ACKR2 (Atypical Chemokine Receptor 2): ACKR2 is a receptor, also known as D6, that functions in an unconventional way by scavenging chemokines from the environment rather than signaling through typical pathways. This activity is essential for regulating inflammatory responses and maintaining immune balance. By clearing chemokines, ACKR2 plays a key role in controlling inflammation and has been linked to various inflammatory conditions, including asthma, psoriasis, and cancer.
