Study Notes

Understanding Immunity and Immune Responses

  • Immunity is the body's ability to fight infectious diseases.
  • Three types of antigens include bacteria/self antigens, virus/non-self antigens, and allergens.
  • Specific immune response involves cell-mediated and humoral immunity.
  • Non-specific immunity describes the first and second lines of defense.
  • Histamine is released whenever there is tissue injury and causes arteriole dilation and increased capillary permeability.
  • Humoral immunity is B cell-mediated and defends against circulating antigens by producing antibodies.
  • Adaptive immunity involves T cells and B cells, with B cells produced in the bone marrow.
  • Antibodies, also known as immunoglobulins, are specific for foreign antigens and label them for destruction.
  • Inflammation is the body's response to tissue injury and is mediated by chemicals like histamine.
  • The power of an organism to overcome the host is called immunity.
  • AIDS is caused by a retrovirus called HIV and infects helper T cells.
  • Different types of immunity include active and passive, with active immunity resulting in memory B cells and T cells, and passive immunity involving the administration of antibodies without memory cell production.
