How much do you know about Chemokines

• Chemokines are small proteins secreted by immune cells that allow for the movement of immune cells to sites of infection
• Chemokines are regulated by gene-protein coupled receptors (GPCRs)
• CCR5 is a chemokine receptor found on the surface of white blood cells
• CCR5 plays a role in the body's inflammatory responses to infections and acts as a co-receptor for HIV-1
• The CCR5-∆32 mutation results in a protein that cannot be detected on the cell surface and provides resistance to HIV-1 infections
• The global distribution of CCR5-∆32 is greater in European populations, but the first HIV transmission was traced back to Africa
• Other illnesses, such as the black plague or smallpox, may have been involved in the selection for the CCR5-∆32 allele
• CCR5-∆32 is not the only factor in HIV-1 resistance
• Chemokines and their receptors play a crucial role in the immune system's response to infections
• Understanding the role of chemokines and their receptors can lead to the development of new treatments and therapies for infectious diseases.
