Capitolo 7, Problema 11
Which of the following are considered cytokines? Select all that apply.
a. Eicosanoids
b. TNF- α
c. Interferon β
d. Histamine
e. Chemokines
Guida verificata passo dopo passo1
Step 1: Understand the definition of cytokines. Cytokines are small proteins released by cells, especially immune cells, that act as signaling molecules to regulate immunity, inflammation, and hematopoiesis.
Step 2: Review each option and classify it based on whether it fits the definition of a cytokine. For example, TNF-α (Tumor Necrosis Factor alpha) is a well-known cytokine involved in systemic inflammation.
Step 3: Identify Interferon β as a cytokine because it is part of the interferon family, which are signaling proteins released in response to viral infections.
Step 4: Recognize chemokines as a subset of cytokines that specifically induce chemotaxis in nearby responsive cells, guiding immune cells to sites of infection or injury.
Step 5: Differentiate other options such as eicosanoids and histamine, which are signaling molecules but not classified as cytokines. Eicosanoids are lipid mediators, and histamine is an amine involved in allergic responses.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Cytokines
Cytokines are small proteins secreted by cells, especially immune cells, that regulate immunity, inflammation, and hematopoiesis. They act as signaling molecules to mediate and coordinate immune responses, including cell activation, differentiation, and communication.

Cytokines
Types of Cytokines
Common types of cytokines include interleukins, tumor necrosis factors (e.g., TNF-α), interferons (e.g., interferon β), and chemokines. Each type has specific roles, such as promoting inflammation, antiviral responses, or directing cell movement.

Non-Cytokine Mediators
Not all immune signaling molecules are cytokines. For example, eicosanoids (lipid mediators) and histamine (a biogenic amine) are involved in inflammation but are not classified as cytokines. Understanding these distinctions helps correctly identify cytokines.
