Final answer:
The CC subfamily of chemokines, important for recruiting leukocytes to sites of inflammation or damage, includes MCP-1, RANTES, Eotaxin, SDF-1, and Lymphotactin. The option (D) is correct.
Step-by-step explanation:
Chemokines are chemotactic cytokines that play an essential role in the immune system by recruiting specific subsets of leukocytes to areas of infection, damaged tissue, or inflammation. The CC subfamily of chemokines, which includes MCP-1, RANTES, and Eotaxin, are among the molecules involved in these processes.
These chemokines are crucial in various disease states such as arthritis, angiogenesis, arteriosclerosis, and asthma, where they aid in the mobilization and activation of blood leukocytes. SDF-1 and Lymphotactin are also part of the CC subfamily. Therefore, option (D) is correct.
This question is not complete, Here I am attaching the complete question:
Chemokines are an important group of proteins that play a major role in the mobilization and activation of blood leukocytes. They are produced in various disease states involving acute and chronic inflammatory processes, including arthritis, angiogenesis, arteriosclerosis and respiratory processes such as asthma. The CC subfamily of chemokines include MCP-1, RANTES, and what else?
(A) IL-8
(B) Mac-1
(C) Eotaxin
(D) SDF-1
(E) Lymphotactin
