While we usually think of fever as a bad thing, a fever is actually signifying that an immune response is progressing! Overall,
which of the following cytokines would be most involved in increasing Caleb's fever response? a. Interleukin-4
b. Interleukin-12
c. Interleukin-10
d. Interleukin-2
e. Interleukin-1
Interleukin-1 is produced by macrophages and is involved in promoting the proliferation of helper T cells. Interleukin-1 also acts on the hypothalamus to cause fever. Fever refers to abnormally high body temperature. During infection and inflammation, the hypothalamic thermostat is reset in response to interleukin-1 resulting in fever. The presence of certain bacterial toxins in the body triggers the release of interleukin-1 from macrophages and the body temperature is elevated. Fever inhibits the growth of some microbes, intensifies the effects of interferons, and stimulates the body's immune reactions.
Species interactions within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism).
