HUBS 191 Lecture 37 Exam Questions and Answers Already Passed Latest Update 2025-2026
Immune deficiencies - Answers Can be inborn or induced by viruses.
Tolerance to self-antigens - Answers Concept preventing immune cells from attacking self-cells.
Effector molecules in allergic reactions - Answers Include IgE, T cells, B cells, and mast cells.
Severe Combined Immunodeficiency (SCID) - Answers X-linked disease causing lack of
functional T and B cells.
Virus-induced immune suppression - Answers Viruses like HIV interfere with host immune
system.
Human immunodeficiency Virus (HIV) - Answers Targets CD4 T cells, impacting immunity.
Vaccines / pathogens components - Answers MHC-I, MHC-II, CD4, CD8, TCR, APC involved.
Autoimmune disease - Answers Mediated by adaptive immune response attacking self-antigens.
Immune tolerance importance - Answers Critical to prevent autoimmunity, involves thymus and
peripheral mechanisms.
Rheumatoid arthritis (RA) - Answers Autoimmune disorder affecting joints, immune cells attack
self-antigens.
Diabetes Type I - Answers Autoimmune attack on insulin beta-cells.
Allergic reactions - Answers Triggered by 'allergens', range from hay fever to anaphylaxis.
Peanut allergies - Answers DC presents peanut antigens to helper T cells, triggering mast cell
degranulation.
Fc receptors - Answers Bind to antibody Fc domain, facilitating phagocytosis and mast cell
activation.
Antibody structure changes - Answers Antigen binding, constant region switching during
immune response.
HIV targets - Answers Targets CD2, CD4, CD8 positive cells.
SCID results in loss of - Answers T cells and B cells.
SCID is - Answers Inborn / genetic / inherited.
