Helper T cells
adaptive immune response
An adaptive immune system is a series of specialized, systemic cells and processes which remove or counter pathogenic growth.
Acquired Immune System or Adaptive immune System
Innate and adaptive.
Also. Allied the innate immune system, cells and proteins involved recognize structures shared by classes of microbes not present on the body's own cells and can also recognize molecules released by infected, damaged, or dead cells. The innate system can eliminate microbes on its own but more commonly cells of the innate immune system release chemokines to attract cells that are involved in the adaptive immune system to initiate an antigen or microbe specific immune response
T helper cells
They're abnormal immune responses - by definition, an allergy is an inappropriate response to a foreign substance. After all, it's not known as an 'allergy' when people's immune systems attack harmful pathogens, despite the body mounting somewhat similar immune responses.
Your immune system.
Generally, they don't engage in cell to cell combat; they are the building blocks of life. However, microbes and invaders do attempt to take over more advanced organisms. That is why there is an immune system. One type of immune cells are the phagocytes, and they surround invaders and "eat" them as their name implies.
antigen and antibodies
The adaptive immune system is activated if the innate immune system is unable to control the infection.

Lymphocytes(T and B cells)
Majority of the microbes do not cause the disease. The disease causing microbes also, probably, keeps your species healthy and your immune system tuned.
Immune system to react and prepare the organism to fight future invasions by these microbes.
Microbes evade the immune system through inhibition of phagocytosis by affecting the receptors that phagocytes use to engulf bacteria or by mimicking host cells so that the immune system does not recognize them as foreign.
