DÖRING LAB

We focus on chemokine(-receptor) crosstalk with leukocytes and vascular cells in cardiovascular diseases.
Projects:
Roles of CXCL12 and its receptors CXCR4 and ACKR3 in chronic arterial vascular inflammation.
ChemR23-mediated vascular immune responses in cardiovascular disease

CCR8-Tregs (NCR)
Recently, we identified a novel interaction of CCR8 expressed on CD4+ T cells and CCL17 in driving atherosclerosis. Specifically, we showed that CCR8-CCL17 interaction restraint Treg suppressive function via CCL3 release binding to CCR1 on Tregs. Conversely, blockade of CCR8 decreased CCL3 levels and attenuated atherosclerotic lesion development concomitant with an increase in Treg numbers (Döring et al., 2024, Nat Cardiov Res).

CCR8-ILC2
Importantly, CCR8 is also highly expressed on ILC2s. Therefore, we are examining the role of CCR8 on ILC2s in chronic vascular inflammation. In particular, we are interested in (adipose-)tissue crosstalk of ILC2s via chemokines and their receptors in atherosclerosis.

CXCL13-CXCR5 dyad, CXCR4 and B cells in atherosclerosis.
We recently described a proatherogenic role of the CXCL13-CXCR5 dyad in atherosclerosis, an effect that is likely attributable to its impact on B1 cells and their IgM production.
Similarly, we could show that expression of the chemokine receptor CXCR4 on B1 cells controls IgM titers and thereby mediated atheroprotection underlining the importance of B1 cell–derived IgM in atheroprotection.

ACKR3 and Dysfunctional adipose tissue
Dysfunctional adipose tissue may contribute to the pathology of several metabolic diseases. Hence, we explored the role of ACKR3 in adipocyte-specific knockouts of Ackr3 in ApoE-deficient mice in order to determine its impact on lipid levels under hyperlipidemic conditions. Adipocyte-specific deletion of Ackr3 results in reduced AT triglyceride and cholesterol content in ApoE-deficient mice, which coincides with increased PPAR-γ and Angptl4 expression. The role of adipocyte ACKR3 in lipid handling seems to be tissue-specific as hepatocyte ACKR3 deficiency did not demonstrate comparable effects.
