Abstract in brief

  • The immune system plays a crucial role in defending the body against pathogens using various strategies, but sometimes its responses can be overly aggressive or harmful.
  • "Hypersensitivity" refers to an excessive immune response to foreign or self antigens that can lead to damage.
  • Gell and Coombs initially categorized hypersensitivity reactions into four types, but advancements in understanding these mechanisms have led to updated classifications, which are explained in this review.
