What is released from damaged cells in the immune response?LeukotrienesHistamineArachidonic Acid LipooxygenaseCyclooxygenase

When cells are damaged, they release several substances as part of the immune response. Here's a step-by-step breakdown:

1. Arachidonic Acid: This is a type of fatty acid that is released from the phospholipids of the cell membrane when cells are damaged. It serves as a precursor to several important compounds involved in the immune response.

2. Cyclooxygenase: This is an enzyme that converts arachidonic acid into prostaglandins and thromboxanes. These molecules play a role in inflammation, fever, and pain, which are all part of the immune response.

3. Lipooxygenase: This is another enzyme that converts arachidonic acid, but it produces leukotrienes instead. Leukotrienes are involved in the inflammatory response, particularly in the lungs.

4. Leukotrienes: These are produced by the action of lipooxygenase on arachidonic acid. They cause constriction of airway muscles and increase the production of mucus in the lungs, contributing

When cells are damaged, they release several substances as part of the immune response. Here's a step-by-step breakdown:

2. Cyclooxygenase: This is an enzyme that converts arachidonic acid into prostaglandins and thromboxanes, which are both involved in the inflammatory response.

3. Lipooxygenase: This is another enzyme that converts arachidonic acid, but into leukotrienes.

4. Leukotrienes: These are inflammatory mediators that are produced as a result of lipooxygenase acting on arachidonic acid. They help to promote inflammation and are particularly involved in asthmatic and allergic reactions.

5. Histamine: This is a substance that is released by cells in response to injury and in allergic and inflammatory reactions, causing contraction of smooth muscle and dilation of capillaries.

So, in summary, damaged cells release arachidonic acid, which is then converted by cyclooxygenase and lipooxygenase into prostaglandins, thromboxanes, and leukotrienes, respectively. Histamine is also released as part of the immune response.
