The responses observed in type IV hypersensitivities result from the action of T cells and phagocytes.
Hypersensitivity IV type, also called delayed-type hypersensitivity (DTH), involves T cell-antigen interactions that cause activation and secretion of cytokines. This type of hypersensitivity requires sensitized lymphocytes that respond 24–48 hours after exposure to soluble antigens. A type IV hypersensitivity reaction is a cell-mediated reaction that can occur in response to contact with certain allergens, resulting in what is called contact dermatitis, or in response to certain diagnostic procedures such as the tuberculin skin test. Certain allergens need to be avoided to treat this condition. Type IV hypersensitivity response is observed results from the action of T cells and macrophages while other types are mediated by antibodies. This reaction occurs at least 1–3 days after the initial exposure. Type IV hypersensitivity is the mechanism of many autoimmune disorders.

Enzymes can be denatured unfolded by heat or chemicals.
<h3>What are enzymes?</h3>
Enzymes are proteins that are found in living organisms which are able to increase the rate of chemical reaction and remains unchanged at the end of the reaction.
The factors that can denature enzymes include heat and chemicals. This is because:
- Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. When the enzyme loses its shape, it is said to have been denatured.
- These environmental factors can alter the pH level of the enzyme.
Therefore, for an enzyme to perform its functions, the external factors that affects it's activities must be normal and favorable.

Regarding human traits, Locke would most likely agree with Aristotle.
There are more areas where Aristotle and Locke's philosophical views diverge than where they concur. For instance, Aristotle once claimed that a person's happiness was just as important to them as it was to their political community. The political understanding of Locke, however, is different because, in his view, a government only assumes responsibility for a portion of the human rights that it is meant to protect in accordance with what people deem to be right. Individuals are therefore given priority because they have rights that are inalienable and shouldn't be manipulated by people to fit their agenda. These and other traditional philosophies have been used to analyze and comprehend early philosophy.
