Answer:
Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells. As dramatically demonstrated in AIDS patients, without helper T cells we cannot defend ourselves even against many microbes that are normally harmless.
Helper T cells themselves, however, can only function when activated to become effector cells. They are activated on the surface of antigen-presenting cells, which mature during the innate immune responses triggered by an infection. The innate responses also dictate what kind of effector cell a helper T cell will develop into and thereby determine the nature of the adaptive immune response elicited.
In this final section, we discuss the multiple signals that help activate a T cell and how a helper T cell, once activated to become an effector cell, helps activate other cells. We also consider how innate immune responses determine the nature of adaptive responses by stimulating helper T cells to differentiate into either TH1 or TH2 effector cells.
It is important to help people who don’t have food because they can die or starvation or dehydration. The human body is 60% water. 79% muscles and kidneys, 64% skin, and 73% brain and heart. If the people don’t have food their percentage will decrease.
Because malaria is caused by Plasmodium parasites brought on by bites of infected mosquitos, countries should use vector control. Two forms of vector control are insecticide-treated nets and indoor residual spraying. Both are effective in a wide range of circumstances.
