The immune system defends the body against pathogens like viruses. This simulation shows how antibodies identify and neutralize viruses, while T cells coordinate the immune response. Understanding these processes is crucial for developing vaccines and treatments.
Y-shaped proteins produced by B cells that bind to specific antigens on pathogens, marking them for destruction or neutralizing them directly.
White blood cells that coordinate immune responses. Helper T cells activate other immune cells, while Killer T cells destroy infected cells.
Infectious agents that invade host cells, hijack cellular machinery to replicate, and can cause various diseases.
Unique molecular markers on pathogens that antibodies recognize and bind to, triggering an immune response.
Immune cells identify foreign invaders through antigen recognition.
T cells activate B cells to produce specific antibodies.
Antibodies neutralize pathogens and mark them for destruction.
Memory B and T cells remain for faster future responses.
Vaccines train the immune system by presenting harmless antigens.
When the immune system mistakenly attacks self-antigens.
Cancer treatments that boost immune system to attack tumors.
Medications that interfere with viral replication.
