ACKR1 (Atypical Chemokine Receptor 1): ACKR1, formerly known as Duffy antigen receptor for chemokines (DARC), acts as a decoy receptor that binds chemokines without signaling. It modulates the immune response by sequestering chemokines, affecting leukocyte migration. ACKR1 is also known for its role in malaria resistance, as it serves as a receptor for Plasmodium vivax. Variations in ACKR1 can influence susceptibility to infection and autoimmune diseases, highlighting its role in immunity and disease....
