Question

Members of the cytokine family fall into two broad groups - CC chemokines with two adjacent cysteines, and CXC chemokines, in which the equivalent two cysteine residues are separated by another amino acid. The two groups of cytokines act on different sets of receptors and different cell types; in general, the CXC chemokines promote the migration of neutrophils, whereas the CC chemokines promote the migration of monocytes or other cells types. What is an example of a CC chemokine?

VCAM-1
MCP-1
Mac-1
LFA-1
ICAM-1

Answer 1

(2) MCP-1 is an example of a CC chemokine that recruits leukocytes to infected or inflamed areas, having a key role in the body's immune response.

Step-by-step explanation:

An example of a CC chemokine is MCP-1, which stands for Monocyte Chemoattractant Protein-1. Chemokines like MCP-1 are chemotactic cytokines that play crucial roles in recruiting specific subsets of leukocytes to areas of infection, damaged tissue, and sites of inflammation.

The CC chemokines, including MCP-1, are characterized by having two adjacent cysteines near their amino terminus and are known to promote the migration of monocytes and other cell types, playing a fundamental part in both early induced responses and adaptive immune responses.
