The inside of the eye, the brain, and the testes are parts of the body that are not directly exposed to the immune system. They are protected by barriers like the blood-brain barrier and the blood-testis barrier, which prevent direct contact with immune cells.
Using fear and violence for political gain most directly affected African Americans.
What are the parts of the cell directly involved or affected by mitosis?
Because this response by the immune system occurs in the deeper layers of the skin, the hair follicles, sweat glands, and nerves can be destroyed.
the parts of the human immune system. It has three parts: cellular, humoral, and nonspecific.
Protists are not commonly used in the development of vaccines. Vaccines are typically made using viruses, bacteria, or parts of these organisms to stimulate the immune system to produce an immune response. Protists are a diverse group of eukaryotic microorganisms, but their use in vaccines is limited.
The immune system recognizes germs thanks to specialized cells and molecules that can identify the foreign invaders. Once identified, the immune system activates a response to eliminate the germs from the body. This recognition and rejection process is crucial for protecting the body against infections and maintaining overall health.
The immune system.
I suspect you mean chloroplast. These are the parts of plant cells that do photosynthesis, most fatty acid synthesis and some immune response. For more information please see the chloroplast wikipedia article.

Primary versus Secondary Immune ResponseThe primary immune response occurs the first time that the immune system comes in contact with the antigen. During this time the immune system has to learn to recognize antigen and how to make antibody against it and eventually gain immunological memory. This primary response takes time (about two weeks) and during this time the person experiences signs of illness. IgM antibodies are the hallmark of a new infection because they are the first antibodies made when a person is exposed to an antigen for the first time. After the body learns to make IgM antibodies, it will start making IgG antibodies to the antigen.The secondary immune response occurs the second time (3rd, 4th, etc.) the person is exposed to the same antigen. At this point immunological memory has been established and the immune system can start making antibodies immediately. The antigen usually is killed within minutes and the person is not aware that he/she was attacked. The antibodies in this response are IgG and IgA or (in the case of allergy IgE).
