Project 5 Myeloid Cells
Myeloid cell function in corneal hem- and lymphangiogenesis
Influx and activation of myeloid cells represent early defense mechanisms after tissue injury. The primary function of this process is to mount an immune response that effectively kills invading pathogens, and at the same time, induces successful repair and homeostasis of the damaged tissue. Our previous work in cornea and skin wound healing provides substantial evidence for a dual role of myeloid cell-mediated hem- and/or lymphangiogenesis in both beneficial but also harmful effects leading either to an effective repair response or causing disease. In skin we recently provided novel mechanistic insights into the recruitment of blood monocyte subsets into damaged tissue and their differentiation in diverse monocyte/macrophage phenotypes with specific functions during the sequential stages of skin repair. In corneal injury the mechanisms of blood monocyte recruitment, their activation in different macrophage phenotypes and functional consequences of this process for hem-/lymphangiogenesis are not understood so far. The overall goal of this project is to investigate the specific role of myeloid cells in hem- and lymphangiogenesis in acute and chronic corneal tissue damage. Specifically, we will identify the functional impact of myeloid cells on the induction and regression of vascular structures in corneal injury. Furthermore, we will examine the functional relevance of myeloid cell-restricted chemokine (C-C-motif) receptor 2 (CCR2) in the recruitment of blood monocytes into the injured cornea and their differentiation into macrophage subsets with specific functions during hem-/lymphangiogenesis. Together, this work will provide deeper insight into the functional relationship between monocytes/macrophages and vascular growth, and should contribute to future immunomodulatory therapeutic interventions promoting repair and/or preventing disease.
