Across
  1. 4. The study of diseases caused by problems with the immune system, either overactive or underactive responses.
  2. 6. A weakened or poorly functioning immune system that cannot fight infections effectively.
  3. 7. A substance (usually harmless) that triggers an allergic reaction in sensitive individuals.
  4. 10. A genetic disorder where both B and T cells do not function properly, leaving the body extremely vulnerable to infections.
  5. 11. Immediate allergic reaction involving IgE antibodies and mast cells (ex: asthma, anaphylaxis).
  6. 12. A condition that occurs after a transplant when the donated (graft) immune cells attack the recipient’s body tissues because they recognize them as foreign.
  7. 13. A chronic, localized allergic condition such as hay fever or asthma.
  8. 15. A delayed immune response involving T cells that damage tissues (ex: contact dermatitis, transplant rejection).
Down
  1. 1. A condition where the immune system mistakenly attacks the body’s own cells and tissues.
  2. 2. An immune reaction where antibodies attack cells, leading to cell destruction (lysis).
  3. 3. A reaction caused by immune complexes (antigen-antibody clusters) depositing in tissues and causing inflammation.
  4. 5. Immune cells that release histamine and other chemicals during allergic reactions.
  5. 7. A severe, life-threatening allergic reaction that can cause airway blockage and shock.
  6. 8. An overactive immune response that damages the body’s own tissues (like allergies or autoimmune diseases).
  7. 9. The idea that lack of exposure to microbes early in life can lead to more allergies due to poor immune system “training.”
  8. 14. A chemical released during allergic reactions that causes inflammation, itching, and swelling.
