS & MOLECULES RESPONSIBLE FOR IMMUNITY

THE IMMUNE SYSTEM'S COLLECTIVE & COORDINATED RESPONSE TO THE INTRODUCTION OF FOREIGN SUBSTANCES

THE STUDY OF IMMUNE RESPONSES & OR THE CELLULAR & MOLECULAR EVENTS THAT OCCUR AFTER AN ORGANISM ENCOUNTERS MICROBES OR FOREIGN MACROMOLEULES.

THE CELLULAR & BIOCHEMICAL DEFENSE MECHANISMS THAT ARE IN PLACE EVEN BEFORE INFECTION & ARE POISED TO RESPOND RAPIDLY TO INFECTIONS.

THE PRINCIPAL COMPONENTS OF INNATE IMMUNITY.

FORM OF IMMUNITY THAT DEVELOPS AS A RESPONSE TO INFECTION AND ADAPTS TO THE INFECTION.

THE MAIN COMPONENT OF ADAPTIVE IMMUNITY.

FOREIGN SUBSTANCES THAT INDUCE SPECIFIC IMMUNE RESPONES OR ARE THE TARGET OF A RESPONSE.

TYPE OF ADAPTIVE IMMUNE RESPONSE THAT IS MEDIATED BY MOLECULES IN THE BLOOD & MUCOSAL SECRETIONS.

TYPE OF ADAPTIVE IMMUNE RESPONSE THAT IS MEDIATED BY T LYMPHOCYES.

THE FORM OF IMMUNITY THAT IS INDUCED BY EXPOSURE TO A FOREIGN ANTIGEN.

INDIVIDUALS & LYMPHOCYTES THAT HAVE NOT ENCOUNTERED A PARTICULAR ANTIGEN.

INDIVIDUALS WHO HAVE RESPONDED TO A MICROBIAL ANTIGEN & ARE PROTECTED FROM SUBSEQUENT EXPOSURES TO THAT MICROBE.

FORM OF IMMUNITY WHICH IS DONE BY ADOPTIVE TRANSFER.

SERUM PROTEINS THAT MEDIATE HUMORAL IMMUNITY.

SUBSTANCES THAT BOUND ANTIBODIES AND GENERATE THE PRODUCTION OF ANTIBODIES.

THE PARTS OF ANTIGENS THAT ARE SPECIFICALLY RECOGNIZED BY INDIVIDUAL LYMPHOCYTES.

THE TOTAL NUMBER OF ANTIGENIC SPECIFICITIES OF THE LYMPHOCTYES IN AN INDIVIDUAL.

THE RESULT OF VARIABILITY IN THE STRUCTURES OF THE ANTIGEN-BINDING SITES OF LYMPHOCYTE RECEPTORS FOR ANTIGENS.

AN INCREASE IN THE NUMBER OF CELLS THAT EXPRESS IDENTICAL RECEPTORS FOR THE ANTIGEN & THUS BELONG TO A CLONE.

THE RETURNING OF THE IMMUNE SYSTEM TO ITS RESTING BASAL STATE.

IMMUNOLOGICAL UNRESPONSIVNESS.

ABNORMALITIES IN THE INDUCTION OR MAINTANCE OF SELF-TOLERANCE LEADING TO IMMUNE RESPONSES AGAINST SELF ANTIGENS.

THE ONLY CELLS CAPABLE OF PRODUCING ANTIBODIES.

THE CELLS OF CELL-MEDIATED IMMUNITY, THEY RECOGNIZE THE ANTIGENS OF INTRACELLULAR MICROBES AND FUNCTION TO DESTROY THESE MICROBES.

THE 2 FUNCTIONALLY DISTINCT POPULATIONS OF THE T LYMPHOCYTES.

A CELL THAT DISPLAYS PEPTIDE FRAGMENTS OF PROTEIN ANTIGENS ON ITS SURFACE AND ACTIVATES ANTIGEN-SPECIFIC T-CELLS.

CELLS THAT MEDIATE THE FINAL EFFECT OF THE IMMUNE RESPONSE, GET RID OF THE MICROBE.

THE HYPOTHESIS THAT ANTIGEN-SPECIFIC CLONES OF LYMPHOCYTES DEVELOP BEFORE AND INDEPENDENT OF EXPOSURE TO ANTIGEN.
